What is it?
In TAVI (TAVR) a compressed biological valve on a catheter is advanced, usually from the femoral artery, to the narrowed aortic valve and expanded inside the old valve.
Who needs it?
Patients with severe symptomatic aortic stenosis, especially elderly or high-surgical-risk patients; the decision is made by a Heart Team of interventional cardiologist, cardiac surgeon and imaging specialist.
How is it done?
After a detailed CT angiogram to measure the annulus and access vessels, the procedure is usually performed under sedation and local anaesthesia and takes about an hour. A balloon-expandable or self-expanding valve is chosen by anatomy.
Before the procedure
Echocardiography, cardiac and vascular CT, coronary angiography, dental/infection check and kidney assessment.
After & recovery
Many patients go home within 1–3 days and resume daily activities within weeks. Follow-up echo is scheduled.
Risks & safety
Vascular complications, permanent pacemaker need, paravalvular leak and stroke — all reduced by meticulous planning.
Frequently asked questions
How long does a TAVI valve last?
Long-term follow-up data show good durability; regular echo surveillance is performed and valve-in-valve is possible if needed.
Do I need general anaesthesia?
Usually not; sedation and local anaesthesia suffice.
