BACKGROUND: Patients with degenerative aortic stenosis (AS) referred for transcatheter aortic valve implantation (TAVI) typically have advanced cardiac and vascular adverse remodeling and multiple comorbidities and, therefore, might not recover a normal functional capacity after valve replacement. We sought to investigate the prevalence, the predictors, and the prognostic impact of residual impairment of functional capacity after TAVI. METHODS AND RESULTS: Out of 790 patients undergoing TAVI with impaired functional capacity (NYHA II-IV) at baseline, NYHA functional class improved in 592 (86...

Primary hypothyroidism related to morphological and volumetric abnormalities of the thyroid gland is one of the commonest of several endocrine dysfunctions in Williams-Beuren syndrome (WBS). We report a 10-month-old boy with WBS who presented with central hypothyroidism. During the neonatal period, he had prolonged jaundice, feeding difficulties and episodes of colic that continued during early infancy. Additionally, there was slowing of growth and mild developmental delay. He underwent surgical repair for supravalvular aortic stenosis at 6 months of age...

Patients with symptomatic carotid artery disease should be managed by a multidisciplinary team including neurologists, vascular surgeons and interventionalists. Duplex ultrasound is the most widely used diagnostic modality to assess carotid disease, followed by additional imaging tests (CT- or MR-angiography) to confirm the severity of the stenosis, detect brain lesions, and assess intracranial circulation as well as the supra-aortic anatomy. Although overall randomized trial results favored (CEA) over carotid artery stenting (CAS) in symptomatic patients, this was likely related to the insufficient expertise of the endovascular specialists in several of the trials...

Objective: Undiagnosed critical congenital heart disease (CCHD) was assessed before discharge from maternity hospital.Basic information was provided for screening CCHD in the early neonatal stage.Chi-squared test was used for comparison of categorical variables(detection rate of different types of CCHD). Method: A retrospective cohort study was conducted in neonates with CCHD who were admitted to Children's Hospital of Fudan University between 1 January 2012 and 31 December 2015. For comparing with the previously reported undiagnosed rate of CCHD at discharge, CCHD was defined as all duct dependent congenital heart disease (DDCHD) and any cyanotic CHD that required early surgery...

An 84-year-old man with symptomatic severe aortic stenosis received transcatheter aortic valve implantation (TAVI). Dual-antiplatelet therapy was continued for 6 months post TAVI, and aspirin alone was used thereafter. Four-dimensional multidetector computed tomography revealed a new hypoattenuated leaflet thickening (HALT) with reduced leaflet motion at 1 year, considered to indicate leaflet thrombosis. At the 2-year follow-up, leaflet mobility had improved, with spontaneous regression of HALT. This is the first report of confirmed spontaneous regression of possible transcatheter heart valve thrombosis and recovery of leaflet mobility without the need for additional anticoagulant...

OBJECTIVES: To investigate the feasibility and image quality of low-dose contrast computed tomography (CT) angiography with pulmonary artery (PA) protocol. BACKGROUND: Aortic stenosis is the most common valvular heart disease and transcatheter aortic valve replacement (TAVR) has evolved as an alternative method for surgical valve replacement in intermediate-risk and high-risk surgical patients. CT is essential for measurement of aortic annulus prior to TAVR. METHODS: Twenty patients underwent a low-dose contrast study with PA protocol and 20 patients underwent a traditional-dose study (traditional protocol)...

BACKGROUND: The operation of aortic valve replacement (AVR) after CABG is a technically challenging procedure in respect to dissection of living grafts from its surrounding tissue, myocardial protection, and so on, especially that procedure to patients with living in situ functional arterial grafts to occluded native coronary arteries has a special problem in regard to myocardial protection because myocardial blood supply originates from various arteries including the left internal thoracic artery (LITA), the right internal thoracic artery (RITA), and the right gastroepiploic artery (GEA); hence, adequate myocardial protection should be fastidiously considered...

