About this trial

This trial is a randomized study for patients with significant atrial functional mitral regurgitation (AFMR) and atrial fibrillation (AF). The composite endpoint of all-cause mortality, cardiovascular-related hospitalizations, AF recurrence, and quality of life improvement is hypothesized to be superior with the combination of transcatheter edge-to-edge repair (TEER) and catheter ablation, compared with catheter ablation alone.

Eligibility criteria

Qualifiers

Age ≥ 18 years

Left ventricular ejection fraction ≥ 50%

Grading of MR: 3+ or 4+ (effective regurgitant orifice area≥30mm2, regurgitant volume ≥45ml)

Valve morphology: MR originating from the mid portion of the valve; mitral valve area> 4 cm2; Length of posterior leaflet ≥10 mm; Sufficient leaflet tissue for mechanical coaptation: coaptation depth< 11 mm, coaptation length> 2 mm

Disqualifiers

Life expectancy< 1 year due to non-cardiac conditions

Primary mitral regurgitation: valve abnormalities including leaflet tethering from LV dysfunction, intrinsic leaflet pathology (prolapse, flail, calcification, severe thickening), mitral annular calcification (either severe or <severe but extending into the leaflets), and/or any mixed pathology

Active endocarditis of the mitral valve or rheumatic mitral valve disease

Hypotension (systolic pressure < 90 mmHg) or requirement for inotropic support or mechanical hemodynamic support
