Cardiac Magnetic Resonance Imaging and Multidetector Computed Tomography Scan Illustrating Damus–Kaye–Stansel Operation

Abstract

The Damus–Kaye–Stansel (DKS) operation was first described in 1975 independently by 3 authors, Damus,1 Kaye,2 and Stansel,3 and was soon felt to be an effective method to relieve systemic ventricular outflow–tract obstruction in patients with ventriculoarterial discordance. Since then, the procedure has been applied to patients with several forms of complex congenital heart disease in which systemic outflow is obstructed. The operation consists of an anastomosis of the proximal end of the transected pulmonary artery to the side of the ascending aorta, ensuring unobstructed outflow to the systemic circulation through the pulmonary valve. The pulmonary circulation can be then reestablished by a right ventricle to the distal main pulmonary artery conduit in cases of biventricular repair, or by a Fontan procedure (systemic venous return to the pulmonary artery without the subpulmonary ventricle) in cases in which only a univentricular repair can be offered. We present 2 cases that illustrate the utility of cardiac magnetic resonance imaging and multidetector computed …
