Colchicine and Inflammation in Aortic Stenosis

Aortic Valve DiseaseAortic Valve Stenosis4 more

Aortic stenosis (AS) is the most common valvular heart disease in the developed world. Once symptomatic, untreated patients have a poor prognosis with five-year survival rate of 25%. Once at an advanced stage, AS will lead to the development of left ventricle hypertrophy, and eventually heart failure and death. At-present, there is no effective medical therapy for aortic stenosis. Current management of patients with AS consists of 'watchful waiting'. Valve replacement is needed when these patients (often acutely) become symptomatic. Recent studies have shown that inflammatory processes with similarities to atherosclerosis play an important role in AS. Therefore, we hypothesize that treatment with anti-inflammatory therapy, in the form of colchicine, could reduce the progression of AS. If positive, this trial will be the first to provide a potential therapeutic option for millions of people world-wide with AS.

A Study to Evaluate the Efficacy and Safety of DA-1229 (Evogliptin) in Patient's Calcific Aortic...

Calcific Aortic Valve Disease

This is an adaptive Phase 2/3 multicenter, double-blind, placebo-controlled, randomized, parallel, 3 arm study to evaluate the efficacy and safety of DA-1229 compared to placebo in patients with calcific aortic valve disease with mild to moderate aortic stenosis. There are 3 arms in this study to which patients will be randomized in a ratio of 1:1:1 to receive the DA-1229 or placebo orally once daily for a period of 104 weeks . the 3 arms are: placebo, DA-1229 5mg GroupDA-1229 10 mg Group. The study will have three phases: Screening Period (up to 4 weeks), Treatment Period (104 weeks), and Follow-Up Period (2-4 weeks). Total Study Duration is112 Weeks.

Quantitative Flow Ratio (QFR) Guided Revascularization Strategy for Patients Undergoing Primary...

Primary Valvular Heart Disease With Comorbid Coronary Artery DiseasePlanned to Undergo Elective On-pump Valve Surgery Due to Primary Mitral and/or Aortic Valvular Heart Disease

This is a multicenter, prospective, randomized, blinded, controlled clinical study in patients with planned primary valvular surgery and comorbid coronary artery lesions with diameter stenosis of ≥ 50%, to compare the effectiveness of an Quantitative Flow Ratio (QFR)-guided revascularization strategy and a coronary angiography (CAG)-guided revascularization strategy in preventing the incidence of composite outcome (MACE-5, including all-cause death, myocardial infarction, stroke, unplanned coronary revascularization, and new renal failure requiring dialysis) within 30 days after surgery. The study hypothesis is that the QFR-guided strategy can reduce the incidence of the MACE-5 within 30 days after surgery, as compared with the CAG-guided strategy.

Tocilizumab, Dexamethasone, Olanzapine, Hemodynamics, and Ventilation in Cardiac Surgery

Coronary Artery DiseaseAortic Valve Disease

Open heart surgery, including coronary artery bypass grafting (CABG) and/or aortic valve replacement (AVR) is associated with a significant risk of mortality. This study is a randomized clinical trial with the purpose of investigating five different interventions on the primary endpoint 'days alive and outside of hospital within 90 days'. The interventions are: Tocilizumab vs. placebo administered after induction of anesthesia. Dexamethasone vs. placebo administered after induction of anesthesia. Olanzapine vs. placebo administered prior to anesthesia. A blood-flow targeted vs. a blod-pressure targeted hemodynamic strategy while the patient is on cardio-pulmonary bypass (CPB) Low-tidal volume ventilation vs. no ventilation of the lungs while the patient is on CPB

Effect of PCSK9 InhibitorS On Calcific Aortic Valve DiseasE

Aortic Stenosis

Calcific Aortic Stenosis (CAS) can cause severe adverse cardiac events, but there is currently no effective drug that can prevent or delay the progression of the disease, aortic valve replacement is still the only therapy. The epidemiology of CAS shows that it is related with level of Lp(a)、LDL-C and PCSK9. Several observational studies indicate that the use of statins to decrease the level of LDL-C is associated with the reduced incidence of CAS, but no Randomized Control Trials(RCTs) show that statins have any benefit on the progression or clinical outcome of CAS,so the investigators speculated that this may be related to the limited reduction of LDL-C by statins therapy. The proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor has emerged as a new lipid-lowing drug. On the basis of statin treatment, it can further reduces LDL-C and Lp(a) concentrations by 50% to 60% and 20% to 30%,respectively. Some studies report that elevated plasma PCSK9 levels are related to CAS and PCSK9 R46L loss-of-function mutation are associated with lower rates of CAS, and other observational studies found that PCSK9 inhibitors can reduce the incidence of CAS. The research, on the basis of statins therapy, intends to study the effect of PCSK9 inhibitors on delaying or preventing patients with CAS. A total of 160 patients are planned to be selected for the presence of CAS that are confirmed by echocardiography but currently do not need valve replacement, and with the diagnosis of hypercholesterolemia. All of the patients were followed at 4 weeks、24 weeks 、48 weeks and 96 weeks for a minimum of 2 years. The primary endpoint is the average annual change in aortic-jet velocity. Secondary endpoints include average annual change of aortic valve calcification score that measured by Computed Tomography and major adverse cardiovascular events (cardiovascular death, non-fatal stroke or non-fatal myocardial infarction). The outcomes of the study will provide new ideas for the treatment of patients with CAS, and will also provide an important theoretical basis for the expansion of the clinical indications of PCSK9 inhibitors and the exploration their extra-lipid-lowering effects.

TriRec - Trileaflet Reconstruction of the Aortic Valve With Autologous Pericardium

Alternative Surgical Treatment for Aortic Valve Disease

Reconstruction of the aortic valve using the tri-leaflet repair technique is non-inferior with regard to effective orifice area (EOA) to surgical aortic valve replacement (SAVR) with a biological prosthesis (St. Jude Trifecta GT) as gold- standard.
