Abstract
|
|
|
A persistent left superior vena cava is the most common anomaly of the superior caval system. Usually the persistent left superior vena cava is connected with the right atrium via the coronary sinus, resulting in no physiologic derangement :
however in
7 to 8 percents of the patients with a persistent left superior vena cava, the anomalous vessel communicates with the left atrim. In the absence of obstruction to the flow from the left atrium to the left ventricle, this anatomic situation
usually
results in right to left shunting of varying degrees.
We recently experienced a case of persistent left superior vena cava in a 52-year-old female who complained of chest discomfort, epigastric pain and dyspnea (NYHA functional class II). Cine-angiography showed that the contrast passed from the
left
SVC
through the dilated coronary sinus into the right atrium. And right sided SVC was not seen.
The patient was treated with conservative measures and discharged with improved condition.
