Surgical correction of aneurysms of sinus of Valsalva--a report of 22 cases.

Twenty two cases of aneurysm of sinus of Valsalva managed during a 12 year period are analysed. The right coronary sinus was involved in 14 and the non-coronary sinus in eight cases. It had ruptured in 20 patients while in the other two it had produced right ventricular outflow tract (RVOT) obstruction. Six patients had associated ventricular septal defect (VSD), and eight had aortic regurgitation (AR), five of these requiring aortic valve replacement (AVR). Aortocameral approach was preferred and was used in 18 patients. Recurrence had occurred in one. Surgical management and results are discussed.

Repeat open intracardiac operation--analysis of 55 patients.

Of the 4170 open intracardiac operations performed at our hospital in the last 6 years, 55 (1.3%) were reoperations. Of these failed valve repairs or valve substitutes formed the major group (58%) and the interval between first and second operation ranged from 6 months to 8 years. There were 4 deaths on table and another 6 patients died during their hospital stay giving an early mortality rate of 18 per cent. There was one late death during a follow-up period of 1 month to 3 years. There was no death due to perioperative bleeding complications. We conclude that it should now be possible to perform reoperations with an acceptable mortality and good late functional results.

Tricuspid valve replacement for gross tricuspid insufficiency due to dysplastic valve--a case report.

A case report is presented of a child in whom there was gross tricuspid insufficiency due to marked dysplasia of the tricuspid valve. This patient received prosthetic valve replacement in tricuspid position with excellent post-operative improvement. To the best of our knowledge, this is the first case report of a tricuspid valve replacement for a severely dysplastic tricuspid valve.
