An estimated 1.6 million Americans suffer moderate to severe leakage through their heart's tricuspid valve, but what causes the problem is not well understood. A new study found that either dilating the tricuspid valve opening or displacing the papillary muscles that control its operation can cause the valve to leak. A combination of the two actions can increase the severity of the leakage, which is called tricuspid regurgitation.
