Cardiac troponin I release after transcatheter closure of atrial septal defects is associated with supraventricular arrhythmias on early follow-up.

Elevation of postprocedural transient cardiac biomarkers and exacerbation of supraventricular arrhythmias have been reported in the subject literature.
