Filter by:The aim of the study is to evaluate the short- and medium-term effectiveness of additional moderate dynamic resistance and balance training to the CR-program of old adults after valve surgery or intervention compared to usual care-CR.
Cardiac surgery is associated with post-operative pain which is one of the major problems and remains one of the most controversial issues. Inadequate pain control after cardiac surgery increases the incidence of development of many complications. Intravenous opioids are commonly used for postoperative analgesia either on demand "physician or nurse-controlled" or patient -controlled. Multimodal opioid sparing analgesia has become frequently used, These techniques can be achieved with Dexmedetomidine, low-dose ketamine and magnesium. The study hypotheses that control of perioperative quality of pain with opioid sparing medications may improve analgesia and patient outcome.
Prospective, multi-center study to assess safety and performance of the Edwards EVOQUE Tricuspid Valve Replacement System
The objective of this study is to evaluate the 5-year outcomes of participants with degenerative mitral valve disease treated with the NeoChord Artificial Chordae System, Model DS1000 in a post-market setting.
Purpose of this prospective, randomized, controlled, multi-center study is to evaluate the safety and efficacy of Transcatheter Aortic Valve Implantation (TAVI) as compared to surgical aortic valve replacement (SAVR) in female patients with severe symptomatic aortic stenosis. Patients will be randomized 1:1 to receive either TAVI or SAVR aortic valve replacement. For TAVI procedure, Edwards SAPIEN 3 THV system Model 9600 TFX (20, 23, 26 and 29 mm) or SAPIEN 3 Ultra THV system Model 9750 TFX (20, 23, 26) with the associated transfemoral delivery systems will be sued, for SAVR any commercially available surgical bioprosthetic valve. Patients will undergo the following visits: Screening, Procedure, Post Procedure, Discharge, 30 day, 6 months (telephone contact) and 1 year.
This study aims to identify the molecular genetic causes of the variability in development of calcific aortic valve disease in bicuspid and tricuspid aortic valves and their associated aortic dilation.
The purpose of the study is to compare the various 2D and 3D methods of valvular heart disease quantification (Doppler, PISA, VCA, volumetric method) and strain with cardiac magnetic resonance (CMR) measurements of left and right ventricular systolic function strain and myocardial fibrosis assessment.
- assess feasibility of detecting pulmonary complications postoperative using chest ultrasound compared to chest x-ray - measure time lag between using ultrasound and using chest x-ray to detect pulmonary complications postoperative
Patients with bicuspid aortic valve-related aortopathy are at increased risk of aortic dilatation, dissection and rupture. Currently, risk stratification is largely based on aortic diameter measurements, with those deemed high risk referred for aortic replacement surgery. This approach is imperfect, and potentially exposes many patients to unnecessary high-risk aortic surgery, or fails to identify those at risk of dissection or rupture with smaller diameters. In patients with abdominal aortic aneurysms, the investigators recently demonstrated that uptake of 18F-sodium fluoride predicts disease progression and clinical events independent of aneurysm diameter and standard clinical risk factors. Based on the investigators preliminary data, a study was proposed to look at 18F-sodium fluoride uptake in patients with bicuspid aortic valve-related aortopathy. The proposed study will shed light on the underlying pathological processes involved in aortic complications of this disease as well as potentially providing an important risk marker to predict disease progression and guide the need for major aortic surgery.
Sleep-disordered breathing has a prevalence of 30~80% in patients with heart diseases. Various studies have revealed a correlation between the incidence and various diseases such as heart failure, hypertension, diabetes, and cerebral infarction. Postoperative acute kidney injury after heart surgery is one of the major complications with incidence with 40~50%, however, there has been no preventive method or treatment yet. Recently, several studies have been published that have shown a correlation between sleep-disordered breathing and renal impairment. In general, sleep-disordered breathing can be regulated easily with continues positive expiratory pressure, which means that early diagnosis and treatment of sleep-disordered breathing might help to reduce the incidence of postoperative acute kidney injury and improve patients' prognosis. In this study, the investigators investigate the impact of sleep-disordered breathing (diagnosed by oxygen desaturation index ≥5) on the incidence of postoperative acute kidney injury in patients undergoing valvular heart surgery.
