Temporary biventricular support strategies. a Biventricular assist and oxygenation support using two centrifugal pumps. Cannulation details: transfemoral right atrium (RA) drainage → allograft to pulmonary artery (PA) for returning oxygenated blood; and left ventricle (LV) apex drainage to aorta return. An oxygenator was included in the right ventricular assist device circuit. b Biventricular and oxygenation support provided using a single centrifugal pump. Dual drainage cannulas positioned in the LV apically and right atrium transfemorally. Oxygenated blood was returned to the ascending aorta through central cannulation. Insert demonstrates how the two drainage tubes were merged using a Y-connector to enable usage of a single pump
