Filter by:This study aims to investigate the prevalence and characteristics of multiple and mixed valvular heart disease (MMVD), which includes combinations of stenotic or regurgitant lesions on cardiac valves. The research will be conducted as a multicenter observational study, involving several centers worldwide, and will have a one-year follow-up period (with a possible extension to 5 years). The primary aim is to determine the proportion of MMVD among patients evaluated for valvular heart disease. Secondary aims include the evaluation of the epidemiologic distribution of clinical, biological, and cardiovascular imaging characteristics at baseline, management strategies, and their impact on prognosis. The study will also evaluate clinical outcomes such as mortality, hospitalization for heart failure, and changes in echocardiographic parameters. This research aims to provide valuable insights into the diagnosis, management, and prognosis of MMVD, addressing an important knowledge gap in this area.
Swan Ganz catheter-Edwards Lifesciences obtains values of cardiac output/index and systemic vascular resistance/index using the mean artery pressure of either radial or femoral artery. During weaning from extracorporeal circulation, arterial waveform-derived cardiac output measurements from radial cannulation site is not reliable as compared with measurements obtained from femoral cannulation site.
The objective of the study is to evaluate the safety information on the Perceval S sutureless prosthetic heart valve after the implantation for aortic valve disease. The study is designed as a post-market, observational, non-interventional retrospective and prospective registry.
This study is an observational study to evaluate the long-term safety and effectiveness of the valve system.
The goal of the 3D-CARDIOPATH study is to investigate the potential added value of emerging 3D imaging modalities by imaging ex vivo cardiac specimens (diseased coronary arteries, calcific aortic valves, and thrombotic materials) in 3D. Specifically, 20 cadaveric coronary artery segments with advanced atherosclerosis will be received from 10 patients with SCD. These segments will first be scanned with intravascular imaging modalities, namely optical coherence tomography (OCT) and intravascular ultrasound (IVUS), and then with micro-computed tomography (micro-CT) and light sheet fluorescence microscopy (LSFM). Additionally, 30 thrombotic specimens aspirated from patients with ST-elevated myocardial infarction, will also be scanned using micro-CT. Finally, 30 surgically removed aortic valves will undergo scanning with micro-CT and LSFM. Traditional histopathological assessment will also be performed on the scanned specimens. Patient laboratory profiles, past medical histories, demographic characteristics, and therapeutic management will be recorded, where applicable.
The goal of this clinical trial is to evaluate the safety, effectiveness, and performance of Venus-Neo Surgical Aortic Valve in subjects who are clinically indicated for aortic valve replacement.
This is a prospective, randomized, comparative, clinical trial conducted by Wuhan Union Hospital that aims to evaluate the efficacy and safety of pioglitazone compared to placebo in patients with calcific aortic valve disease with mild aortic valve stenosis.
This is a prospective, randomized, comparative, clinical trial conducted by Wuhan Union Hospital that aims to evaluate the efficacy and safety of folic acid compared to placebo in patients with calcific aortic valve disease with mild aortic valve stenosis.
DIAMOND study is a national, multicentre, randomized, parallel-group, open label study in patients (aged ≥18 years) with mechanical aortic valve at least 7 days after cardiac surgery. Experimental group: Patients treated with apixaban 5 mg twice daily (BID) Active Comparator group: Patients treated with warfarin with an objective of INR target of 2.5 (range: 2.0-3.0) The Primary objective is To demonstrate that antithrombotic treatment with apixaban is non-inferior to warfarin (INR target range 2.0 - 3.0) in patients with mechanical heart valve implanted in the aortic position for at least 7 days for the primary net clinical benefit endpoint of ischemic outcomes (death, myocardial infarction, stroke, systemic embolism and valve thrombosis) and bleeding (ISTH major and non-major clinically relevant bleeding).
To collect information about the management of symptomatic severe Aortic Stenosis (AS) and Aortic Regurgitation (AR) using transcatheter aortic valve replacement (TAVI).
