Evaluation of the Safety and Efficacy of the CoolCryo System for Cardiac Cryoablation in the Treatment of Atrial Fibrillation in a Single-arm, Non-randomised, Open-label Clinical Trial
The study involves endocardial cryoablation of the left and/or right atrium of the heart using the CoolCryo system as an adjunct to mitral valve surgery, with the aim of eliminating atrial fibrillation (AF), which is a common sequelae of mitral valve defects and is associated with an increased risk of ischaemic stroke, heart failure and death.
• Written consent from the patient to participate in the study.
• age ≥18 years.
• patient qualified for mitral valve surgery (mitral valve plication or mitral valve replacement with or without left atrial appendage closure).
• a documented diagnosis of co-occurrence of paroxysmal or persistent atrial fibrillation (AF) since at least 3 months prior to surgery with exclusion of acute conditions.
