Long-Term Results of Congenital Aortic Stenosis Treatment in the Era of Percutaneous Balloon Valvuloplasty: Up to 33 Years Follow-Up.

Background The goal of this study was to evaluate long-term results of percutaneous balloon valvuloplasty (BVPL) used exclusively for initial management of congenital aortic stenosis in children. Methods and Results A total of 409 consecutive pediatric patients (134 newborns, 275 older patients) who underwent BVPL as initial treatment of aortic stenosis in a single nationwide pediatric center were subjected to a retrospective follow-up study. The resulting follow-up time reached a median of 18.

Influence of fenestration on long-term Fontan survival.

Introduction: Fenestration in the total cavopulmonary connection system may improve the outcome of patients with significant risk factors for Fontan haemodynamics. Our study aims to analyse the difference in long-term survival between non-fenestrated and fenestrated patients.

Methods: All consecutive patients (n = 351) who underwent total cavopulmonary connection between 1992 and 2016 were identified.

Long-term results after correction of persistent truncus arteriosus in 83 patients.

Objective: This study aims to analyse long-term results after correction of truncus arteriosus in all patients operated in one institution over 28 years.

Methods: Between 1981 and 2009, 83 patients, median age 54 days, underwent repair of truncus arteriosus. Interrupted aortic arch was present in 14 (17%), severe truncal valve insufficiency in 10 (12%) and non-confluent pulmonary arteries in five (6%) patients.
