Dystrophic calcifications of the aortic valve may cause symptomatic aortic stenosis and account for a significant portion of patients who undergo elective valve replacement. Calcifications appearing grossly as a cloudy fluid surrounding the aortic valve leaflets are an uncommon finding. Normally, calcified aortic valves are characterised by large, nodular masses within the aortic cusps. We report a case of dystrophic calcifications on a stenotic aortic valve encountered intraoperatively, which was suggestive of infective endocarditis and abscess formation...

OBJECTIVE: Lp(a) [lipoprotein (a)] is composed of apoB (apolipoprotein B) and apo(a) [apolipoprotein (a)] and is an independent risk factor for cardiovascular disease and aortic stenosis. In clinical trials, anacetrapib, a CETP (cholesteryl ester transfer protein) inhibitor, causes significant reductions in plasma Lp(a) levels. We conducted an exploratory study to examine the mechanism for Lp(a) lowering by anacetrapib. APPROACH AND RESULTS: We enrolled 39 participants in a fixed-sequence, double-blind study of the effects of anacetrapib on the metabolism of apoB and high-density lipoproteins...

Patients with inoperable, high-risk, and intermediate-risk aortic stenosis can now be treated with transcatheter aortic valve replacement. Centers for Medicare and Medicaid Services and the Food and Drug Administration selectively choose centers based on experience and require a collaborative, multidisciplinary team approach in the treatment and decision making for these patients. The work-up has been streamlined. Gated multislice computed tomography angiogram has emerged as the gold standard for assessment of valve anatomy and sizing of the transcatheter heart valve...

The article deals with the problems of acquired valvular disorders. It mainly focuses on the new findings regarding ethiopathogenesis, diagnostics, evaluation and treatment, especially catheterization. In advanced countries, post-rheumatic abnormalities have almost disappeared, their current etiology has substantially changed (mitral stenosis). The earlier relatively rare degenerative changes now predominate, mainly affecting older patients (aortic stenosis). Also the treatment methods for acquired abnormalities have substantially changed - currently catheterization approaches are used more frequently in their correction...

BACKGROUND AND PURPOSE: Ticagrelor is an effective antiplatelet therapy among patients with atherosclerotic disease and, therefore, could be more effective than aspirin in preventing recurrent stroke and cardiovascular events among patients with embolic stroke of unknown source (ESUS), which includes patients with ipsilateral stenosis <50% and aortic arch atherosclerosis. METHODS: We randomized 13 199 patients with a noncardioembolic, nonsevere ischemic stroke or high-risk transient ischemic attack to ticagrelor (180 mg loading dose on day 1 followed by 90 mg twice daily for days 2-90) or aspirin (300 mg on day 1 followed by 100 mg daily for days 2-90) within 24 hours of symptom onset...

Thrombospondins (TSPs) represent extracellular matrix (ECM) proteins belonging to the TSP family that comprises five members. All TSPs have a complex multidomain structure that permits the interaction with various partners including other ECM proteins, cytokines, receptors, growth factors, etc. Among TSPs, TSP1, TSP2, and TSP4 are the most studied and functionally tested. TSP1 possesses anti-angiogenic activity and is able to activate transforming growth factor (TGF)-β, a potent profibrotic and anti-inflammatory factor...

In patients with severe aortic stenosis (AS), the presence of pulmonary hypertension (PH) has been linked to a poor prognosis. We aimed to assess the main determinants of PH in patients with severe AS and preserved left ventricular ejection fraction (LVEF). We prospectively enrolled 108 consecutive patients with isolated severe AS (indexed aortic valve area <0.6 cm(2)/m(2)) and LVEF >50%, in sinus rhythm. Left atrial (LA) function was assessed using longitudinal deformation parameters (by speckle tracking echocardiography)...

BACKGROUND: In this study, we sought to investigate the 2-year prognostic impact of B-type natriuretic peptide (BNP) levels at discharge, following transcatheter aortic valve replacement. METHODS AND RESULTS: We enrolled 1094 consecutive patients who underwent transcatheter aortic valve replacement between 2013 and 2016. Study patients were stratified into 2 groups according to survival classification and regression tree analysis (high versus low BNP groups). We evaluated the impact of high BNP on 2-year mortality compared with that of low BNP using a multivariable Cox model, and assessed whether this stratification would improve predictive accuracy for determining 2-year mortality by assessing time-dependent net reclassification improvement and integrated discrimination improvement...

Alkaptonuric ochronosis is a rare cause of aortic valve stenosis. We report the case of a 61-year-old female patient with alkaptonuria who presented to our institute with the clinical picture of severe aortic valve stenosis, which was confirmed by transthoracic echocardiography. On aortotomy, she was noted to have an impressive black discoloration of ascending aorta and the aortic root complex involving the aortic valve leaflets. She underwent an uneventful aortic valve replacement. She was discharged home 10 days postoperatively...
