World Health Organization (WHO) group 1 pulmonary arterial hypertension (PAH) is a progressive, debilitating disease. Previous observational studies have demonstrated that artery denervation (PADN) reduces pressures in PAH. However, the safety and effectiveness of PADN not been established randomized trial. The aim this study was to determine treatment effects patients with Patients WHO PAH taking PAH-specific drugs for at least 30 days were enrolled multicenter, sham-controlled,...

Remodeling of right coronary artery (RCA) occurs during ventricular hypertrophy (RVH) induced by banding the pulmonary (PA). The effect RVH on RCA endothelial function and reactive oxygen species (ROS) in vessel wall remains unclear. A swine model (n = 12 pigs) PA was used to study ROS level. To obtain longitudinal hemodynamic geometric data, digital subtraction angiography progression RVH. Blood flow increased 82% lumen diameter 22% over a 4-wk period increase blood commensurate resulted...

Mortality during follow-up after acute Type B aortic dissection is substantial with expansion observed in over 59% of the patients. Lumen pressure differential considered a prime contributing factor for dilation propagation. The objective study was to evaluate relationship between changes vessel geometry and without lumen post propagation an ex vivo porcine model comparison patient clinical data. A pulse duplicator system utilized propagate within descending thoracic vessels set proximal...

The pressure-diameter relation (PDR) and the wall strain of coronary blood vessels have important implications for flow arthrosclerosis, respectively. Previous studies shown that these mechanical quantities are significantly affected by axial stretch vessels. objective this study was to measure physiological in vasculature; i.e., from left anterior descending (LAD) artery tree sinus vein determine its effect on PDR hence stiffness. Silicone elastomer perfused through LAD trees cast at...

This study aimed to assess the long-term effects of pulmonary artery denervation (PADN) on mortality in patients with arterial hypertension (PAH).Between March 2012 and 2018, a total 120 PAH, who underwent PADN treatment were prospectively followed up, analysed. Patients classified into World Health Organization (WHO) Functional Class I II (FC 1-2; n=46) III IV 3-4; n=74) according their FC prior PADN. The primary endpoint was lung transplantation-free until 2021. secondary change six-minute...

Abstract Aim: Inherent fundamental difference exists among arteries of different sizes. The purpose this study was to evaluate the relation between regional wall shear stress (WSS) in various sizes and contents nitrite NO synthase (NOS) isoforms. Methods: Five conduit a wide range diameter (1–8 mm) were examined hind limbs 13 pigs. Blood flow rate outer measured vivo determine WSS. Arterial tissues harvested for measurement NOS protein contents. concentration nitrite, product synthesis,...

This study evaluated the prognostic value of remnant lipoprotein cholesterol (RLP-C) as a predictor in-stent restenosis (ISR) after drug-eluting stent (DES) implantation in patients with coronary artery disease (CAD). Consecutive CAD (n = 612) who underwent both successful DES and follow-up angiography ranging from 6 to 24 months were enrolled. The independent predictors ISR explored by multivariate logistic regression analysis; 95 (15.52%) identified have ISR. Multivariate analysis showed...

The zero-stress state of a blood vessel has been extensively studied because it is the reference for which all calculations intramural stress and strain must be based. It also found to reflect nonuniformity in growth remodeling response chemical or physical changes. can characterized by an opening angle, defined as angle subtended two radii connecting midpoint inner wall. All prior studies documented with no regard duration no-load state. Our hypotheses were that, given viscoelastic...

The use of endovascular treatment in the thoracic aorta has revolutionized clinical approach treating Stanford type B aortic dissection. endograft procedure is a minimally invasive alternative to traditional surgery for management complicated type-B patients. Endograft first deployed exclude proximal entry tear redirect blood flow towards true lumen and then stent/graft push intimal flap against false wall such that reconstituted by sealing lumen. Although reduced mortality rate patients...

Thoracic endovascular aortic repair (TEVAR) has been widely adopted as a standard for treating complicated acute and high-risk uncomplicated Stanford Type-B dissections. The treatment redirects the blood flow towards true lumen by covering proximal dissection tear which promotes sealing of false lumen. Despite advances in TEVAR, over 30% patients require additional interventions. This is primarily due to presence persistent patent post-TEVAR that could potentially enlarge time. We propose...
