IPCD-for-consultation.docx
The aortic valve controls the flow of blood out of the lower left chamber of the heart into the main artery (aorta). In aortic valve regurgitation, the aortic valve is unable to close properly and allows blood to leak back into the heart. This can cause fatigue, chest pain and shortness of breath, and may lead to heart failure.
In transcatheter aortic valve implantation (TAVI) a tube (catheter) is inserted into the heart through a large blood vessel, usually in the groin, or directly through the chest wall. A replacement valve is passed through this tube and inserted (implanted) inside the existing faulty valve (the native valve). The aim is to reduce symptoms and prolong life.
