Abstract:
Objective To investigate the preliminary experience of transcatheter closure of patent foramen ovale (PFO) under intracardiac echocardiographic (ICE) guidance and to compare the quantitative ICE data with fluoroscopy. Methods 86 patients with PFO were occluded by cardioSEAL~ under the guidance of ICE. Measurements of baseline PFO tunnel diameter and length were taken by ICE. Balloon stretch diameter (BSD) was measured by both ICE and fluoroscopy. The device deployment was guided and evaluated by 2-D and Color Doppler ICE during and after the procedure, and residual shunt was detected by ICE agitated saline contrast study. Results ICE showed detailed anatomy of PFO and the surrounding structures. The baseline PFO tunnel length and diameter measured by ICE were 11?4 mm (3.6-22 mm) and 4?2 mm (0-9 mm), respectively. BSD of PFO measured by ICE and fluoroscopy were 9.2?2.6 mm (5-16 mm) and 9.7?2.8 mm (5-17 mm), respectively. These BSDs showed excellent correlation (r=0.90, P
