Meta analysis of transcatheter closure of atrial septal defect/patent
foramen ovale guided by intracardiac echocardiography and
transesophageal echocardiography
Abstract
Background.Data on the effectiveness and safety of percutaneous
transcatheter closure of atrial septal defect(ASD) and patent foramen
ovale(PFO) guided by intracardiac ultrasound(ICE) are limited. We
conducted a meta-analysis comparing intracardiac ultrasound with
transesophageal ultrasound(TEE) guided surgery. Mehood.From 1996 to
2020, a systematic search was conducted using multiple databases, and
the results were operation time, fluoroscopy time, success rate,
complications, and occluder size. Results.7 studies were included, with
a total sample size of 971 patients, of which 448 patients were treated
with atrial defect occlusion guided by ICE, and the other 523 patients
were treated with atrial septal occlusion guided by TEE. There was a
statistical difference in the fluoroscopy time and procedure time
between the ICE group and the TEE group, (P<0.01), There was
no significant difference in success rate, complication between ICE and
TEE groups (successrate, P=0.71; complications, P=0.51). Conclusion.
success rate, complications and occluder size were similar between ICE
group and the TEE group. Fluoroscopy time, procedure time were
significantly reduced for transcatheter closure of atrial septal defect
guided by intracardiac ultrasound.
