As the heart engages in its ceaseless rhythm of contraction and relaxation, the atrioventricular valves, in a perfectly coordinated dance, quickly swing open. This allows a flood of blood to fill the ventricles during the phase of diastole, ensuring an unbroken link between the heart's dual roles of filling and pumping. As this occurs, the semilunar valves demonstrate their crucial function by closing firmly, forming a secure barrier that prevents any backward flow of blood into the ventricles. This complex interplay of precise mechanical functions, as Richard Zelman MD has illustrated in his work, is foundational to the cardiovascular system's overall performance. This ballet of blood flow regulation is not without its challenges. Disorders affecting the heart valves can disrupt the harmony of this intricate dance, leading to conditions such as stenosis or regurgitation. Stenosis, characterized by the narrowing of valve openings, impedes the smooth flow of blood, imposing ...
