Additional left ventricular septal lead facilitates R-wave sensing of implantable cardioverter-defibrillator in arrhythmogenic right ventricular cardiomyopathy: a case report.

ABSTRACT:

Background

Implantable cardioverter-defibrillator (ICD) implantation is a key therapeutic option in arrhythmogenic right ventricular cardiomyopathy (ARVC) to prevent sudden cardiac death due to ventricular tachycardia (VT) and fibrillation (VF). However, sub-optimized R-wave sensing due to myocardium loss interferes with VT/VF identification and appropriate therapy. We tried to implant a 3830 lead to the left ventricular septum (LVS) to facilitate ICD sensing in an ARVC patient.

Case summary

A 68-year-old woman diagnosed with ARVC was scheduled to undergo ICD implantation. Initially, no sites with suitable R-wave amplitudes were found in the right ventricle (RV) to deploy the defibrillation lead (<3.0 mV). It was likely due to severe RV involvement, but the LVS myocardium wa
