The anatomical assessment required in patients undergoing catheter ablation (CA) for ventricular tachycardia (VT) specifi cally aims at study and knowledge of the main structural characteristics of the left/right ventricular chambers, which are expressions of the underlying cardiac disease: these characteristics are strictly related to the arrhythmia and may also strongly condition the approach for CA. The anatomical assessment comprises the evaluation of all vascular structures that may be involved in the catheterization procedure, as well as of the pericardium when a direct percutaneous epicardial approach is undertaken. An accurate diagnostic evaluation must precede each electrophysiological procedure and aims at a complete clinical assessment. The point of our analysis is to fi nalize our diagnostics tools to an effective strategy for ablation and avoid complications. This is of particular relevance today, as CA is used for VT treatment in a wide population of patients with advanced cardiac disease and frequent comorbidities, who may undergo complex procedures of mapping and ablation and require multiple catheterizations.
