QCA (Quantitative Coronary Analysis) is the worldwide accepted standard for assessment of coronary artery dimensions. The QCA workflow can assist in the selection of the optimal balloon and stent. QCA features single vessel and bifurcation analysis including calibration, automatic contour detection and quantification of the severity of stenosis.
