Complications

If tricuspid valve regurgitation lasts, it can lead to:

• Heart failure. In severe tricuspid valve regurgitation, pressure can rise in your right ventricle due to blood flowing backward into the right atrium and less blood flowing forward through the right ventricle and into the lungs. Your right ventricle can expand and weaken over time, leading to heart failure.
• Atrial fibrillation. Some people with severe tricuspid valve regurgitation also may have a common heart rhythm disorder called atrial fibrillation.
