Idiopathic isolated coronary ostial stenosis: a rare lesion with particular clinical and surgical implications.

Isolated coronary ostial stenosis is an unusual condition, most often atherosclerotic in origin. Only few cases have been reported as idiopathic. The clinical profile of the latter patients suggests that this group may represent a distinct clinical entity, with peculiar diagnostic and therapeutic features.

Total anomalous left pulmonary venous connection with intact atrial septum: surgical treatment of a rare case.

Total anomalous left pulmonary venous connection with intact atrial septum is an extremely rare form of congenital heart disease. We describe a case never reported before in which the left pulmonary veins drained directly into the right atrium through a common vein. Surgical correction was successfully obtained by redirecting the blood flow through a newly created atrial septal defect into the left atrium using a gluteraldehyde-treated autologous pericardial patch.
