Riociguat attenuates left ventricular proteome and microRNA profile changes after experimental aortic stenosis in mice.

Br J Pharmacol 2022 Jun 25. Epub 2022 Jun 25.

German Centre for Cardiovascular Research (DZHK), Greifswald, Germany.

Background And Purpose: Development and progression of heart failure (HF) involve endothelial and myocardial dysfunction as well as a dysregulation of the nitric oxide - soluble guanylyl cyclase - cyclic guanosine monophosphate (NO-sGC-cGMP) signalling pathway. Recently, we reported that the sGC stimulator riociguat (RIO) has beneficial effects on cardiac remodelling and progression of HF in response to chronic pressure overload. Here, we examined if these favourable RIO effects are also reflected in alterations of the myocardial proteome and microRNA profiles. Read More

Controlled Comparison of Simulated Hemodynamics Across Tricuspid and Bicuspid Aortic Valves.

Ann Biomed Eng 2022 Jun 24. Epub 2022 Jun 24.

Institute for Computational & Mathematical Engineering, Stanford University, Stanford, CA, USA.

Bicuspid aortic valve is the most common congenital heart defect, affecting 1-2% of the global population. Patients with bicuspid valves frequently develop dilation and aneurysms of the ascending aorta. Both hemodynamic and genetic factors are believed to contribute to dilation, yet the precise mechanism underlying this progression remains under debate. Read More

TAVR for severe aortic stenosis and papillary fibroelastoma in a high-risk setting.

Br J Cardiol 2021 22;28(2):23. Epub 2021 Apr 22.

Cardiac Surgeon, and Division Head, Division of Cardiac Surgery St. Michael's Hospital and Li Ka Shing Knowledge Institute, University of Toronto, Toronto, Ontario, M5B 1W8, Canada.

Papillary fibroelastomas (PFE) are rare benign cardiac tumours mainly originating on aortic and mitral valvular surfaces. Management is individualised, but most recommend surgical excision due to thromboembolic risk. We report a 75-year-old man with symptomatic severe aortic stenosis compounded by PFE. Read More

Left Atrial Appendage Amputation for Atrial Fibrillation during Aortic Valve Replacement.

J Clin Med 2022 Jun 14;11(12). Epub 2022 Jun 14.

Department of Cardiac Surgery, Klinikum Nürnberg, Paracelsus Medical University Nuremberg, 90471 Nuremberg, Germany.

Background: Occluding the left atrial appendage (LAA) during cardiac surgery reduces the risk of ischemic stroke; nonetheless, it is currently only softly recommended with "may be considered" by the current guidelines. We aimed to assess thromboembolic risk after LAA amputation in patients with atrial fibrillation (AF) and aortic stenosis undergoing biological aortic valve replacement (AVR) as primary cardiac surgery.

Methods: Two cohorts were generated retrospectively: patients with AF undergoing AVR alone or combined with revascularization either with LAA amputation or without. Read More

Implication of Lipids in Calcified Aortic Valve Pathogenesis: Why Did Statins Fail?

J Clin Med 2022 Jun 10;11(12). Epub 2022 Jun 10.

Department of Medicine, Division of Nephrology, The Icahn School of Medicine at Mount Sinai, New York, NY 10029, USA.

Calcific Aortic Valve Disease (CAVD) is a fibrocalcific disease. Lipoproteins and oxidized phospholipids play a substantial role in CAVD; the level of Lp(a) has been shown to accelerate the progression of valve calcification. Indeed, oxidized phospholipids carried by Lp(a) into the aortic valve stimulate endothelial dysfunction and promote inflammation. Read More

Healthcare (Basel) 2022 May 24;10(6). Epub 2022 May 24.

LPRI, EMSI, Casablanca 23300, Morocco.

