Anomalous origin of the left circumflex coronary artery from the pulmonary artery. A very rare congenital anomaly in an adult patient diagnosed by cardiovascular magnetic resonance

<p>Abstract</p> <p>Here we report for the first time on the diagnostic potential of cardiovascular magnetic resonance (CMR) to delineate the proximal course of an anomalous left circumflex coronary artery (LCX) originating from the right pulmonary artery in an adult patient with no other form of congenital heart disease. The patient was referred to our institution due to exertional chest discomfort. X-Ray coronary angiography showed a normal left anterior descending coronary artery (LAD) and right coronary artery (RCA), while the LCX was filled retrograde by collateral flow through the LAD and the RCA. The origin of the LCX was postulated to be the pulmonary artery, but the exact origin of the anomalous artery could not be depicted on conventional angiograms. CMR provided the unambiguous depiction of the origin of the anomalous LCX from the right pulmonary artery and the delineation of its proximal course in this case of a very rare coronary anomaly in adults.</p

Sudden death in a young female with an under-recognised coronary anomaly

Anomalies of coronary number and course represent an opinion-dividing topic in cardiopathology, particularly for their relationship with sudden cardiac death.To the best of our knowledge, we herein report the first fatal case of a young female whose coronary anatomy was characterised by the absence of any septal perforator branch in the proximal segment of the LAD.This case could be useful for pathologists, coronary angiographers, and interventional cardiologists in detecting this infrequent anomaly, thus providing a more accurate estimation of its incidence
