ABSTRACT

Background:

The Lecompte procedure for transposition of the great arteries has an advantage because it obviates the need for an extracardiac conduit for the reconstruction of the pulmonary outflow tract. We evaluated the effectiveness and the application of the Lecompte procedure. Material and

Method:

A retrospective review was conducted of the records of 46 patients who underwent the Lecompte procedure during the past 15 years. Mean age at operation was 29.2+/-20.3 (range 3~83) months. The diagnoses involved anomalies of the ventriculoarterial connection with ventricular septal defect and pulmonary outflow tract obstruction, such as transposition of the great arteries, double-outlet right ventricle, and double-outlet left ventricle.

Result:

Early mortality was 4.4% (2 of 46 patients) and late mortality was 6.8% (3 of 44). The mean follow-up was 11.2+/-6.9 years. Eighteen patients (43.9% of survivors, n=41) had pulmonary stenosis (pressure gradient above 30 mmHg), the main reason for which was a calcified monocusp valve (n=15, 83.3%). Seventeen of 46 patients (37.0%) underwent reoperation 15 for pulmonary stenosis, 5 for residual ventricular septal defect, 4 for left ventricular outflow tract obstruction, 3 for pulmonary insufficiency, and 4 for other causes. The cumulative survival rates were 91.3+/-4.2%, and 87.0+/-5.8% at 10 and 15 years, respectively. The actuarial probabilities of freedom from reoperation for pulmonary stenosis were 90.6+/-4.5%, 73.9+/-7.3%, and 54.0+/-10.4% at 5, 10, and 15 years, respectively.

Conclusion:

The Lecompte procedure is an effective treatment modality. Repair in early age is possible with acceptable morbidity and mortality, but recurrent right ventricular outflow tract obstruction caused by degeneration of the monocusp valve is a problem that needs resolution.
