Abstract
Coronary artery fistulas are uncommon entities with communication between the coronary artery and cardiac structure. We encounter a 70-year-old, asymptomatic woman with a large right coronary artery to left ventricle fistula. Non-invasive echocardiogram was helpful in detecting an enlarged right coronary that drained from the aorta into the left ventricle. Clinical importance of coronary artery fistula is due to an increased risk of heart failure, myocardial ischemia, and rupture. Treatment of asymptomatic patients without significant shunting is controversial. We decided to follow-up on her medically without surgical closure of the fistula because her hemodynamics are stable.
Echocardiogram is very useful to diagnose and evaluate these diseases.
