Western diet (WD), rich in saturated fat and sugars, has become a risk factor for obesity and metabolic syndrome, however, its effect on endothelial function and vascular remodeling is not fully elucidated. Recent evidence suggests cross-talk between Rho kinase (ROCK) pathway and cardiovascular system. We aimed to investigate the effect of WD on aortic remodeling and the contribution of ROCK signaling. Eight week old male Sprague-Dawley rats were fed either standard chow diet (SD) or high fructose/ high-fat diet, typically as in WD...

Coarctation of the aorta has been associated with increased thoracic aortic stiffness in adolescents and young adults. However, the effects of different therapeutic strategies on aortic stiffness in a young population is unknown. This study aimed to non-invasively assess aortic stiffness between different repair or intervention strategies in patients with coarctation of the aorta. Forty-nine coarctation patients who underwent either surgery (n = 26), balloon angioplasty (n = 14), or stent implantation (n = 12), and 26 age- and size-matched normotensive healthy controls underwent evaluation of thoracic aortic stiffness and flow hemodynamics via phase-contrast cardiac magnetic resonance...

INTRODUCTION: The usefulness of carbon dioxide (CO2 ) gas digital subtraction angiography (DSA) has been reported for patients with renal insufficiency and allergy to iodinated contrast agents. However, CO2 gas cannot replace the iodinated contrast agent in all cases owing to some disadvantages. We describe balloon-occluded CO2 DSA (B-CO2 DSA) as an improved CO2 DSA procedure for interventions in the internal iliac artery (IIA) region and compare the quality of images obtained using conventional CO2 DSA and B-CO2 DSA...

Acute aortic dissection is a life-threatening clinical emergency, which mostly occurs in aged patients and presents with sharp chest pain. In this paper, we reported a case of acute aortic dissection, which induced septic shock in a young woman, without typical chest pain. The septic shock was possibly due to the bacterial translocation caused by aortic dissection-induced intestinal ischemia and intestinal epithelial barrier dysfunction. Our case appeared as the first case report of aortic dissection presenting as septic shock...

Freeman-Sheldon syndrome (FSS) or "whistling face" syndrome is a rare congenital disorder complicated by characteristic facial deformities and muscular contractures. We report on a 64-year-old male patient presenting for surgical replacement of his aortic valve and review the available literature on anesthetic considerations and perioperative management principles. FSS frequently poses a significant challenge to airway management and gaining vascular access. Moreover, these patients are reportedly at risk for developing malignant hyperthermia (MH) or neuroleptic malignant syndrome...

QiShenYiQi dripping pills (QSYQ), a traditional Chinese medicine, are commonly used to treat coronary heart disease, and QSYQ was recently approved as a complementary treatment for ischemic heart failure in China. However, only few studies reported on whether QSYQ exerts a protective effect on heart failure induced by pressure overload. In this study, we explored the role of QSYQ in a mouse model of heart failure induced by transverse aortic constriction (TAC). Twenty-eight C57BL/6J mice were divided into four groups: Sham + NS group, Sham + QSYQ group, TAC + NS group, and TAC + QSYQ group...

Various clinical differences have been observed between patients with the FBN1 gene mutation and those with the classical Marfan phenotype. Although FBN1 knockout (KO) or dominant-negative mutant mice are widely used as an animal model for Marfan syndrome (MFS), these mice cannot recapitulate the genotype/phenotype relationship of Marfanoid-progeroid-lipodystrophy (MPL) syndrome, which is caused by a mutation in the C-terminus of fibrillin-1, the penultimate exon of the FBN1 gene. Here, we describe the generation of a rabbit MPL model with C-terminal truncation of fibrillin-1 using a CRISPR/Cas9 system...

Aortic dissection usually presents as an acute emergency and less commonly presents as chronic dissection. Two-dimensional and transoesophageal echocardiographic features of aortic dissection generally show dissection flap, dilated aorta and aortic regurgitation. We report a very unusual and extremely rare case of a 40-year-old female patient with chronic aortic dissection presenting as functional double aortic valve.

