What are the risks of a TAVI procedure?

What are the risks of a TAVI procedure? The procedure itself is relatively safe. The most common risk is vascular injury, so damage to the blood vessel where we advance the tubes and this includes most commonly pain, bleeding or bruising. In some very rare instances you may require a repair of an injured artery or vein where we normally have some help from radiologists or vascular surgeons and all of of these specialists are always available and on standby for this rare eventuality. After your procedure, as long as everything has gone well, you are normally home within 48 hours and you're walking around and hopefully feeling a lot better. Other risks and other complications associated with TAVI include a small risk of stroke, about 1 in 100, a small risk of mortality, again 1 in 100 and a 1 in 10 chance of requiring a permanent pacemaker because where we implant the valve anatomically that's very close to the electrics of the heart and sometimes there is some damage caused that does require a permanent pacemaker to ensure that the heart rate does not drop too low.
