Transapical Cannulation With a Dual Lumen Cannula for Mechanical Circulatory Support in Cardiogenic Shock.

Abstract

Temporary mechanical circulatory support can be delivered through a variety of techniques, including percutaneous left ventricular assist devices, surgically implanted rotary pumps, and veno-arterial extracorporeal membrane oxygenation. However, limitations include the effects of high afterload, intravascular hemolysis, patient vascular anatomy, surgical morbidity, and limited patient mobility which can hinder patient recovery. We describe a series of patients managed with transapical left ventricular mechanical circulatory support using a dual lumen cannula for the management of cardiogenic shock as a bridge to recovery or definitive decision. This support strategy may represent an additional option in the care for patients with cardiogenic shock that can provide full temporary anterograde mechanical circulatory support while potentially improving patient mobility and minimizing device-related complications.
