View larger version (33K): [in a new window]   Figure 1 Proportion of arrhythmias that indicated trans-septal catheterization in the survey for the year 2003. AF = atrial fibrillation; APA = accessory pathway-mediated arrhythmias; AT, Afl = left atrial tachycardia/atrial flutter; AVNRT = atrioventricular node re-entrant tachycardia; VT = ventricular tachycardia.

Eleven centers used no tool, whereas five centers routinely used multiple tools. ICE = intracardiac echocardiography; TEE = transesophageal echocardiography.
