Cryoballoon Catheter Ablation❄️🫀 In patients with paroxysmal atrial fibrillation, one proven treatment option is isolating the pulmonary veins, the common trigger sites. Cryoballoon ablation does this by delivering cold energy through a balloon catheter to freeze the tissue around the veins, creating durable lesions that block erratic electrical signals. Other ablation techniques include Radiofrequency ablation with heat and, more recently, PFA using electrical energy. Visit https://tca.medical
