Transcatheter Aortic Valve Implantation (TAVI), also referred to as percutaneous aortic valve replacement, is a minimally invasive procedure to treat severe symptomatic aortic stenosis. Aortic stenosis is a condition where the heart’s aortic valve becomes narrowed or obstructed, preventing it from opening properly and blocking the flow of blood from the left lower chamber of the heart to the aorta. In the early stages, patients with severe aortic stenosis may have no symptoms. However, as the disease progresses, classical symptomatic of breathlessness on exertion, chest pain and syncope heralds a more sinister prognosis.In a TAVI procedure, the diseased aortic valve is replaced to restore normal blood flow.
