Midterm results after ventricular septation for double-inlet left ventricle in early infancy

We performed ventricular septation for a 40-day-old boy with double-inlet left ventricle and discordant ventriculoarterial connection but without pulmonary stenosis. Postoperative cardiac function is satisfactory, with no evidence of pulmonary hypertension or subaortic stenosis. Nine years after the operation, the patient has an active life, is free from symptoms, and requires no medication. He may be the first patient to survive ventricular septation for double-inlet left ventricle in early infancy.
