Insights
Surgical repair of aortopulmonary window in infants demonstrated excellent long-term outcomes. This study highlights successful surgical interventions for this congenital heart defect, ensuring survivors remain in excellent functional class.
Area of Science:
- Pediatric Cardiac Surgery
- Congenital Heart Disease
Background:
- Aortopulmonary window is a rare congenital heart defect requiring surgical correction.
- Understanding the different types and surgical approaches is crucial for successful outcomes.
Purpose of the Study:
- To review the surgical management and long-term outcomes of infants with aortopulmonary window.
- To evaluate the effectiveness of different surgical techniques for aortopulmonary window repair.
Main Methods:
- Retrospective analysis of 11 consecutive infant patients operated on between 1975 and 1986.
- Surgical techniques included patch closure, ligation, and division/suture, utilizing cardiopulmonary bypass.
- Various surgical approaches were employed: transaortic, transpulmonary, and transwindow.
Main Results:
- Six patients had classic aortopulmonary window, 4 had ductus type, and 1 had a complex variant.
- A single operative death occurred, with all survivors achieving New York Heart Association Functional Class I.
- Mean follow-up was 6.5 years, demonstrating sustained excellent functional status.
Conclusions:
- Surgical repair of aortopulmonary window in infants yields excellent long-term functional results.
- Timely surgical intervention is critical for managing this congenital heart anomaly.
- Successful outcomes are achievable with various surgical techniques and approaches.
Abstract:
From June, 1975, through April, 1986, 11 consecutive infants with aortopulmonary window were operated on at the Department of Cardiac Surgery, Ospedali Riuniti, Bergamo, Italy. The classic type of aortopulmonary window was present in 6 patients, whereas 4 patients had a ductus type of aortopulmonary window and 1 patient had a double aortopulmonary window, associated transposition of the great arteries, and ventricular septal defect. Operative technique included patch closure of the defect by means of cardiopulmonary bypass using various approaches: transaortic in 3, transpulmonary in 2, and transwindow in 2. The aortopulmonary window was ligated in 3 patients, in 2 of whom an incorrect diagnosis of patent ductus arteriosus was made at cardiac catheterization. Division and suture of the defect through a median sternotomy was performed in the remaining patient, who was moribund on admission. There was a single operative death. All survivors are in New York Heart Association Functional Class I at a mean interval of 6 1/2 years postoperatively.
