Atrial Fibrillation (AF) is a common heart rhythm disorder where the upper chambers of the heart (atria) beat irregularly and often too fast. This erratic electrical activity can lead to palpitations, shortness of breath, dizziness, fatigue, and significantly increases the risk of complications such as stroke and heart failure. For many patients, medications alone may not control symptoms effectively or may cause unwanted side effects. That’s where ablation — specifically catheter ablation — becomes a vital, often life-changing, option. What Is AF Ablation / Pulmonary Vein Isolation (PVI) The most widely accepted and effective form of Atrial Fibrillation ablation is Pulmonary Vein Isolation (PVI). This approach is based on a well-established understanding: in most AF patients, erratic electrical signals originate from the Pulmonary Veins — the veins that return oxygenated blood from the lungs to the heart’s left atrium. During PVI, an electrophysiologist uses thin, flexi...
