Filter by:The investigators prognostic impact of coronary artery disease (CAD) and of percutaneous coronary intervention (PCI) in patients with indication of TAVI is controversial, particularly in elderly population where CAD and aortic stenosis (AS) are frequent and commonly coexisted. (1-2) The primary end point of this prospective study is to compare major cardiovascular event at one year of follow up in patients over 80 years with severe aortic stenosis who referred for TAVI with or without associated CAD. The investigators will also assess (secondary endpoint) the impact of PCI on symptoms, major events and quality of life using geriatric parameters. The study will be conducted in the University hospital of Montpellier between November 2020 and November 2022
Severe aortic stenosis (AS) is the commonest form of valvular abnormality in the developed world and transcatheter aortic valve implantation (TAVI) is now widely practiced as in many cases is the preferred treatment option over conventional aortic surgery. Several studies have shown that females have an apparent better outcome with TAVI than males. There are a number of possible reasons as to the apparent favourable benefit of TAVI in women including: having both lower rates of moderate / severe aortic regurgitation and peri-procedural mortality, lower rates of bleeding and renal failure, better patient prosthesis match and recovery of left ventricular function with more favourable left ventricular remodelling. We aim to explore the long term outcomes of TAVI between males and females to try and identify specific tailored treatment options. This data will be useful in providing important information regarding gender differences in patients who are treated with transcatheter aortic valve implantation. Data provided will include long term outcomes and predictors of outcome. The study team will then identify and implement strategies to improve outcomes in patients being treated with transcatheter aortic valve implantation.
This study is intended to investigate the effect of angiotensin receptor blockers (ARBs) on mild-to-moderate aortic stenosis.
The purpose of this study is to determine the prevalence of transthyretin cardiac amyloidosis (TTR-CA) among patients with moderate and severe aortic stenosis in Southeast Minnesota using 99mTc-PYP single-photon positive emission computed tomography with computed tomography (SPECT/CT).
This study will evaluate real-world outcomes for the SAPIEN 3 Ultra Transcatheter Heart Valve System in transcatheter aortic valve implantation centres that are implementing minimalist periprocedural practices and facilitating early discharge home.
The DISCORDANCE TAVR study will determine the discordance between echocardiography-derived and invasive transaortic gradients, as determined by a consistent and reproducible technique (Standardized Invasive Hemodynamics) post-TAVR.
To observe and evaluate the safety and efficacy of TaurusOne® transcatheter aortic valve system in patients with severe calcific aortic stenosis through a prospective, multicenter clinical trial using objective performance criteria.
Iron deficiency is common among patients undergoing TAVI. It is estimated at 54-79%. Previous non-randomized small trial have shown symptomatic benefit in treating iron deficiency in this group of patients. The investigators predict, that as IV iron will improve symptoms, quality of life and exercise tolerance in this group of patients.
The INERTIA trial is a multicenter double-blinded randomized trial of intravenous iron supplementation in patients with severe aortic stenosis and iron deficiency undergoing TAVI or SAVR. The primary endpoint is the time to HF hospital admission or cardiovascular death. Secondary endpoints will assess quality of life indicators and functional capacity at 6 months.
The TaurusOne® transcatheter aortic valve system with retrievable delivery catheter system is evaluated the safety and effectiveness for the delivery of artificial aortic valve in a prospective, multicenter, single-arm clinical trial.
