Since the 1990's cabergoline has been the treatment of choice in prolactinoma, as it permits rapid and effective hormonal and tumor control in most cases. Evidence of cardiac valvulopathy was demonstrated in Parkinson's disease patients treated with dopamine agonists. Retrospective studies in prolactinoma patients treated with cabergoline at lower doses did not show such an effect. However, few prospective data with long-term follow-up are available. The aim of this study was to assess the safety of cabergoline regarding cardiac valvular status during prospective follow-up in patients treated for prolactinoma or idiopathic hyperprolactinemia...

BACKGROUND: Cardiovascular magnetic resonance (CMR) is considered the gold standard of cardiac volumetric measurements. Flow in the aortic root is often measured at the sinotubular junction, even though placing the slice just above valve level may be more precise. It is unknown how much flow measurements vary at different levels in the aortic root and which level corresponds best to left ventricle volumetry. METHODS: All patients were older than 70 years presenting with at least one of the following diagnoses: diabetes, hypertension, prior stroke and/or heart failure...

: CONTEXT Uncertainty exists whether the long-term use of ergot-derived dopamine agonist (DA) drugs for the treatment of hyperprolactinemia may be associated with clinically significant valvular heart disease; and whether current regulatory authority guidelines for echocardiographic screening are clinically appropriate. OBJECTIVE: To provide follow-up echocardiographic data on a previously described cohort of patients treated with DA for lactotrope pituitary tumors; and to explore possible associations between structural and functional valve abnormalities with the cumulative dose of drug used...

BACKGROUND: Although atrial fibrillation (AF), a common arrhythmia, frequently presents in patients with underlying valvular disease, its hemodynamic contributions are not fully understood. The present work aimed to computationally study how physical conditions imposed by pathologic valvular anatomy act on AF hemodynamics. METHODS: We simulated AF with different severity grades of left-sided valvular diseases and compared the cardiovascular effects that they exert during AF, compared to lone AF...

In patients taking flecainide, exercise-induced arrhythmias are believed to be related to QRS widening at rest and during exercise. Our aim was to determine, retrospectively, predictive factors of flecainide-induced (a) QRS widening at rest and during exercise, and (b) proarrhythmia (PA) during exercise. Flecainide was administered to 119 patients for atrial and/or ventricular arrhythmias who performed a maximal treadmill test. A total of 63 patients had a normal heart (defined by the absence of structural heart disease and an ejection fraction ≥ 55% by echocardiography and/or cardiac catheterisation), 26 had coronaropathy, 18 valvulopathy and 3 had both, and 7 had dilated and 2 hypertrophic cardiomyopathy...

Cardiac involvement is rare in antineutrophil cytoplasmic autoantibody (ANCA)-associated systemic vasculitis but can involve aortic and mitral valves. We present an unusual case of a 65-year-old woman who presented 16 years after an aortic valve replacement with severe mitral regurgitation with ACNA-associated vasculitis. The extensive nature of the pathologic condition, which extended to the tricuspid valve, prevented the replacement of the mitral valve during a surgical procedure. This is a rare case in which florid valvulopathy was observed in association with vasculitis...

Cardiac involvement is fairly common in patients with systemic lupus erythematosus (SLE). It may involve all layers of the heart and coronary arteries as well as the heart valves. We report an extremely rare presentation of valvulitis and valvular dysfunction associated with systemic lupus erythematosus. This is the first case of lupus valvulitis which required three mechanical prosthetic valve replacements with disease recurrence leading to a fatal outcome. This is, in our point of view, the consequence of aggressive natural history of the disease and perhaps late diagnosis and treatment of underlying SLE which was unsuccessful...

Calcific diseases of the cardiovascular system, such as atherosclerotic calcification and calcific aortic valve disease, are widespread and clinically significant, causing substantial morbidity and mortality. Vascular cells, like bone cells, interact with their matrix substrate through molecular signals, and through biomechanical signals, such as traction forces transmitted from cytoskeleton to matrix. The interaction of contractile vascular cells with their matrix may be one of the most important factors controlling pathological mineralisation of the artery wall and cardiac valves...

UNLABELLED: SummaryWe present a very rare example of chronic right heart failure caused by torrent tricuspid regurgitation. Massive right heart dilatation and severe tricuspid regurgitation due to avulsion of the tricuspid valve apparatus occurred as a result of a blunt chest trauma following the explosion of a gas bottle 20 years before admission, when the patient was a young man in Vietnam. After this incident, the patient went through a phase of severe illness, which can retrospectively be identified as an acute right heart decompensation with malaise, ankle edema, and dyspnea...

BACKGROUND: Acromicric dysplasia (AD) and geleophysic dysplasia 2 (GD2) belong to the category of acromelic dysplasia syndromes, consisting of severe short stature, short hands and feet and skin thickening. Both can result from missense mutations in the transforming growth factor beta 5 domain of the fibrillin-1 gene (FBN1). METHODS: Two patients (P1 age 10, and P2 age 7) from unrelated families presented to their endocrinologist with severe short stature (approx...

Dravet syndrome (DS) is a rare and therapy-resistant epilepsy syndrome. A retrospective analysis of add-on fenfluramine treatment in 12 patients with DS was published in 2012 and provided evidence of a meaningful long-term response. Herein we present the results of a subsequent 5-year prospective observation of this original cohort. Ten patients with a mean current age of 24 years were followed prospectively from 2010 until 2014. The mean current dose of fenfluramine was 0.27 mg/kg/day, with a mean treatment duration of 16...

Mucopolysaccharidoses (MPS's) represent a subgroup of lysosomal storage diseases related to a deficiency of enzymes that catalyze glycosaminoglycans degradation. Mucopolysaccharidosis type I (MPS I) is a rare autosomal recessive disorder caused by a deficiency of α-l-iduronidase encoded by the IDUA gene. Partially degraded heparan sulfate and dermatan sulfate accumulate progressively and lead to multiorgan dysfunction and damage. The aim of this study is to describe the clinical, biochemical, and molecular characteristics of 13 Algerian patients from 11 distinct families...

Pulse pressure variation can predict fluid responsiveness in strict applicability conditions. The purpose of this study was to describe the clinical applicability of pulse pressure variation during episodes of patient hemodynamic instability in the intensive care unit. We conducted a five-day, seven-center prospective study that included patients presenting with an unstable hemodynamic event. The six predefined inclusion criteria for pulse pressure variation applicability were as follows: mechanical ventilation, tidal volume >7 mL/kg, sinus rhythm, no spontaneous breath, heart rate/respiratory rate ratio >3...

AIMS: Aortic valve stenosis (AS) is the most common valvulopathy and is characterized by inflammation, extracellular matrix (ECM) remodelling and calcification, causing a narrowing of the valve and the consequential obstruction of the cardiac outflow. Although intraleaflet haemorrhage is associated with AS progression, the mechanisms involved are not known. The aims of this study were to identify valvular iron in relation to pathological changes associated with AS and the effects on valvular interstitial cells (VIC) in terms of iron uptake and iron-induced responses...

Liver stiffness (LS) is associated with the presence of fibrosis; however, hepatic congestion due to elevated central venous pressure has also been shown to correlate with LS values. We report here the case of a 35-year-old woman with operated pulmonary stenosis and chronic pericarditis in whom longitudinal follow-up of LS was correlated with the changes in her hemodynamic conditions before and after surgical or percutaneous treatment of residual lesions. This case highlights the potential interest of LS as a reliable marker of hepatic congestion and elevated right ventricle (RV) filling pressures...
