Left atrial V‐wave pressure reduction according to flail leaflet, number of jets, and 3‐dimensional (3D) echocardiographic image quality. Significant reduction in the V‐wave was observed in patients with (38±15 vs 24±10 mm Hg; P<0.001) and without (38±13 vs 30±9 mm Hg; P<0.001) a flail leaflet (A). Patients with a flail leaflet had a significantly larger reduction in the left atrial V‐wave compared with those without a flail leaflet (P=0.007). Significant reduction was also seen in all groups when stratified by number and location of regurgitant jets (B) and 3D echocardiographic image quality (C). Similar mean reduction in V‐wave was seen in patients with a single vs multiple jets (P=0.56) and fair vs high‐quality 3D echocardiographic image quality (P=0.31).
