Abstract
Transcatheter closure of secundum atrial septal defect (ASD) has been widely performed as a less invasive alternative to surgery with zero mortality so far in Japan. In the US and Europe, intracardiac echocardiography (ICE) has replaced transesophageal echocardiography (TEE) as a primary imaging tool during percutaneous ASD closure. However, the experience of ICE in ASD closure is limited in Japan. Consecutive 51 patients underwent percutaneous ASD closure with ICE guidance. Clinical results were compared to those of 41 patients who underwent ASD closure with TEE guidance. Pediatric patients and patients with multiple ASDs who were expected to need multiple devices were excluded. Success rate was similar in both groups (ICE 96.1 %, TEE 92.7 %). Catheterization laboratory time was significantly shortened with ICE than with TEE (131 vs. 155 min, p = 0.0003). There were no complications related to the use of ICE. ICE-guided ASD closure is feasible in most adult patients. ICE is superior to TEE in shortening catheterization laboratory time and eliminating general anesthesia, and can potentially replace TEE as the primary image guide during percutaneous ASD closure.
