Surgical Repair of a Giant Aorto–Left Ventricular Fistula

Abstract

Aortoventricular fistula, a rare congenital or acquired defect of the aortic wall, is characterized by an abnormal connection between the aorta and one of the ventricles. Symptom severity correlates with the diameter of the fistula and with the acute or chronic timing of presentation. The diagnosis is usually made by using echocardiography, and surgical treatment is necessary to avoid progression to heart failure. We describe the case of a 27-year-old woman who underwent successful surgical repair of an aortoventricular fistula that originated from the right coronary sinus and extended into the left ventricle through the interventricular septum. In addition to the patient's case, we briefly discuss this unusual condition

“…The causes of aortoventricular fistula include aortic dissection, chest trauma, infective endocarditis, and aortic valve surgery, with rupture of a congenital or acquired SVA the most common cause. 1 Most originate in the right coronary sinus and are associated with the right ventricle, as was the case for our patient. Although a good long-term outcome of surgical repair of ruptured SVA has been reported, aortic regurgitation might occur after this surgical repair.…”
