Percutaneous left ventricular assist devices during cardiogenic shock and high-risk percutaneous coronary interventions

Abstract

Left ventricular assist devices were developed to support the function of a failing left ventricle. Owing to recent technological improvements, ventricular assist devices can be placed by percutaneous implantation techniques, which offer the advantage of fast implantation in the setting of acute left ventricular failure. This article reviews the growing evidence supporting the clinical use of left ventricular assist devices. Specifically, we discuss the use of left ventricular assist devices in patients with cardiogenic shock, in patients with acute ST-elevation myocardial infarction without shock, and during high-risk percutaneous coronary interventions.

Treatment of Ventricular Tachycardia in Patients with Heart Failure

“…The Impella inflow catheter is placed into the left ventricle, retrogradely across the aortic valve, with the pump outlet and motor positioned in the aorta. The Impella 2.5 can provide up to 2.5 L/min forward flow into the systemic circulation [36].…”

Ventricular Tachycardia in the Era of Ventricular Assist Devices

“…The TandemHeart provides circulatory support via a left atrial‐to‐femoral artery bypass system. This system consists of a left atrial inflow cannula, an extracorporeal centrifugal pump, a femoral outflow cannula that extends into the iliac artery, and a microprocessor‐based pump controller, and can provide blood flow at rates up to 4 L/min 9 . The Impella device is a catheter‐mounted microaxial rotary pump that is retrogradely placed across the aortic valve into the left ventricle (LV) with the pump outlet and motor positioned in the aorta.…”
