India, Oct. 10 -- Breathlessness, fatigue, dizziness, difficulty climbing stairs or a sudden decline in exercise capacity are often dismissed as signs of ageing. But sometimes, they may point to a problem with one of the heart's four valves-the structures that ensure blood flows in the right direction. When a valve becomes narrowed, leaky or fails to function properly, the heart has to work harder. Over time, this can worsen symptoms, reduce quality of life and, in severe cases, contribute to heart failure. The good news is that heart valve treatment has changed significantly. What once required major open-heart surgery can, for appropriately selected patients, now be treated through catheter-based procedures that avoid opening the chest. Among the important advances are MitraClip, TAVR and TMVR. MitraClip: Repairing a leaky mitral valve The mitral valve controls blood flow between the chambers on the left side of the heart. When it does not close properly, blood leaks backwards, causing Mitral Regurgitation (MR). MitraClip provides a minimally invasive way to reduce this leakage. A small clip is guided through a catheter inserted into a blood vessel and positioned on the mitral valve to help it close more effectively. By reducing the leak, the procedure can decrease the strain on the heart and improve symptoms such as breathlessness and fatigue. For appropriately selected patients, it can offer symptom relief and better functional capacity without conventional open-heart surgery. TAVR: Replacing a narrowed aortic valve Aortic stenosis, or narrowing of the aortic valve, makes it harder for blood to leave the heart and reach the rest of the body. TAVR (Transcatheter Aortic Valve Replacement) has transformed treatment for many patients with severe aortic stenosis. A replacement valve is delivered through a catheter, commonly through an artery in the groin, and positioned inside the diseased valve. Unlike conventional valve replacement surgery, TAVR does not require a large chest incision or opening of the breastbone, offering a less invasive treatment option for suitable patients. TMVR: A new option for complex mitral valve disease Sometimes, a diseased mitral valve cannot be repaired effectively, particularly when the anatomy is complex or the patient faces significant surgical risk. TMVR (Transcatheter Mitral Valve Replacement) involves placing a new replacement valve inside the heart rather than repairing the existing one. It may be considered for carefully selected patients, including some who have previously undergone mitral valve surgery or may face high risks with another open-heart operation. Advanced imaging, detailed anatomical assessment and an experienced heart team are essential in deciding whether these procedures are appropriate. It's about the right treatment for the right patient Modern valve care is no longer simply about asking, "Can we operate?" The more important question is: "What is the safest and most effective treatment for this patient?" A multidisciplinary heart team including interventional cardiologists, cardiac surgeons, imaging specialists and other experts evaluates the valve, heart, overall health and anatomy before recommending treatment. Persistent breathlessness, unexplained fatigue, dizziness, chest discomfort or difficulty doing activities that were once easy should not be ignored. Sometimes, the reason behind a shrinking life is a diseased heart valve. And with the right diagnosis and treatment, patients may have an opportunity to regain their independence, improve their quality of life and return to living more fully.
