“…1 mm error in lengths of 40 mm and higher in both studies). Another study using similar methodology (a marker wire as a benchmark for intracoronary length measurements) showed very similar precision in quantitative evaluation of coronary anatomy as our present study [9]. However, 3D reconstructions in that study were generated from rotational angiography.…”

“…more precise stent selection, tackling chronic total occlusions, remote or robotic guidance of PCI). But only recently have the advances in computer power made simple and fast 3-dimensional rendering of angiographic images possible [6][7][8][9][10]. Three-dimensional angiography proved useful in assessment of one of the most complex interventional challenges, left main coronary anatomy [20].…”

“…Although 2D QCA has been well validated in phantoms and its reproducibility is well established, foreshortening of the arterial segment of interest in a two-dimensional image continues to be a significant problem when determining lesion length, eccentricity, and tortuosity [2,3]. Due to these limitations, coronary angiography modeling using threedimensional QCA on the basis of images and structures visualized and captured during standard and rotational angiography was introduced [4,5] and is currently being evaluated for its utility in clinical practice [6][7][8][9][10].…”

A b s t r a c tAim: To determine if three-dimensional quantitative coronary angiographic analysis (3D QCA) provides an advantage over twodimensional (2D QCA) by increasing accuracy and precision of length measurements through compensating for foreshortening inherent to 2D images.Material and methods: A total of 800 inter-marker length measurements were performed (8 per wire, 5-40 mm) with novel 3D software and standard 2D software and compared with the true lengths of the inter-marker distances on the wire in coronary vessels of 21 patients recruited.Results: 2D QCA generally underestimated true length in comparison to 3D, and the discrepancy increased with absolute length. In contrast, 3D QCA showed a minimal difference from true length over the examined range of lengths.Conclusions: 3D QCA minimizes errors in length measurements associated with foreshortening, shows minimal difference from true length, and performs significantly better in comparison to 2D QCA. The advantage of 3D QCA is more pronounced at longer lengths.Key words: 3D, 2D, quantitative coronary angiography (QCA) S t r e s z c z e n i e Cel: Określenie, czy trójwymiarowa, ilościowa analiza angiograficzna naczyń wieńcowych (3D QCA) ma przewagę nad standardową oceną dwuwymiarową (2D QCA) polegającą na zwiększeniu dokładności i precyzji pomiarów długości oraz wyeliminowaniu skrócenia typowego dla analiz 2D.Materiał i metody: Wykonano ogółem 800 pomiarów długości odcinka pomiędzy markerami na prowadnikach wieńcowych wprowadzonych do tętnicy wieńcowej (8 długości na prowadniku w zakresie 5-40 mm) z zastosowaniem oprogramowania 3D i standardowego oprogramowania 2D w porównaniu ze znanymi odległościami znaczników na prowadniku wieńcowym u 21 pacjentów poddanych koronarografii.Wyniki: W analizie 2D QCA pomiary były z reguły zaniżone w stosunku do rzeczywistej długości mierzonego odcinka, przy czym wielkość błędu wzrastała wraz z bezwzględną długością mierzonego odcinka. Analizy za pomocą 3D QCA wykazały minimalne różnice pomiarów w stosunku do rzeczywistych odległości pomiędzy markerami w całym zakresie badanych długości.

“…This procedure is generally known as quantitative coronary angiography (QCA). With the development of 3D coronary artery reconstruction algorithms, QCA can now performed in 3D reconstruction of the lesion of interest (Figure 2) (Dvir et al, 2008;Garcia et al, 2007), which is shown to be in an agreement with ground truth measurements via guidewire or IVUS measurements (Agostoni et al, 2008;Lee et al, 2012;Meerkin et al, 2010;Neubauer et al, 2010).…”

Despite continuous progress in X-ray angiography systems, X-ray coronary angiography is fundamentally limited by its 2D representation of moving coronary arterial trees, which can negatively impact assessment of coronary artery disease and guidance of percutaneous coronary intervention. To provide clinicians with 3D/3D+time information of coronary arteries, methods computing reconstructions of coronary arteries from X-ray angiography are required. Because of several aspects (e.g. cardiac and respiratory motion, type of X-ray system), reconstruction from X-ray coronary angiography has led to vast amount of research and it still remains as a challenging and dynamic research area. In this paper, we review the state-of-the-art approaches on reconstruction of high-contrast coronary arteries from X-ray angiography. We mainly focus on the theoretical features in model-based (modelling) and tomographic reconstruction of coronary arteries, and discuss the evaluation strategies. We also discuss the potential role of reconstructions in clinical decision making and interventional guidance, and highlight areas for future research.

“…Once the image is created, operators can manipulate the images by zooming in or rotating the image. This allows the operator to have a better understanding of coronary anatomy and could also help the operator find an optimal angle to image of a vessel for an intervention (Dvir et al, 2005;Agostoni et al, 2008). An example of coronary after reconstructed with CardiOp-B system is shown in figure 1.…”
