New heart valve fix without surgery shows promise for High-Risk patients
NCT ID NCT03339115
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new device called the Cardiovalve, which is threaded through a blood vessel in the leg to fix a leaky mitral valve without open-heart surgery. It includes 30 people with severe mitral regurgitation who are too high-risk for traditional surgery. The goal is to see if the device is safe and can reduce the backward flow of blood, improving symptoms and quality of life over two years.

General Inclusion Criteria 1. Age ≥ 18 years 2. NYHA functional II, III or ambulatory IV 3. Severe mitral regurgitation (MR grade 3-4+) 4. Subject is on optimal guideline-directed medical therapy for heart failure for at least 30 days or CRT if indicated. 5. Elevated risk for conventional open mitral valve repair or replacement surgery in the consideration of the site Heart Team (including a cardiac surgeon, a cardiologist and imaging specialist as a minimum) based on STS/Euro Score II (per MVARC Part 1), frailty and co-morbidities. 6. Able to undergo Transesophageal Echocardiography (TEE). 7. Subject understands the study requirements and the treatment procedures and provides written Informed Consent before any study-specific tests or procedures are performed. 8. The subject commits to return for the scheduled post-operative follow-up visits at the hospital. Anatomical Inclusion Criteria 9. Suitable for femoral access procedure and trans septal catheterization 10. Native mitral valve geometry and size and LV outflow tract characteristics compatible with the Cardiovalve (as assessed by the independent Screening Committee) Cardiovascular Exclusion Criteria 1. Prior stroke or TIA within 3 months or Modified Rankin Scale ≥4 disability 2. Acute myocardial infarction within the previous 30 days 3. Any prior heart valve surgery or transcatheter mitral intervention 4. Any percutaneous cardiovascular intervention, cardiovascular surgery, or carotid surgery within 30 days 5. Rheumatic heart disease or endocarditis within the previous 3 months 6. Hypertrophic cardiomyopathy, restrictive cardiomyopathy, constrictive pericarditis, or any other structural heart disease causing heart failure other than dilated cardiomyopathy of either ischemic or non-ischemic etiology 7. Existence of inferior vena cava filter or atrial septal device (contraindicating femoral access and transseptal catheterization) 8. Untreated clinically significant coronary artery disease requiring revascularization 9. Tricuspid valve disease requiring surgery or severe tricuspid regurgitation 10. Aortic or pulmonic valve disease requiring surgery 11. CRT/ICD implant within 30 days Anatomical Exclusion Criteria (assessed by pre-procedural imaging) 12. Left Ventricular Ejection Fraction (LVEF) \<30% 13. LV end diastolic diameter \> 70mm 14. Significant abnormalities of the mitral valve and sub-valvular apparatus. 15. Severe mitral annular or leaflets calcification 16. Left atrial or LV thrombus or vegetation 17. Severe right ventricular dysfunction 18. Severe tricuspid or aortic valve disease General Exclusion Criteria 19. Subject who is currently participating in an investigational study, other than this study 20. Hemodynamic instability defined as systolic pressure \< 90mmHg or the need for inotropic support or intra-aortic balloon pump or other hemodynamic support device, or any mechanical heart assistance 21. Subject has contrast agent hypersensitivity that cannot be adequately pre-medicated, has an allergy to Nitinol alloys (nickel and titanium), or has intolerance to antiplatelet, anticoagulant, or thrombolytic medications 22.

Subject with hepatic insufficiency 28. Subject has a co-morbid illness that may result in a life expectancy of less than one year 29. Active infection that requires antibiotic therapy 30. Subject is pregnant, breastfeeding or intend to become pregnant within one year
