“…This finding is in agreement with X-ray coronary angiography data which found lower displacements occurring for the LAD when compared with the LCX. 53 Others have shown that the phasic relation between the flow rates and arterial wall dynamics caused by coronary wall motion significantly influences the temporal variations in wall shear stress and flow patterns 31,32,45,51 while the time-averaged wall shear stress was not appreciably affected. 51 This is in agreement with our findings for outlet flowrates, with no noticeable changes in time-averaged outlet flowrates for the LAD and LCX vessels.…”

The coronary arterial tree experiences large displacements due to the contraction and expansion of the cardiac muscle and may influence coronary haemodynamics and stent placement. The accurate measurement of catheter trackability forces within physiological relevant test systems is required for optimum catheter design. The effects of cardiac motion on coronary flowrates, pressure drops, and stent delivery has not been previously experimentally assessed. A cardiac simulator was designed and manufactured which replicates physiological coronary flowrates and cardiac motion within a patient-specific geometry. A motorized delivery system delivered a commercially available coronary stent system and monitored the trackability forces along three phantom patient-specific thin walled compliant coronary vessels supported by a dynamic cardiac phantom model. Pressure drop variation is more sensitive to cardiac motion than outlet flowrates. Maximum pressure drops varied from 7 to 49 mmHg for a stenosis % area reduction of 56 to 90%. There was a strong positive linear correlation of cumulative trackability force with the cumulative curvature. The maximum trackability forces and curvature ranged from 0.24 to 0.87 N and 0.06 to 0.22 mm(-1) respectively for all three vessels. There were maximum and average percentage differences in trackability forces of (23-49%) and (1.9-5.2%) respectively when comparing a static pressure case with the inclusion of pulsatile flow and cardiac motion. Cardiac motion with pulsatile flow significantly altered (p value <0.001) the trackability forces along the delivery pathways with high local percentage variations and pressure drop measurements.

“…A large absolute torsion correlates with the occurrence of vascular pathologies. Similar investigations of the torsion based on tomographic data are made for the coronary artery (Pao et al, 1992;Puentes et al, 1998;Medina et al, 2004;Zhenga and Qib, 2011;Strandmark et al, 2013) and for the superficial femoral arteries (Wood et al, 2006). The methodology in medical applications differs from that in other fields of application.…”

Curvature and torsion of three-dimensional curves are important quantities in fields like material science or biomedical engineering. Torsion has an exact definition in the continuous domain. However, in the discrete case most of the existing torsion evaluation methods lead to inaccurate values, especially for low resolution data. In this contribution we use the discrete points of space curves to determine the Fourier series coefficients which allow for representing the underlying continuous curve with Cesàro's mean. This representation of the curve suits for the estimation of curvature and torsion values with their classical continuous definition. In comparison with the literature, one major advantage of this approach is that no a priori knowledge about the shape of the cyclic curve parts approximating the discrete curves is required. Synthetic data, i.e., curves with known curvature and torsion, are used to quantify the inherent algorithm accuracy for torsion and curvature estimation. The algorithm is also tested on tomographic data of fiber structures and open foams, where discrete curves are extracted from the pore spaces.

“…Regarding the 3D reconstruction of vessel centerlines, various deformable models 10 – 12 and dynamic programming methods 8 , 13 , 14 are suggested to avoid the epipolar geometry problem when a curve’s point from one view intersects the corresponding centerline on other views more than once 15 . Obtaining a 3D vessel surface from its 2D projections remains a nontrivial task.…”

“…Reconstructing a sequence of XRA frames requires finding the correspondence between the frames acquired from different viewpoints, which is commonly addressed by using ECG-gating or by using a bi-plane XRA device. Beside using additional in-plane compensation of complex cardiac motions 21 , recent studies have assumed that a referent static 3D reconstruction is performed from the corresponding frames and then CA is tracked over time 13 , 14 . The second approach independently reconstructed CA sequences and then used various algorithms for temporal matching of the CA tree – for example, starting from the time-point with the least global motion 19 .…”

Despite its two-dimensional nature, X-ray angiography (XRA) has served as the gold standard imaging technique in the interventional cardiology for over five decades. Accordingly, demands for tools that could increase efficiency of the XRA procedure for the quantitative analysis of coronary arteries (CA) are constantly increasing. The aim of this study was to propose a novel procedure for three-dimensional modeling of CA from uncalibrated XRA projections. A comprehensive mathematical model of the image formation was developed and used with a robust genetic algorithm optimizer to determine the calibration parameters across XRA views. The frames correspondences between XRA acquisitions were found using a partial-matching approach. Using the same matching method, an efficient procedure for vessel centerline reconstruction was developed. Finally, the problem of meshing complex CA trees was simplified to independent reconstruction and meshing of connected branches using the proposed nonuniform rational B-spline (NURBS)-based method. Because it enables structured quadrilateral and hexahedral meshing, our method is suitable for the subsequent computational modelling of CA physiology (i.e. coronary blood flow, fractional flow reverse, virtual stenting and plaque progression). Extensive validations using digital, physical, and clinical datasets showed competitive performances and potential for further application on a wider scale.
