In tricuspid valve regurgitation, a leaky valve can lead to poor heart function.

The tricuspid valves job is to allow blood flowing into the heart from the body to flow to the right ventricle where it's pumped to the lungs for oxygen. If the tricuspid valve is leaky, blood can flow backwards, causing the heart to pump harder. Over time, the heart becomes enlarged and functions poorly.
