Covered Stent Correction for Sinus Venosus Atrial Septal Defects, an Emerging Alternative to Surgical Repair: Results of an International Registry
Authors' conclusion
Cardiopulmonary bypass was avoided in the majority of patients, and major complications were infrequent.
Study context
- Population
- Patients undergoing covered stent correction for sinus venosus atrial septal defect (SVASD)54 units · 12 years
- Participants
- 381 patients
- Outcome
- Successful correction without major complications or additional catheter interventions
Methodological detailsmulticentre, retrospective audit, 10-zig covered Cheatham Platinum stent in 62%, 90% of procedures in the past 5 years, Balloon-expandable stents (8 types) in the majority; self-expanding stents (4 types) in 4.5%
