BACKGROUND: The adult type of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is characterized by late presentation due to collateral coronary flow. Patients often present with long time recurrent angina or dyspnea. Surgical correction can be a challenge due to the vast collateral coronary circulation.
CASE PRESENTATION: A previously healthy 41-year-old male presented in the emergency room referring typical angina and dyspnea. Coronary angiography revealed ALCAPA. Surgical correction was indicated. Under cardiopulmonary bypass, the left main coronary artery ostium was isolated and directly reimplanted in the aorta. The patient was discharged from the hospital without complications and asymptomatic. Control coronary angiography showed enlarged left main coronary artery and regression of the collateral circulation.
CONCLUSION: Even with a well-developed collateral circulation, detachment of the left coronary artery and direct implantation in the aorta is feasible, achieving good long-term results.
