NCT05909748

Brief Summary

The main objective of this study is to evaluate the feasibility and safety of the GEMINUS system in patients with severe symptomatic aortic stenosis. This is a prospective, open label, multicentre, single arm, first in human clinical study. Clinical follow up for all patients will be performed at 30 days, 6 months, 1, 2, 3, 4 and 5 years post-implantation

Study Arms (1)

GEMINUS Transcatheter Aortic Valve Implantation system

EXPERIMENTAL

Clinical follow up for all patients will be performed at 30 days, 6 months, 1, 2, 3, 4 and 5 years post-implantation

Device: GEMINUS Transcatheter Aortic Valve Implantation system

Interventions

Also known as: GEMINUS TAVI system
GEMINUS Transcatheter Aortic Valve Implantation system

Eligibility Criteria

Age18 Years - 120 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age ≥ 18 years
  • Patient understands the implications of participating in the study and provides informed consent
  • Patient is willing to comply with specified follow-up evaluation
  • Severe aortic stenosis as per ACC/AHA 2020 guidelines (e.g. AVA ≤ 1.0 cm2 (or AVA index ≤ 0.6cm2/m2)\* AND PV ≥ 4 m/sec or mean gradient ≥ 40 mmHg)\*\* as determined by TTE/CT-TAVI
  • \*May be larger with mixed AS/AR
  • \*\*For low flow low gradient AS or paradoxical low flow severe AS must meet ACC/AHA guidelines (table 13 stages of AS in the guideline)
  • Cardiac Symptoms: ≥ NYHA Class II
  • Patient ≥ intermediate surgical risk as assessed by the heart team or ≥75 years old.
  • Aortic annulus diameter ≥22 mm and \< 29 mm, assessed by CT TAVI
  • Anatomically suitable for implantation of the GEMINUS device
  • Peripheral vessels (common femoral and iliac arteries) of acceptable size (minimal diameter \> 4mm), tortuosity, and calcification to accommodate the 12Fr catheter system.
  • Patients assessed by the heart team to be at high risk for access site related bleeding/vascular complications due to the caliber/ calcification/ atherosclerosis of the iliofemoral vessels.

You may not qualify if:

  • Patient not suitable for surgical bailout
  • Congenital uni/bi/quadricuspid valve, or noncalcified aortic valve.
  • Mixed aortic valve disease (aortic stenosis and aortic regurgitation with predominant aortic regurgitation ≥3+).
  • Active or recent (within 6 months) endocarditis.
  • Active systemic infections.
  • Recent MI (≤ 1 month).
  • Any therapeutic invasive cardiac procedure (except BAV) performed within 30 days of the index procedure.
  • Prosthetic heart valve in any position.
  • Severe (\> 3+) mitral, tricuspid or pulmonic regurgitation.
  • Blood dyscrasias as defined: leukopenia (WBC\<3000/mm3), acute anemia (Hb \<8mg%), thrombocytopenia (platelet count \<50,000 cells/mm3), history of bleeding diathesis or coagulopathy.
  • Untreated clinically significant coronary artery disease requiring revascularization.
  • Hemodynamic instability requiring inotropic support or mechanical support devices.
  • Hypertrophic cardiomyopathy with or without obstruction (HCM).
  • Severe ventricular dysfunction with left ventricular ejection fraction (LVEF) \<20%.
  • Echocardiographic evidence of intracardiac mass, thrombus or vegetation.
  • +7 more criteria
