Change in biventricular function after cone reconstruction of Ebstein's anomaly: an echocardiographic study

The Cone reconstruction in Ebstein's anomaly (EA) aims to reduce tricuspid valve regurgitation (TR) and reposition the valve to the anatomic annulus, but post-operative progress of ventricular function is poorly understood. This study evaluated biventricular function after Cone reconstruction using echocardiographic techniques. A retrospective study assessing longitudinal change was conducted from 2009 to 2014. All symptomatic patients with EA and severe TR undergoing surgery were included. Transthoracic advanced echocardiography was performed pre- and post-operatively (at short-term (
