Open heart surgery in the first 24 hours of life.

The results of open heart surgery in infants have steadily improved. The performance of corrective surgery very early in life has thereby been encouraged. We report four patients who underwent successful surgical correction within 24 h of birth. Two patients with total anomalous pulmonary venous drainage and one patient with pulmonary atresia and intact septum were corrected with the aid of profound hypothermia by the combined surface and bypass cooling technique. Cardiopulmonary bypass alone was used for the fourth patient with aortic stenosis. The usual surgical techniques can be applied successfully to infants even within 24 h of life.
