Closed cardiovascular surgery in the first year of life--experience with 40 consecutive cases.

A review of 40 consecutive infants with cardiovascular lesions requiring surgical intervention, without the use of the heart-lung machine, during a 3 year period is presented. Twenty-one patients were cyanotic and 19 were non-cyanotic preoperatively. In the former group, an operation was performed on an urgent or emergency basis in 8 patients (38%). In the latter group, 12 patients (63%) were in congestive heart failure and needed digitalis and diuretics preoperatively. The most frequent lesions among both groups were TOF and aortic coarctation, each being encountered in 6 patients, to be followed by d-TGA, PDA, and vascular ring, each being observed in 5 patients. The youngest patient was 8 hours old, had ectopia cordis associated with omphalocele, and the oldest was 12 months old, had a vascular ring. The lightest infant weighed 1.6 kg and had ligation of PDA at the age of one month. The most common surgical procedure was a systemic pulmonary artery shunt (13 patients), closure of PDA (5 patients), followed by repair of aortic coarctation using the LSA as a patch (6 patients), and division of vascular ring (5 patients). The operative M.R. was 15% in the whole series, 19% among the 21 cyanotic babies, 11% among the 19 non-cyanotic infants and 40% among the 10 patients operated in the first month of life. No death was noted among the 14 patients operated after the age of 6 months. Late mortality occurred in 4 patients giving a total mortality rate of 38% in this group of 21 infants with cyanotic malformations.(ABSTRACT TRUNCATED AT 250 WORDS)
