The human heart is an engineering marvel, a tireless pump that beats approximately 100,000 times a day to circulate life-sustaining blood. At the center of this intricate operation are four delicate yet resilient structures: the heart valves. When these valves function perfectly, they ensure blood flows in the right direction at the right time. Guided by the expertise of world-class surgeons like Dr. Udgeath Dhir, Principal Director of Cardiothoracic Vascular Surgery at Fortis Memorial Research Institute (FMRI), Gurgaon, this procedure has transitioned from a high-risk gamble to a precision-based solution that restores quality of life. But who exactly needs this intervention? How do you know if your heart is calling for help, and what does the path to recovery look like? Dive through this comprehensive news article to explore the symptoms, diagnosis, and risk factors associated with heart valve replacement. Understanding the Heart’s Healthkeepers To understand valve replacement, one must first understand the valves themselves. The heart has four: the Mitral, Tricuspid, Pulmonary, and Aortic valves. They act as one-way gates, opening to let blood through and snapping shut to prevent it from leaking backward. When a valve fails, it usually falls into one of two categories: Stenosis: The valve becomes stiff or narrow, forcing the heart to work harder to pump blood through a smaller opening. Regurgitation: The valve doesn't close tightly, allowing blood to leak backward (often called a "leaky valve"). In either scenario, the heart is under immense strain. Over time, this leads to heart failure, arrhythmias, or sudden …