This paper targets a major challenge of how to effectively allocate medical resources in intensive care units (ICUs). We trained multiple regression models using the Medical Information Mart for Intensive Care III (MIMIC III) database recorded in the period between 2001 and 2012. The training and validation dataset included pneumonia, sepsis, congestive heart failure, hypotension, chest pain, coronary artery disease, fever, respiratory failure, acute coronary syndrome, shortness of breath, seizure and transient ischemic attack, and aortic stenosis patients' recorded data.

Ultrasonographic Assessment of Atherosclerotic Renal Artery Stenosis in Elderly Patients with Chronic Kidney Disease: An Italian Cohort Study.

Diagnostics (Basel) 2022 Jun 13;12(6). Epub 2022 Jun 13.

Department of Public Health, University of Naples Federico II, 80100 Naples, Italy.

Although atherosclerotic renal artery stenosis (ARAS) is strictly associated with high cardiovascular risk and mortality, it often may remain unrecognized being clinically silent and frequently masked by co-morbidities especially in elderly patients with coexisting chronic kidney disease (CKD). The present observational study was conducted in elderly CKD-patients with atherosclerosis on other arterial beds. The aims were assessment of (1) ARAS prevalence; (2) best predictor(s) of ARAS, using duplex ultrasound; and (3) cardiovascular and renal outcomes at one-year follow-up. Read More

College of Pharmacy and Natural Medicine Research Institute, Mokpo National University, 1666 Yeongsan-Ro, Cheonggye-Myeon, Muan-Gun 58554, Jeonnam, Korea.

Calcific aortic valve stenosis (CAVS) is the most prevalent heart valvular disease worldwide and a slowly progressive disorder characterized by thickening of the aortic valve, calcification, and subsequent heart failure. Valvular calcification is an active cell regulation process in which valvular interstitial cells involve phenotypic conversion into osteoblasts/chondrocytes-like cells. The underlying pathophysiology is complicated, and there have been no pharmacological treatments for CAVS to date. Read More

Serum and Vascular Stiffness Biomarkers Associated with the Severity of Degenerative Aortic Valve Stenosis and Cardiovascular Outcomes.

J Cardiovasc Dev Dis 2022 Jun 17;9(6). Epub 2022 Jun 17.

Department of Interventional Cardiology, The John Paul II Hospital, Prądnicka 80, 31-202 Krakow, Poland.

Background: Although degenerative aortic valve stenosis (DAS) is the most prevalent growth-up congestive heart valve disease, still little known about relationships between DAS severity, vascular stiffness (VS), echocardiographic parameters, and serum biomarkers in patients undergoing transcatheter (TAVR) or surgical aortic valve replacement (SAVR). The objective of this study was to identify biomarkers associated with DAS severity, and those that are associated with cardiovascular death (CVD) and episodes of chronic heart failure (CHF) exacerbation.

Methods: A total of 137 patients with initially moderate-to-severe DAS were prospectively evaluated for the relationship between DAS severity, baseline VS, and serum biomarkers (uPAR, GDF-15, Gal-3, IL-6Rα, ET-1, PCSK9, RANTES/CCL5, NT-proBNP, and hs-TnT), and were followed-up for 48 months.

Dissociation of early and late face-related processes in autism spectrum disorder and Williams syndrome.

Orphanet J Rare Dis 2022 Jun 22;17(1):244. Epub 2022 Jun 22.

Institut Des Sciences, Cognitives Marc Jeannerod, Centre National de La Recherche Scientifique, 67 boulevard Pinel, 69500, Bron, France.

Background: Williams syndrome (WS) and Autism Spectrum Disorders (ASD) are neurodevelopmental conditions associated with atypical but opposite face-to-face interactions patterns: WS patients overly stare at others, ASD individuals escape eye contact. Whether these behaviors result from dissociable visual processes within the occipito-temporal pathways is unknown. Using high-density electroencephalography, multivariate signal processing algorithms and a protocol designed to identify and extract evoked activities sensitive to facial cues, we investigated how WS (N = 14), ASD (N = 14) and neurotypical subjects (N = 14) decode the information content of a face stimulus.
