How to construct a monocusp valve.

Abstract

Construction of a monocusp is an easy procedure that adds little, if any time to routine transannular patching of the right ventricular outflow tract. It also adds little cost to the operation when constructed from autologous pericardium. The monocusp's utility in preventing or lessening the impact of pulmonary regurgitation in the early postoperative period has been demonstrated. Its utility as a long-term pulmonary valve substitute will need to await longer-term clinical follow-up currently underway at our institution and others.
