A 2.5 year old male infant who had a ventricular septal defect and mild pulmonary stenosis was admitted for evaluation of fever and anemic complexion in February 1995. After admission, echo cardiography revealed massive vegetations from the outflow of the right ventricle to the right pulmonary artery through the pulmonary valve, and serial blood cultures were found to be positive for streptococcus mitis. Antibiotics did not relieve the high fever or decrease the volume of vegetation in the patient. At surgery, performed 2 weeks after the admission, the pulmonary valve was entirely destroyed and it was resected without prosthetic replacement after the excision of the vegetation and a Teflon patch was used for VSD closure. The post-operative course produced no noticeable complications. In the follow-up echocardiographic study, no vegetation was observed.

We reported a case of left atrial myxoma with renal infarction as an initial clinical symptom. A 65-year-old man had severe right lumbago. A chest CT demonstrated right renal artery embolism. On emergency operation a right renal embolus was removed. Preoperative echocardiography and transesophageal echo showed a tumor in his left atrium which was close to the mitral valve. The tumor was resected one week after the first operation. Embolectomy of the right renal artery could not restore renal function. To the best of our knowledge, this type of cardiac myxoma with renal infarction as an initial clinical symptom is rare.
