BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia. Valvular heart disease is a strong predictor, yet the underlying molecular mechanisms are unknown. OBJECTIVE: We sought to investigate the prevalence of somatic variants in AF candidate genes in an AF patient population undergoing surgery for mitral valve regurgitation (MVR) to determine whether these patients are genetically predisposed to AF. METHODS: DNA was extracted from blood and left atrial tissue from 44 AF patients with MVR...

OBJECTIVE: To describe a case of recurrent calcified cerebral emboli (CCE)-related acute ischemic stroke (AIS) and the diagnostic utility of plaque morphology characterization on carotid ultrasound. BACKGROUND: CCE are a rare cause of AIS. CCE-related AIS has been previously reported only in high vascular-risk patients such as those with severe carotid stenosis, widespread atheromatous disease, or cardiac valvular disease. CCE-related AIS from a carotid origin has not been reported in patients without carotid stenosis...

PURPOSE OF REVIEW: Survival after the Fontan procedure for palliation of single ventricle congenital heart disease has improved. However, adults with Fontan circulation are at risk for several complications including heart failure, thromboembolism, and protein-losing enteropathy. This review discusses the role of noninvasive imaging for surveillance and early detection of anatomic and functional abnormalities of the Fontan circulation that can impact the risk for Fontan failure over time...

Cardiac valvular disease as consequence of radiation and chemotherapy during treatment for malignancy is growing in its awareness. While the overwhelming emphasis in this population has been on the monitoring and preservation of left ventricular systolic function, we are now developing a greater appreciation for the plethora of cardiac sequelae beyond this basic model. To this end many institutions across the country have developed cardio-oncology programs, which are collaborative practices between oncologists and cardiologists in order to minimize a patient's cardiovascular risk while allowing them to receive the necessary treatment for their cancer...

Cardiovascular magnetic resonance imaging is a recently developed noninvasive, nonradiating, operator-independent technique that has been successfully used for the evaluation of congenital heart disease, valvular and pericardial diseases, iron overload, cardiomyopathies, great and coronary vessel diseases, cardiac inflammation, stress-rest myocardial perfusion, and fibrosis. Rheumatoid arthritis and other spondyloarthropathies, systemic lupus erythematosus, inflammatory myopathies, mixed connective tissue diseases (CTDs), systemic sclerosis, vasculitis, and sarcoidosis are among CTDs with serious cardiovascular involvement; this is due to multiple causative factors such as myopericarditis, micro/macrovascular disease, coronary artery disease, myocardial fibrosis, pulmonary hypertension, and finally heart failure...

OBJECTIVE: Extracellular matrix proteinases are implicated in the pathogenesis of calcific aortic valve disease. The ADAMTS5 (a disintegrin and metalloproteinase with thrombospondin motifs 5) enzyme is secreted, matrix-associated metalloendopeptidase, capable of degrading extracellular matrix proteins, particularly matrilin 2. We sought to determine the role of the ADAMTS5/matrilin 2 axis in mediating the phenotype transition of valvular interstitial cells (VICs) associated with calcific aortic valve disease...

Granulomatosis with polyangiitis (GPA) is a rare vasculitis that can have multisystem involvement, though cardiac involvement is very rare. The case is described of a 53-year-old woman who presented with acute aortic and mitral valve regurgitation requiring surgical intervention. Pathology from the excised aortic valve showed geographic necrosis concerning for GPA. Subsequent rheumatologic testing was positive for anti-serine proteinase 3 (PR3) antibody, consistent with GPA. A year after the valve surgery the patient was found to have a vegetation of the mitral valve and elevated PR3 antibody levels, and was successfully treated with an intensification of immunosuppression...

Transcatheter heart valve replacement is an emerging technology in the treatment of valvular disease. During recent years, the opportunity to replace a heart valve via percutaneous access or via a miniinvasive access without the use of cardiopulmonary bypass has revolutionized the approach to this pathology. The different designs of transcatheter valves have also altered the spectrum of possible complications, with the unexpected occurrence of leaflet hypomobility after valve deployment. Here, the pathophysiological pattern of this complication is categorized, and an analysis provided of recently reported clinical evidences...

