Clinical experience regarding the diagnostic value of segment-by-segment coronary computed tomography angiography in comparison with that of invasive coronary angiography / Experiência clínica na avaliação segmento por segmento demonstrando o valor diagnóstico da angiotomografia das artérias coronárias em comparação com o cateterismo em uma análise de 844 segmentos
The degree of coronary stenosis was evaluated in a total of 844 arterial segments. The diagnostic performance of CCTA was good, with a sensitivity of 82.3%, a specificity of 96.4%, and a negative predictive value of 97.7% (95% CI 96.5-98.5). In the segment-by-segment analysis, CCTA had excellent accuracy for the left main coronary artery and for other segments.
Conclusion:
In clinical practice at general hospitals, CCTA appears to have diagnostic performance comparable to that of ICA.
