Filter by:Patients undergoing transcatheter valvular interventions will be prospectively included into the present registry. Baseline, procedural and follow-up data will be collected and analyzed to adress various issues in the field of percutaneous valvular interventions.
It is unclear to what extent systemic fluid overload has an impact on T1-mapping results by cardiovascular mangetic resonance imaging. In this study, patients will undergo body composition monitoring assessing systemic fluid overload and T1-mapping using MOLLI by cardiovacular magnetic resonance imaging in order to investigate a possible association with each other.
By bioelectrical impedance spectroscopy (BIS) association of fluid status in patients with valvular heart disease and cardiovascular outcome will be assessed.
Current European Society of Cardiology Guidelines recommend concomitant atrial fibrillation (AF) ablation for all symptomatic patients undergoing other cardiac surgeries, but the safety and potential benefits of concomitant atrial fibrillation (AF) ablation at the time of double valve replacement remains unexamined. A retrospective review of patients with AF who underwent double valve replacement with or without concomitant surgical ablation in our institute starting from April 2006.
We design a prospective, observational cohort study to provide contemporary information on the prevalence, characteristics, risk stratification，cost-effective ,treatments and prognosis of Chinese hospitalised adult patients with valvular heart disease.
The purpose of this study is to determine whether, in patients undergoing elective valvular heart surgery, revascularization of concomitant coronary artery disease (CAD) guided by FFR (Fractional flow reserve) would be superior to standard angiography-guided-revascularization approach on major efficacy and safety outcomes
The purpose of this study is to determine desflurane's dose-dependent effect on left ventricular (LV) function in cardiac surgery. The change of tissue Doppler imaging (TDI) of lateral mitral valve annular velocity at three different desflurane concentrations would be analyzed by using intraoperative transesophageal echocardiography (TEE) in cardiac surgery patients
Strategies for myocardial protection during open heart surgeries are desired. Several experimental studies have shown beneficial effects of remote ischemic preconditioning (RIPC). The underlying mechanisms are not totally understood. This study intends to evaluate molecular mechanisms involved with RIPC on myocardium of patients underwent open heart surgeries.
Our main hypothesis on the present study is that new parameters such as risk-taking behavior, patients motivation, health related quality of life, new biomarkers and more precise echocardiography measures in addition to traditional parameters will improve pre-operative risk assessment in patients with AS and better guide patients and doctors in decision whether to operate or not.
