Transcatheter Aortic Valve Replacement Surgery (TAVI)

The Third China International Structural Heart Disease Conference

Wednesday 9th October 2019

Professor Jan Kovac, an interventional cardiologist at Glenfield Hospital in Leicester, will present a live Transcatheter Aortic Valve Replacement surgery (TAVI) on the 9th of October. As part of the International Structural Heart Disease conference.

In previous years, an audience of 150,000 people have tuned in to watch these live procedures. The Third China Structural Heart Disease Conference 2019 brings together clinicians from across the world through an online platform that demonstrates new techniques and innovations for educational and knowledge sharing purposes. The conference broadcasts 65 operations from 34 heart centres across the world to countries in Asia, Europe and North America. A multitude of expert clinicians perform procedures on variety of different heart problems on a patient in their clinics which is broadcasted out.

TAVI is usually an alternative option for patients who may be at high risk for open heart surgery. It is a less invasive procedure than open heart-valve surgery. The damaged heart valve would be replaced using a heart valve made of natural tissue obtained from the heart of a pig or cow. The new valve is delivered via catheter, thereby avoiding open heart-valve surgery. The procedure resembles a balloon angioplasty, in which a catheter - a long, flexible tube - is threaded through an artery and a balloon device on the end inflates to help open up a narrowing in an artery in the heart. Special imaging equipment is used to guide position and placement of the new valve. In the case of TAVI, the replacement valve collapses to a very small diameter and is crimped onto the balloon device.

The surgeon positions the replacement valve inside the patient's natural aortic valve and inflates the balloon. This causes the replacement valve to expand, pushing the faulty valve aside. The replacement valve begins to function as soon as the balloon catheter deflates to permit the flow of blood. The catheterization procedure typically takes 1 to 2 hours, and patients are up and walking within 24-48 hours after the procedure. The typical hospital stay is 3 to 5 days.
