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

Catheter Cardiovasc Interv. 2022 Sep;100(3):399-403. doi: 10.1002/ccd.30303. Epub 2022 Jul 12.


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.

Keywords: covered stent; superior sinus venosus defect; suturing; technique modification.
