A 63-year-old man with chest pain at rest was referred to our hospital. Transthoracic echocardiography showed a mobile ball-like mass at the top of the right coronary cusp. Subsequently, transesophageal echocardiography also showed a mobile mass at the right coronary cusp. Aortic valve replacement with a mechanical valve was performed under general anesthesia. We diagnosed this condition as papillary fibroelastoma based upon the pathological findings with hematoxylin and eosin staining, and Elastica van Gieson staining. Coronary angiography revealed no organic lesions. The operation was successful, and the patient remains asymptomatic. We speculate that the resting chest pain was induced by transient occlusion of the right coronary orifice by the tumor. We describe this rare case in detail including a review of the literature.
