Key result
TandemHeart biatrial cannulation for VA-ECMO enables biventricular unloading in refractory VF with LV thrombus.
Why the study?
VA-ECMO increases LV afterload, promoting LV distension and often requires additional strategies to reduce LV pressure and volume in left heart failure patients.
Case Report (n=1)
Biatrial cannulation using a TandemHeart percutaneous trans-septal cannula for VA-ECMO can be used for biventricular unloading in patients with refractory ventricular fibrillation and LV thrombus.
Supports feasibility of biatrial TandemHeart cannulation for biventricular unloading in VA-ECMO; hypothesis-generating and should not yet change practice.
Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) may improve survival after cardiac arrest by providing cardiopulmonary support. However, VA-ECMO increases left ventricular (LV) afterload, which can promote progressive LV distension and often requires a secondary approach to reduce LV pressure and volume in patients with left heart failure. We report a case of biventricular unloading via biatrial cannulation in the presence of LV thrombus using a TandemHeart percutaneous trans-septal cannula for VA-ECMO in an adult patient with refractory ventricular fibrillation.

Jumean et al. (2014) conducted a case report in Refractory ventricular fibrillation and advanced heart failure (n=1). Biventricular unloading via biatrial cannulation using a TandemHeart percutaneous trans-septal cannula for VA-ECMO was evaluated. Biventricular unloading via biatrial cannulation using a TandemHeart cannula for VA-ECMO was described in an adult patient with refractory ventricular fibrillation and LV thrombus.
