Filter by:The aim of this study is to analyse the short-term results of the first patients undergoing the OZAKI procedure (Aortic valve reconstruction using autologous pericardial tissue) at the department of cardiac surgery/ University Hospital Basel/ Switzerland.
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.
This study evaluated effectiveness and safety of aortic valve replacement in real-world clinical practice.
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.
The main purpose of this study is to define the complex genetic and pathogenic basis of thoracic aortic aneurysm (TAA) and other forms of aortopathy and/or aortic valve disease by identifying novel disease-causing genes and by identifying important genetic modifiers for aortic and aortic valve disease severity.
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.
Aortic stenosis is a frequent valvulopathy in Europe and North America. It occurs mainly over 65 years (2-7% of the population over 65 years). Treatment of symptomatic stenosis is an indication of aortic valve replacement. For patients with high surgical risk (EuroSCORE II> 6), TAVI (Transcatheter Aortic Valve Implantation) is recommended. This type of procedure concerns elderly patients (75-80 years on average in the literature) therefore the anesthesia technique must be optimal. The postoperative complications are, on the one hand, well-described surgical complications (Cardiogenic shock, bleeding, rhythm disorders, renal insufficiency) and, on the other hand, those related to anesthesia which are less well characterized. There is no consensus on best anesthesia technique for TAVI procedure managment. Between teams practices are different. It may consist of general anesthesia (GA) or local anesthesia with sedation (LASed). Elderly anesthesia has specific complications, including acute cerebral disturbances (delirium) usually occurring within 24 to 48 hours postoperatively and up to 7 days. It is recommended to screen delirium for patients admitted in intensive care using the CAM-ICU scale. The aim of the study is to observe the impact of the anesthesia technique (GA versus LASed) on delirium in post-operative aortic valve replacement with TAVI procedure
Aortic Stenosis is a common but fatal disease when it becomes symptomatic, specially if not treated. Until now surgery remains the only reliable and effective treatment. In this study, the investigators will examine the effect of high dose of Menaquinone-7 (MK-7) supplementation (1000 mcg)/day on the progression of the aortic valve disease. The investigators hypothesize that MK-7 supplementation may slow or even reverse the progression of the disease process.
The aim of our study was to investigate, whether enhancement of left atrial cryoablation by ablation of the autonomic nervous system of left atrium leads to influencing the outcomes of surgical treatment of atrial fibrillation in patients with structural heart disease undergoing open-heart surgery.
