Abstract

Objective To investigate the clinical efficacy of intracardiac echocardiography （ICE） guidance in transcatheter closure of latent patent foramen ovale（PFO） among divers. Methods From Jan 2023 to Nov 2024， 36 young divers with PFO， who only had right-to-left shunt during Valsalva maneuver on right heart contrast echocardiography， were enrolled from No. 971 Hospital of the PLA Navy. They were divided into ICE group and transthoracic echocardiography （TTE） group based on intraoperative imaging. Clinical data including baseline characteristics， echocardiographic findings， complications， procedure time， and radiation dose were recorded. Results All 36 patients （19 in TTE group and 17 in ICE group） had 100% immediate closure success rate. No vascular complications， postoperative pericardial effusion， device displacement or embolism occurred. ICE could guide wire passage through foramen ovale， significantly reducing total procedure time， fluoroscopy time， and radiation dose （P < 0.05）. Conclusion ICE enables precise closure of potent PFO in divers and decreases fluoroscopy time and radiation dose， showing significant clinical value.
