Cardiogenic shock - Impella 2.5, CP, 5.0, LD - Temporary VAD for less than or equal to 4 days: 2.5, CP - Temporary VAD for less than or equal to 14 dyas: 5.0, LD to maintaining your privacy and will not share your personal information without Impella heart pumps have been tested under simulated conditions of inflow and outflow obstruction. When the physician is ready to discontinue the Impella 2.5 catheter, the groin dressing should be removed, the site cleansed with chloroprep, and the sutures clipped. Work with pharmacy and nursing staff to develop a standardized time for fluid and tubing changes. Function keys that are used with the Impella 2.5 include the P-PERF, MENU, SIGNAL, SCALE, and the ON keys. The patient was transferred to the CICU for continued monitoring. Percutaneous Mechanical Circulatory Support Devices for High-Risk Percutaneous Coronary Intervention. Slow weaning is accomplished by decreasing the performance level by 1 or 2 levels every 2 or 3 hours. Introduction. More blood products were administered to patients treated with the Impella. Some facilities may use what is referred to as a preclose method while the patient is still in the catheterization laboratory; that technique uses 2 8F Perclose suture-mediated closure devices (Abbott Laboratories, Abbott Park, Illinois). The performance level should be decreased to P2 and the physician should be notified to reposition the device by pulling it back slightly to obtain an aortic waveform. Crowley J, Cronin B, Essandoh M, DAlessandro D, Shelton K, Dalia AA: Transesophageal echocardiography for, 2. Wolters Kluwer Health Adequate blood flow was reestablished after the intracoronary administration of 500 g nitroglycerin. With the Impella continuing at maximum flow of 2.5 L, 2 bare metal stents were deployed in the SVG to the posterior lateral branch. The impellar blades of the motor could break up the thrombi, causing arterial embolization. A culprit oriented approach should be used when troubleshooting the Impella supported patient with signs of persistent circulatory failure. Routine management of patients after PCI is not addressed. Bivalirudin was administered for anticoagulation, and the Impella 2.5 was advanced into position in the left femoral artery. In the Impella LD, 5.0, and RP, the placement signal is a differential pressure waveform that is measured from the differential pressure sensor. Cardiogenic shock was defined as a (1) systolic blood pressure 90 mm Hg or need for inotropes or vasopressors to maintain systolic blood pressures 90 mm Hg, (2) signs of peripheral hypoperfusion, and (3) cardiac index <2.2 L/min/m 2 and pulmonary capillary wedge pressure 15 mm Hg. The use of continuous cardiac output monitoring may be useful for patients with cardiogenic shock. The IABP decreases after-load, decreases myocardial oxygen consumption, increases coronary artery perfusion, and modestly enhances cardiac output.1,2 The IABP cannot provide total circulatory support. A multi-beat acquisition of the catheter should be obtained while panning through the LV cavity, to avoid catheter foreshortening and consequent incorrect assessment of catheter depth. The Impella mechanical circulatory support (MCS) system is a catheter-based continuous flow cardiac assist device that is widely used in the treatment of cardiogenic shock in medical and surgical cardiac intensive care units. Careers. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). The Impella TM is a percutaneous, microaxial pump that continuously draws blood from its inlet inside the ventricle and expels it in the ascending aorta (Central Illustration) (12-15).Owing its properties, the Impella TM unloads the left ventricle (LV) while simultaneously augmenting cardiac output (CO). Train a core group of nurses and cardiovascular technologists from the catheterization laboratory for initial setup of the console, catheter preparation, and assisting with placement of the device. However, in severe cases of RV failure or when pre-capillary pulmonary hypertension is a contributing factor, right-sided MCS and pulmonary vasodilator titration may be required, respectively. This arrangement allows rapid initial setup of the console so that support can be initiated quickly. We have 2 nurses at the bedside for the tubing change. What Does A Swollen Uvula Mean | Buoy - Buoy Health We review Impella and other percutaneous devices such as intra-aortic balloon pump, TandemHeart, and extracorporeal membrane oxygenation (ECMO) and the evidence supporting their use in the setting of