Transcatheter Aortic Valve Replacement (TAVR) is the latest milestone in the field of interventional cardiology.
Transcatheter Aortic Valve Replacement (TAVR) is the latest milestone in the field of interventional cardiology. It refers to transcatheter aortic valve implantation/replacement, which is a procedure where aortic valve is replaced with a biological valve without open-heart surgery. It increases the survival of the patients.
TAVI is presently used in patients who are at high risk or intermediate risk for open heart surgery. It is a biological valve and has shown similar results as open heart surgery in various trials. For further details please use this contact form.
There are many valves which are in the pipeline of development. Two valves that are widely used are Sapien valve and Corevalve. Sapien valve is a balloon expandable valve made of bovine pericardium and sewn inside a metallic stent. Corevalve is a self-expanding valve made of porcine pericardium sewn inside a nitinol frame.
90% of the valves are inserted via the femoral(groin) approach. This allows early ambulation and discharge. The other approaches are trans aortic, trans axillary, trans apical.
MitraClip is a catheter-based procedure (non-surgical) to treat leaky mitral valve otherwise called mitral regurgitation.
It clips the leaky segment of the valve and approximates them when the valve closes, thereby treating the leak. For further details, contact us.
It is a safe procedure when done at a center of excellence and by an expert. The procedure is done from the femoral(groin) vein. The chances of bleeding are minimal.
Successful implantation of MitraClip reduces the leak. It improves the symptoms dramatically and decreases recurrent hospitalization.
MitraClip is widely used in Europe for functional mitral regurgitation. It improves patient symptoms and heart function.
What Is Paravalvular Leak?
Paravalvular leak refers to a leak following surgical aortic valve replacement. It is a leak from the side of the new valve due to suture breakdown. For further details, contact us.
What Are Symptoms Of Paravalvular Leak?
If a patient’s symptoms do not improve following open heart valve surgery, then one should suspect a paravalvular leak. It can present as congestive heart failure or hemolytic anemia due to breakdown of blood cells. It is also a nidus for infection.
What Test Is Required For Its Diagnosis?
2-D Echo, Transesophageal echocardiogram(TEE) and CT scan help in diagnosing paravalvular leaks.
Is Repeat Surgery A Treatment Option?
Yes. Repeat surgery is a treatment option, especially when the leak is very big. It happens when more than 40% of the circumference is dehisced. However, repeat surgery carries high morbidity, mortality and recurrence rate of approximately 30%.
What Is Non-Surgical Treatment Of Paravalvular Leak Closure?
Paravalvular leaks can be closed using plugs by catheter (without open heart surgery). It is a safe procedure and success rate is more than 90%. It is done in a cardiac catheterization lab. For further details please use this contact form.
