[Heart tumors in newborn infants and infants. Apropos of 5 cases].

Between February 1985 and March 1987, 5 children underwent resection of primary cardiac neoplasms, 3 of them in the first days of life and 2 before the age of 6 months. Routine echocardiographic follow-up of pregnancies allowed detection of cardiac tumors in 2 foetuses 30 and 36 weeks old. In 3 children the diagnosis was suspected by the discovery of cardiac murmur or congestive heart failure. The first case was an hemangioma, originating from outside of the left ventricular wall, which could be resected without cardiopulmonary bypass (CPBP). The other case was a pseudomyxoma, spreading extensively inside the right atrium. The third case was a rhabdomyoma arising from the pulmonary infundibulum with clinical manifestations of tuberous sclerosis. The last two patients had intraseptal lesions, just above the aortic valve; complete resection was therefore impossible, particularly in one patient with multiple tumors. There was one death related to congestive heart failure. The remaining four survivors were followed up for an average of 18.4 months (+/- 12.9) and all were in functional class I. Echocardiographic follow-up showed evidence of a residual subaortic lesion in one asymptomatic patient.
