“…Moreover, careful inspection of the coronary arteries is rarely performed in adults. Therefore, easily identifiable echocardiographic markers of ALCAPA might be helpful to avoid misdiagnosis (8)(9)(10). In adult ALCAPA patients, the blood from the high-pressure RCA artery fills the LCA via extensive collaterals and exits the LCA into the PA. RCA is usually ecstatic and easy to be identified.…”

Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery Detected by Echocardiography in an Asymptomatic Adult

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital malformation. It is unusual for an ALCAPA patient to survive to adulthood. We present a case of an asymptomatic 54-year-old woman with this syndrome in which visualization of a markedly enlarged and tortuous right coronary artery and intercoronary collaterals by echocardiography raises suspicion for this disease and subsequently guides a step-by-step diagnosis. The patient lives well without surgery 3 years after diagnosis.Key words: anomalous origin of the left coronary artery from the pulmonary artery, congenital heart disease, echocardiography (Intern Med 52: 233-236, 2013)

“…But the abundant intraseptal flow signals attracted the observer's attention and more detailed assessment of coronary arteries was given which resulted in the definitive diagnosis. In patients surviving over one year without treatment, coronary collaterals have been found to develop sufficiently to present obvious septal color flow signals in echocardiographic views 5,8–10 . The identification of these septal collaterals is the initial clue to the diagnosis in patients aging over one year.…”

The objective of this study was to analyze echocardiographic characteristics of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) and to explore the diagnostic value of transthoracic echocardiography. The echocardiographic characteristics of 8 patients hospitalized with ALCAPA from 2000 to 2005 were analyzed retrospectively, including the results of real time three-dimensional echocardiography in one case, and compared with angiographic results. Eight cases included 6 older type patients and 2 infant type patients. Echocardiography showed abnormal vessel inserting into pulmonary artery (PA), continuous shunt into PA and intercoronary collateral signals within the ventricular septum in all cases and bifurcate structure of the abnormal vessel with retrograde filling in 4 cases. The morphological and functional changes and valvular regurgitation induced by insufficient myocardial perfusion were also evaluated. In former 4 patients, 2 cases were misdiagnosed as right coronary artery-PA fistula and the other 2 cases were given an uncertain diagnosis of anomalous origin of the coronary artery because of the visualization of the echo-free linear structure which apparently arose from the aorta resembling a normal left coronary artery. The latter 4 patients were correctly diagnosed by excluding the aforementioned interference. The diagnosis of ALCAPA was confirmed by angiocardiography in all patients and by intraoperative findings in 4 patients. Based on the apprehension of ultrasonic features and the enhancement of diagnostic alertness, the echocardiography can evaluate ALCAPA accurately and give more information than angiography. It may be the first diagnostic choice.

“…Different imaging modalities can be used to diagnose this rare anomaly including echocardiography. 8 Patients diagnosed with ALPACA should undergo surgery without delay to restore the coronary circulation. The goals of intervention are twofold: to improve perfusion to the myocardium supplied by the LCA and to interrupt the coronary steal and to provide durable and reliable conduits.…”
