ABSTRACT
Anatomy Septal rupture is usually associated with complete occlusion of a coronary artery: most
commonly anteroapical (60-80%) in location as a result of full-thickness infarction following occlusion of LAD; alternatively, postero-septal rupture (20-40%) following inferoseptal infarction associated with occlusion of a dominant RCA or circumflex coronary artery. In 5-10% of cases the defects are multiple.
