Active clinical trials for "Aortic Valve Stenosis"

The R-TAVI study is a randomized pilot study examining the use of the right radial artery versus the femoral artery for secondary vascular access during transcatheter aortic valve implantation (TAVI).

This study is a randomised comparison of apical stent valve treatment versus conventional valve surgery in patients with severe aortic valve stenosis.

This is a single-centre, prospective, observational cohort study focusing on of patients suffering severe aortic valve stenosis (AS) undergoing emergent transcatheter aortic valve implantation (TAVI). AS patients undergoing emergent TAVI always have complicated clinical situations. Therefore, the aims of the study are to collect the incidence and outcomes of emergent TAVI in patients with severe symptomatic AS, to assess the safety and effectiveness of emergency TAVI system for severe AS, and to describe a more practical evidence of emergency TAVI system in severe AS patients.

The aim of the study is to evaluate the clinical efficacy of 2 different vascular closure device (VCD) strategies during transfemoral transcatheter aortic valve implantation (TAVI). The study hypothesizes that the choice of one over the other VCD in patients undergoing transfemoral TAVI may demonstrate relevant differences in the rate of peri-procedural complications and effectiveness of vascular closure.

The objective of this study is to confirm the safety and effectiveness of the Lotus™ Valve System in the Japanese medical environment for transcatheter aortic valve replacement (TAVR) in symptomatic subjects with calcific, severe native aortic stenosis who are considered at high or extreme risk for surgical valve replacement.

First clinical experience on the ACURATE TF™ Transfemoral Aortic Bioprosthesis Implantation in Patients with Severe Aortic Stenosis to collect human data pertaining to the safety and performance of the device from three different cohorts

To assess the safety and feasibility of Transcatheter Aortic Valve Replacement (TAVR) with commercially available bioprostheses in patients with severe, symptomatic aortic stenosis (AS) who are low-risk (STS score ≤3%) for surgical aortic valve replacement (SAVR).

The purpose of this investigation is to collect data pertaining to the safety and performance of the ACURATE neo (TM) Aortic Bioprosthesis as implanted with the ACURATE neo (TM) TA Transapical Delivery System. This device is intended for treatment of subjects with severe aortic stenosis (AS) who have high risk for conventional aortic valve replacement (AVR) surgery. The ACURATE neo (TM) Aortic Bioprosthesis is intended for use via minimally-invasive transapical implantation in a well-defined population.

The purpose of this study is to evaluate safety of the study device and study device performance in patients presenting with severe aortic stenosis who are considered to be high risk for open surgical repair.

This study is being performed in patients who have undergone transcatheter aortic valve replacement (TAVR) for aortic stenosis. The goal is to obtain pilot and feasibility data on a novel post-procedure rehabilitation strategy, including a daily activity goal using a fitness tracking device (Fitbit Alta HR) and in-home resistance training exercises targeting muscles related to activities of daily living. We will evaluate the effect of these interventions on physical performance and several quality of life domains.
