Case Reports[A case report of epicardial cryoablation in a five-month-old infant with WPW syndrome].
A five month old boy was referred to us with recurrent episodes of tachycardia and heart failure due to WPW syndrome. ECG and electrophysiological studies revealed a left lateral wall accessory conduction pathway. ⋯ Tachyarrhythmia and delta wave disappeared immediately following the operation and the patient had uneventful postoperative recovery. In this paper, the usefulness of epicardial cryoablation with left lateral thoracotomy for infants with a proved left accessory conduction pathway is stressed.

Case Reports[Ruptured aneurysms of sinus of Valsalva with bicuspid aortic valve--a case report of an aged patient (72 years old)].
A 72-year-old man with ruptured aneurysms of the sinus of Valsalva and a bicuspid aortic valve was operated. Ruptured aneurysms were found in the noncoronary sinus region, and they were opened to the commissure between the anterior cusp and septal cusp of the tricuspid valve. ⋯ Ruptured aneurysm of Valsalva is very rare in a aged patient. In this case, it is considered that the bicuspid aortic valve associated with malformations of the aortic cusp caused a weakness of the sinus wall, and this region gradually became aneurysmal.