BACKGROUND: Calcific aortic stenosis (CAS) is the most common heart valve disease in the elderly, representing an important economic and social burden in developed countries. Currently, there is no way to predict either the onset or progression of CAS, emphasizing the need to identify useful biomarkers for this condition. METHODS: We performed a multi-proteomic analysis on different kinds of samples from CAS patients and healthy donors: tissue, secretome and plasma...

AIMS: The impact of pulmonary hypertension (PH) on in-hospital outcome of either surgical (SAVR) or transcatheter aortic valve replacement (TAVR) was analyzed. METHODS AND RESULTS: Data from all 107,057 patients undergoing isolated SAVR or TAVR in Germany between 2007 and 2014 was provided by the German Federal Bureau of Statistics. About 18% of patients with aortic valve stenosis suffered from PH. Patients with PH had more co- morbidities with consequently increased EuroSCORE (TAVR without PH: 12...

Bicuspid aortic valve (BAV) disease has a male predominance of approximately 3:1 and shows diverse presentations about aortic valve dysfunction. This study aimed to find independent determinants for significant aortic stenosis (AS) or significant aortic regurgitation (AR) in adults with BAV. We retrospectively investigated the medical records of 1,073 subjects (773 men, mean age 55 ± 14 years) who were first diagnosed with BAV disease by transthoracic echocardiography. We excluded 52 subjects with both significant AS and significant AR...

Haemodynamic perturbations such as flow recirculation zones play a key role in progression and development of renal artery stenosis, which typically originate at the aorta-renal bifurcation. The spiral nature of aortic blood flow, division of aortic blood flow in renal artery as well as the exercise conditions have been shown to alter the haemodynamics in both positive and negative ways. This study focuses on the combinative effects of spiral component of blood flow, renal-to-aorta flow ratio and the exercise conditions on the size and distribution of recirculation zones in renal branches using computational fluid dynamics technique...

The emergence of the global pandemic of chronic diseases necessitates critical assessment of interventions that can be targeted at both the individual and population levels. Among cardiovascular diseases, the increasing prevalence of valvular heart diseases such as aortic stenosis parallels the rising burden of atherosclerotic cardiovascular diseases. As an alternative to surgical aortic valve replacement, technological innovation has allowed development of minimally invasive transcatheter aortic valve replacement (TAVR)...

China and India are the 2 fastest growing major world economies. However, they suffer from great differences in health policies, demographics, and rates of population growth. Whereas China has seen a steep decline in rheumatic heart disease (RHD) and a rise in life expectancy, India continues to suffer from a significant burden of RHD due to insufficient distribution of economic prosperity to health care, denser population, and ineffective application of World Health Organization RHD prevention guidelines. As China faces the burden of the world's largest geriatric population, focus has shifted to calcific aortic stenosis for which it prepares by expansions in the field of transcatheter aortic valve replacement...

OBJECTIVE: Transitions in the spectrum of valvular heart diseases (VHDs) in developed countries over the 20th century have been reported from clinical case series, but large, contemporary population-based studies are lacking. METHODS: We used nationwide registers to identify all patients with a first diagnosis of VHD at Swedish hospitals between 2003 and 2010. Age-stratified and sex-stratified incidence of each VHD and adjusted comorbidity profiles were assessed...

The mainstay for the current treatment of severe aortic stenosis includes surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI). In patients with high operative risk TAVI is established as first line therapy. New data on intermediate and low risk groups demonstrate at least non-inferiority of TAVI against SAVR, and in the near future a consistently rising number of transcatheter procedures may be anticipated. The purpose of this review is to outline the decision making process, hence to illustrate the diagnostic algorithm and to provide criteria for a differentiated approach against the background of recent data...

Calcium content in patients with calcific aortic valve disease (CAVD) correlates with the severity of stenosis. In CAVD, activated T lymphocytes localize with osteoclast regions; however, the functional consequences of this association remain unknown. We hypothesized that CD8(+) T cells modulate calcification in CAVD. Explanted CAVD valves (n = 52) dissected into noncalcified and calcified portions were subjected to mRNA extraction, real-time quantitative PCR, enzyme-linked immunosorbent assay, and immunohistochemical analyses...
