Twenty-five-year experience with rastelli repair for transposition of the great arteries.

OBJECTIVE

Our purpose was to describe the outcome of the Rastelli repair in D -transposition of the great arteries and to determine the risk factors associated with unfavorable events.

METHODS

From March 1973 to April 1998, 101 patients with D -transposition of the great arteries and ventricular septal defect underwent a Rastelli type of repair. Median age and weight were 3.1 years (10th to 90th percentiles 0.3-9.9 years) and 12.8 kg (5.9-28.2). Pulmonary stenosis was present in 73 patients and pulmonary atresia in 18; 10 patients had no left ventricular outflow tract obstruction.

RESULTS

There were 7 early deaths (7%) and no operative deaths in the last 7 years of the study. Risk factors for early death, by univariable analysis, included straddling tricuspid valve (P =.04) and longer aortic crossclamping times (P =.04). At a median follow-up of 8.5 years, there were 17 late deaths and 1 patient had undergone heart transplantation. Forty-four patients had reoperations for conduit stenosis, 11 for left ventricular outflow tract obstruction, and 28 had interventional catheterization to relieve conduit stenosis. Nine patients had late arrhythmias, and there were 5 sudden deaths. Overall freedom from death or transplantation (Kaplan-Meier) was 82%, 80%, 68%, and 52% at 5, 10, 15, and 20 years, respectively. Freedom from death or reintervention (catheterization or surgical treatment) was 53%, 24%, and 21% at 5, 10, and 15 years of follow-up, respectively.

CONCLUSIONS

The Rastelli repair can be performed with low early mortality. However, substantial late morbidity and mortality are associated with conduit obstruction, left ventricular outflow tract obstruction, and arrhythmia.
