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. The use of inotropic agents and vasopressors was similar in both groups of patients. The placement monitoring diagram will continuously scroll through 3 different images because it is not able to differentiate the position of the catheter. The Impella 2.5 catheter is placed percutaneously through the common femoral artery and advanced retrograde to the left ventricle over a guidewire. 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 Impella (Abiomed Inc.) is an axial flow pump on a pigtail catheter that is placed across the aortic valve to unload the left ventricle by delivering non-pulsatile blood flow to the ascending aorta. The Impella coordinator is present to assist with tubing changes as needed by the nursing staff. Transthoracic echocardiography showed increased contractility, and the ejection fraction was 40%. Despite these changes, her blood pressure and cardiac rhythm remained stable. The performance level determines the flow rate and the number of revolutions per minute. We provide 1-to-1 staffing for our patients with an Impella 2.5 until they are hemodynamically stable. While the inability to provide anticoagulation is a contraindication, there is ongoing research into nonanticoagulant purge solution alternatives. 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. You may be trying to access this site from a secured browser on the server. Ongoing practice is essential to develop and maintain competency. Abiomed provides strong clinical support as well as excellent print and Web-based educational materials. 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. On arrival, his blood pressure was 151/88 mm Hg with a heart rate of 66/min. Device-related complications occur more frequently with a longer duration of support. Impella Management for the Cardiac Intensivist : ASAIO Journal - LWW 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. For continued use, the purge fluid is heparinized (50 units heparin per milliliter of fluid) and infused via an integrated infusion pump, the Braun Vista infusion pump (Figure 5). 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. Retract the device until diastolic pressures normalizes. 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. If the Impella remains in place for continued support after the PCI, the tubing system is changed to 2 separate systems. Search for Similar Articles 2021 Feb 26;16(2):e0247667. Impella ventricular support in clinical practice: Collaborative 23. Cardiogenic Shock | Hospital Handbook The Impella controller will alarm when it determines that the device may be mispositioned or dysfunctional. 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. Identification of Cardiogenic Shock The use of anticoagulation is required, and bleeding may develop in some patients. With correct positioning and function, the placement signal and motor current are pulsatile, reflecting the dynamic pressure gradient between the aorta and LV, as well as the cyclical variation in energy required to maintain the desired motor speed over the cardiac cycle (Figure 3A). In order for the interrogator to connect with the permanent pacemaker or implantable cardioverter defibrillator, the Impella console must be turned off for a few seconds while the signal is established. All cases are also followed by the cardiac surgeon who oversees our VAD program and a critical care intensivist. Device failure, although not often reported, can occur. 2022 Feb 28;19(2):115-124. doi: 10.11909/j.issn.1671-5411.2022.02.003. Crit Care Nurse 1 February 2011; 31 (1): e1e16. It is a single tubing system that bifurcates and connects to each port of the catheter. The Impella 2.5 is a percutaneously placed partial circulatory assist device that is increasingly being used in high-risk coronary interventional procedures to provide hemodynamic support. Brenda McCulloch is a member of the Abiomed Administrative Advisory Board. Patients with an Impella may go to the cardiovascular operating room for bypass surgery or valve repair/replacement. We developed preprinted orders for physicians to use for patients remaining on support to ensure consistency in care (Table 8). The catheter device was connected to the Impella console and support was initiated. He had severe mitral regurgitation. More blood products were administered to patients treated with the Impella. The Impella 2.5 device is an alternative to an IABP that may be beneficial in some patients who need hemodynamic support. Epub 2020 Dec 28. The second lumen of the Impella 2.5 is flushed with heparinized saline (500 mL normal saline with 1000 units heparin) by using regular (not infusion pump) intravenous tubing. Arterial repair is done at that time, and the incision is covered with a sterile dressing. Diagnostic cardiac catheterization showed severe triple vessel disease as well as severe diffuse distal disease of his left internal mammary artery (LIMA) graft, his only remaining patent graft. Patients must have some level of left ventricular function for an IABP to be effective. %PDF-1.4 % The trials primary end point of hemodynamic improvement was defined as improved cardiac index at 30 minutes after implantation. Regular repositioning of patients and assessment of their skin are necessary to prevent skin breakdown. Please enable it to take advantage of the complete set of features! 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. Coordination with the perfusionist is essential when patients are being placed on cardiopulmonary bypass. Highlight selected keywords in the article text. Int J Heart Fail. Low purge pressures require immediate intervention by a critical care nurse. The pharmacy prepares the heparinized 20% glucose purge solution and sends it to the unit before our standard change time of 3 pm daily. In our facility, we have a trained CICU nurse managing the Impella while the patient is in the cardiovascular operating room. The proximal port of this lumen is yellow. Function keys that are used with the Impella 2.5 include the P-PERF, MENU, SIGNAL, SCALE, and the ON keys. 6, 7 However, the device may migrate out of . If you have a swollen uvula, you may also be experiencing a sore throat, trouble swallowing, and maybe even a fever. Accessibility The MedStar Washington Hospital Center institutional review board approved the electronic medical record extraction and publication of this data. Rolling cart carrying components required to run the Impella 2.5. 