Post-mortem X-rays of 3 hearts before injection of barium gelatin mass (A, B, D) and the dissected coronaries of one heart not injected (C). A, 42-year-old white male who died of cardiogenic shock shows extensive, confluent calcification of the LAD coronary artery (long arrows) and focal discrete calcium deposits of the RCA (short arrows). B, 54-year-old white male who died of SCD outside the hospital. Extensive calcification of all three coronary arteries, particularly the RCA (white arrows), with diffuse confluent calcification. Note the circumferential calcification of the CIRC (black arrow). C, Coronary arteries of a 62-year-old white male who died SCD outside the hospital. The RCA (short thin arrow)shows focal calcification extending into the posterior descending artery. Extensive, confluent calcification is seen in the LAD coronary artery (long arrow), and the intimedius branch (fat arrow). D, 93-year-old white female who died as a result of cardiogenic shock secondary to a large anterior myocardial infarction. Relatively minimal calcification is present in the RCA (short white arrow), the LAD coronary artery (long black arrows), and CIRC (short black arrow) in this elderly patient.
