Valvosoft First-In-Human Study in Severe Symptomatic Aortic Stenosis

Aortic Valve Stenosis

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-Human

SMall Annuli Randomized To Evolut™ or SAPIEN™ Trial

Symptomatic Aortic StenosisAortic Valve Stenosis1 more

The purpose of this trial is to generate clinical evidence on valve safety and performance of self-expanding (SE) versus balloon-expandable (BE) transcatheter aortic valve replacement (TAVR) in subjects with a small aortic annulus and symptomatic severe native aortic stenosis. Additionally, a stress echocardiography sub-study will be conducted as part of the SMART Trial at select sites. The purpose of the sub-study is to evaluate performance of SE versus BE TAVR in subjects with a small aortic annulus and symptomatic severe native aortic stenosis after undergoing exercise stress echocardiographic testing.

PrizValve® Transcatheter Aortic Valve Replacement Study

Aortic Valve Stenosis

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.

Revascularization in Patients Undergoing Transcatheter Aortic Valve Implantation

Coronary Artery DiseaseAortic Valve Stenosis2 more

The aim of this study is to evaluate the effect of routine FFR-guided complete revascularization with PCI compared to conservative management in patients with concomitant coronary artery disease who are undergoing TAVI.

Medtronic Evolut Transcatheter Aortic Valve Replacement in Low Risk Patients

Aortic Valve Stenosis

The study objective is to demonstrate that the safety and effectiveness of the Medtronic TAVR system as measured by rates of all-cause mortality or disabling stroke at two years is noninferior to SAVR in the treatment of severe aortic stenosis in subjects who have a low predicted risk of operative mortality for SAVR. The purpose of the expanded use addendum to the Medtronic TAVR in Low Risk Patients Trial protocol is to conclude the randomized phase of the trial and initiate the single-arm, non-randomized, continued access phase of the trial.

Severe Aortic 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.

Symptomatic Degenerative Aortic StenosisSevere Aortic Stenosis

The purpose of this clinical investigation is to characterize the procedural safety and device performance of transfemoral implantation of the Portico™ Transcatheter Aortic Heart Valve in patients with symptomatic degenerative aortic stenosis.

Degenerative Aortic Valve DiseaseAortic Stenosis1 more

To date, no formal, randomized, prospective, head-to-head comparisons of surgical aortic valve replacement (SAVR) versus transcatheter aortic valve replacement (TAVR) have been undertaken in the severe aortic stenosis (AS) population with small aortic annuli. Objectives of the present study are to compare the hemodynamic performance (incidence of severe PPM and ≥ moderate AR) and clinical outcomes (death, stroke, major or life threatening bleeding) between TAVR and SAVR in patients with severe AS and small aortic annuli.

The treatment with transcatheter aortic valve implantation (TAVI) of patients with small (≤23mm) surgical bioprostheses remains a challenge due to the increased transvalvular residual gradients and high rates of severe prosthesis-patient mismatch (PPM) following the procedure.
