Current status and future trends of left ventricular decompression strategies in veno-arterial extracorporeal membrane oxygenation

Abstract

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is a great weapon to save patients with acute heart failure. At present, in most cases, VA-ECMO is perfused through femoral artery intubation, and the external blood flow is opposite to the direction of cardiac ejection, which will increase the left ventricular afterload and lead to left ventricular expansion, which is not conducive to the recovery of cardiac function. This paper reviews the development course of left ventricular decompression at home and abroad, summarizes the present situation of left ventricular decompression technology at home and abroad, analysis of left ventricular decompression technology advantages and existing problems, and put forward their own opinions, to analyze the prevention and solution of left ventricular distension in VA-ECMO, may explore better method, improve the success rate of treatment in patients with heart failure.
