2. Figure 1
A: Resting 12-lead electrocardiogram shows sinus rhythm with preexcitation on the left and orthodromic tachycardia on the right. B: Image of the noninvasively obtained isopotential biventricular epicardial electrocardiomap of preexictation in sinus rhythm. The site that depolarizes first on the biventricular epicardium is depicted in yellow. The virtual unipolar electrogram from the local site (red dot) shows rS morphology consistent with the endo-epi spread of preexcitation. The scale on the left of panel B color codes the virtual electrogram potential (in millivolts), with yellow representing the most negative value and deep green representing the most positive value. MA = mitral annulus; NCC = noncoronary cusp; PDA = posterior descending artery; RCC = right coronary cusp; RVOT = right ventricular outflow tract; TA = tricuspid annulus.

3. Figure 2
Intracardiac electrograms are recorded from the His bundle area (A), the earliest site on the right atrioventricular (AV) annulus (B), and the site of successful ablation below the junction of the right- and noncoronary aortic cusps (C). The first beat in panel C shows fusion of local A and V. In the next beat, they separate following the disappearance of the preexcitation during ongoing ablation.

A: Aortic root (top) and right coronary (bottom) angiogram in the LAO view. B: Aortic root (top) and right coronary (bottom) angiogram in the RAO view. The ablation catheter is located at the successful site. Two quadripolar catheters are inserted to record His and coronary sinus electrograms, respectively. C: A 12-lead electrocardiogram at the time of elimination of preexcitation during subaortic ablation at the junction of the right- and noncoronary cusp. CS = coronary sinus; LAO = left anterior oblique; LCC = left coronary cusp; NCC = noncoronary cusp; RAO = right anterior oblique; RCC = right coronary cusp; RF = radiofrequency.
