Background:
Right atrial septal pouch is an uncommon septal variant that may predispose to thrombosis. When associated with patent foramen ovale (PFO), it may provide a substrate for paradoxical embolism.
Fih/Early Reports Summary:
A 52-year-old woman with recurrent cryptogenic transient ischemic attacks underwent transesophageal echocardiography showing PFO, a small cribriform secundum defect, and right atrial septal pouch with right-to-left shunt. She underwent fluoroscopy and echocardiography-guided percutaneous direct suture closure. Postprocedural imaging confirmed complete shunt abolition and pouch inversion/collapse, without complications. At 30 days, she remained asymptomatic, with no residual shunt or thrombus.
Discussion:
This case supports the feasibility of suture-mediated PFO closure in complex septal anatomy requiring both shunt closure and pouch exclusion.
Novelty:
This is, to our knowledge, the first reported direct suture closure of PFO associated with right atrial septal pouch.
Take-Home Message:
Direct suture closure may offer a device-free alternative in selected PFO patients with complex anatomy.
