[Pre- and postoperative examinations in congential aortic stenoses].
70 patients with congenital aortic stenosis had been operated upon between the age of 7 months and 23 years (average 8 years). For evaluation of the surgical result recatheterization and angiocardiography had been carried out on all patients between 1 and 12 years after operation (mean 7 years). The pre- and postoperative catheter findings, angiocardiograms, ECG, heart-size and clinical findings were analysed and compared with each other. In 2/3 of the cases the operative results could be defined as good or satisfactory. In the last third the operative results had been poor and a reoperation unavoidable. In half of the cases the poor results had been due to a significant residual aortic stenosis and in the other half it was due to massive aortic regurgitation. The prognosis and the indication to operation had been discussed.
