It has previously been reported that the length of the left main coronary artery is short in patients with left bundle branch block (LBBB) and that an unexpectedly large number of LBBB patients had dominant left coronary arterial distribution. The present coronary arteriographic study of 13 patients with LBBB revealed a mean length of the left main coronary artery (±1 SD) of 10.9±6.0 mm, a measurement which was not significantly different (P>0.5) from that of the left coronary arteries in 78 patients in a control group (10.0±3 mm). The arterial distribution patterns showed a contribution of the right coronary artery to the posterior descending artery in 12 of the 13 patients with LBBB. Coronary artery anatomy does not appear related to the presence of LBBB.
