“…The overall sensitivity and specificity of MDCT angiography for the detection of graft patency were 87% and 97%, respectively. Although the sensitivity was somewhat low (but acceptable), the specificity, PPV (94%), and NPV (93%) were comparable with the results of other studies that used 16-slice systems [Yamamoto 2006;Houslay 2007;Uva 2008;von Kiedrowski 2009]. The largest study thus far, which was conducted with 64-slice MDCT angiography in 138 patients, reported sensitivity and specificity values of 97% each for the evaluation of bypass graft occlusion and stenosis [Meyer 2007].…”

“…Sudden deaths can also occur in patients undergoing cardiovascular surgery. MDCT angiography allows for the non-invasive evaluation of coronary bypass graft patency with a high diagnostic accuracy [53,54]. MDCTA is a reliable non-invasive diagnostic method that can clearly display the stent lumen and is especially helpful for patient follow-up.…”

Postmortem imaging of sudden cardiac death

Postmortem imaging is increasingly used in forensic practice in cases of natural deaths related to cardiovascular diseases, which represent the most common causes of death in developed countries. While radiological examination is generally considered to be a good complement for conventional autopsy, it was thought to have limited application in cardiovascular pathology. At present, multidetector computed tomography (MDCT), CT angiography, and cardiac magnetic resonance imaging (MRI) are used in postmortem radiological investigation of cardiovascular pathologies. This review presents the actual state of postmortem imaging for cardiovascular pathologies in cases of sudden cardiac death (SCD), taking into consideration both the advantages and limitations. The radiological evaluation of ischemic heart disease (IHD), the most frequent cause of SCD in the general population of industrialized countries, includes the examination of the coronary arteries and myocardium. Postmortem CT angiography (PMCTA) is very useful for the detection of stenoses and occlusions of coronary arteries but less so for the identification of ischemic myocardium. MRI is the method of choice for the radiological investigation of the myocardium in clinical practice, but its accessibility and application are still limited in postmortem practice. There are very few reports implicating postmortem radiology in the investigation of other causes of SCD, such as cardiomyopathies, coronary artery abnormalities, and valvular pathologies. Cardiomyopathies representing the most frequent cause of SCD in young athletes cannot be diagnosed by echocardiography, the most widely available technique in clinical practice for the functional evaluation of the heart and the detection of cardiomyopathies. PMCTA and MRI have the potential to detect advanced stages of diseases when morphological substrate is present, but these methods have yet to be sufficiently validated for postmortem cases. Genetically determined channelopathies cannot be detected radiologically. This review underlines the need to establish the role of postmortem radiology in the diagnosis of SCD.

“…Only 62% to 74% of grafts were evaluable, and sensitivities and specifi cities were between 95% and 100% for the assessment of graft patency. Sensitivities and specifi cities were between 80% and 96% for the detection of signifi cant graft stenosis [7,[19][20][21][22][23][24][25][26][27][28][29]. In case of graft patency, detection of de novo lesions in nongrafted coronary arteries and coronary segments located proximal to the distal graft anastomosis may be of therapeutic relevance for interventional or surgical planning.…”
