Rare Case of Mitral Valve and Tricuspid Valve Aneurysm Presented with Progressive Dyspnea

Introduction: Mitral valve aneurysm (MVA) is a saccular, bulging structure of the mitral leaflet that expands during systole and collapses during diastole. Morand provided the first description of the MVA case in 1729. There are no symptoms or indicators particular to an aneurysm in MVA; instead, the clinical findings are comparable to those in mitral regurgitation. Tricuspid valve aneurysms are a bulging or outpouching of the septal leaflet of the tricuspid valve and have been documented in the literature less frequently in association with endocarditis, but as congenital anomaly they have not yet been reported. Case Presentation: We present a case of mitral valve aneurysm and tricuspid aneurysm causing progressive dyspnea. To our knowledge this is the first case of an incidental finding of bilateral atrioventricular valve aneurysm. The patient cardiac findings were limited to mild symptoms and were managed with a medical approach. Conclusion: Atrioventricular aneurysm discovery by accident is infrequent. Shortness of breath and increasing dyspnea may result from this. Only a few cases have been described in the medical literature. In this instance, an unexpected cause of dyspnea in an elderly patient is presented. Keywords: tricuspid valve aneurysm, mitral valve aneurysm, pulmonary hypertension
