Yj. Lim et al., LEFT-VENTRICULAR PAPILLARY-MUSCLE PERFUSION ASSESSED WITH MYOCARDIAL CONTRAST ECHOCARDIOGRAPHY, The American journal of cardiology, 78(8), 1996, pp. 955
This myocardial contrast echocardiographic study shows that left ventr
icular posteromedial papillary muscle is supplied by either the right
or left coronary artery in most subjects, but may be supplied by both
coronary arteries. The posteromedial papillary muscle and its adjacent
area may be supplied by a different coronary artery.
