Innovative Double-Covered Stent Connection With Suture Thread for Transcatheter Sinus Venosus Atrial Septal Defect...

Atrial septal defect (ASD) is a common congenital heart condition in adults. We present a case of successful transcatheter closure of a 1.5-cm sinus venosus ASD in a 34-year-old man with exertional dyspnea. Using an innovative technique, two 43-mm XXL covered CVS Optimus stents were sutured together for enhanced support and delivered via the jugular and femoral veins. This dual-stent approach provides advantages over traditional methods, reducing surgical risks and recovery times. However, surgical intervention remains preferred for complex anatomical variations. This case highlights the effectiveness of a novel transcatheter technique for sinus venosus ASD closure.
