Reconstruction of anomalous left coronary artery from pulmonary artery in an adult patient: a case report

BACKGROUND: Anomalous left coronary artery from the pulmonary artery is a congenital heart disease in which myocardial ischemia occurs within 1 year of birth. Adults have been reported to survive owing to the development of collateral perfusion from right coronary artery. In these cases, however, revascularization is necessary to prevent sudden cardiac death. CASE PRESENTATION: A 62-year-old female gradually started experiencing dyspnea during exercise. Coronary computed tomography revealed that the left coronary artery arose from the main pulmonary artery. The patient was subsequently diagnosed with adult-type, anomalous left coronary artery from the pulmonary artery. She underwent a surgery, in which a 6-mm vascular prosthesis was passed through the main pulmonary artery to anastomose the left coronary artery and ascending aorta. CONCLUSION: Our reconstructive technique using vascular prosthesis is effective for anomalous left coronary artery from pulmonary artery in adults.
