Outcomes after One-Stage Repair of Coarctation of the Aorta and Combined Intracardiac Lesions in Infants

Abstract

Background:The aim of the study was to compare the outcomes of hypothermic circulatory arrest (GCA) and selective cerebral perfusion (SCP)

Comparison of hemodynamics in post-operation coarctation of aorta patients with different aortic arch geometry

“…Simulations were performed using a novel stabilized finite element method to solve the conservation of mass (continuity) and balance of fluid momentum (Navier-Stokes). Vessels were assumed as rigid and blood to be a Newtonian fluid with a density of 1.06 g/cm 3 and a viscosity coefficient of 0.004N/m 2 s. Computational meshes contained more than 4 million tetrahedral elements and localized refinement was performed. After that, files were put into Fluent 15.0 (Ansys, Canonsburg) for simulations for 3-5 cardiac cycles until the flow rate yielded periodic solutions.…”

“…1 With surgery or intervention treatment at an early age, patients usually have good prognosis of low mortality and normal cardiac function. [2][3][4] Unfortunately, long term morbidity for this population remains higher than normal population, due to the following complications: restenosis, aneurysm formation and hypertension. 5 Some researches have postulated that altered vascular structure would lead to hemodynamic changes and aggravate the damage of vascular wall, but the concrete mechanisms remain unclear.…”
