Which patients is TAVI suitable for?

TAVI stands for transcatheter aortic valve implantation, a minimally invasive catheter-based procedure for patients with aortic stenosis. Aortic stenosis is a heart defect characterised by the narrowing of the aortic valve, which can cause chest pain (angina), dizziness, palpitations, breathlessness and loss of consciousness. Cardiologist Dr Michael Mullen tells us all about TAVI, the possible risks faced with the operation and the road to recovery.
