ABSTRACT
Multiple studies have reported the adverse impact of audible clicks from mechanical heart valves on the quality of life. Sadly, this can become a lifelong liability in younger patients necessitating explantation. Bioprosthetic valve replacement is the treatment for this distressing condition associated with an isolated mechanical valve. However, patients who have undergone a mechanical Bentall's procedure represent a unique surgical challenge. In view of the significant complications associated with a redo aortic root operation, the alternative of a "valve-over-valve" implantation is an attractive option that might present reduced morbidity. We report a unique case of valve noise intolerance in a patient who underwent a bioprosthetic valve-over-valve replacement following previous Bentall's procedure with a mechanical valved conduit.
