In medical terminology, different degrees of heart valve leakage (regurgitation) exist. However, when a clinically significant leakage is present, body tissues may not receive adequate blood flow, which can lead to a drop in blood pressure. Furthermore, blood that cannot be pumped forward accumulates in the heart chambers, causing an increase in volume. This volume increase stretches and enlarges the heart muscle over time, negatively impacting the heart's pumping ability (systolic and diastolic function). Consequently, this condition sets the stage for the development of heart failure. This is a typical mechanism of heart failure arising from heart valve diseases.
