Rastelli Operation for D-Transposition of the Great Arteries,Ventricular Septal Defect,and Pulmonary Stenosis

Abstract

Objectives:

Our preferred approach for the surgical treatment of patients with D-transposition of the great arteries, ventricular septal defect, and pulmonary stenosis has been the Rastelli operation. We herein evaluate our 30-year experience with this procedure.

Methods:

Clinical records for patients who underwent the Rastelli operation between 1988 and 2017 at our institution were retrospectively reviewed. Primary outcomes included freedom from death or cardiac transplantation and freedom from conduit reintervention.

Results:

Forty-seven patients met inclusion criteria. Mean follow-up was 11.7 ± 6.8 years. Forty-three (91.5%) patients received a palliative systemic-to-pulmonary artery shunt and/or atrial septostomy prior to the Rastelli procedure. Five (10.6%) patients required ventricular septal defect enlargement at the time of the Rastelli procedure. The overall mean right ventricle-to-pulmonary artery conduit size was 17.0 mm. Mortalities included one early and three late deaths. Freedom from death or cardiac transplantation was 93% and 84% at 5 and 25 years, respectively. Seven patients required pacemaker placement, two immediately postoperatively and five late. Freedom from conduit replacement was 85% and 25% at 5 and 15 years, respectively. Seven (14.9%) patients required a second conduit intervention. Forty-one (87.2%) patients were New York Heart Association class I or II at the most recent follow-up.

Conclusions:

The Rastelli operation for D-transposition of the great arteries, ventricular septal defect, and pulmonary stenosis offers excellent mid- to long-term survival. The need for conduit replacement remains the most common indication for reintervention, and further study of the optimal choice of conduit will be useful.
