[Comparison of clinical and postmortem evaluation of coronary artery stenosis: data on patients who died after coronary artery bypass surgery].

Comparison of quantitative clinical angiographic data with postmortem coronary angiographic and visual evaluation of transversal sections of coronary arteries (CA) data was made. CA of 25 patients who died after coronary artery bypass surgery were investigated. Comparison of clinical and postmortem angiographic data showed more frequent underestimation (12%) and overestimation (12%) of stenosis in clinical angiography in cases of right CA injury.