CS. On arrival, his blood pressure was 105/66 mm Hg with a heart rate of 64/min. There is currently no consensus on best practice regarding its use in these two distinct indications. Suboptimal Impella flow and suction events can be caused by anything that reduces blood flow to the device, which is most commonly due to hypovolemia, RV failure, ventricular arrhythmias, and obstructive physiology (tamponade, pulmonary embolism, etc. Keyword Highlighting A tubing system called the Quick Set-Up has been developed for use in the catheterization laboratory. Further to this point, cases of Impella weaning intolerance or clinical decompensation after explantation beg the complicated question of when to consider escalating inotropes and/or pursuing additional MCS as bridge-to-recovery or bridge-to-LVAD/transplant versus palliation, and must be determined on an individual basis. She was evaluated by our cardiac surgery team, who thought that she was a very high-risk candidate for surgery based on the recent fibrinolytic therapy, her renal failure, and the remote history of stroke. However, in our experience, measuring structures that can be directly visualized with ultrasound is a more practical and reproducible strategy, and thus we recommend measuring from the aortic annulus to the end of the railroad tracks. We follow our hospitals protocol for achieving hemostasis, using either manual or mechanical compression. *; Barnett, Christopher F.; Tuli, Aakash; Vavilin, Ilan; Kenigsberg, Benjamin B. Optimizing the spatial relationship between the catheter and adjacent intracardiac structures is necessary to minimize device-related complications. Explore Impella Technology - Abiomed 23. Cardiogenic Shock | Hospital Handbook During stent deployment, the patient had severe chest pain and showed ST-segment elevation in the anterior leads. He was evaluated by our cardiothoracic surgery team and was deemed an extremely poor candidate for surgery. Echocardiography for Evaluating Impella Catheter Position Following cardiac intensive care unit; cardiogenic shock; Impella; mechanical circulatory support. Patients on Impella 2.5 support who may require interrogation of a permanent pacemaker or implantable cardioverter defibrillator present an interesting situation. Just before the patients return to the CICU, the pulmonary artery pressure decreased to 70/4148 mm Hg and the cardiac index was 2.69. %PDF-1.4 % A broad mosaic color Doppler pattern caused by artifact from the motor will be seen, which should be limited to the aortic side of the valve. Quick Reference and Troubleshooting Guide Impella Heart It is used for high-risk percutaneous coronary intervention and CS. The components required to run the device are assembled on a rolling cart (Figure 6) and include the power source, the Braun Vista infusion pump, and the Impella console (Figure 7). Notably, catheter position is best assessed ultrasonographically, as radiography does not accurately identify the cannula position relative to cardiac anatomic structures. Device profile of the Impella 5.0 and 5.5 system for mechanical circulatory support for patients with cardiogenic shock: overview of its safety and efficacy. Read below to find out how long a swollen uvula lasts and how to get treatment. If Impella malposition is suspected, use echo to look for inlet or outlet obstructions. The Impella is placed percutaneously, most commonly via the femoral or axillary artery, into the aorta, and across the aortic valve. Additional torque can be achieved by rotating the red Impella plug (Figure 5) at the proximal end of the catheter in the desired direction. 0000006172 00000 n Device-related complications occur more frequently with a longer duration of support. Our practice is to integrate clinical factors, such as mean arterial pressure, heart rate, and urine output with invasive hemodynamics, and lab dataspecifically, serum lactate and pulmonary arterial oxygen saturation every 6 hours. The aortic end of the cannula houses a microaxial motor which spins an Archimedes screw impeller that draws blood through the cannula to the outlet area in the aortic root. The device received 510(k) clearance from the Food and Drug Administration in June 2008 for providing up to 6 hours of partial circulatory support. Suboptimal Impella flow and suction events can be caused by anything that reduces blood flow to the device, which is most commonly due to hypovolemia, RV failure, ventricular arrhythmias, and obstructive physiology (tamponade, pulmonary embolism, etc.). To date, we have placed an Impella 2.5 in about 40 patients. On imaging, if the LV appears overly decompressed due to a significant interventricular septal shift, then reducing the Impella speed, escalating inotropy to support the RV, and increasing volume removal is commonly the best course of action. If the patient tolerates this slow weaning by remaining hemodynamically stable while at P2, the device is then removed. The Impella 2.5 should not be used in patients with aortic valve disease or known left ventricular thrombus. 