The forearm muscles and tendons become damaged from repeating the same motion over and over again.

Tricuspid valve regurgitation, also known as tricuspid valve insufficiency, occurs when the valve does not close properly, causing some blood to flow backward into the heart's right upper chamber (atrium) and increasing the amount of blood there. This impairs the heart's ability to pump the necessary amount of blood to the rest of the body.


Trigger finger is a painful “snapping” condition that can affect your fingers or thumbs when your hand is open or closed. Known medically as stenosing tenosynovitis, trigger finger is a repetitive motion disorder that results from repeated motions of regular daily activities. This condition causes fingers or thumbs (digits) to catch or lock in a bent position. Trigger finger often stems from inflammation of the tendons that connect the muscles of the forearm to your finger and thumb bones and let you bend and extend your digits.


Truncus arteriosus is a rare congenital (present at birth) heart disease where a baby is born with a large hole between the two ventricles (ventricular septal defect) . The hole allows oxygenated blood to mix with blood that is low in oxygen. Some of this mixed blood goes to the lungs, and some goes to the rest of the body. Usually, more blood goes to the lungs. Over time, the blood vessels are permanently damaged and it becomes harder for the heart to pump blood to the lungs, resulting in pulmonary hypertension.


Tubal cancer, also known as fallopian tube cancer, is a rare form of cancer starting in the fallopian tubes.
