Why the study?
Does transcatheter closure of atrial septal defect increase the risk of conduction abnormalities and arrhythmias in patients undergoing the procedure?
Does transcatheter closure of atrial septal defect increase the risk of conduction abnormalities and arrhythmias in patients undergoing the procedure?
Transcatheter closure of ASD is associated with a transient increase in supraventricular premature beats and early conduction abnormalities, particularly with larger devices and longer procedure times.
May warrant post-procedure arrhythmia monitoring with larger devices; leaves open causal confirmation in randomized trials.
