Abstract:
Objective To explore the practical value of intracardiac echocardiography (ICE) on transcatheter closure of patent foramen ovale (PFO). Methods Eight-six patients with PFO were occluded using CardioSEAL under guidance of ICE. A diagnostic ICE was performed for imaging PFO anatomy and monitoring the closure procedure. Measurements of PFO tunnel diameter and length were made by ICE. The device deployment was evaluated by 2-D and color Doppler ICE after release, and then any residual shunt was detected by ICE agitated saline contrast study. Results ICE showed detailed anatomy of PFO and variations in morphology such as redundant secundum septum, convex secundum septum, tissue extension of primum into the fossa ovalis and hypertrophic limbus. Of 86 cases, 85 cases had successful implantation of the CardioSEAL, 1 case failed.Conclusions Transcatheter closure of PFO guided by ICE is a safe, effective, simple and less invasive solution.
