The constraint seems to be in getting the...
متن کاملClinical Implications of Congenital Absence of Circumflex Coronary Artery

Anomalous origins of coronary arteries from distal segments are rarely reported. Presented herein is a coronary anomaly in which the circumflex artery (CX) originated as a continuation of the posterolateral branch of the right coronary artery (RCA) w...
