Transcatheter correction was performed in 25 patients, with a further 6 awaiting stent implantation. Only 8 patients were deemed technically unsuitable. The procedure involved balloon test inflation in the anticipated stent landing zone with simultaneous transesophageal echocardiography and pulmonary venography to confirm defect closure and unobstructed pulmonary venous drainage, followed by deployment of a 10-zig covered Cheatham platinum stent. Stents of lengths between 5 and 8 cm were implanted. A second, uncovered stent was used for anchoring in 9 patients. The RUPV was protected with a high-pressure balloon during stent implantation to prevent pulmonary venous obstruction in 4 patients. The median follow-up period was 1.4 (interquartile range: 0.8 to 1.7) years, with no mortality. Stent embolization occurred in 1 patient; another required drainage of hemopericardium. Cardiac computed tomography after 3 months confirmed unobstructed pulmonary venous return. At latest follow-up, a residual shunt was present in 1 patient.

Conclusions

Transcatheter correction of SVASD may be considered as an alternative to surgery in a substantial proportion of patients.
