Transcatheter Aortic Valve Implantation (TAVI)* is a minimally invasive procedure to replace a diseased aortic valve, often used for severe aortic stenosis (narrowing of the valve). Unlike open-heart surgery, TAVI uses a catheter inserted through a small incision, typically in the leg, to guide and implant a replacement valve.
Key features:
– Conditions treated: Severe aortic stenosis causing symptoms like chest pain, fatigue, or shortness of breath.
– Components: A collapsible artificial valve delivered via a thin tube (catheter).
– Procedure: Done under local or general anesthesia, often with shorter recovery (1–3 days in hospital vs. weeks for surgery).
TAVI is especially beneficial for high-risk patients or older adults who may not tolerate traditional surgery. It improves blood flow, reduces symptoms, and enhances quality of life. Risks are generally low but can include bleeding or stroke. A heart team will assess eligibility based on imaging, health status, and individual needs.
