Which part of the heart is affected by the following coronary branch occlusions?

Left anterior descending coronary artery, LAD: anterior wall of left ventricle and interventricular septum.

Left circumflex coronary artery, LCX: lateral wall of left ventricle; sometimes posterior wall of left ventricle also, if the LCX is dominant. Dominant coronary artery is the artery which crosses the crux of the heart i.e. Junction of interventricular and interatrial grooves posteriorly.

Obtuse Marginal, OM: lateral wall of left ventricle.

Right coronary artery, RCA: right ventricle and inferior wall of left ventricle; and sometimes posterior wall of left ventricle, if RCA is dominant.
