Ventilator-assisted transcatheter edge-to-edge mitral valve repair for severe atrial functional mitral regurgitation: a case report.

In patients with AFMR, the sagittal dilation of the MA and asymmetry in the tethering angles of the leaflets often produce a marked coaptation gap, which poses a challenge in MitraClip therapy. In our patient, the ventilator-assisted technique effectively reduced the coaptation gap between the leaflets, thus leading to successful results.
