Filter by:Coronary artery blockages can reduce blood flow to the heart muscle. Fractional flow reserve (iFR or FFR) assessment is an invasive tool used to determine how much blood flow is reduced. The investigators will perform iFR/FFR on all intermediate coronary stenoses using standard practice, immediately before (at the time of) transcatheter aortic valve replacement (TAVR) and after successful TAVR. The investigators will compare pre- and post-TAVR iFR/FFR values, and assess short-term outcomes. The investigators hypothesize that iFR/FFR values will be consistently and significantly higher pre-TAVR in comparison with post-TAVR for the same lesions.
Background: Transcatheter aortic valve replacement (TAVR) is a non-surgical alternative to standard surgical aortic valve replacement. Not all patients are eligible for TAVR using standard access through the artery in the groin, because the artery is too small or too diseased. In this study, TAVR is performed using a new technique called transcaval access. The catheter is placed in the artery deep in the body by crossing through the wall of a deep vein. The connection between that vein and the aorta is closed with a new metallic device they are testing. This is called a transcaval closure device (TCD). Objective: To test the safety and early feasibility of closure of transcaval aortic access sites using the TCD after TAVR. Eligibility: Adults ages 21 and older undergoing TAVR for whom the procedure cannot be performed safely by the standard artery approach Design: Participants will be assessed by heart experts including cardiologists and surgeons. Participants will have TAVR by the transcaval approach. A small catheter will be passed between the largest vein in the body and the nearby largest artery (aorta), inside the abdomen. Through this catheter, the TAVR will be implanted in the usual way. After, doctors will implant the TCD by catheter to close the hole made in the aorta. Participants will be X-rayed. A dye will be injected to view the TCD device. Participants will get standard TAVR care afterwards. They will have physical exams, blood tests, and scans. Participants will have a follow-up scan within 1 month and after 12 months. Participants will have follow-up visits and phone calls 6 and 12 months after the procedure.
Aortic valve stenosis (AS) shows high and increasing prevalence in Western civilizations and leads to high morbidity and mortality. 15 years ago Alain Cribier performed the first catheter-based transfemoral aortic valve replacement at the University of Rouon. This historical step initiated a dramatic shift in the treatment of AS with more than 50% of patients being treated interventionally instead of the surgical approach, today. Comorbidities are major determinants of cardiovascular events and clinical outcome in aortic valve stenosis but little is known about psychiatric comorbidities or frailty in these patients. Data from our group suggest an inflammatory trigger for depression and potentially other psychiatric diseases and aortic valve stenosis as well as aortic valve replacement are associated with considerable changes in the inflammatory state of the patients. However, no study has prospectively examined the interaction of these inflammatory markers and mood disorders, yet. In addition, frailty is a key aspect of many of TAVR patients clinically, however, scientifically there is only emerging data with half of all PubMed-indexed publications being less than 18 months old and clinical use of various scores still under discussion. The " Effect of interventional aortic valve replacement on emotional status, quality of life, frailty and inflammation"-study is designed to fill these gaps in evidence. It will be a prospective epidemiological cohort study to recruit 102 patients with symptomatic severe aortic valve stenosis within 18 months. All of these patients will undergo standardized cardiologic, psychiatric and frailty assessment as well as a sophisticated laboratory analysis focussing on the inflammatory state. The study aims to integrate these interdisciplinary findings to optimize patient treatment.
Safety and Efficacy of SYM-SV/DS-002 in Patients with Severe Aortic Stenosis
The objective of the REPRISE EDGE study is to confirm the acute performance and safety of the LOTUS Edge™ Valve System when used with the Lotus™ or iSleeve™ Introducer Set for transcatheter aortic valve implantation (TAVI) in symptomatic patients with severe calcific aortic stenosis who are considered high risk for surgical valve replacement.
The objective of this study is to evaluate feasibility, safety and effectiveness of the first generation transfemoral JenaValve Pericardial TAVR System (formerly named JenaValve TAVI Plus System- Transfemoral) in an elderly patient population with severe aortic stenosis who are at high risk for surgical aortic valve replacement.
The purpose of this study is to evaluate the safety and performance of the HLT System in patients with severe aortic stenosis who present at High Risk for aortic valve replacement surgery.
The aim of this pilot study is to establish whether a Supervised TAVR Exercise Program (STEP) can safely improve the frailty status in patients with symptomatic severe aortic valve stenosis prior to undergoing transcatheter aortic valve replacement (TAVR).
The Medtronic Transcatheter Aortic Valve Implant System (CoreValve System Family) has been demonstrated to be safe and effective for high through extreme risk patients with symptomatic severe native aortic stenosis or a stenosed, insufficient, or combined surgical bioprosthetic valve failure. Per DCGI systematic post marketing surveillance requirement, the purpose of this PMS plan is to provide local post marketing surveillance data regarding the safety of Medtronic CoreValve System Family
Multi-center, International, Prospective, Non comparative, Non randomized, Open label. 5,000 patients to be enrolled approximately worldwide. The objective of this registry is to collect safety and clinical performance post market data related to the procedure and follow-up of the Sorin Group aortic valve devices in accordance with the Instructions for Use (IFU). This observational global registry is intended to collect data without requiring any deviation from the standard of care and IFU in each participating center. The participating centers shall include those patients that have provided their informed consent to participate in this registry in accordance with the local applicable regulations.