0000000636 00000 n 2017 Nov;45(11):1922-1929. doi: 10.1097/CCM.0000000000002676. To date, we have placed an Impella 2.5 in about 40 patients. Perioperative Management of Patients Receiving Short-term Mechanical Adequate blood flow was reestablished after the intracoronary administration of 500 g nitroglycerin. doi: 10.1097/MD.0000000000025159. Percutaneous mechanical support devices are placed in a minimally invasive manner and provide life-saving assistance. Support with Impella versus intra-aortic balloon pump in acute myocardial infarction complicated by cardiogenic shock: A protocol for systematic review and meta-analysis. Troubleshooting tips. In our facility, this role is filled by the interventional cardiology clinical nurse specialist. Correspondence: Alexander Papolos, MD, Departments of Cardiology and Critical Care, MedStar Washington Hospital Center, 110 Irving St., NW, Rm A127, Washington, DC, 20010. $L"$ For rapid weaning, the performance level is decreased by 1 or 2 levels every 5 to 15 minutes until the pump is set at P2. Assign a point person who can oversee and coordinate the program. The https:// ensures that you are connecting to the The Impella (Abiomed Inc.) is an axial flow pump on a pigtail catheter that is placed across the aortic valve to unload the left ventricle by delivering non-pulsatile blood flow to the ascending aorta. The entire LV placement signal waveform shifts downward. His estimated ejection fraction was markedly decreased at 20% (normal, 55%70%) on a recent echocardiogram. 2. position is wrong. At follow-up 12 months later, the patient remained symptom-free with a normal ejection fraction of 55%. The Impella MCS system is a relatively new technology that has become widely used for the treatment of cardiogenic shock in medical and surgical cardiac intensive care units. This arrangement ensured that new purge fluid was ready when needed and that the nurses had more staffing resources to assist with the tubing change. When the activated clotting time was higher than 250 seconds, the Impella 2.5 was advanced into position via the left common femoral artery and placed across the aortic valve into the left ventricle. 0000004641 00000 n The Impella RP has been authorized only for the duration of the declaration that circumstancesexist justifying the authorization of the emergency use of medical devices under section 564(b)(1) of. official website and that any information you provide is encrypted When hemolysis occurs, hemoglobin level and hematocrit decrease, haptoglobin level decreases, and plasma levels of free hemoglobin increase. 2020 Jul;8(13):835. doi: 10.21037/atm.2020.03.152. The proximal port of this lumen is red. Complications associated with mechanical circulatory support. The Impella coordinator is present for implants to assist the catheterization laboratory staff as needed. Immediately before removal of the device, decrease the performance level to P0. Suction events are mostly due to abnormal device position or insufficient preload. We found performing such changes at a consistent time to be very helpful. Based upon these metrics we make changes to the device power level, inopressor dose, afterload reduction regimen, and diuresis goals as indicated to maintain sufficient but not excessive cardiac support while optimizing RV and LV filling pressures. Impella heart pumps (Abiomed) are intravascular microaxial blood pumps that provide temporary MCS during HRPCI or in the treatment of cardiogenic shock. The PCI procedure of the LAD SVG was then started. Image courtesy ABIOMED Inc, Danvers, Massachusetts. (Figure 3F). If Impella malposition is suspected, use echo to look for inlet or outlet obstructions. At P8, the flow rate is 1.9 to 2.6 L/min and the motor is turning at 50000 revolutions per minute. PDF Patient Information for the Impella 2 - Food and Drug Administration An official website of the United States government. The cannula appears as two bright echogenic, parallel lines, sometimes referred to as the railroad tracks, which ends at the inlet area. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). This arrangement allows rapid initial setup of the console so that support can be initiated quickly. 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. Additional torque can be achieved by rotating the red Impella plug (Figure 5) at the proximal end of the catheter in the desired direction. 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. The Impella should not be used in patients with a heavily calcified aortic valve. Bivalirudin was administered for anticoagulation, and the Impella 2.5 was advanced into position in the left femoral artery. Ventricular Assist Device (VAD) LITFL CCC Equipment If the device advances too far and both the inflow and outflow areas are fully in the left ventricle, the pump position wrong alarm will occur. She was treated with fibrinolytic therapy but continued to have chest pain. trailer <<4E9C4E69F2794E779C95DF45DA44CC4E>]/Prev 560917/XRefStm 1133>> startxref 0 %%EOF 613 0 obj <>stream The VAD coordinators also provide valuable assistance. Using the LV Waveform to Troubleshoot Suction Events - Heart Recovery Transthoracic echocardiography should be used to visualize the device. It is used for high-risk percutaneous coronary intervention and CS. Following this trial, the Impella 2.5 device received its 510(k) approval from the Food and Drug Administration. The .gov means its official. The use of continuous cardiac output monitoring may be useful for patients with cardiogenic shock. 2 main types of pumps currently used: your express consent. It is important to recognize that adjustments from the vascular access site are not necessarily transmitted to the cannula in a 1:1 fashion due to slack and/or torque that may exist or be introduced into the catheter.
