211 When Aortic Stenosis Reveals a Surprise: Incidental Aortic Valve hemangioma- A case Report

Introduction/Objective Hemangiomas of cardiac valves are exceptionally rare. To the best of our knowledge, there are only two cases of aortic valve hemangioma in literature. We describe a case of incidental hemangioma of aortic valve in a late forties man with calcified aortic valve stenosis. Methods/Case Report This patient with history of coronary artery disease presented with exertional dyspnea, chest discomfort and dizziness. Echocardiography showed reduced systolic function with ejection fraction of 40% and dobutamine stress test showed low-flow-low gradient state of aortic valve with severe aortic stenosis. Percutaneous coronary intervention had no significant improvement. The patient finally underwent surgical aortic valve replacement. Intraoperative gross examination showed hypertrophied heart with heavily calcified aortic valve extending to the mitral valve. Histopathological examination revealed calcified valvular tissue with foci of subendocardial acute inflammation and focal closely packed, angiomatous proliferation of thin-walled capillary channels lined by bland endothelial cells consistent with hemangioma. Results NA Conclusion Hemangioma of aortic valve is rare, often asymptomatic, and found incidentally. However, it can lead to serious heart problems if interferes with valve function, so we should consider them while diagnosing valvular lesions of the heart. Our case was an incidental finding.
