Objective To assess the safety of transeptal puncture(TSP)guided by transthoracic echocardiography(TEE)in percutaneous transcatheter closure of patent foramen ovale(PFO).Methods From March 2022 to December 2022,our department performed TSP guided by TEE in 45 patients with PFO who were unable to pass through the PFO with transcatheter standard technique.After guiding the delivery of the sheath,the foramen ovale was occluded.Results PFO closure with TSP technique guided by transthoracic echocardiography was successfully finished in all the 45 patients,with an operative time of(15.0±3.7)min.No complications such as arrhythmia or cardiac perforation happened immediately and at 12 h after surgery.All the patients recovered and were discharged on the next day after surgery.All the 45 patients were followed up by outpatient echocardiography and dynamic electrocardiogram at 3 months after surgery,and no complications such as intracardiac shunt,pericardial effusion,atrial fibrillation,aortic regurgitation,or arrhythmia were observed.Conclusion TSP guided by TEE is safe and feasible,and it can be used as a supplementary method for complex PFO.