1. Once perfusion goals are met and proven to be stable at power level P2, the Impella catheter should be removed. Context 1. . The placement monitoring diagram will continuously scroll through 3 different images because it is not able to differentiate the position of the catheter. None of the patients had hemodynamic instability develop during the procedure. Impella 2.5 cardiac assist device in left ventricle. He had a long history of diabetes and had undergone coronary artery bypass surgery 20 years prior. Potential complications of use of the Impella 2.5 are detailed in Table 3. Expert commentary: The optimal cannula depth of the Impella 5.5 is 4.5 cm +/- 0.5 cm to the beginning of the inlet area, as this model has a longer cannula. Free shipping for many products! Unlike the IABP, the Impella does not require timing, nor is a trigger from an electrocardiographic rhythm or arterial pressure needed (Table 1). As with all current forms of MCS, device-related complications remain a major concern, many of which can be mitigated by adhering to a few fundamental concepts in device management. The purpose of this review is to describe how to manage, reposition, and wean patients from the Impella catheter. When activated, the console is silent. Ventricular Assist Device (VAD) LITFL CCC Equipment Signs of pulmonary congestion should be monitored, as, at least in theory, high Impella RP support with reduced LV function could cause overflow and pulmonary congestion. Impella heart pumps (Abiomed) are intravascular microaxial blood pumps that provide temporary MCS during HRPCI or in the treatment of cardiogenic shock. echocardiography (right). Repositioning is best performed under fluoroscopic guidance, whenever possible. SyBbhD&,V}R#Ohov]F}9v_c- The PROTECT I study was done to assess the safety and efficacy of device placement in patients undergoing high-risk PCI.10 Twenty patients were enrolled in that prospective, multicenter study. Suction alarms can occur if the performance level is too high for the patient; for example, in a patient who is hypovolemic or if the device is emptying the ventricle. It is used for high-risk percutaneous coronary intervention and CS. b)x""o0``k1h^xyW eCollection 2020 Jan. Barrionuevo-Snchez MI, Ariza-Sol A, Ortiz-Berbel D, Gonzlez-Costello J, Gmez-Hospital JA, Lorente V, Alegre O, Lla I, Snchez-Salado JC, Gmez-Lara J, Blasco-Lucas A, Comin-Colet J. J Geriatr Cardiol. Heparin 7000 units was administered intravenously for anticoagulation. The Impella 2.5 cannot be used on all acutely ill patients who require hemodynamic support.14 Because the device is designed to sit across the aortic valve in the left ventricle, it should not be used in patients who have prosthetic aortic valves, so as to prevent damage to the valve. The Impella controller will alarm when it determines that the device may be mispositioned or dysfunctional. The patient was rapidly weaned from the Impella, which was removed in the catheterization laboratory. Impella - critical care notes The placement signal will display either an aortic pressure waveform (correct position) or ventricular pressure waveform (incorrect position) depending on the position of the fiber-optic sensor. Cardiogenic shock; Impella; Mechanical support devices; intra-aortic balloon pump; mechanical circulatory support; percutaneous ventricular assist device. Device failure, although not often reported, can occur. Frontiers | Central Venous Pressure and Clinical Outcomes During Left The Impella console powers the microaxial blood pump and monitors the functioning of the device, including the purge pressure and several other parameters. The Impella 2.5 catheter is placed percutaneously through the common femoral artery and advanced retrograde to the left ventricle over a guidewire. If the patient tolerates the PCI procedure and hemodynamic instability does not develop, the Impella 2.5 may be removed at the end of the case while the patient is still in the catheterization laboratory. Ten different performance levels ranging