ABSTRACT: Rationale
Cases of coronary artery fistula having a connection with the cardiac cavity are rare. Here, we report a case in which 2 coronary arteries empty into the left ventricular cavity together.Patient concerns
A 63-year-old woman who was diagnosed as having hypertension 20 years prior presented with dyspnea.Diagnoses
The coronary angiography revealed coronary artery fistula.Interventions
Chest X-ray showed pulmonary edema. Transthoracic echocardiography revealed moderately decreased left ventricular (LV) function and increased LV end-diastolic volume and mass index. Coronary angiography and cardiac computed tomography revealed that 2 coronary arteries joined together at the distal end and directly drained into the left ventricular cavity bypassing the myocardial capillary vessels. We started medical treatment for heart failure with an angiotensin-converting-enzyme inhibitor, loop diuretic, and spironolactone.Outcomes
The pulmonary edema improved rapidly. The patient did not experience dyspnea after discharge, and follow-up echocardiography showed improved cardiac function.Main lesson
Coronary artery fistula could be found incidentally on coronary angiography performed for varied reasons. Physicians must decide carefully whether the fistula needs to be treated in view of the clinical context.
