Replacement of the common atrioventricular valve with floating annuloplasty in a patient with univentricular physiology.

Significant common atrioventricular valve insufficiency is associated with increased mortality and morbidity in patients with univentricular physiology. Shortly after bidirectional cavopulmonary anastomosis and concomitant valvuloplasty, valve replacement was carried out using a floating annuloplasty technique reinforced by a Dacron strip in a patient with common atrioventricular valve insufficiency. The technique applied is described in detail.
