Transcatheter Aortic Valve Replacement (TAVR)
What is Transcatheter Aortic Valve Replacement (TAVR)?
Transcatheter Aortic Valve Replacement (TAVR) is a minimally invasive procedure used to treat severe aortic valve stenosis, a condition where the aortic valve becomes stiff and narrowed, restricting blood flow from the heart to the rest of the body. This procedure involves using a catheter to replace a diseased valve with a balloon-like tissue valve to restore normal blood flow.
Why is TAVR Important?
TAVR serves as an alternative to doing open-heart surgery by inserting a thin tube through a blood vessel to restore normal blood flow
Aortic stenosis can cause serious complications like heart failure and even death within 1-2 years if left untreated. TAVR can relieve symptoms like fatigue, chest pain, and heart murmur and prevent the risk of heart failure
Since TAVR is minimally invasive, it allows for quicker recovery and shorter hospital stays
Types of TAVR Approaches:
Transfemoral: Catheter is inserted through the femoral artery in the groin, most common approach
Transapical: A small incision in the chest is made to let to catheter be inserted into the heart’s apex
Transaortic/Subclavian: Catheter is inserted through other arteries if the femoral artery isn’t possible
Types of TAVR Deployment Mechanism:
Balloon-expandable valves: Valves are squeezed onto a balloon catheter and expanded
Self-expanding valves: Valves are designed to expand on their own once the catheter is released
Risks of TAVR:
TAVR is generally safe and used in younger and lower-risk patients, but it can potentially lead to vascular complications: stroke, heart attack, valve leakage, infection, etc.
Even though TAVR is less invasive and has a faster recovery time than a traditional aortic valve replacement, the risk of needing a pacemaker is higher with TAVR
Transcatheter Aortic Valve Replacement (TAVR) exemplifies an advancement in cardiovascular treatments by treating severe aortic stenosis through a minimally invasive procedure. Instead of conducting open-heart surgery, TAVR inserts a catheter through a blood vessel to restore blood flow for patients. Even though TAVR has significant benefits like faster recovery and shorter hospital stays, it may not be suitable for everyone and could cause more complications for certain patients. Consult a medical professional if you have any questions about TAVR.
