Decompression of Left Ventricle During Venoarterial Extracorporeal Membrane Oxygenation Support as a Step to Transplant

Abstract

Objectives: Left ventricular distention can be recognized during the use of venoarterial extracorporeal membrane oxygenation as a key complication. Left ventricular decompression may decrease pulmonary pressure, minimize ventricular distention, and allow myocardial recovery.

Materials and Methods: We applied venoarterial extracorporeal membrane oxygenation to 4 patients while on a wait list for cardiac transplant.

Results: Two patients with severe heart failure developed high end-diastolic pressures leading to left ventricular distention. We used atrial venting methods to decrease the pressure.

Conclusions: Here, we discussed the strategies to manage ventricular distention by conservative, interventional, and surgical means.
