“…However some of them may present with chest pain, syncope, heart failure and sudden death [23]. Acute myocardial infarction has been also described [10,19]. Extravascular coronary compression results in dynamic obstruction which can cause effort angina as well as syncope [24] and anomalous coronary arteries with an inter-arterial course are associated with sudden cardiac death [25].…”

“…In complex clinical scenarios, CT and magnetic resonance imaging (MRI) are often complementary. CMR often allows to define the proximal course of an anomalous coronary artery, but is more limited for coronary assessment compared to CCTA (13,14). However, CMR allows to evaluate cardiac structure, function, myocardial perfusion, myocardial viability, tissue characteristics (edema, hyperemia, necrosis, myocardial hemorrhage, fatty infiltration, etc.)…”

Cardiogenic shock is a severe disease caused by primary failure of cardiac function. Myocardial infarction is the most common cause of cardiogenic shock. It is common in adults but rare in children. An anomalous left coronary artery originating from the right sinus of Valsalva with an inter-arterial course between the pulmonary trunk and aortic root is a rare isolated congenital anomaly, with a high risk of sudden cardiac death, particularly in the context of exercise. Coronary computed tomography angiography (CCTA) allows non-invasive evaluation of congenital coronary anomalies in adults and children, including the location of the anomalous origin, details of the intramural segment, and the angle between the ostium and proximal segment. However, there are few data describing the role of cardiac magnetic resonance (CMR) children because of long scanning time and several contraindications. This case report describes an 8-year-old male child with cardiogenic shock caused by acute myocardial infarction. CCTA revealed a left coronary artery arising from the right sinus of Valsalva with inter-arterial course, and a moderately narrowed mid-portion of left main coronary artery, while CMR indicated myocardial infarction which located in left ventricular anterior, septal and lateral wall, together with intramyocardial hemorrhage (IMH) and microvascular obstruction (MVO). Combined application of CCTA and CMR could show coronary artery anomalies, myocardial viability, tissue characteristics, and would play an important role in the diagnosis and assessment.

“…There are several reports on myocardial infarction and PCI involving an anomalous RCA with various origins, including an anteriorly displaced origin within the right coronary sinus, in the ascending aorta, left coronary sinus, and LCX in a dual LAD anomaly. [ 4 ] Commonly noted in these cases were delayed reperfusion due to difficulties in finding the anomalous RCA ostium and more serious sequelae due to technical difficulties during the procedures. It has not been established whether some types of coronary anomalies predispose an artery to atherosclerotic stenosis at the proximal segment.…”
