Background and Objectives:Phased-array intracardiac echocardiography (ICE) is a novel method for monitoringintracardiac procedures. We report our initial experience with ICE for guiding transcatheter device closure ofatrial septal defects (ASD). Subjects and Methods:From April 2004 to March 2005, ICE was performed in 27consecutive patients during percutaneous device closure of ASDs. The procedural feasibility, the procedure time,the fluoroscopic time, and the complication rate were compared with 27 prior cases that had utilized transesophagealechocardiography. Results:The procedure was performed successfully in all patients. The total procedure time(PT), device deployment time (DT), and fluoroscopic time (FT) were 65.7±22.3, 30.4±23.8, and 12.1±6.4minutes for the study group, and 73.6±23.7, 29.8±16.1, and 11.9±6.0 for the control group, respectively, withno significant difference between the groups. However, PT and DT were significantly shorter in the later 14 casesof the study group compared to the 13 initial cases (52.1±10.9 and 13.2±4.2 vs. 80.3±22.4 and 48.8±22.2, p<0.01, respectively). These differences were also significant compared to the control group, suggesting that there wasa learning curve for the procedure. Conclusion:ICE is a feasible and relatively safe method for monitoring andguiding percutaneous transcatheter closure of ASDs, but a learning period can be expected to achieve better proficiency.(Korean Circulation J 2006;36:612-616)
