Active clinical trials for "Aortic Valve Disease"

Study Objectives/Specific Aims Overall Goal: To study the outcomes of patients undergoing TAVI, their subsequent results and complications. Objective 1: Identify risk factors that are predictive of the need for TAVI and CABG Objective3:Assess early 3 months outcomes and postoperative results Outcome Measure: 1. All-cause mortality within 3 months. Secondary Outcome Measures: Stroke Myocardial infarction Bleeding Hospital stay Acute kidney injury Number of patients with conduction disturbance and pacemaker implantation Gradient on implanted valve Degree of transvalvular leakage 6 weeks follow-up 3 months Echo

With the aging of Chinese population, degenerative valvular disease is becoming more and more frequent, which has brought a heavy burden to our society. Taking aortic stenosis (AS) as an example, the incidence of AS in population over the age of 65 are about 2%, and in population above the age of 85 can be amounted to 4-8%, in the Western country. Since the invention of transcatheter aortic valve replacement (TAVR),aortic valve disease (AVD),including AS and aortic regurgitation (AR), has attracted more and more attention. To date, there are few data about the prevalence of AVD in China. The characteristics and prognosis of AVD in China are still unknown. Therefore, the investigators design a prospective, observational cohort study to investigate characteristics, treatments and prognosis of AVD in Chinese elderly population. The results of the study will provide a basis for the future national health policy for prevention and treatment of AVD in the elderly.

Prospective Cohort Study aims at elaborating the outcomes of the Tricuspid Reconstruction of Aortic valve leaflets using autologous pericardium (Ozaki procedure) in the adult and paediatric patients. A very promising technique with the potential benefits of dodging oral anticoagulation, foreign material, and suitable for patients with small aortic annuli and in infectious endocarditis. Performing hemodynamic evaluation, assess the clinical implementation and report preliminary results at follow up .

With the current knowledge of aortic valve replacement modalities, no specific recommendations can be given and the decision for a particular prosthesis or procedure is rather arbitrarily. The investigators hypothesize that the autograft procedure according to Ross is superior in terms of hemodynamic (especially regression of left ventricular hypertrophy) and major adverse valve related events even in a long-term course

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

Overall Goal: To study the outcomes of patients undergoing aortic valve surgeries, different approaches such as standard aortic valve replacement, aortic valve repair, novel techniques as Ozaki's procedure and their subsequent results and complications. Objective 1: Identify predictors of complications following different types of aortic valve surgery accordingly. Objective 2: Determine the value of each type in terms of advantages and disadvantages. Objective3: Assess outcomes such as postoperative life expectancy, hospital stay, prognosis and quality of life.

The CAvEAT study is a not for profit, international, multicenter study aimed to assess the feasibility of selective coronary angiography (CA) after Transcatheter Aortic Valve Implantation (TAVI), to investigate predictors of successful selective cannulation (anatomical, technical, etc.) and to investigate if there is a significant difference among different type of transcatheter valves in selective coronary cannulation.
