Abstract:
We present the case of a 42-year-old man who underwent tissue mitral valve replacement for symptomatic mitral stenosis. Post-operative course was unremarkable but three-dimensional transoesophageal echocardiography clearly indicated that one cusp had very restricted motion with incomplete opening and premature closure. The cause of this early single cusp failure is unclear. It was not related to flow effects. It is conceivable that cusp failure such as here might contribute towards the degeneration of tissue valve replacements.

TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
