A 58-year-old man with a history of hypertension presented with accelerating angina. Transthoracic echocardiography revealed a thickened aortic valve with pressure gradients and an estimated aortic valve area suggestive of mild aortic stenosis. Left heart catheterization demonstrated non-significant coronary artery disease. Pressure tracings showed a high left ventricular pressure and a mean gradient across the aortic valve of 69 mmHg. Subsequent transesophageal echocardiography revealed a subvalvular aortic stenosis that was secondary to the subaortic membrane, with severe valvular aortic stenosis...

In Europe, mitral regurgitation (MR) is the second most common form of valvular heart disease requiring surgical treatment. The case is presented of a 36-year-old woman with end-stage heart failure secondary to chemotherapy-induced cardiotoxicity, complicated by severe MR. She was listed for heart transplantation and underwent percutaneous MitraClip® implantation in order to preclude further clinical deterioration while awaiting a suitable donor. The one-year follow-up showed a strong improvement of symptoms and mostly reverse left ventricular remodelling, with consequent removal from the heart transplantation list...

Clinical trials using stem cell therapy for heart diseases have not reproduced the initial positive results obtained with animal models. This might be explained by a decreased regenerative capacity of stem cells collected from the patients. This work aimed at the simultaneous investigation of endothelial stem/progenitor cells (EPCs), mesenchymal stem/progenitor cells (MSCs), and hematopoietic stem/progenitor cells (HSCs) in sternal bone marrow samples of patients with ischemic or valvular heart disease, using flow cytometry and colony assays...

Calcific aortic stenosis (AS) is the most common form of valvular heart disease in Europe and North America. It is a progressive disease with a prolonged period of asymptomatic latency which eventually leads to critical left ventricular outflow tract obstruction necessitating surgical replacement of the valve. Statins are lipid-lowering drugs with a robust evidence base demonstrating clinical benefit in atherosclerotic coronary artery disease. There has therefore been significant interest in the potential benefit of statins in AS...

BACKGROUND: Valvular heart disease is highly prevalent in industrialized countries. Chronic use of anorexigens, amphetamine or ergot derivatives targeting the serotonin system has been associated with valvular heart disease. PURPOSE AND EXPERIMENTAL APPROACH: Here, we investigated the contribution of serotonin receptors in a mouse model of valve degeneration induced by nordexfenfluramine, the main metabolite of the anorexigens dexfenfluramine and benfluorex. KEY RESULTS: Chronically activated 5-HT2B receptors by nordexfenfluramine in mice mimicked early steps of mitral valve remodelling attested by increased valve thickness, and cell density in a thick extracellular matrix...

Myxomatous mitral valve disease (MMVD) is functionally and histologically identical to mitral valve prolapse (MVP) in humans. Currently, there are no medical treatments that can delay the progression of this valvular disease or associated cardiac remodelling. Therefore, there is a need to understand the molecular pathology associated with MMVD and MVP better, and thus identify potential therapeutic targets. Circulating exosomes contain small RNA, including miRNA, which reflect cell physiology and pathology...

BACKGROUND: Early reports suggest the number of cardiac intensive care unit (CICU) patients with primary noncardiac diagnoses is rising in the United States, but no national data currently exist. We examined changes in primary noncardiac diagnoses among elderly patients admitted to a CICU during the past decade. METHODS AND RESULTS: Using 2003 to 2013 Medicare data, we grouped elderly patients admitted to CICUs into 2 categories based on principal diagnosis at discharge: (1) primary noncardiac diagnoses and (2) primary cardiac diagnoses...

Valvular heart disease in women of childbearing age poses an increased risk of adverse maternal and fetal outcomes, and management in pregnancy can be challenging. Ideally, patients with suspected valvular disease should have preconception counseling by a multidisciplinary team including cardiologists with expertise in pregnancy and a maternal-fetal medicine specialist. Preconception planning should include a cardiac assessment of maternal risk, determination of frequency of surveillance, and a cardiovascular management plan during delivery...

BACKGROUND: Epicardial fat tissue has unique endocrine and paracrine functions that affect the cardiac autonomic system. The head-up tilt test (HUTT) is a simple non-invasive measurement that assesses autonomic nervous system dysfunction. We investigated the association between epicardial fat thickness (EFT) and autonomic neural tone, such as vagal tone. METHODS: A total of 797 consecutive patients (mean age 46.5 years, male: 45.7%) who underwent HUTT and echocardiography between March 2006 and June 2015 were enrolled...

First described in the early 1980s, antiphospholipid syndrome (APS) is a unique form of acquired autoimmune thrombophilia in which patients present with clinical features of recurrent thrombosis and pregnancy morbidity and persistently test positive for the presence of antiphospholipid antibodies (aPL). At least one clinical (vascular thrombosis or pregnancy morbidity) and one lab-based (positive test result for lupus anticoagulant, anticardiolipin antibodies and/or anti-β2-glycoprotein 1 antibodies) criterion have to be met for a patient to be classified as having APS...

Mitral regurgitation is one of the more common forms of valvular heart disease. Given the expansion of therapies for structural heart disease, new therapies for mitral regurgitation are emerging. An accurate description and classification of mitral disease is important to understand pathology and provide recommendations for therapy. Areas covered: In the modern evaluation of mitral regurgitation, 3-dimensional echocardiography (3DE) and cardiac magnetic resonance imaging (CMR) play important roles which overcome the prior limitations of 2-dimensional echocardiography...

Current research on valvular heart repair has focused on tissue-engineered heart valves (TEHV) because of its potential to grow similarly to native heart valves. Decellularized xenografts are a promising solution; however, host recellularization remains challenging. In this study, decellularized porcine aortic valves were implanted into the right ventricular outflow tract (RVOT) of sheep to investigate recellularization potential. Porcine aortic valves, decellularized with sodium dodecyl sulfate (SDS), were sterilized by supercritical carbon dioxide (scCO2) and implanted into the RVOT of five juvenile polypay sheep for 5 months (n = 5)...
