Impact of intravascular enhancement, heart rate, and calcium score on diagnostic accuracy in multislice computed tomography coronary angiography.

2005

PURPOSE: To assess the effect of intravascular enhancement, heart rate, and calcium score on diagnostic accuracy in the detection of significant coronary artery stenosis using 16-row multislice computed tomography (MSCT). MATERIALS AND METHODS: One hundred patients (88 males; 59+/-11 years) with suspected coronary artery disease who had undergone conventional coronary angiography (CA) and MSCT-CA were retrospectively enrolled for the study. Patients underwent a MSCT-CA, with the following protocol: collimation 16x0.75 mm, gantry rotation time 420 ms, feed/rotation 2.8 mm, kV 120, mAs 400-500. The protocol for contrast material administration was 100 ml of Iodixanol 320 mgI/ml at 4 ml/s and …

Five-Year Results of the Bioflow-III Registry:Real-World Experience with a Biodegradable Polymer Sirolimus-Eluting Stent

2018

Abstract Purpose We aimed to assess long-term safety and performance of the Orsiro sirolimus-eluting coronary stent with biodegradable polymer in a large unselected population and in pre-specified subgroups. Methods BIOFLOW-III is a prospective, multicenter, international, observational registry with follow-up visits scheduled at 6 and 12 months, and at 3 and 5 years ( NCT01553526 ). Results 1356 patients with 1738 lesions were enrolled. Of those, 392 (28.9%) declined to participate in the study extension from 18 months to 5 years, 37 (2.7%) withdrew consent, and 89 (6.6%) were lost to follow-up. At 5-years, Kaplan-Meier estimates of target lesion failure, defined as a composite of cardiac …
