Dehiscence of a pulmonary bioprosthesis with a focal dissection of the pulmonary artery in a patient with congenital pulmonic stenosis

Pulmonary valve replacement ( PVR ) is the most common adult congenital cardiac operation performed. Valve degeneration leading to prosthetic stenosis and/or regurgitation is a long‐term risk in this population and may be associated with paravalvular leak ( PVL ). Complications involving the proximal pulmonary artery, including dissection, are less clearly defined. Herein, we report the case of a 30‐year‐old patient with a history of multiple pulmonary valve interventions secondary to congenital pulmonic stenosis, who developed dehiscence of a bioprosthetic PVR associated with significant paravalvular leak ( PVL ) and further complicated by a focal dissection of the proximal pulmonary artery.
