Establishment of a Two Coronary Artery System in Anomalous Origin of Left Coronary Artery from Pulmonary Artery

Anomalous origin of the left coronary artery arising from the pulmonary artery is a relatively rare disease. Within 2 years, from August 2011 to June 2013, Cardiovascular Centre of Hue Central Hospital had received and treated 5 cases of this disease. The patients were from 4 weeks to 17 months old (median 4 months), and had an average weight of 6 kg (range 3-10 kg). All 5 cases were accurately diagnosed by echocardiography and operated successfully with reconstruction of left main coronary artery. Troponin T was used as a marker to identify the myocardial infarction after surgery. All patients had been supported with interlope after cardiac repair and in the postoperative period, the supporting time varied from several days to several weeks, depending on the hemodynamic and cardiac function, but none of the patients required postoperative extracorporeal membrane oxygenation or died. Ejection fraction returned to normal values in 4 patients after 3 months; however, in one patient with preoperative ejection fraction decreased to 18%, this figure was almost unimproved during 12 months of follow-up (20%). Early diagnosis and early surgery is to avoid chronic heart failure, requiring the surgeon to choose the most appropriate technique for each patient.
