The present study reports the case of a 32-year-old-female patient, born in the city of Sao Paulo, Brazil, that underwent coronary angiography to investigate exercise intolerance and palpitations with positive test for myocardial ischemia in hemodynamics service in Real e Benemérita Associaçao Portuguesa de Beneficencia Sao Paulo-Sao Joaquim Hospital. During the hemodynamic examination she was diagnosed with Syndrome Bland-White-Garland, a rare congenital defect, estimating its incidence at 1: 300,000 live births. It was chosen to hospitalization for complementary tests and therapeutic decision. After detailed study of the case, we followed-up the patient with conservative treatment for 5 months with partial improvement of symptoms, but with myocardial scintigraphy showing drug induced ischemia, large to moderate extension, we indicated the surgical treatment. After 3 months, patient was asymptomatic with scintigraphy showing discreet extension of ischemia.

The Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA), known as Bland-White-Garland Syndrome, is a rare congenital defect (1:300,000 live births) which has high mortality rate in the first year and only 10-15% reach adulthood .
A 32-year-old female, underwent coronary angiography to investigate exercise intolerance and palpitations with positive test for myocardial ischemia. Transthoracic echocardiogram showed ejection fraction of 69% without functional disorder.
Coronary angiography (Figure 1) showed a dilated right coronary irrigating the posterior side of the left ventricle, long and irregular left coronary trunk (LCT) coming out of the trunk of the pulmonary artery, right coronary artery with well-developed collateral circulation of the left coronary and the diagnose of ALCAPA was performed .
A tomography of the coronary arteries (Figures 2 and 3) showed the anomalous origin of the LCT and all coronary anatomy adapted to the low oxygen blood. Asymptomatic after use of beta-blocker, the patient was discharged for clinical follow-up .
On the third month of follow-up the patient begun to experience chest pain with exercises despite of the clinical treatment. The myocardial scintigraphy showed stress induced hypo perfusion of the ventricle's wall irrigated by the Anterior Descending coronary. Thus, the surgical treatment was indicated .
The surgical correction was the re-implantation of left coronary in the aorta. A bypass of the left internal thoracic artery to anterior descending artery was made to ensure the blood flow. After 3 months a new myocardial scintigraphy showed reduced ischemic area at rest and under stress, and reduction in symptomatology .
The clinical treatment was not sufficient to eliminate both symptoms and ischemia. On the other hand, surgical correction of the anomaly showed to be effective on reducing ischemia and symptoms.
