Summary

The aim of the study is to evaluate the impact of cryoablation of atrial fibrillation in patients with severe chronic heart failure (CHF) on long term outcome of CHF and efficacy (endurance) of the procedure itself. The study hypothesis is that cryoablation in eligible patients with CHF and ICD/CRT (implantable cardioverter defibrillator / cardiac resynchronization therapy) implants reduce the number of recurrent CHF hospitalizations, mortality, need for mechanical support of LV (left ventricle) and heart transplant (primary endpoint) at 1 year observation in comparison to traditional (pharmacological) treatment..

PROCEDURE

Cryoablation

After left atrial appendage (LAA) thrombus exclusion, the transseptal puncture will be performed and intravenous heparin will be administered to achieve Activated Clotting Time (ACT) ≥300 seconds.The pulmonary vein (PV) isolation will be performed. Optimal cryoballoon positioning will be confirmed by PVs angiography. Pulmonary veins isolation will be confirmed by entrance/exit block using appropriate catheter. During cryoablation of the right PVs, high-output right phrenic nerve stimulation will be performed using a diagnostic catheter placed in the superior vena cava. Whenever decrease/loss of pacing capture will be observed, cryoablation will be immediately terminated.
