The MITRAL II Pivotal Trial for Mitral Valve Disease

This study is for people aged 18 or older with severe mitral annular calcification (calcium buildup in the heart valve) and symptomatic mitral valve dysfunction, meaning your mitral valve isn't working well. This includes severe mitral stenosis (narrowing of the valve) or moderate to severe mitral regurgitation (leaky valve). The study is testing the safety and effectiveness of the Edwards SAPIEN 3, SAPIEN 3 Ultra, and SAPIEN 3 Ultra RESILIA valves, delivered using a transseptal (through the wall between heart chambers) approach, for patients who cannot have standard surgery. Success will be measured by looking at all-cause mortality (death from any cause) and hospitalization for heart failure at one year. The current recruitment status is unclear, with a planned enrollment of 210 participants.

Study design
This is a prospective multicenter study with two groups: one receiving the transseptal ViMAC procedure (110 patients) and another receiving medical treatment only (up to 100 patients).
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for at least one year to assess all-cause mortality and hospitalization for heart failure.

Eligibility criteria

Exclusion

Native neo mitral annulus size \< 275 mm2 or \> 810 mm2 as measured by CT scan.
Significant risk of LVOT obstruction or valve embolization as assessed by CT core lab 17. Clinically (by neurologist) or neuroimaging confirmed stroke or transient ischemic attack (TIA) within 90 days of the procedure. 18. Estimated life expectancy \<12 months due to non-cardiac conditions. 19. Expectation that patient will not improve despite treatment of mitral valve dysfunction. 20. Active bacterial endocarditis within 180 days of procedure. 21. \- Severe right ventricular dysfunction as assessed by Echo core lab 22. \- Active infection requiring antibiotic therapy (subject may be a candidate after 2 weeks of antibiotic discontinuation. 23. \- Female who is pregnant or lactating. 24. \- Participating in another investigational device study. 25. \- Aortic valve disease requiring intervention. If aortic valve intervention is required, the AVR procedure should be performed first and if the patient remains symptomatic after AVR, may be presented for consideration for inclusion in this trial. 26. \- Severe fixed pulmonary hypertension (PASP ≥70 mmHg and more than 2/3 of the systemic systolic blood pressure). 27. \- Severe chronic obstructive pulmonary disease requiring continuous home oxygen. 28. \- The patient refuses mitral valve intervention 29. \- Recent symptomatic COVID-19 infection with residual symptoms that may affect the outcomes of this trial.
