Quantitative coronary angiography (QCA) remains to play an important role in clinical trials and post-marketing surveillance related to the safety and efficacy of new PCI devices. In this …

Conventional QCA-based on single-vessel assessment. A team at the Thoraxcenter in Rotterdam, led by Professor Patrick W. Serruys and Professor Hans Reiber, developed a contour …

In this communication, we describe a novel methodology for reporting bifurcation using a new version of the CAAS 5 software (Pie Medical Imaging, Maastricht, The Netherlands). The …

In the last decade, the limitations of conventional, 2D, “single-vessel” QCA have been addressed by further advances of QCA software, including the introduction of 3D QCA and dedicated …

Dec 17, 2024 · Quantitative coronary angiography (QCA) provides reliable information about vascular dimensions, overcoming these limitations. Poststenting postdilation with appropriately …

Quantitative coronary angiography (QCA) is a software-based technique that quantifies coronary stenosis by comparing the diameter of the stenosis with a reference diameter, usually the …

Our Core Lab provides both 2D and 3D QCA. Out-of-plane magnification and foreshortening errors are minimized by calculating a true geometric shape in the 3D space from two or more …

Nov 23, 2010 · The purposes of this study were to develop a new methods (MR-QCA) to determine stenosis severity on whole heart coronary MRA, and to evaluate the accuracy of …

Objectives: To compare visual estimation with different quantitative coronary angiography (QCA) methods (single-vessel versus bifurcation software) to assess coronary bifurcation lesions. …

Feb 1, 2009 · This consensus statement outlines the limitations of conventional QCA in the bifurcation application, and outlines a new standard approach for the analysis and reporting of …
