Impact of coronary calcium score on diagnostic accuracy for the detection of significant coronary stenosis with multislice computed tomography angiography.
One hundred twenty patients in sinus rhythm with suspected coronary artery disease who underwent multislice computed tomography of the heart and conventional coronary angiography were retrospectively selected. The population was divided into 2 groups depending on their calcium score (CS) (e.g., low CS and high CS). The diagnostic accuracy of multislice computed tomographic scans for detecting significant lesions (>50% lumen reduction) in both groups was compared with quantitative coronary angiography. The sensitivity and specificity of multislice computed tomography were 90% and 92%, and 97% and 91% for low and high CS groups, respectively.
TCT-664 Twelve-Month Clinical Outcomes Comparing Biodegradable Polymer Sirolimus-Eluting Stent Versus Durable Polymer Everolimus-Eluting Coronary Stents in Patients With De Novo Native Coronary Artery Lesions: The meriT-V Randomized Trial
The aim of this study is to compare the safety and efficacy of the biodegradable polymer coated sirolimus-eluting coronary stent (SES, BioMime™, Meril Life Sciences, India) with durable polymer coated everolimus-eluting coronary stent (EES, XIENCE family, Abbott Vascular, California, USA) in de
Higher intracoronary attenuation improves diagnostic accuracy in MDCT coronary angiography
OBJECTIVE: The purpose of this study was to investigate whether the amount of intracoronary attenuation influences the diagnostic accuracy of MDCT coronary angiography in the detection of clinically significant stenosis. MATERIALS AND METHODS: One hundred twenty patients in sinus rhythm with suspected coronary artery disease who underwent MDCT of the heart and conventional coronary angiography were retrospectively selected. The population was divided into two groups depending on median (326 H) coronary vascular enhancement (i.e., low attenuation and high attenuation). The diagnostic accuracy of MDCT for the detection of clinically significant coronary artery lesions (> or = 50% lumen reduct…