BACKGROUND: Oral anticoagulation (OAC) therapy is associated with increased periprocedural risks after cardiac implantable electronic device (CIED) implantation. Patterns of anticoagulation management involving non-vitamin K antagonist oral anticoagulants (NOACs) have not been characterized. HYPOTHESIS: Anticoagulation strategies and outcomes differ by anticoagulant type in patients undergoing CIED implantation. METHODS: Using the nationwide Outcomes Registry for Better Informed Treatment of Atrial Fibrillation, we assessed how atrial fibrillation (AF) patients undergoing CIED implantation were cared for and their subsequent outcomes...

Aortic stenosis (AS) is the most frequently observed valvular heart disease. During the symptomatic stage, the rate of death increases dramatically, so that a precise diagnostic approach is taken to guide therapeutic options. Of patients with severe AS, 30% to 50% present with low-flow/low-gradient AS (LF/LGAS) status. This review focuses on LF/LGAS and the best diagnostic and therapeutic management in either classic LF/LGAS with reduced left ventricular ejection fraction (LVEF) or paradoxical LF/LGAS with preserved LVEF...

Background Young patients with congenital heart disease reaching adulthood face mandatory transition to adult cardiology. Their new cardiologist needs to assess the chances of major future events such as surgery. Using a large national registry, we assessed if patient characteristics at the age of 18 years could predict the chance of congenital heart surgery in adulthood. Design and methods Of 10,300 patients from the CONCOR national registry, we used general patient characteristics at age 18 years, underlying congenital heart defect, history of complications, and interventions in childhood as potential predictors of congenital heart surgery occurring from age 18 years up to age 40 and 60 years...

BACKGROUND: Accurate quantification of mitral valve (MV) morphology and dynamic behavior over the cardiac cycle is crucial to understand the mechanisms of degenerative MV dysfunction and to guide the surgical intervention. Cardiac magnetic resonance (CMR) imaging has progressively been adopted to evaluate MV pathophysiology, although a dedicated framework is required to perform a quantitative assessment of the functional MV anatomy. METHODS: We investigated MV dynamic behavior in subjects with normal MV anatomy (n=10) and patients referred to surgery due to degenerative MV prolapse, classified as fibro-elastic deficiency (FED, n=9) and Barlow's disease (BD, n=10)...

BACKGROUND: The endothelium is a key variable in the pathogenesis of atherosclerosis and its complications, particularly coronary artery disease (CAD). Current evidence suggests that the endothelial status can be regarded as an integrated index of individual atherogenic and anti-atherogenic properties, and that the interaction between circulating factors and the arterial wall might be critical for atherogenesis. In organism-level investigations, a functional view is provided by metabolomics, the study of the metabolic profile of small molecules...

OBJECTIVES: Double-outlet right ventricle is a form of ventriculoarterial connection. The definition formulated by the International Society for Nomenclature of Paediatric and Congenital Heart Disease is based on hearts with both arterial trunks supported in their greater part by a morphologically right ventricle. Bilateral infundibula and ventricular septal defects are highly debated criteria. This study examines the anatomic controversies surrounding double-outlet right ventricle. We show that hearts with double-outlet right ventricle can have atrioventricular-to-arterial valvular continuity...

Heart failure (HF) is a common end point for numerous cardiovascular conditions, including coronary artery disease, valvular disease, and hypertension. HF predominantly affects older individuals (aged ≥70 years), particularly those living in developed countries. The pathophysiological sequelae of HF progression have a substantial negative effect on physical function. Diminished physical function in older patients with HF, which is the result of combined disease-related and age-related effects, has important implications on health...

Non-alcoholic fatty liver disease (NAFLD) has become a public health burden all over the world. A significant percentage of the patients with NAFLD have a co-existing metabolic syndrome that is a risk factor for cardiovascular disease. Clinical as well as epidemiological research shows that NAFLD is not simply related to liver-related morbidity and mortality but is also associated with an elevated risk of coronary heart disease (CHD), irregularities of cardiac function as well as cardiac structure, valvular heart disease, and arrhythmias...

Mitral regurgitation is a common valvular heart disease and its prevalence is expected to increase with population ageing. In the recent years we have witnessed the evolution of several transcatheter devices to correct mitral regurgitation in patients at high-risk for surgery. Most of the evidence of the safety and efficacy of this new therapy comes from MitraClip studies. However, new alternatives have emerged with promising results. The aim of this position paper is to review the current evidence regarding patient selection, expected results and timing for transcatheter mitral valve interventions from the perspective of three European interventional societies...
