Abstract
<p>High-resolution 3D mapping has emerged as a strategy to to improve comprehension and treatment of complex cardiac arrhythmias (CCA). A high-density grid-style mapping catheter, with equidistant electrode spacing enabling a number of bipole configurations along and across the splines, was recently introduced to improve substrate mapping and directionality. <strong>Aim:</strong> to analyze procedural data and acute success rates in CCA using a high-density, grid-style catheter. <strong>M</strong><strong>ethods: </strong>Procedure data collected over an initial period of 4 months, in a single center, using a high-density, grid-style mapping cateter (<em>Advisor HD Grid</em>) in patients (P) with CCA. Point collection, mapping/procedure time, radiofrequency (RF) time, fluoroscopy time, complications, and acute outcomes were recorded. <strong>Results:</strong> We studied 12 cases with the following CCA: ventricular tachycardia (VT) in adults with repaired Tetralogy of Fallot (n=4), ischemic VT (n=2), atrial fibrillation (AF, redo and structural heart disease - n=3); atypical atrial flutter (structural heart disease - n=3). The HD Wave configuration was utilized in all cases, collecting an average of 23,372 points (atrial arrhythmias - 21,849, ventricular arrhythmias - 23,976; p=NS). Overall mapping and procedure times were 60±44 and 192±59 minutes (min), respectively. VT ablation was performed endocardial in the right ventricle (3 cases) and left ventricle (2 cases). In VT P the ablation consisted in modification of the arrhythmogenic substrate, targeting scar dechanneling, areas of slow conduction, late potentials, regions of pace-match, mid-diastolic potentials, and early activation. At the end of the procedure, P had no inducibility of the clinical VT. In atrial flutter P, voltage and activation maps were obtained, the arrhythmia was interrupted during ablation, and not inducible. In AF P, all pulmonary veins were successfully isolated (in one redo case, reconduction gaps were identified and eliminated). There were no procedure complications. RF and fluoroscopy times were 24±10 min and 12±9 min, respectively. <strong>Conclusions:</strong> Initial experience with this innovative high-density mapping catheter resulted in a very large number of points collection, both in the atria and ventricles, that resulted in a high rate of acute success, with acceptable mapping and procedure duration, and no complications.</p>
