Thorough examination of the coronary arteries is essential when performing medicolegal autopsies. In some cases, evaluation is optimized by using postmortem angiography before dissection. Unfortunately, most techniques are far too time-consuming to be readily employed by forensic pathologists. We describe a simple technique of "subtraction angiography" that provides valuable information in a timely manner in cases that can benefit from postmortem angiographic analyses. We find the technique particularly helpful in cases that have had invasive coronary artery procedures contemporaneous with death.
