Risk Stratification and Prevention of Thromboembolism: What Is the Role of Intracardiac Echocardiography?
Pulmonary vein isolation is becoming the treatment of choice for symptomatic atrial fibrillation (AF) that is refractory to drugs [1–3]. However, thromboembolic complications are an important limitation of this approach , occurring in up to 2.8% of the patients. Alternative energy sources such as cryoablation and ultrasound have the potential to improve the safety of the procedure by preventing disruption of the endothelial surface during energy delivery [5,6].
