Filter by:The arrhythmogenic right ventricular cardiomyopathy, also known as arrhythmogenic right ventricular dysplasia (ARVC/D) is a rare myocardial disease with a prevalence estimated to range from 1 case on 5000 persons in the general population. It have a dominant genetic transmission characterized by alterations of desmosomial proteins and predominantly affects the right ventricle. The morphological alteration of the myocardium characterized by fibro-fatty substitution predisposes to arrhythmic events that can be fatal and cause death especially in young people and athletes. International guidelines provide a classification that includes clinical and histological criteria for diagnosis based on fibrous tissue substitution, percentage and right ventricle localization. Indeed, it is mainly affected the right ventricle but in some cases also the left ventricle result involved and the fatty tissue or fibro-fatty tissue with particular arrangement may affect the full-thickness wall are pathognomonic. Authors identified 10 cases of arrhythmogenic cardiomyopathy in forensic autopsy collocated in the 2003 to 2017, included 8 males and 2 females. Their age ranged from 16 to 45 years with an average age of 28.8±8.1 years. However, authors would like to demonstrate that with ARVC/D cannot be include only cases with increased fibrosis and exclusive localization to the right ventricle nor even cases with electrocardiographic alterations and other evident clinical criteria. Indeed, in the analyzed cases authors observed an amount of fibrosis often less than the percentage reported in the literature and an involvement not only of the right ventricle but also of the septum and associated sinister ventricular modifications. To this must be added that the cases of death did not have a sudden death of relatives in family history as described in guidelines and therefore this criterion is not reliable for the purpose of a classification.
We examined the feasibility and reliability of a combined echocardiographic and right heart catheterization (RHC) approach for right ventriculo/arterial (R-V/A) coupling assessment in HF patients with dilated cardiomyopathy (D-CMP).
The purpose of the study is to assess the role of mitral valve apparatus in the development of outflow tract obstruction in patients with hypertrophic cardiomyopathy and to identify the best surgical treatment modality to relieve outflow tract obstruction in such patients
Prospective, Non-randomized, Single-arm Study to assess the accuracy of intracardiac echocardiography (ICE) for characterization of arrhythmogenic substrate in patients with ischaemic cardiomyopathy undergoing ventricular tachycardia (VT) ablation
Phase 3 efficacy and safety study to evaluate acoramidis (AG10) HCl 800 mg administered orally twice a day compared to placebo in subjects with symptomatic Transthyretin Amyloid Cardiomyopathy (ATTR-CM).
Background: The intra-aortic balloon balloon pump (IABP) has been used as a method of percutaneous circulatory assistance high surgical risk patients undergoing coronary artery bypass graft surgery (CABG); Although its applicability has been questioned by clinical trials showing poor impact to reduce the mortality due to cardiogenic shock associated with postoperative acute myocardial infarction (AMI), the real benefit reducing mortality in the postoperative context (PO) has not been determined examined through a prospective study with an adequate design. Objective: To compare PO complications such as mortality, perioperative infarction and other complications in patients with high surgical risk undergoing CABG in comparison with controls.
The main purpose of this study is to determine the prevalence of ATTR Cardiomyopathy among patients admitted due to Left Ventricular Hypertrophy (LVH) >15mm of unknown etiology by using a 99mTc-tracer scintigraphy based protocol
The overall aim of this project is to establish potential benefits of a novel lifestyle (physical activity and dietary nitrate) and pharmacological (angiotensin receptor neprilysin inhibitor) interventions in patients with hypertrophic cardiomyopathy (HCM). HCM is the most common genetic cardiovascular disease with a broad spectrum of disease severity. Angiotensin receptor neprilysin inhibitor reduces death, hospitalisation, and may improve cardiac function and exercise tolerance in heart failure. Exercise training is associated with a significant increase in exercise tolerance, but appear to have limited effect on measures of cardiac morphology or function in patients with HCM. Dietary supplementation with inorganic nitrate (i.e. concentrated nitrate-rich beetroot juice) improves exercise capacity, vasodilatation and cardiac output reserves while reduces arterial wave reflections, which are linked to left ventricular diastolic dysfunction and remodelling. Using a five-centre, open label, three-arm, pilot design, the present study will evaluate the effect of lifestyle (physical activity and dietary supplementation with inorganic nitrate) and pharmacological (angiotensin receptor neprilysin inhibitor sacubitril / valsartan) interventions in patients with HCM. The Aim is to examine whether these interventions improve functional capacity, clinical phenotypic characteristics, and quality of life in patients with HCM.
The goal of this study is to evaluate left atrial structural and functional abnormalities in stroke of undetected mechanism and atherosclerotic stroke with cardiac MRI.
Left ventricular dysfunction is common in the critically ill. The aim of this study is to assess the incidence and prognosis of left ventricular dysfunction in critically ill patients.
