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

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.
