Pulmonary vein isolation (PVI)
This procedure is a treatment for atrial fibrillation (AF). AF can lead to symptoms of breathlessness, palpitations, dizzy turns, fatigue and in severe cases can weaken the heart muscle.
People with AF have a higher risk of stroke because blood can stagnate in pockets of the atria instead of being pumped through normally, and form blood clots which can cause a stroke.
The goals of treatment for AF include regaining a normal heart rhythm (sinus rhythm), controlling the heart rate, reducing symptoms, and reducing the risk of blood clots and stroke.
Should the first PVI ablation not be successful long term and AF returns it may be possible to repeat the procedure.
