Left atrial appendage ablation using cryoballoon

Isolation of the left atrial appendage (LAA) can improve the outcomeof atrial fibrillation (AF) ablation. The first study pertaining to LAA electrical isolation and concomitant device occlusion to treat persistent AF was published recently. As a result, the study refreshed interest in LAA isolation.1 There are no data available in the literature regarding the safety and efficiency of LAA ablation using cryoballoon. In this paper, we will describe a successful case where LAA ablation using the firstgeneration cryoballoonwas undertaken.