from P0 to P9 are available (Table 5). In these illustrations, the Impella Catheter is positioned correctly. At first, an effort should be made to identify and treat these conditions (Fig. The structural design of each of these LV support catheters is grossly similar (Figure 2). The performance level was increased from P0 to a maximum of P8 in a matter of minutes. Image courtesy ABIOMED Inc, Danvers, Massachusetts. government site. PMC The aortic valve symbols will not be seen on the placement monitoring diagram. Furthermore, crowding of the inlet or outlet areas increases shear stress on the red blood cells pumped through the cannula, accelerating the rate of hemolysis caused by the device. 597 17 bXSG. Frequent hemodynamic evaluation is needed. After advancement, always remove any slack by slowly pulling back on the catheter until cannula movement is observed. 2017 Nov;45(11):1922-1929. doi: 10.1097/CCM.0000000000002676. With the physician at the bedside, transthoracic echocardiography is performed and the pumps performance level is decreased. a1 National Center for Biotechnology Information His ventricular function was poor with a calculated ejection fraction of 20%. No reflow is a phenomenon in PCI that can cause severe hemodynamic compromise because myocardial perfusion through a given segment of the coronary circulation is inadequate, yet no angiographic evidence of mechanical obstruction of the vessel is apparent.15 The patients pulmonary artery pressures increased to 93/4058 mm Hg and the cardiac index decreased to 2.2. Epub 2020 Dec 28. 8600 Rockville Pike The left main lesion was crossed, and one stent was deployed at the lesion. Diastolic LV numbers are also very negative and the Max and Min flows displayed on the console are lower than expected. Consider when SBP <90 mmHg sustained for >30 min (or vasopressors required) AND clinical or objective signs of tissue hypoperfusion (see below). For more information, please refer to our Privacy Policy. Please enable it to take advantage of the complete set of features! Perioperative Management of Patients Receiving Short-term Mechanical It reduces myocardial oxygen consumption, improves mean arterial pressure, and reduces pulmonary capillary wedge pressure.2 The Impella provides a greater increase in cardiac output than the IABP provides. Szymanski TW, Weeks PA, Lee Y, et al. When the patient is coming off of cardiopulmonary bypass, the performance level of the Impella pump, if the pump remains in place, must be increased to provide adequate flow to the patient. The Impella catheter connects to a bedside controller that displays data about device performance, powers the motor, and delivers a heparinized dextrose solution (purge fluid) to the motor housing. HHS Vulnerability Disclosure, Help The patients remaining hospital course was uneventful and he was discharged 2 days later taking appropriate medications for after PCI and to treat heart failure. Epub 2017 Sep 11. LV Aortic valve Mitral valve Impella 2.5 outlet area Impella 2.5 . The partial thromboplastin time should be monitored every 4 to 8 hours and maintained at about 45 to 55 seconds, unless a higher partial thromboplastin time is required for some other reason. 2022 Feb 28;19(2):115-124. doi: 10.11909/j.issn.1671-5411.2022.02.003. Purge Screen Displays purge system information displayed as a function of time. 2 main types of pumps currently used: Three sequential stents were placed in the area of disease. Hear the stories of patients and explore the latest innovations in Impella technology. You can get a swollen uvula from infections including the flu, mononucleosis, croup, and strep throat. Complications associated with mechanical circulatory support. At P8, the flow rate is 1.9 to 2.6 L/min and the motor is turning at 50000 revolutions per minute. doi: 10.1097/MD.0000000000025159. The patient was weaned from the Impella device, the device was removed in the catheterization laboratory, and the venous and arterial sheaths were secured in place. Regular repositioning of patients and assessment of their skin are necessary to prevent skin breakdown. Impella ventricular support in clinical practice: Collaborative Partner with industry. Comparing traditional intra-aortic balloon therapy with Impella 2.5 percutaneous ventricular assist device, Potential complications of Impella 2.5 support, Nursing care of patients with an Impella 2.5, Impella 2.5 performance level and flow rate, Physician orders for placement of Impella 2.5, Impella competency checklist for nurses in the cardiac