Cardiac Contractility Modulation in Patients With Chronic Heart Failure and the Various Forms of Atrial Fibrillation

The CCM implantation procedure was performed in the right precordial region of the chest (the right subclavian area). Two active fixation Ingevity leads (Boston Scientific) were advanced via the right subclavian vein into the right ventricle (RV) and actively fixed to the right ventricular septum for ventricular sensing and delivery of CCM signals.
