Filter by:The study collects real-world data of patients who were treated with the Acurate Neo TAVI System and evaluates early and midterm clinical outcomes.
This is an independent, investigator-initiated, prospective multicenter observational study with restricted grant provided by Edwards Lifesciences that aims to describe baseline (preoperative) physical function and to assess and compare 6-month postoperative changes in the physical function of patients undergoing aortic stenosis (AS) treatment with either transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) implanted with Edwards valve type ("SAPIEN 3" and "SAPIEN XT" for TAVR; "INSPIRIS RESILIA", "EDWARDS INTUITY" and "Carpentier-Edwards PERIMOUNT Magna-Ease" for SAVR). Secondary objectives of this study are: to evaluate the validity of wearable devices in assessing physical function in such patients and subjects' compliance in wearing the device also after a very long follow-up time up to 12 months; to assess and compare 6-month postoperative changes in Health-Related Quality of Life (HRQoL), sleep quality, cognitive function of patients undergoing AS treatment with either TAVR or SAVR. Smart watch activity tracker "Vívoactive® HR" devices by "Garmin©" will be used in the study. Devices will be distributed to the patients at time of baseline assessment, along with a Bluetooth-paired smartphone provided with a prepaid data-only SIM-card and study-customised interface. Patients will be asked to wear the device 24 hours a day, 7 days a week, from the baseline assessment to the last follow-up, 12 months after baseline.
The objective of this study is to evaluate the procedural and clinical outcomes of patients with bicuspid aortic valve stenosis undergoing transcatheter aortic valve replacement.
To prove the non-inferiority of TAVR-CMR compared to TAVR-CT to guide TAVR according to clinical efficacy, defined as implantation success based on the VARC-2 criteria.
To investigate whether the collagen-based MANTA vascular closure device (VCD) is superior to suture-based VCDs in preventing vascular access site complications in patients undergoing transfemoral transcatheter aortic valve replacement.
After surgery, patients who undergo transcatheter aortic valve implantation (TAVI) are at risk of developing cardiac arrhythmias such as heart blocks and atrial fibrillation. Current practice is to monitor TAVI patients in hospital for 2-8 days post procedure using scarce and expensive hospital telemetry beds. This study will use a new monitoring service called mobile Cardiac Arrhythmia Diagnostics Service (m-CARDS) to risk stratify patient pre-TAVI and provide an added layer of monitoring that would support earlier discharge of suitably identified patients 24-hours post TAVI. The study will assess whether this strategy will significantly reduce the pressure on hospital resources while improving patient outcomes and experience.
This study evaluates the clinical and hemodynamic outcome in patients after aortic valve replacement. Half of the patients will receive warfarin + aspirin and the other half will receive only aspirin. The investigators will focus mainly on early bioprosthesis degeneration.
To evaluate the safety and performance of the HLT System in patients with symptomatic heart disease due to severe aortic stenosis who are judged by the Heart Team to be at Intermediate or High Risk for aortic valve replacement surgery.
Aortic valve stenosis (AVS) is becoming more and more frequent with the aging, which has brought a heavy burden to the world. However, the prevalence and prognosis of valvular heart disease are not so clear, especially in the developing countries such as China etc. Because of the slow and progressive nature of AVS, symptoms might not be too severe to be diagnosed on time. Our retrospective survey (Int J Cardiol. 2016 Nov 25) indicated that severe aortic valve stenosis are very common in China. Hence, we design a prospective, observational cohort study to provide contemporary information on the prevalence, characteristics, risk stratification，cost-effective ,treatments and prognosis of Chinese elderly patients with aortic valve stenosis.
The purpose of this study is to demonstrate that transcatheter artificial aortic valve and transcatheter artificial heart values delivery system is associated with a reduction of all-cause mortality in severe aortic stenosis or insufficiency patients who are high risk or ineligible for aortic valve replacement.
