Question:

What is the most common symptom from coronary sinus communication to the left atrium?
1. shortness of breath
2. cyanosis
3. orthopnea
4. angina
5. asymptomatic





Answer:

The correct answer for the question "What is the most common symptom from coronary sinus communication to the left atrium?" is:

5. asymptomatic



Explanation
It is mostly asymptomatic and found in autopsy. [Clinical presentation will vary according to the presence of arrhythmia as well as the volume and direction of shunting; however this anomaly is most often discovered incidentally in asymptomatic patients].

Abstract
Coronary sinus anomalies are rare. They can be associated with other vascular anomalies such as persistent left superior vena cava or can occur in isolation. We present a rare case of an isolated coronary sinus communication to the left atrium. This anomaly may be clinically relevant in the setting of significant left-to-right shunting or when shunt reversal results from right-sided heart failure. It may also be significant in cases of persistent atrial fibrillation after attempted pulmonary vein isolation.
