Case in brief
A 14-year-old boy with a superior sinus venosus atrial septal defect and partial anomalous return of the right middle and upper pulmonary veins underwent transcatheter repair with a covered stent. The team used a modified temporary holding-wire technique: a guidewire placed through the stent’s outermost strut was exteriorized via the internal jugular vein to control stent position. An 80-mm covered stent, anchored proximally with a 28-mm bare-metal stent, completely excluded the atrial communication and redirected anomalous venous flow to the left atrium without obstruction.
What made this case unusual
The modification replaced the temporary suture with an exteriorized guidewire threaded through the stent’s outermost strut, allowing stent control and fluoroscopic visualization during deployment.
Diagnostic / clinical pearl
In transcatheter repair of superior sinus venosus defects, temporary control of the covered stent’s position is a key technical challenge; this case describes a guidewire-based holding method that provided grip and fluoroscopic visibility.
Why it matters
The authors suggest this simple modification may improve procedural control and safety and broaden the applicability of transcatheter repair.
