Figures

Figure 1
Figure 1
(a) 12-lead surface ECG recorded on admission showing marked delta waves consistent with an anteroseptal manifest AP (WPW preexcitation) (b) Decreased LV systolic function with an EF of 34.6% (measured with Simpson’s method in an apical four chamber view) (c) M-Mode echocardiography image showing marked dyssynchrony caused by the ventricular preexcitation of the anteroseptal AP and dyssynchrony measurements
Figure 2
Figure 2
(a) Three-dimensional anatomy of the right atrium and ventricle, with blue dots showing targets on the anteroseptal region and diagnostic catheters in the high right atrium (HRA), esophagus (OZFGS), right ventricle (RVA), and the 6 mm cryocatheter active in the middle. (c) Fluoroscopic image in the left 300 oblique position, with the two diagnostic catheters in the esophagus and the RV and the 6 mm cryocatheter in the anteroseptal region. (b and d) Intracardiac and surface 12-lead electrograms recorded during successful cryoablation showing the disappearance of the preexcitation sign in the 4th second of the first cryotest lesion IVC - inferior vena cava, RA - right atrium, RV - right ventricle, SVC - superior vena cava
Figure 3
Figure 3
(a) M-mode echocardiography image in parasternal long-axis view showing improved left ventricular systolic function with an EF of 69%. (b) M-mode echocardiography image in parasternal long-axis view showing improved dyssynchrony measures. (c) 12-lead surface ECG, showing no ventricular preexcitation sign and right bundle branch block after successful ablation of the AP
