Transcatheter Closure of Superior Sinus Venosus Atrial Septal Defect With Covered Stent Using a Suture-Assisted Deployment Technique

Surgical repair has been the standard therapy for superior sinusvenosus atrial septal defect with associated anomalous pulmonary venous drainage. Transcatheter closure using covered stents has been introduced more recently as a less invasive alternative, but early experience demonstrated significant risks, particularly related to the inability to control precise stent positioning and the danger of migration or pulmonary venous obstruction. A novel suture-assisted deployment technique has been proposed to overcome these limitations.
