Anomalous left coronary artery arising from the pulmonary artery (adult type)
American Heart Journal, 1950
, 21 consecutive infants aged less than six months (mean (SD) 2-6 (1 2)) were admitted with anomalous origin of the left coronary artery from the pulmonary artery. In the first 12 patients, who were seen up to 1982, operation was performed after the age of one year (mean (SD) 29 (29) months) (group 1). The next nine infants, seen from 1983 to 1987, had their operations within a few weeks of the onset of symptoms (mean (SD) age 4-8 (1 4) months) (group 2). In group 2 the left coronary artery was relocated into the aorta, whereas in group 1 there was additional resection of the left ventricular wall or mitral valvoplasty or both. At presentation there were no differences in age, clinical condition, heart enlargement, and echocardiographic left ventricular dysfunction between groups 1 and 2. Seven of the 12 patients in group 1 died, five while they were awaiting operation (three died suddenly at home) and two at operation. The five survivors are doing well 6-4 (3-1) years after operation with normal left ventricular function which improved slowly over several months after operation. Two of the nine patients in group 2 died; both deaths occurred at or soon after operation. The seven survivors are doing well 1 8 (0 9) years after operation. In three, left ventricular function recovered within three weeks; and there was even partial or total regression of the Q waves in the supposedly necrotic areas. In the remaining four the pattern of improvement in left ventricular function resembled that in group 1. Operation should be undertaken early in infants with anomalous left coronary artery arising from the pulmonary artery because the procedure is relatively safe, prevents a high natural mortality, and offers a better chance of a faster recovery of left ventricular function.
Isolated Anomalous Origin of Right Coronary Artery from the Main Pulmonary Artery
Journal of Cardiac Surgery, 2005
The anomalous origin of the right coronary artery (ARCA) from the main pulmonary artery (MPA) is a rare congenital cardiac malformation and usually associated with other cardiac anomalies. Most patients with isolated ARCA from MPA remain asymptomatic, but they may develop myocardial ischemia and even sudden death. We reported an asymptomatic 7-year-old boy referred for evaluation of a heart murmur. Isolation of ARCA from MPA was diagnosed by echocardiography and then confirmed by cardiac catheterization and angiography. The right coronary artery was re-implanted into the ascending aorta. A preoperative thallium-201 myocardial perfusion showed a myocardial ischemia pattern in the anterolateral septal area after a dipyridamole stress test; the ischemia was completely resolved after surgery.
Anomalous origin of the left coronary artery from the pulmonary artery

ABSTRACT Anomalous origin of the left coronary artery from the pulmonary artery (ALCA-PA) is a rare form of congenital heart disease. In this report, three cases with this anomaly are described; two patients presented in infancy with heart failure from myocardial ischemia and infarction, while the third was asymptomatic and ALCA-PA was diagnosed during evaluation of a residual murmur after surgery for associated cardiac defects (ventricular septal defect and patent arterial duct). All three cases underwent aorto-pulmonary tunnel repair (Tukeuchi procedure), and to our knowledge two of them are the first infantile cases reported in Turkey.

Anomalous origin of the left coronary artery (LCA) from the pulmonary artery (ALCAPA) syndrome is a potentially lethal and rare congenital cardiac anomaly (for approximately 1 in 300,000 live births). ALCAPA syndrome mostly presents in the first few months of life. Left untreated, the mortality rate in the first year of life is 90% secondary to myocardial ischemia or infarction and mitral valve insufficiency leading to congestive heart failure. When pulmonary arterial pressure decreases, it results in reversal of flow so that LCA drains from the right coronary artery through collateral vessels into the pulmonary artery. This phenomenon causes ischemia or eventually infarction of the anterolateral left ventricular wall. Sudden death may occur because of inadequate collateral circulation between LCA and the right coronary artery and/or development of arrhythmia. ALCAPA can be found both in infants and in older individuals, with the absence or presence of strong collateral circulation ...

Isolated anomalous origin of the right coronary artery from the main pulmonary artery is a rare congenital anomaly, and few cases have been reported in the pediatric age group. Here in, we report an asymptomatic case of a 2-month-old male infant who has been diagnosed as anomalous origin of the right coronary artery from the main pulmonary artery during the evaluation for cardiac abnormalities. For a suspicion on echocardiography, cardiac catheterization and coronary angiography performed to verify the diagnosis of anomalous origin of the right coronary artery from the main pulmonary artery. The patient underwent surgery and did well after two months follow up. Early diagnosis may prevent patients from cardiovascular complications.
