Short left circumflex artery.
There was evidence of posterior infarction in 61 of 212 hearts studied. The condition was associated with a relatively short circumflex branch of the left coronary artery (LCX) in 24 hearts and with a longer LCX in 37 hearts. Total occlusion of LCX was found in two (8%) hearts with a shorter circumflex branch and in 27 (73%) hearts with a longer circumflex branch. The right coronary artery (RCA) was occluded in nearly all hearts with posterior infarction. In those hearts with a shorter LCX, occlusion of RCA appeared to be the major factor in the pathogenesis of posterior myocardial infarction.
