Figures

Figure 1
Figure 1
Twelve-lead electrocardiogram (ECG-12) with clinical premature ventricular contractions. ECG-12 showed frequent monomorphic premature ventricular contractions with a QRS morphology suggestive of a superolateral mitral annulus origin.
Figure 2
Figure 2
Earliest activation electrogram and anatomical ablation sites endocardially and from the distal coronary sinus. A: Earliest endocardial activation was found on the ventricular aspect of the mitral annulus in a left anterior oblique view 1-o’clock position, which preceded QRS onset by 19 ms recorded with the radiofrequency (RF) ablation catheter. B: Earliest endocardial activation recorded with the pulsed field electroporation (PFE) delivery catheter preceding QRS onset by 18 ms. C: Earliest activation in the distal coronary sinus, which preceded QRS onset by 29 ms. D: Ablation sites and catheter placement from the endocardial approach. E: The corresponding ablation site in the great cardiac vein – distal coronary sinus. Red tags represent RF ablation sites and blue tags represent PFE delivery sites.

Figure 3
Excitatory response to pulsed field electroporation delivery on 12-lead electrocardiogram (ECG-12). The figure shows the excitatory premature ventricular contraction response to trains of pulsed field electroporation delivery on ECG-12 and, hereafter, sinus rhythm.
