What this trial studies

This study investigates the safety and efficacy of early versus deferred aortic valve replacement (AVR) in patients who have moderate aortic stenosis combined with moderate mitral regurgitation. It aims to address the lack of data on the timing of intervention for patients with multivalvular heart disease, as current guidelines primarily focus on isolated valvular lesions. The study will involve either transcatheter or surgical AVR, with the timing of intervention based on specific hemodynamic criteria. By exploring these approaches, the study seeks to determine if early intervention can provide better outcomes for patients with this complex condition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with moderate aortic stenosis and moderate mitral regurgitation who meet specific hemodynamic criteria.

Not a fit: Patients with severe valvular heart disease or those with a life expectancy of less than one year are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for patients with combined aortic stenosis and mitral regurgitation, potentially enhancing their quality of life and survival rates.

How similar studies have performed: While there is limited data on the timing of intervention for multivalvular disease, similar studies have shown promise in improving outcomes for patients with isolated valvular lesions.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Age ≥18 years
* Moderate native aortic stenosis defined by an aortic valve area (AVA) ≤1.5 cm2 and \>1.0 cm2 and transvalvular mean gradient ≥20 mmHg and \<40 mmHg.
* Primary or secondary mitral regurgitation (at least moderate) defined by effective regurgitant orifice area (EROA) ≥20 mm2 or regurgitant volume ≥30 ml
* New York Heart Association (NYHA) functional class ≥2

Exclusion Criteria:

* Life expectancy \<1 year irrespective of valvular heart disease
* Left ventricular ejection fraction \<30% or LVESD \>70mm
* Echocardiographic evidence of severe right ventricular dysfunction
* Untreated clinically significant CAD requiring revascularisation
* Moderate or severe aortic regurgitation
* Severe tricuspid valve disease requiring intervention
* Symptomatic patients with severe primary MR who are operable and not high risk
* Patients with severe secondary MR who remain symptomatic despite optimal medical therapy and who are judged appropriate for transcatheter edge-to-edge repair or surgery by the Heart Team

* COPD with home oxygen therapy
* Estimated or measured systolic PAP \>70 mmHg
