Percutaneous suture‐mediated transcatheter patent fossa ovalis (PFO) closure has been shown to be an effective and safe technique with self‐evident advantages due to the lack of a permanent device heart implant. The success of this novel technique relies on an optimal catch of the interatrial septa, especially the septum primum which is floppier than the bulkier muscular septum secundum. We hypothesized that double suture of septum primum would further improve the efficacy of the procedure by increasing the surface contact between the septa when the septum primum is bent into the right atrium. We have provided proof of this concept by implementing a modified technique in two patients with PFO and cerebral ischemic events.
