Deviation in Decision Making in Bifurcational Lesions Intervention Based on CT Coronary Angiography Compared to Invasive Coronary Angiography

Abstract

SUMMARY I n the evaluation of patients with suspected coronary artery disease (CAD), the role of non-invasive imaging has increased exponentially over the past decades, particularly in patients with an intermediate likelihood of CAD. Non-invasive imaging plays an important role in risk stratification and selection of further treatment strategies. More recently, multi-slice computed tomography (MSCT) has been proposed as an alternative imaging modality for evaluation of patients with suspected CAD. With the recently introduced 64-slice MSCT, high sensitivity (96.7%) and specificity (97.5%) for the detection of significant (> 50% luminal narrowing) stenosis have been reported which has made non-invasive coronary angiography Using 64-slice CT a modality that allows significant coronary stenosis to be reliably excluded. The current study aimed to assess the accuracy of determining the medina classification, angle measurement and plaque composition and their effect on choosing the appropriate intervention technique based on multislice CT coronary angiography in comparison to invasive coronary angiography in bifurcational lesions intervention. The current study assessed 40 patients who underwent MSCT coronary angiography then invasive coronary angiography to assess the bifurcational lesions by CT vs IC
