Coronary arterial fistula is an abnormal connection between a coronary artery and another structure, such as a vein, an artery, or a chamber of the heart. This condition is usually congenital, meaning it is present at birth, but it can also develop later in life. Coronary arterial fistulas can cause a variety of symptoms, including chest pain, shortness of breath, and palpitations. Treatment typically involves closing the fistula with a catheter-based procedure.

The most common symptoms of a coronary arterial fistula include chest pain, shortness of breath, palpitations, dizziness, fatigue, and fainting. Other symptoms may include a heart murmur, an irregular heartbeat, and an enlarged heart. In some cases, a coronary arterial fistula may cause heart failure.

Coronary arterial fistula is a rare congenital heart defect that occurs when an abnormal connection forms between a coronary artery and another structure, such as the aorta, pulmonary artery, or another coronary artery. The exact cause of this condition is unknown, but it is believed to be due to abnormal development of the coronary arteries during fetal development. Other possible causes include genetic mutations, infections, and trauma.

1. Transcatheter embolization: This is a minimally invasive procedure that involves blocking the fistula with a device such as a coil or plug.

2. Surgery: This involves closing the fistula with sutures or a patch.

3. Medical therapy: This involves taking medications to reduce the risk of complications such as stroke or heart attack.

5. Smoking

At this time, there is no cure for coronary arterial fistula. Treatment typically involves medications to reduce the risk of complications, such as high blood pressure, stroke, and heart attack. These medications may include beta-blockers, ACE inhibitors, and calcium channel blockers. In some cases, surgery may be necessary to close the fistula.
