At this time, there is no known cure or medication for persistent left superior vena cava connecting through coronary sinus to left-sided atrium. Treatment for this condition is typically surgical, and the goal of the surgery is to close off the abnormal connection and restore normal blood flow.

1. Transcatheter closure of the persistent left superior vena cava (PLSVC) using a device such as an Amplatzer septal occluder.

2. Surgical ligation of the PLSVC.

3. Transcatheter embolization of the PLSVC.

4. Transcatheter occlusion of the coronary sinus.

5. Surgical ligation of the coronary sinus.

6. Transcatheter embolization of the coronary sinus.

The most common cause of a persistent left superior vena cava connecting through the coronary sinus to the left-sided atrium is a congenital heart defect known as partial anomalous pulmonary venous return (PAPVR). This defect occurs when the pulmonary veins, which normally carry oxygenated blood from the lungs to the left atrium, instead connect to the right atrium or the superior vena cava. This causes the oxygenated blood to mix with the deoxygenated blood in the right atrium, resulting in a decrease in oxygen levels in the body. Other causes of this defect include certain genetic disorders, such as Turner syndrome, and certain types of heart surgery.

The symptoms of Persistent left superior vena cava connecting through coronary sinus to left-sided atrium can vary depending on the severity of the condition. Common symptoms may include shortness of breath, fatigue, chest pain, palpitations, dizziness, and fainting. In more severe cases, the patient may experience heart failure, arrhythmias, and even sudden death.

Persistent left superior vena cava connecting through coronary sinus to left-sided atrium is a rare congenital heart defect in which the left superior vena cava (LSVC) is connected to the left atrium through the coronary sinus instead of the right atrium. This defect can cause a variety of symptoms, including shortness of breath, fatigue, and chest pain. Treatment typically involves corrective surgery to reroute the LSVC to the right atrium.
