Influence of Freezing Temperature During Irradiation on the Biomechanical Properties of Irradiated Frozen Cortical Allograft
<p>Gamma irradiation minimizes the risk of infectious disease transmission and is the terminal sterilization method of choice for human cortical allografts. Its application is simple, and its results are reliable. Its more prominent indirect effect is strongly influenced by three main factors - the presence of oxygen, water and by temperature. There are, however, enduring concerns regarding its undesired adverse effects on the biomechanical properties of bone allografts. Even so, the available literature mentioning these effects had conflicting conclusions especially pertaining to the effect of temperature during the irradiation process. The purpose of this study was to examine the influence of freezing temperatures during gamma irradiation on the biomechanical properties of human cortical allografts. Five mid shaft femurs from cadaveric donors were cut into bone cubes measuring 4mm3. Each cube was assigned to one of 3 experimental groups. The first group was subjected to gamma irradiation at deep-freezing temperatures below -40°C (the Radiated in Dry ice / RD group), i.e. the recommended temperature for long-term storage of bone allografts. The second group was subjected to irradiation within a freezing temperature range of -40°C to 0°C (the Radiated in Gel ice / RG group) whilst the last group, acting as control (C group), did not receive irradiation treatment. Irradiation dose was set between 25 and 35 kGy. All samples were subsequently subjected to compressive load to failure to determine their biomechanical properties. Allografts irradiated at a higher freezing temperature range (RG, -40°C to 0°C) were observed to have a significantly lower yield point, ultimate tensile strength, resilience and toughness in comparison to those which were not irradiated (Control) and those irradiated at deep freezing temperatures (RD, below -40°C). The above four parameters of the Control and RD group samples were comparable. No difference in the Young’s modulus parameter was observed in all three groups. The results suggest that irradiation at deep freezing temperatures confers protection to the biomechanical properties of cortical femoral allografts, which may be the result of the complete immobilization of water molecules when deep frozen. With its inability to participate in the formation of free radicals via its radiolysis in the frozen state, the deleterious effects of radiation on collagen architecture are hence attenuated. The apparent loss of this protective effect when a higher freezing temperature range was employed during irradiation was substantiated.</p>

<p>Data set from Marrocco-Trischitta MM, Romarowski RM, de Beaufort HW, Conti M, Vitale R, Secchi F, Auricchio F, Trimarchi S. The Modified Arch Landing Areas Nomenclature identifies hostile zones for endograft deployment: a confirmatory biomechanical study in patients treated by thoracic endovascular aortic repair†. Eur J Cardiothorac Surg. 2019 May 1;55(5):990-997. doi: 10.1093/ejcts/ezy409. PMID: 30535119.</p> <p> </p> <p>This is the abstract:</p> <p><strong>Objectives: </strong>Our goal was to confirm whether the Modified Arch Landing Areas Nomenclature (MALAN) for thoracic endovascular aortic repair, in which each landing area is described by indicating both the proximal landing zone (PLZ) and the type of arch (e.g. 0/I), identifies unfavourable landing zones for endograft deployment in diseased aortas.</p> <p><strong>Methods: </strong>Preoperative computed tomography angiography scans of 10 patients scheduled for thoracic endovascular aortic repair for aneurysm or penetrating ulcer of the arch and with a potential hostile PLZ were reviewed. Five had proximal deployment planned in MALAN area 3/III and 5, in MALAN area 2/III. The angulation of each PLZ was calculated. Computational fluid dynamics modelling was used to compute magnitude and orientation of pulsatile displacement forces in each PLZ. Normalized values based on PLZ areas (i.e. equivalent surface traction) were calculated. Results were compared to those obtained in healthy controls stratified by the MALAN.</p> <p><strong>Results: </strong>Angulation was severe (>60°) in MALAN areas 3/III and 2/III, which was consistent with the findings obtained in healthy controls. Increased magnitude (P = 0.021) and unfavourable orientation (i.e. orthogonal to the longitudinal aortic axis) of equivalent surface traction (P = 0.011) was also found in these areas compared to the adjacent ones, following the same pattern seen in the controls. Adverse events related to proximal endograft performance were reported in 3/10 cases.</p> <p><strong>Conclusions: </strong>This study confirms in diseased aortas initial proof-of-concept findings on the predictive value of the MALAN to identify landing areas with a geometric and haemodynamic environment hostile for thoracic endovascular aortic repair. These adverse biomechanical features may entail an increased risk of dismal endograft performance.</p> <p> </p> <p> </p>

Epub ahead of print. PMID: 32804291.</p> <p> </p> <p>This is the abstract:</p> <p>Congenital bicuspid aortic valve (BAV) consists of two fused cusps and represents a major risk factor for calcific valvular stenosis. Herein, a fully coupled fluid-structure interaction (FSI) BAV model was developed from patient-specific magnetic resonance imaging (MRI) and compared against in vivo 4-dimensional flow MRI (4D Flow). FSI simulation compared well with 4D Flow, confirming direction and magnitude of the flow jet impinging onto the aortic wall as well as location and extension of secondary flows and vortices developing at systole: the systolic flow jet originating from an elliptical 1.6 cm<sup>2</sup> orifice reached a peak velocity of 252.2 cm/s, 0.6% lower than 4D Flow, progressively impinging on the ascending aorta convexity. The FSI model predicted a peak flow rate of 22.4 L/min, 6.7% higher than 4D Flow, and provided BAV leaflets mechanical and flow-induced shear stresses, not directly attainable from MRI. At systole, the ventricular side of the non-fused leaflet revealed the highest wall shear stress (WSS) average magnitude, up to 14.6 Pa along the free margin, with WSS progressively decreasing towards the belly. During diastole, the aortic side of the fused leaflet exhibited the highest diastolic maximum principal stress, up to 322 kPa within the attachment region. Systematic comparison with ground-truth non-invasive MRI can improve the computational model ability to reproduce native BAV hemodynamics and biomechanical response more realistically, and shed light on their role in BAV patients' risk for developing complications; this approach may further contribute to the validation of advanced FSI simulations designed to assess BAV biomechanics.</p> <p> </p>
