Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this prospective randomized double-blind study was to compare the efficacy of new pharmaceutical composition containing botulinum toxin injection in epicardial fat pads for preventing recurrences of atrial tachyarrhythmia in patients with paroxysmal atrial fibrillation undergoing coronary artery bypass grafting.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1

All patients underwent conventional CABG surgery. After the main stage of the surgery new pharmaceutical composition containing botulinum toxin (50 U/1 mL) was injected into the entire four visible area of the major epicardial fat pads. First epicardial left atrial fat pad is located anterior to the right superior pulmonary vein and corresponding to the anterior right ganglionated plexi (GP); second epicardial fat pad is located inferoposterior to the right inferior pulmonary vein and corresponding to the inferior right GP; third fat pad is located anterior to the left superior pulmonary vein (PV) and left inferior PV (between the PVs and left atrial appendage (LAA), corresponding to the Marshall tract GP and superior left GP; forth fat pad located inferiorly to the left inferior PV and extends posteriorly and corresponding to the inferior left GP

Group 2

All patients underwent conventional cardiac surgery. After the main stage of the surgery 0.9% normal saline (1 mL at each fat pad) was injected into the entire four visible area of the major epicardial fat pads. First epicardial left atrial fat pad is located anterior to the right superior pulmonary vein and corresponding to the anterior right GP; second epicardial fat pad is located inferoposterior to the right inferior pulmonary vein and corresponding to the inferior right GP; third fat pad is located anterior to the left superior PV and left inferior PV (between the PVs and LAA), corresponding to the Marshall tract GP and superior left GP; forth fat pad located inferiorly to the left inferior PV and extends posteriorly and corresponding to the inferior left GP
