Introduction and Aim: Coronary computer tomography angiography is a unique non-invasive imaging technique with the capability to provide information regarding plaque quantity, burden and structure. A reliable registry is required to use the data of these examinations in research projects. The difficulty is that registries need double data entry simultaneously to the hospital information system., Method: Our registry solves this problem through a structured reporting tool, which generates clinical report and stores all data simultaneously. The automatically generated report is based on international guidelines., Results: Between August 1. 2014 and September 1. 2015 we registered the data of 2866 patients. Coronary plaque was observed in 77.03% of the patients, 33.18% of the plaques were calcified. Severe stenosis was present in 13.71% of the patients., Conclusions: The structured reporting decreases reporting time, eliminates double data entry related errors. Our goal is to initiate a nationwide, unified registry, the National Plaque Registry and Database. Orv. Hetil., 2017, 158(3), 106-110.

Numerous clinical studies using coronary computed tomography angiography (CTA) and conventional invasive coronary angiography (ICA) confirmed the strong relation between atherosclerotic disease burden and risk of adverse events. Few studies have compared coronary CTA and ICA regarding semiquantitative plaque burden measurements, reproducibility, and cardiovascular risk assessment. We enrolled 71 consecutive patients (mean age 62 ± 9 years, 37% women) from the Genetic Loci and the Burden of Atherosclerotic Lesions study (NCT01738828), who underwent 256-slice multidetector row coronary CTA and ICA at a single site. On average, 42 ± 32 days passed between the 2 examinations. A total of 1,016 coronary segments were imaged by both CTA and ICA according the 18-segment Society of Cardiovascular Computed Tomography classification. We excluded 16 segments treated with coronary stents. Overall, 1,000 segments were evaluated for the presence of stenosis severity (<25%: minimal, 25% to 49%: mild, 50% to 70%: moderate, 70% to 99%: severe, 100%: occlusion). We calculated the segment involvement score (SIS) and segment stenosis score. Patients were classified into 4 groups: extensive obstructive (SIS >4 and ≥50% stenosis), extensive nonobstructive (SIS >4 and <50% stenosis), nonextensive obstructive (SIS ≤4 and ≥50% stenosis), or nonextensive nonobstructive (SIS ≤4 and <50% stenosis). CTA detected coronary artery plaques in 49%, whereas ICA showed coronary plaques in 24% of the analyzed 1,000 segments (p <0.001). CTA detected atherosclerotic plaque in 35% of coronary segments where ICA was negative, whereas ICA detected plaque only in 3% of segments where CTA was negative. CTA-based segment scores were significantly greater, SIS: 6.9 ± 3.0 versus 3.3 ± 2.0, segment stenosis score: 16.4 ± 8.8 versus 9.4 ± 6.8 (p <0.001 for both). In conclusion, coronary CTA detected approximately twice as many coronary segments with plaque compared to ICA, which resulted in 52% of the patients being assigned to a greater risk category., (Copyright © 2016 Elsevier Inc.
