“…CoA is a common congenital heart anomaly that frequently affects males more than females and usually manifests in childhood. In adults, CoA is uncommon and most commonly represents cases of recoarctation after surgical repair or rarely missed native coarctation [3]. The natural history of untreated CoA is the development of refractory hypertension, dissection/rupture of the aorta, aortic endarteritis, premature CAD and CHF.…”

“…Bartoccioni et al [11], reported a similar case of a 55-year-old woman with CoA associated with aortic valve stenosis and ischemic cardiomyopathy who was managed by a single-stage surgical approach of these pathologies. Another case was described by Novosel et al [3] of an elderly woman with aortic coarctation combined with aortic valve stenosis and mitral regurgitation who underwent a two-stage approach that combined a surgical correction of intracardiac pathologies in the first stage, followed by repair of the aortic coarctation by percutaneous placement of an Advanta V12 large-diameter stent graft.…”

To the best of our knowledge, there have not been any reports of total transcatheter approach including stenting of severe coarctation of the aorta (CoA), transcatheter aortic valve replacement (TAVR) for concomitant severe aortic valve stenosis, and percutaneous coronary intervention (PCI) to treat significant coronary artery disease in a single patient. We report a 70-year-old female, who presented with uncontrolled hypertension and acute decompensated heart failure (ADHF) and was found to have severe CoA, severe bicuspid aortic valve (BAV) stenosis, and significant proximal left anterior descending (LAD) coronary artery disease. In a multidisciplinary heart team meeting, we decided to perform an endovascular repair of both cardiac and vascular pathologies using a two-stage approach due to the significant comorbidities; mainly uncontrolled hypertension, type 2 diabetes mellitus, chronic obstructive pulmonary disease, and severe calcifications of the ascending aorta. The procedures were successfully performed and the patient was asymptomatic 30 months later at follow-up and was without any significant gradients across the coarctation or the aortic valve.

“…The model should be simplified as much as possible on the premise of guarantee calculation precision, therefore those characteristics which do not affect the valve body overall performance can be simplified in the process of modeling. After ignore some unnecessary chamfering, parametric calculation model of gate valve is obtained as shown in Figure 1 [8][9][10].…”

Stress concentration zone and maximumdeformation zone ofgate valve at 1.6MPaworking pressure were found out according to strength calculationand analysisby ANSYSsoftware, which proceedsthe processes of modeling, meshing, constraintsdefine, applyingloadsand solving. Design variables,state variablesand optimize targetswere defined by target optimization design function of ANSYS Workbenchin ordertoreveal the influence law of eachdesign variable onthe gate valve body equivalent stress,and the optimal valuesof design variablescould be obtained after calculation. The valve structure was improved and stress concentration was reduced from the perspective of safety and economy,whichcouldprovidea referencefor reliable valvedesign.The shape of the valve body was optimized by topology optimization design in order to achieve the rational use of materials.Researchresultsshow that the maximum stress lies on both sides of the valve rib plateand the stress is beyond thematerial allowable value, but the valve body has little deformation.After optimization the maximum equivalent stress of valve body is decreasedby23.91%and the valvebodyhasuniformstress distribution, the mass of the valve body is reduced by1.4%as well. Material utilization is improvedeffectively,which indicates that the optimizationdesignbased onANSYS Workbenchis highly efficient and reliable.
