Abstract

Endo-epicardial mapping and radiofrequency catheter ablation of the ventricular arrhythmia of the left ventricle anterobasal zone (summit)

Highlights

  • Ventricular arrhythmias (VA) arising from left ventricular summit can be effectively cured with radiofrequency catheter ablation (RFCA) using different approach by opposite ablation technique

  • В нашем исследовании мы механической травмы или воздействия радиочастотной также отметили увеличение этих показателей и энергии на клапан, и эмболические события (тромбом эпикардиальная радиочастотной аблации (РЧА) из зоны ДБВС была одной из или воздухом), что можно избежать при внимательном составляющих в элиминации эктопии

Summary

Results

Left ventricular summit arrhythmias were successfully mapped and eliminated in 4 pts using combined opposite approach from distal great cardiac vein and left coronary cusp or endocardium of anterobasal region opposite of left ventricular summit. In some clinical cases point of effective RFCA of VA didn’t show optimal activation and pace mapping parameters. In spite of different VA morphology in consecutive patients - left bundle branch block (BBB) or right BBB, pseudo delta waves >54 ms, intrinsicoid deflection time >74 ms and maximal deflection index >0,45 indicated left ventricular summit VA. During one-month follow-up patients did not experience VA recurrence
