Filter by:The purpose of this study is to conduct the initial clinical investigation of the Foldax Polymer Aortic Valve to collect evidence on the device's safety and performance. The study is anticipated to confirm successful clinical safety and clinical effectiveness with significant improvements in clinical hemodynamic performance.
This is a prospective, open, single arm, multi-center clinical study in China. The primary objective of this study is to demonstrate the safety and effectiveness of the PERCEVAL S heart valve when used to replace a diseased native or malfunctioning prosthetic aortic valve in the indicated Chinese population for tissue heart valve replacement and suitable to the PERCEVAL S valve. The secondary objectives are to collect all relevant device and subject demographics, procedural and hospital discharge, short and long-term data, as described in the secondary endpoints section.
The objective of CAREBANK study is to establish definitive relationships with human cardiac samples and clinical phenotypes in patients undergoing cardiac procedures. Specifically, the investigators aim at comparing atrial phenotypes from atrial fibrillation patients and controls. The work consists of three broad categories: A) role of atrial cardiomyopathy in atrial fibrillation; B) genetic defects predisposing to atrial fibrillation; and C) the role of inflammation in atrial fibrillation.
To date, no formal, randomized, prospective, head-to-head comparisons of surgical aortic valve replacement (SAVR) versus transcatheter aortic valve replacement (TAVR) have been undertaken in the severe aortic stenosis (AS) population with small aortic annuli. Objectives of the present study are to compare the hemodynamic performance (incidence of severe PPM and ≥ moderate AR) and clinical outcomes (death, stroke, major or life threatening bleeding) between TAVR and SAVR in patients with severe AS and small aortic annuli.
In Italy, life expectancy at birth has reached 80 years in men and 85 in women; in about 50 years, life expectancy at the age of 80 has increased by an extraordinary 61% and 55%, respectively, due to more effective therapies and lower mortality of many diseases. Yet, chronic diseases are nowadays more important, and often coexist as comorbidity or multimorbidity, depending on whether an index condition has been considered. These conditions increase the risk of death and reduce functional autonomy in the elderly and, therefore, should be carefully considered within comprehensive geriatric assessment. The epidemiology of valvular disease shows a clear trend in age-dependent, as the number of events and their incidence increases with age, and about half are concentrates over 75 years. In addition, some observational studies in elderly patients have suggested an association between frailty and cardiovascular disease: fragility and cardiovascular disease share a common biological pathway, and cardiovascular diseases may accelerate the onset of frailty. The frailty syndrome was identified in 25% to 50% of patients with cardiovascular disease, according to the rating scale used and the population studied. Frail patients with cardiovascular disease, in particular those undergoing invasive procedures or suffering from coronary artery disease and aortic valve disease, have a much higher adverse events and complications, suggesting the need for a more accurate functional stratification and a more careful evaluation of the risk/benefit ratio of some invasive procedures. Among the numerous tests proposed in the literature for the functional evaluation and objective measures of physical capability in elderly patient, the Short Physical Performance Battery (SPPB) and the evaluation of hand grip strength (grip strength) are those characterized by an improved prognostic ability and an easy administration. The present study is performed to assess if SPPB and handgrip are helpful to better stratify the prognosis (all-causes death and hospital admission for all causes) in elderly patients admitted to hospital for cardiac causes.
Patients undergoing open heart surgery are at risk of suffering damage to the heart, brain and kidneys. This study is designed as a 2-by-2 randomized clinical trial with the purpose of investigating the organ protective effects of the glucagon-like-peptide-1 (GLP-1) agonist Exenatide versus placebo and restrictive versus liberal oxygenation during weaning from cardio-pulmonary bypass.
Bicuspid aortic valve (BAV) disease is the most frequent congenital cardiac malformation, occurring in 0.5-1.2% of the US population. In young adults, it is generally a benign abnormality; but in older adults it is associated with thoracic aortic aneurysm or dissection in 20-30% of those with BAV. BAV is strongly associated with early development of aortic valve calcification or incompetence in >50% of BAV patients, and accounts for ~40% of the >30,000 aortic valve replacements (AVR) performed in the US each year. Yet, we know little of the etiology, cellular events and modifiers of progression of BAV to calcific aortic valve disease and we still do not understand the genetic cause(s) of BAV despite evidence for its high heritability. The Specific Aims of this study are: 1. To identify the genetic causes of bicuspid aortic valve disease and its associated thoracic aortic disease. 2. To identify potential pathways to predict the clinical course of BAV disease and for treating human BAV disease. To achieve these aims, we have created the International Bicuspid Aortic Valve Consortium (BAVCon), a consortium of institutions with cohorts of BAV patients and the expertise to fulfill the performance of these aims.
For this study, blood and tissue samples will be collected in order to perform genetic testing to help researchers gather information about this disease and how and why it affects some patients more than others.
BAVgenetics is a partnership between Investigators at Boston University, Brigham and Women's Hospital, and Massachusetts General Hospital dedicated to discovering the genetic causes of bicuspid aortic valve disease and associated aortic disease.
A prospective single arm study evaluating feasibility and safety of a catheter-based transapical implantation of the Ventor Embracer™ aortic valve bioprosthesis in patients with severe aortic valve disease, specifically aortic stenosis, who are at elevated risk for standard surgical valve replacement.
