Active clinical trials for "Constriction, Pathologic"

TEAM-Br is a randomized, prospective, cost-utility study comparing transcatheter aortic valve implantation (TAVI) versus surgical aortic vale replacement in Brazil. The study is sponsored by the national Minister of Health, through PROADI-SUS (Programa de Apoio ao Desenvolvimento Institucional do SUS).

The purpose of this clinical study is to evaluate the effectiveness and safety of the transcatheter aortic valve system in the treatment of patients with severe aortic stenosis who are at high risk of surgery or who are not suitable for surgery.

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.

This is a prospective, controlled, single-arm clinical investigation for the treatment of subjects with severe symptomatic aortic valve stenosis using Valvosoft® Pulsed Cavitational Ultrasound Therapy (PCUT) - First-In-man

This is a phase IV, randomised, placebo-controlled, double-blind, parallel group study to determine the effect of Evolocumab treatment on carotid plaque morphology and composition in asymptomatic patients with >50% carotid artery stenosis.

The purpose of the study is to investigate the safety and efficacy of transcatheter aortic valve implantation (TAVI) in patients with severe, symptomatic Aortic Stenosis (AS) at intermediate surgical risk by randomizing patients to either Surgical Aortic Valve Replacement (SAVR) or TAVI with the Medtronic CoreValve® System. Single Arm: The purpose of this trial is to evaluate the safety and effectiveness of transcatheter aortic valve implementation (TAVI) in patients with severe symptomatic Aortic Stenosis (AS) at intermediate surgical risk with TAVI. This is a non-randomized phase of the pivotal clinical trial.

The LimiFlex™ Clinical Trial is a prospective, concurrently controlled, multi-center study to evaluate the safety and effectiveness of decompression and stabilization with the Empirical Spine LimiFlex™ Paraspinous Tension Band compared to decompression and transforaminal lumbar interbody fusion (TLIF) with concomitant posterolateral fusion (PLF) for the treatment of lumbar degenerative spondylolisthesis (Grade I per Meyerding classification) with spinal stenosis. Clinical trial sites will enroll solely LimiFlex subjects or solely TLIF/PLF subjects.

This study will evaluate the safety and effectiveness of the Edwards SAPIEN 3/SAPIEN 3 Ultra Transcatheter Heart Valve (THV) compared with clinical surveillance (CS) in asymptomatic patients with severe, calcific aortic stenosis.

ROBUST III is a prospective, multi-center, randomized controlled adaptive sample size clinical trial to establish the safety and effectiveness for the Optilume Stricture Drug Coated Balloon (DCB).

DIGEST I Pilot study is a feasibility study for evaluating the safety and efficacy of DCBs.
