The authors use the Bretschneider's cardioplegic solution at 4°C as myocardial preservation in 45 open-heart cases in infants. Using moderate hypothermia at 28°C, the mean myocardial temperature is 17.2°C; using profound hypothermia at 18°C, the mean myocardial temperature is 11.7°C. The reinfusion criteria is myocardial temperature equal or up to perfusion temperature, that is aout 40 to 50 minutes after the first infusion. The need of heart defibrillation has been 3 cases over 45 (6.5%). In the early post-operative course, they notice 2 low cardiac output syndromes (5%) who responded well at catecholamines infusion. The hospital mortality is 2 deaths out of 45 cases, disappointingly in spite of myocardial protection.
