Right heart assist during beating bypass for severe left ventricular dysfunction.
Three patients with triple-vessel disease and severe left ventricular dysfunction underwent successful revascularization on a beating heart, using a right ventricular assist system. Heparin-coated circuits with a centrifugal pump provided 2.5 to 3.5 L x min(-1) of flow to maintain good hemodynamics and enable easy access to the posterior vessels during vertical displacement of the heart.
