TAVI (Transcatheter Aortic Valve Implantation) or TAVR (Transcatheter Aortic Valve Replacement) is a minimally invasive surgical procedure used to treat aortic stenosis, a condition where the aortic valve narrows, restricting blood flow from the heart. 

·       Procedure: TAVI/TAVR involves inserting a catheter through a small incision, typically in the groin, to deliver a new valve to the heart. The new valve is usually collapsed within a balloon and expands once in place.

·       Indications: It is primarily used for patients who are at high risk for open-heart surgery due to age, comorbidities, or other health factors.

·       Benefits: The procedure generally results in less pain, a shorter recovery time, and a reduced risk of complications compared to traditional surgical valve replacement.

·       Risks: Potential risks include bleeding, infection, stroke, and heart rhythm problems.

·       Outcomes: TAVI/TAVR has shown excellent short- and long-term outcomes, significantly improving patients' quality of life and survival rates.

TAVI/TAVR has transformed the management of aortic stenosis, especially in older adults, making it a significant advancement in cardiovascular medicine.
