How TAVI Transforms Aortic Valve Treatment Without Open Heart Surgery

UPDATE - follow-up to TAVI has ushered in a new age in treating aortic valve diseases: how it works and who it is for: Medical advancements in treating severe aortic valve diseases allow eligible patients to undergo a Transcatheter Aortic Valve Implantation instead of traditional open-heart surgery. The aortic valve sits between the aorta and the main heart ventricle, managing blood flow across the body through its cusps. Over time, calcium deposits create stiffness known as aortic stenosis, a condition common in adults over seventy or those born with a two-cusp valve defect.

The Procedure

During a TAVI procedure, a biological valve made from bovine or porcine tissue inside a metallic frame is placed on a catheter. Doctors typically insert this catheter through the leg artery, guide it to the heart, and deploy the new valve to start working instantly without cutting the chest bone. Patients often receive local anaesthesia with mild sedation, allowing most individuals to discharge within a few days.

Patient Selection

While TAVI has become the preferred choice for most patients over sixty-five with aortic stenosis, it does not suit everyone. Doctors must evaluate age, overall health, valve robustness, and anatomical factors, especially for younger patients or those needing bypass surgery. Because tissue valves typically last ten to twelve years, a dedicated heart team of cardiologists, surgeons, and imaging experts must plan a lifelong valve management strategy.

Context

Severe aortic stenosis causes symptoms like shortness of breath, chest discomfort, and dizziness, and untreated cases can lead to heart failure and sudden cardiac death. Advanced imaging helps medical teams choose the right valve size and intervention path for each unique patient.
