Transthoracic echocardiography should be used to visualize the device. Detailed view of distal end of Impella 2.5. Expert Rev Cardiovasc Ther. IABP therapy has been in use since the late 1960s and has been widely used in clinical practice since that time. Slow weaning is accomplished by decreasing the performance level by 1 or 2 levels every 2 or 3 hours. On arrival, his blood pressure was 105/66 mm Hg with a heart rate of 64/min. 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. In these situations, one must weigh the risk of time-dependent device-related complications with inotrope-related increases in myocardial oxygen demands. Context 1. . E-mail: [emailprotected]; Twitter: @AlexPapolos. None of the patients had hemodynamic instability develop during the procedure. 2022 Jan;19(1):1-10. doi: 10.1080/17434440.2022.2015323. We have also placed the Impella 5.0 in 3 patients. The proximal port of this lumen is red. Patients who undergo high-risk percutaneous coronary intervention (PCI), such as procedures on friable saphenous vein grafts or the left main coronary artery, may have an intra-aortic balloon catheter placed if they require hemodynamic support during the procedure. When the heart displays a question mark over it with the words "Impella Position Wrong": 1. controller can't determine catheter position. For this reason, we recommend a conservative approach to catheter manipulation with a the enemy of good is perfect philosophy. Highlight selected keywords in the article text. 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. 0000004020 00000 n Heparin 9000 units was administered intravenously for anticoagulation, and the Impella 2.5 was advanced into position in the left femoral artery. She was transferred to the CICU and supportive medical therapy was initiated. The Impella TM Device. 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. Cardiogenic shock; Impella; Mechanical support devices; intra-aortic balloon pump; mechanical circulatory support; percutaneous ventricular assist device. In the Impella LD, 5.0, and RP, the placement signal is a differential pressure waveform that is measured from the differential pressure sensor. The optimal depth for the Impella 2.5, CP, 5.0, and LD is 3 cm to the beginning of the inlet area, and readjustment should be considered if the depth is more than 0.5 cm from this target. The device also cannot be used in patients with severe peripheral arterial disease because of the large sheath size required for its placement, nor can it be used in patients who cannot tolerate anticoagulation with heparin. Our training for staff from the catheterization laboratory consisted of a 3-hour session with didactic and hands-on training. your express consent. 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.
