Congenital anomalies of the coronary artery are rare. However, they can cause sudden death because of arrhythmia. We present a case of a 62-year-old man with severe aortic valve regurgitation associated with an anomalous origin of a narrowed right coronary artery (IB₂ according to the Shirani Classification) detected on preoperative coronary three-dimensional computed tomography (CT) . The patient underwent both aortic valve replacement for aortic regurgitation, and coronary artery bypass. The postoperative course was uneventful.

We report a rare case of a protruding tumor from the right atrial free wall into the cardiac sac. A cardiac tumor was incidentally detected in the right atrium of a 64-year-old man by transthoracic echocardiography. The tumor was located in the right atrial anterior free wall, infiltrating the right artrial appendage near the tricuspid valve annulus. It had an irregular surface, did not have a tumor stalk, and was considerably mobile. We resected the tumor and performed cryosurgical ablation of the remnant tissue to reduce the risk of local recurrence. Histopathologic examination confirmed the tumor to be metastatic malignant fibrous histiocytoma (MFH). The postoperative course was uneventful, and the patient was discharged 11 days after surgery. Follow-up computed tomographic scans and transthoracic echocardiography did not reveal any evidence of local cardiac recurrence or distant metastasis.
