ABSTRACT
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.

Polyvinylchloride (PVC) disposable endotracheal suction catheters were successfully used as temporary intravascular shunts in 5 patients of popliteal artery trauma. These simple shunts should be used routinely in such conditions to immediately re-establish blood supply to the ischaemic limb particularly in patients of polytrauma where systemic anticoagulation is contraindicated. This avoids the inherent delay prior to vascular repair and reduces the incidence of irreversible ischemia.

A case of successful surgical repair of tetralogy of Fallot with complete atrioventricular canal in 4 year old female child is reported. Double patch technique and combined right atrial and right ventricular (RV) approach were used to repair this defect. The ventricular patch was tailored wide and redundant anteriorly in the form of a sail to prevent subaortic obstruction. Right ventricular outflow tract obstruction was relieved through an infundibular incision with subsequent use of subannular pericardial patch. The relevant literature on the management of this rare anomaly is briefly reviewed.

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.

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.

A prospective comparative study was undertaken to determine quality of myocardial preservation during open heart surgery by crystalloid and blood cardioplegic solutions. Total 55 consecutive patients were studied. Alternate patients received blood and crystalloid cardioplegia at random. Group I had 30 patients who received crystalloid cardioplegia, and group II, with 25 patients, received blood cardioplegia. The efficacy of two solutions was assessed by serum enzyme estimation of creatinine phosphokinase, M.B. fraction of creatinine phosphokinase and serum glutamate oxalate transferase (CPK, CPK-MB, SGOT), electron microscopic study of Left Ventricular biopsy and clinical assessment of post anoxic cardiac performance. Group II patients had lower serum enzyme levels, lesser microscopic myocardial damage, and better cardiac performance during immediate post-operative period, thus proving superiority of myocardial protection by blood cardioplegia.

Aneurysm of ascending aorta with aortic valve incompetence is a formidable pathological entity having a relentless course. Etiological factors include syphilitic aortitis, dissection of aorta, Marfan's syndrome and similar conditions. With the advance in operative technique and extra corporeal circulation, now it is possible to treat these conditions by surgery. Surgical intervention includes replacement of entire ascending aorta along with aortic valve by an artificial valve conduit. Basically, two procedures are described, namely, the conventional method and Bentall's operation, both involving a great technique challenge. Our experience with both these techniques is being described in four consecutive cases in the last one year.
