==Overview==
Persistent left superior vena cava (PLSVC) is a very rare and yet the most commonly described thoracic venous anomaly in medical literature. Some patient may be associated with other congenital heart disease, such as ventricular septal defect, atrioventricular septal defect. Symptoms depend on where left superior vena cava flows to. If if flows to right atria, many patients of persistent left superior vena cava appear without symptoms. Otherwise, patients may appear [[anoxemia]]. [[Echocardiography]] and cardiac MRI can tell the diagnosis of persistent left superior vena cava. The mai treatment of persistent left superior vena cava is [[surgery]]. Prognosis of persistent left superior vena cava depends on where left superior vena cava flows to.

==What are the symptoms of persistent left superior vena cava?==
The signs and symptoms depends on where the left superior vena cava flows to. If it finally flows to right atria, patients may have no sign or aymptom. But if the left superior vena cava flows to flows to left atria, symptoms may include [[anoxemia]], such as [[fatigue]], [[weakness]], [[dizziness]] and [[shortness of breath]].

==Who is at highest risk?==
Persistent left superior vena cava (PLSVC) is a very rare and yet the most commonly described thoracic venous anomaly in medical literature. It has a 10-fold higher incidence with congenital heart disease. PLSVC often becomes apparent when an unknown PLSVC is incidentally discovered during central venous line placement, intracardiac electrode/pacemaker placement or cardiopulmonary bypass, where it may cause technical difficulties and life-threatening complications. PLSVC is also associated with disturbances of cardiac impulse formation and conduction including varying degrees of heart blocks, supraventricular arrhythmias and Wolff Parkinson White syndrome. We describe the case of an 86-year-old male with a history of coronary artery disease and chronic atrial fibrillation who presented with worsening dyspnea and syncopal episodes. An ECG was consistent with complete heart block. During lead placement for the pacemaker, a left subclavian approach was unsuccessful. A left venogram was performed through the brachial vein that demonstrated a left superior vena cava. The diagnosis was confirmed with echocardiography using a bubble study and also a chest CT. The anatomy was unique as there was anomalous left hepatic vein drainage into the right atrium. The case provides insight into the diagnostic modalities and clinical considerations of this unusual thoracic venous anomaly.
The cause of persistent left superior vena cava is not clear. Some patients with persistent left superior vena cava have other congenital heart disease.

Overview

Persistent left superior vena cava (PLSVC) is a very rare and yet the most commonly described thoracic venous anomaly in medical literature. Some patient may be associated with other congenital heart disease, such as ventricular septal defect, atrioventricular septal defect. Symptoms depend on where left superior vena cava flows to. If if flows to right atria, many patients of persistent left superior vena cava appear without symptoms. Otherwise, patients may appear anoxemia. Echocardiography and cardiac MRI can tell the diagnosis of persistent left superior vena cava. The mai treatment of persistent left superior vena cava is surgery. Prognosis of persistent left superior vena cava depends on where left superior vena cava flows to.

What are the symptoms of persistent left superior vena cava?

The signs and symptoms depends on where the left superior vena cava flows to. If it finally flows to right atria, patients may have no sign or aymptom. But if the left superior vena cava flows to flows to left atria, symptoms may include anoxemia, such as fatigue, weakness, dizziness and shortness of breath.

Who is at highest risk?

The cause of persistent left superior vena cava is not clear. Some patients with persistent left superior vena cava have other congenital heart disease.

When to seek urgent medical care?

Call your health care provider if your baby has symptoms of persistent left superior vena cava. If one emerges the following symptoms, seeking urgent medical care as soon as possible:

How to know you have persistent left superior vena cava?

  • Echocardiography: This kind of painless test can help the doctor closely examine persistent left superior vena cava. It uses sound waves to produce an image of the ventricles, atrium and great vessles. Echocardiogram can tell whether left superior vena cava flows to right areia or not. Further more, the doctor can measure the speed of blood flow by echocardiogram.
  • Chest x-ray: An x-ray image of chest allows the doctor to check the size and shape of your great vessles and heart.
  • Chest CT or MRI: A chest CT or MRI can demonstrate the details of the heart extremely well, such as the great vessles, vascular, atrial and ventricular structures and their relationships to one another.
  • Cardiac catheterization: This is not a common diagnostic measure for persistent left superior vena cava. In a catheter room, the doctor threads a thin tube through a blood vessel in the patient's arm or groin to an artery in the heart and injects dye to see great vessles, atria and ventricles on an x-ray. Cardiac catheterization can reveal associated cardiac abnormalities are known or suspected.

Treatment options

Treatment for patients with persistent left superior vena cava is observation and surgery. The selection depends on where left superior vena cava flows to and other association congenital heart disease.

  • Observation: If left superior vena cava flows to right atria, patient may have no symptom. This type of patient need no treatment. Regular check may need to observe the child.
  • Surgery: Surgical treatment of persistent left superior vena cava may be performed to direct the flow of left superior vena cava from left atria to right atria.
