大動脈弁閉鎖不全症に対するカテーテル的弁輪下大動脈血管形成術の革新的な二重被覆ステント接続法：症例報告

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.
