Suture connection of overlapping covered CP stents for transcatheter treatment of sinus venosus atrial septal defect with anomalous pulmonary venous connection

Transcatheter correction of a superior sinus venosus defect and partial anomalous pulmonary venous connection with covered stents is a feasible alternative to surgical repair in select patients. Commercially available balloon-expandable covered stents may be of inadequate length to treat some patients. This may require multiple stents to be placed, which increases the risk of stent migration or embolization. A modification of this technique utilizing two interdigitating covered stents secured together with sutures is described, allowing for increased stability of a long stent complex. One failed case and a second successful case are presented.