BACKGROUND: Cardiac magnetic resonance imaging (MRI) is considered the gold standard for assessment of left atrial (LA) volume. We assessed the feasibility of evaluating LA volume using 3D non-contrast computed tomography (NCCT). Furthermore, since manual tracing of LA volume is time consuming, we evaluated the accuracy of the LA area using 2D NCCT imaging for LA volume assessment. METHODS: MRI and NCCT imaging were performed in 69 patients before and one year after aortic valve replacement...

BACKGROUND: The current U.S. priority ranking for heart candidates is based on treatment intensity, not objective markers of severity of illness. This system may encourage centers to overtreat candidates. OBJECTIVES: This study sought to describe national variation in the intensity of treatment of adult heart transplantation candidates and identify center-level predictors of potential overtreatment. METHODS: The registrations of all U.S. adult heart transplantation candidates from 2010 to 2015 were collected from the SRTR (Scientific Registry of Transplant Recipients)...

BACKGROUND: Palliative repair of single ventricle defects involve a series of open-heart surgeries where a single-ventricle (Fontan) circulation is established. As the patient ages, this paradoxical circulation gradually fails, because of its high venous pressure levels. Reversal of the Fontan paradox requires an extra subpulmonic energy that can be provided through mechanical assist devices. The objective of this study was to evaluate the hemodynamic performance of a totally implantable integrated aortic-turbine venous-assist (iATVA) system, which does not need an external drive power and maintains low venous pressure chronically, for the Fontan circulation...

INTRODUCTION AND OBJECTIVES: Osteogenesis imperfecta (OI) is a connective tissue disease characterised by an anomalous synthesis of type i collagen. Little is known about the cardiovascular affectation suffered by these patients. The most frequently described are valvular dysfunction and dilatation of the aorta. We wanted to analyse the structural and functional changes of the heart in adult patients with OI. METHODS: We prospectively studied 82 patients with OI and compared them with 60 healthy subjects matched for age and sex...

Objective: To evaluate the early results of fenestrated endovascular aortic repair (FEVAR) using physician-modified stent grafts (PMSGs) for the treatment of patients with thoracoabdominal pathologies. Methods: Nineteen consecutive patients who underwent FEVAR using PMSGs between April 2012 and September 2017 were retrospectively reviewed. The modality of FEVAR technique was assessed, perioperative clinical data was recorded and the early results were evaluated. Results: Indications were thoracoabdominal aortic pathologies, including juxtarenal abdominal aortic aneurysm (JAAA) ( n =12), chronic thoracoabdominal aortic dissection with aneurysmal dilatation ( n =3), thoracoabdominal aortic aneurysm (TAAA) ( n =1), infrarenal AAA with an accessory renal artery in the segment of the aneurysmal neck ( n =2) and type Ⅰ endoleak after EVAR for AAA( n =1)...

Myocardial ischemia/reperfusion (I/R) injury is the major problem that aggravates cardiac damage. Several established animal models fail to explain the similarity in disease mechanism and progression as seen in humans; whereas guinea pig shows high similarity in cardiovascular parameters. Hence, current study is aimed to develop an animal model using guinea pigs that may best correlate with disease mechanism of human myocardial I/R injury. Male guinea pigs were randomized into three groups: normal diet (ND), high fat diet (HFD) and sham; fed with respective diets for 90 days...

Estrogen plays aprotective effect on the cardiovascular system. Abnormal vascular smooth muscle cells (VSMCs) are involvedin the progress of atherosclerosis. However, the effect of estrogen on VSMCs is still unclear. The purpose of this study is to investigate the effect of 17β-estradiol (E2), a potent endogeneous estrogen, on the development of atherosclerosis and its potential mechanisms. In vivo, the formation of atherosclerotic lesions and the extent of protein S-nitrosylation were compared between female and male apoE-/- mice to assess the effect of estrogen...
