Does intracardiac echocardiography (ICE)-guided transcatheter closure provide safe and effective midterm outcomes in adults with interatrial shunts?
P
Population
140 adults (mean age 43, 70% female) referred for catheter-based closure of interatrial shunts, followed for a mean of 36.6 months.
E
Exposure
Intracardiac echocardiography (ICE)-guided transcatheter closure of interatrial shunts.
O
Outcome
Immediate success rates, predischarge occlusion rates, complication rates, fluoroscopy and procedural times, radiological exposure, midterm complication rates, and midterm occlusion rates.safety
ICE-guided transcatheter closure of interatrial shunts is safe and effective, yielding a 96.5% midterm occlusion rate while avoiding complications like device oversizing, aortic erosion, and device thrombosis.
Cite This Study
Rigatelli et al. (2009) conducted a cohort in Interatrial shunts (patent foramen ovale, atrial septal defect) (n=140). Intracardiac echocardiography (ICE)-assisted transcatheter closure was evaluated on Midterm follow-up occlusion rate. ICE-guided transcatheter closure of interatrial shunts achieved a 99% procedural success rate and a 96.5% midterm occlusion rate at 36.6 months, with no aortic erosion or device thrombosis.