intensive care unit: critical elements for managing patients with an Impella 2.5, Brenda McCulloch is a cardiovascular clinical nurse specialist at Sutter Heart and Vascular Institute, Sutter Medical Center, Sacramento, California. Impella use in real-world cardiogenic shock patients: Sobering outcomes. : Simultaneous venoarterial extracorporeal membrane oxygenation and percutaneous left ventricular decompression therapy with, 8. Acute renal dysfunction, Aortic valve injury, Bleeding, Cardiogenic shock, Cerebral vascular accident/Stroke, Death, Hemolysis, Limb ischemia, Myocardial infarction, Renal failure, Thrombocytopenia and Vascular injury In addition to the risks above, there are other WARNINGS and PRECAUTIONS associated with Impella devices. The SVG was aspirated before a distal protection device was placed. Diagnostic cardiac catheterization and coronary angiography performed at the referring facility showed severe triple vessel coronary disease and high-grade lesions in 2 SVGs. He was discharged home 2 days later. If the hemolysis is severe, hemoglobinuria will be seen; if the hemolysis is sustained, acute kidney injury will occur. The cannula portion of the catheter is built with a 30 bend (except for the Impella LD, which has a straight design). That waveform depicts the pressure gradient across the intra- and extraluminal surface of the cannula, and when the device is correctly positioned, the intra- and extraluminal pressures reflect the pressure within LV and aortic root, respectively. The arterial access site must be assessed regularly for bleeding and development of a hematoma. The placement signal will show a normal appearing aortic waveform with systolic and diastolic pressures similar to those shown by the patients arterial catheter. Notably, low native heart pulsatility may similarly trigger either the Impella Position Wrong or the Impella Position Unknown alarm, as the software cannot interpret the dampened amplitude of the placement signal and motor current (Figure 3E). Rolling cart carrying components required to run the Impella 2.5. For more Impella resources, subscribe to our wee. A PFH >40 mg/dL or acute increase in either PFH or LDH suggests increasing hemolysis and warrants intervention.4 The main causes of Impella-related hemolysis are crowding or partial obstruction of the inlet or outlet areas due to poor positioning, thrombus formation in the cannula, operating at the higher range of the power settings, and subtherapeutic anticoagulation. On arrival, his blood pressure was 151/88 mm Hg with a heart rate of 66/min. The patient was brought to the catheterization laboratory and prepared for the procedure. Percutaneous mechanical support devices are placed in a minimally invasive manner and provide life-saving assistance. may email you for journal alerts and information, but is committed Patients must have some level of left ventricular function for an IABP to be effective. Patients in cardiogenic shock supported by venoarterial extracorporeal membrane oxygenation (VA-ECMO) often require an LV unloading strategy to prevent the development of pulmonary edema, thrombus formation in the LV, and reduce LV wall stress.6 The concurrent use of VA-ECMO with the Impella catheter as an unloading strategy (ECPELLA) has become a popular MCS configuration associated with improved cardiogenic shock outcomes over VA-ECMO alone.7 The management of the Impella catheter while in the ECPELLA configuration is no different than described elsewhere in this review. In our case, the Impella had already been confirmed to be in the appropriate position. (NOTE: While the illustrations in this document depict the Impella 2.5 Catheter, the information presented also applies to the Impella 5.0 Catheter and Impella LD Catheter.) The Impella 2.5 catheter (Figure 2) contains a nonpulsatile microaxial continuous flow blood pump (Figure 3) that pulls blood from the left ventricle to the ascending aorta, creating increased forward flow and increased cardiac output. Expert Rev Med Devices. P2 is the lowest performance level that can be used while the distal end of the Impella 2.5 is in the left ventricle. After the device is properly positioned, it is activated and blood is rapidly withdrawn by the microaxial blood pump from the inlet valve in the left ventricle and moved to the aorta via the outlet area, which sits above the aortic valve in the aorta (Figure 8). There are two indications for anticoagulation when using the Impella catheter. She had a history of hypertension complicated by end-stage