title: Isolated accessory tricuspid valve causing right ventricular outflow tract obstruction.
abstract: Accessory tricuspid valve (TV) tissue is a rare congenital cardiac anomaly with varying clinical and hemodynamic features. We report a rare case of accessory TV tissue causing severe right ventricular outflow tract obstruction (RVOT) in a patient without associated cardiac anomaly. Surgical resection of the isolated accessory TV tissue resulted in complete relief of the RVOT without compromising TV function.
