Patients and methods
The study group comprised all 50 adult patients (18 years and older) who underwent surgery for partial AVSD at the TCCCA between 1976 and 1996. This 20-year period was selected both to reflect a reasonably contemporary surgical approach and to allow a minimum follow-up time of 6 months. Thirty-nine of these patients underwent primary repair for symptoms or a substantial left-to-right shunt. The remaining 11 patients had previous AVSD repair in childhood, and required reoperation as adults for
Results
The overall profile of the 50 patients enrolled in the study is shown in Table 1. Diagnoses additional to partial AVSD are listed in Table 2.
Comment
In agreement with recent reports by Bergin and associates [10] and Burke and colleagues [11], perioperative mortality and morbidity in our series of 50 adults undergoing operation for partial AVSD is low. Although the feasibility and safety of surgical repair are now well established, controversy continues to exist as to the optimal management of the adult with an ASD. Partial AVSDs share the same hemodynamic burden of chronic right heart volume overload with secundum ASDs, allowing for certain
