AVNRT, atrioventricular nodal re-entrant tachycardia; AVRT, atrioventricular re-entrant tachycardia; BSA, body surface area; CHD, congenital heart disease; EAT, ectopic atrial tachycardia; IART, intra-atrial re-entrant tachycardia; ICE, intracardiac echocardiography; PVCs/VT, premature ventricular complexes/ventricular tachycardia.
a≥1 arrhythmia mechanisms were present in five cases.
bTrans-baffle approach included Fontan and intracardiac baffles in biventricular palliations.
cTransseptal needle entry into pericardial space during first transseptal attempt (without ICE). One case with atrial flutter that degenerated into ventricular fibrillation arrest, requiring compressions; not related to ICE usage.
