In recent years, post mortem multi-slice computed tomography (MSCT) is increasingly applied for forensic and pathologic examination. However, classical dissection remains dominant in everyday practice. Lack of quantifiable data on the coronary system has become a disadvantageous attribute of traditional autopsy. Therefore, post mortem MSCT angiography was performed in 80 ex corpo hearts with the aim of improving the accuracy and quantitative documentation of pathologic and forensic diagnoses of coronary artery disease (CAD). Hearts were perfused by introducing a new oily or synthetic resin, or using both contrast materials successively. Then the perfused organs were processed for imaging. Detailed angiographic analysis enabled us to localize, map and quantify coronary calcifications, stenoses, and to characterize the types of atherosclerotic plaques. Significant early or late complications of widely used percutaneous coronary interventions (PCI) and coronary bypass surgery (CABS) could be revealed using CT analysis. Furthermore, by using our oily contrast material and CT imaging, we could identify and visualize the clinically important small caliber nodal arteries (diameter 0.4–2.0 mm). The present work suggests that post mortem CT angiography and post-processing of the data may improve the quality of pathologic and forensic diagnosis. Our collection of coronary casts including digital data are available for further analysis.

Coronaryangiography may reveal normal coronary arteries in a significant proportion (20%–30%) of patients presenting with typical angina pectoris [ 1 ]. Although non-cardiac causes may be responsible for the chest

Tissue level myocardial perfusion is one of the most important prognostic factors after successful recanalisation of the occluded coronary artery in patients suffering acute ST elevation myocardial infarction (STEMI). The primary objective of the present study was to examine the relationship between videodensitometric myocardial perfusion parameters as assessed on coronary angiograms directly following successful recanalization therapy and magnetic resonance imaging (MRI)-derived myocardial tissue loss late after STEMI. The study comprised 29 STEMI patients. Videodensitometric parameter Gmax/Tmax was calculated to characterize myocardial perfusion, derived from the plateau of grey-level intensity (Gmax), divided by the time-to-peak intensity (Tmax). Myocardial loss index (MLI) was assessed by cardiac MRI following 376 ± 254 days after PCI. Results: Signifcant correlations could be demonstrated between MLI and Gmax (r = 0.36, p = 0.05) and Gmax/Tmax (r = 0.40, p = 0.03) using vessel masking. Using receiver operating characteristic curve analysis, Gmax/Tmax < 2.17 predicted best MLI = 0.3, 0.4, 0.5 and 0.6 with good sensitivity and specifcity data, while Gmax/Tmax < 3.25 proved to have a prognostic role in the prediction of MLI = 0.7. Conclusions: Selective myocardial tissue level perfusion quantitative measurement method is feasible and can serve as a good predictor of myocardial tissue loss following STEMI and revascularization therapy.

Type IV dual left anterior descending artery (LAD) anomaly constitutes a rare subset of coronary anomalies in which the anterior and anterolateral wall of the left ventricle is supplied by a short LAD originating from the left coronary artery along with a long LAD that originates from the right sinus of Valsalva. Albeit rare, the angiographic presentation is challenging since the appearance of the short LAD is similar to a total occlusion beyond first few diagonal or septal branches. Here, we present a series of four cases with type IV dual LAD anomaly with different clinical and angiographic presentations.
