Right inferior vena cava connects to the right atrium.

The symptoms of right inferior vena cava connecting to left-sided atrium are usually not apparent until the condition is advanced. Symptoms may include shortness of breath, fatigue, chest pain, palpitations, and swelling of the legs and feet. In some cases, the condition can cause heart failure.

Right inferior vena cava connecting to left-sided atrium is a rare congenital heart defect known as a partial anomalous pulmonary venous return (PAPVR). It is caused by abnormal development of the pulmonary veins during fetal development. It can be caused by genetic factors, environmental factors, or a combination of both.

The most common treatment for a right inferior vena cava connecting to left-sided atrium is a procedure called an atrial septal defect (ASD) closure. This procedure involves closing the hole in the atrial septum with a device such as a patch or a plug. This procedure is usually done using a catheter-based approach, which means that the device is inserted through a vein in the leg and guided to the heart. The device is then deployed to close the hole. In some cases, open-heart surgery may be necessary to close the hole. Other treatments may include medications to reduce the risk of blood clots, and lifestyle changes such as quitting smoking and exercising regularly.

1. Congenital heart defects
2. Abnormalities in the development of the heart
3. Abnormalities in the development of the great vessels
4. Abnormalities in the development of the pulmonary veins
5. Abnormalities in the development of the aorta
6. Abnormalities in the development of the inferior vena cava
7. Abnormalities in the development of the superior vena cava
8. Abnormalities in the development of the coronary sinus
9. Abnormalities in the development of the atrial septum
10. Abnormalities in the development of the tricuspid valve

No, there is no cure or medication for this condition. It is a congenital heart defect that requires surgical intervention to correct.