renal disease and was receiving dialysis treatments 3 times per week. Ann Transl Med. PDF PART 9 IMPELLA TROUBLESHOOTING AND RESUSCITATION - European Society of The most reliable and accurate transthoracic acoustic widow to assess catheter position is the parasternal long-axis window because it will provide a view of the catheter from an orthogonal angle of insonation (Figure 4). The use of inotropic agents and vasopressors was similar in both groups of patients. Like all LV assist devices, the Impella can only pump as much blood as is available to it. Grandchild On Board Car Sign, Suction Cup Baby On Board Sign in - eBay Managing Impella Position Using Imaging - YouTube Our training for staff from the catheterization laboratory consisted of a 3-hour session with didactic and hands-on training. Free shipping for many products! *, *Departments of Cardiology and Critical Care, MedStar Washington Hospital Center, Washington, DC, Department of Medicine, University of California, San Francisco, USA; Division of Cardiology, San Francisco, California, Department of Medicine, MedStar Georgetown University, Washington, DC. The Impella coordinator is present to assist with tubing changes as needed by the nursing staff. : Survey of anticoagulation practices with the, 3. The patient with an Impella 2.5 is at risk of limb ischemia because of the large size of the device. The Suction alarm is triggered when sudden decreases in the placement signal pressure occur in association with lower than expected flows. The use of two Impella devices concurrently has demonstrated decreased LV filling pressures and improved cardiac output for cardiogenic shock patients, although reported data on this use is limited and future studies are required. Some patients on Impella support may be intubated and receiving mechanical ventilation. The symptoms usually last about four to seven days and don't typically require a trip to the healthcare provider, unless it affects an infant or if complications develop. Intravascular ultrasound was performed to confirm optimal stent placement. Conductance catheters were . Catheters with SmartAssist have an upgraded optical pressure sensor that directly measures aortic pressure and uses changes in motor current to infer an estimated LV pressure waveform. The Impella device can be withdrawn, leaving the arterial sheath in place. 29. The placement signal will show depressed cardiac function, evidenced by a damped appearing waveform. 2021 Mar 26;100(12):e25159. The Impella TM Device. Our typical hemodynamic targets are a mean arterial pressure of 6070 mm Hg, a right atrial pressure of 812 mm Hg, a pulmonary arterial wedge pressure <15 mm Hg, and a cardiac index >2.0 L/min/m2.

Hemolysis can be mechanically induced when red blood cells are damaged as they pass through the microaxial pump. Expert Rev Cardiovasc Ther. Advanced Percutaneous Mechanical Circulatory Support Devices for Cardiogenic Shock. Background and aim This study aimed to assess right ventricular (RV) function during cardiogenic shock due to acute left ventricular (LV) failure, including during LV unloading with Impella CP and an added moderate dose of norepinephrine. His estimated ejection fraction was markedly decreased at 20% (normal, 55%70%) on a recent echocardiogram. The Impella 2.5 can also be removed in the surgical setting with direct visualization of the common femoral artery. Pulmonary artery pressures remained elevated after this stent was placed, and the patient was given furosemide and nitroglycerin to decrease preload and increase diuresis. Immediately before removal of the device, decrease the performance level to P0. In this article, I discuss the Impella 2.5, review indications and contraindications for its use, delineate potential complications of the Impella 2.5, and discuss implications for nursing care for patients receiving extended support from an Impella 2.5. A multidisciplinary approach to establishing a program for the Impella is useful in ensuring competency and good outcomes for patients. The Impella 2.5 device is an alternative to an IABP that may be beneficial in some patients who need hemodynamic support. The proximal port of this lumen is yellow. The question that then arises is when to favor escalating inotropes to assist in device weaning. The Impella catheter must be adequately positioned to provide optimal hemodynamic support while minimizing the risk of complications, including hemolysis, interference with the mitral apparatus, suction events, or provocation of ventricular arrhythmias.
