This technique is original in that it involves a single site (the ascending aorta) easily accessible to cannulation. Following lateral clamping of the ascending aorta, a bifurcate Dacron prosthesis is anastomosed. The draining cannula is introduced through one of the branches of the prosthesis and manually guided through the aortic sigmoid leaflets down to the left ventricular ejection outlet. The perfusion cannula is introduced through the outer branch of the prosthesis. The end of this cannula is positioned at the origin of the prosthesis to avoid a possible bend in the fork. This technique is a simple and effective means of providing left ventricular support.
