Transcatheter Patent Foramen Ovale Closure Guided Only by Transesophageal Echocardiography Without fluoroscopy

Abstract

Background Standby of transesophageal echocardiography (TEE) is necessary for any PFO closure in case of some cases with complicated anatomy of patent foramen ovale (PFO). The safety and effectiveness of Transcatheter PFO closure guided only by TEE navigation without fluoroscopy is unclear.Methods From 2017.06 to 2019.11, we included 38 patients who were recommended for PFO closure by the department of neurology at our hospital. The procedure was performed in a regular operating room by TEE navigation without fluoroscopy. Follow-up was given at 1st month, 3rd month, 6th month, 1st year and 2nd year after operation for each patient.Results All 38 patients were successfully performed PFO-closure guided by TEE. Procedural and intrahospital survival was 100%. Survival after a mean follow-up of 17.1±1.6months was 100%. "Catheter in sheath” technique was adopted in 16 cases. After the procedure, all 28 migraines with aura alleviated at different degree. All 10 patients suffering from pre-operational cryptogenic stroke survived and showed no evidence for recurrence of stroke (fatal or non-fatal), peripheral embolism or transient ischemic attack during follow-up. No serious adverse events in the PFO closure procedure and during the follow-up period.Conclusion First clinical experiences showed that percutaneous TEE guided PFO closure is safe and effective and might be promoted.
