In five patients (aged 5 to 11 years) with atrioventricular discordance,
pulmonary stenosis or atresia, and origin of the aorta from the right
ventricle, transaortic closure of the ventricular septal defect was
performed. Double-outlet right ventricle was confirmed in four patients.
All patients underwent placement of an extracardiac valved conduit from the
anatomic left ventricle to the pulmonary artery. Neither operative death
nor postoperative complete heart block resulted. Postoperative follow-up
periods were from 3 months to 4 years (average 35 months), and one patient
who had no evidence of complete heart block died suddenly 2 years
postoperatively. Aortic regurgitation developed in two patients from
possible trauma during the operation: Regurgitation was mild (causing
symptoms) in one patient who had had poor surgical exposure with a
subpulmonic ventricular septal defect and a well-developed subaortic conus;
it was trivial (asymptomatic) in the other patient. Transaortic ventricular
septal defect closure, suturing a patch on the anatomic left ventricular
side in patients with atrioventricular discordance and double-outlet right
ventricle or similar anomalies, might help to avoid postoperative complete
heart block if the aorta is large and the subaortic conus is not well
developed.
