Cor triatriatum dexter is a rare congenital heart defect in which the right atrium of the heart is divided into two chambers by a membrane. This membrane can block the flow of blood from the right atrium to the right ventricle, leading to a variety of symptoms, including shortness of breath, fatigue, and heart palpitations. Treatment typically involves surgical removal of the membrane.

The most common symptom of Cor triatriatum dexter is shortness of breath, which is usually caused by a buildup of fluid in the lungs. Other symptoms may include fatigue, chest pain, palpitations, and difficulty breathing during exercise. In some cases, the condition may cause heart failure or arrhythmias.

Cor triatriatum dexter is a rare congenital heart defect in which the right atrium is divided into two chambers by a membrane. The exact cause of this condition is unknown, but it is believed to be due to abnormal development of the heart during fetal development. Possible causes may include genetic mutations, environmental factors, or a combination of both.

The primary treatment for Cor triatriatum dexter is surgical repair. This involves opening the membrane and connecting the two atria. In some cases, a patch may be used to cover the opening. In some cases, a catheter-based procedure may be used to open the membrane. In some cases, medications may be used to reduce the pressure in the atrium and improve blood flow.

The risk factors for Cor triatriatum dexter include:

1. Congenital heart defects
2. Family history of congenital heart defects
3. Premature birth
4. Low birth weight
5. Chromosomal abnormalities
6. Maternal diabetes
7. Maternal drug use during pregnancy
8. Maternal smoking during pregnancy
9. Maternal alcohol use during pregnancy
10. Maternal exposure to certain medications during pregnancy

At this time, there is no cure for Cor triatriatum dexter. Treatment typically involves medications to reduce the pressure in the affected chamber of the heart, as well as surgery to repair the defect. Medications may include diuretics, ACE inhibitors, beta blockers, and calcium channel blockers. Surgery may involve patching the membrane or removing it completely.
