Transesophageal echocardiography (TEE) is invaluable in identifying the exact mechanism of prosthetic valve dysfunction (PVD), which may help in the proper management of patient. Here, we report a case of severe mitral regurgitation due to flail mitral valve leaflet resulting from torn bioprosthetic cusp where TEE was instrumental in demonstrating the exact mechanism of valve dysfunction.
