A preexisting ventricular septal defect can provide an alternative pathway for systemic blood flow, preventing hemodynamic compromise in patients with complete prosthetic tricuspid valve obstruction.
Abstract Prosthetic valve thrombosis or obstruction is a feared complication of mechanical valve replacement. The risk is highest in the tricuspid position, with an estimated incidence of 0.7%–1.2% per patient-year, largely attributable to the low-pressure, low-flow environment of the right heart. Clinical presentation is usually acute, with symptoms of right-sided heart failure and cardiogenic shock necessitating urgent intervention. We present an unusual case of a chronic, completely stuck prosthetic tricuspid valve discovered incidentally with no hemodynamic compromise. The patient’s hemodynamic stability was sustained by a preexisting ventricular septal defect, which provided an alternative pathway for systemic blood flow. This case highlights the critical interplay between complex coexisting congenital anomalies in patients with prosthetic mechanical valves.
