Pulmonary Vein Isolation

Pulmonary Vein Isolation (PVI) is a medical procedure to treat atrial fibrillation, a common heart rhythm disorder. It involves creating small scars around the pulmonary veins, which carry blood from the lungs to the heart. These scars block abnormal electrical signals that can cause irregular heartbeats. The procedure is typically done using a catheter inserted through a vein, guided to the heart, and then delivers energy—such as heat or cold—to create the scars. PVI aims to restore normal heart rhythm by isolating the faulty signals originating in the pulmonary veins.
