Catheter Ablation
Abbildung 1A-B: Electroanatomical bipolar voltage map of a left ventricle, the coronary sinus (CS) and the middle cardiac vein (MCV) of a patient with nonischemic dilated cardiomyopathy and ventricular tachycardia (VT) is shown in a caudal left posterior oblique projection. Bipolar voltage of < 0.5 mV (suggestive of a dense scar) is depicted in red and the normal myocardium (with bipolar voltage > 1.5 mV) is represented in purple, with other colors corresponding to the intermediate signal amplitude seen in the scar’s border zone. (A) shows a 12-lead of VT 1 and (B) shows a 12-lead ECG of an VT 2 and corresponding pace map, pointed out from origin with white arrows. Dark blue dots indicate phrenicus capture, light blue dots indicate termination of VT during ablation. Red dots indicate ablation points.

Catheter Ablation
Abbildung 2a-d: Kaplan-Meier plot of the time to first VT recurrence after first (a) and last catheter ablation procedures (b); VT free survival (c) and all-cause mortality (d) according to acute results of the catheter ablation procedure; the blue line represents acute complete success of ablation defined as ablation of clinical and all non-clinical inducible ventricular tachycardias. The green line represents the group in which the clinical VT (n = 5) or another non-clinical ventricular tachycardia remained inducible at the end of the ablation procedure. The Log-Rank (Mantel-Cox) test is used to generate p-values.
