Patient had Barlow syndrome with multiple scallops.
†
Unfavorable anatomic characteristics for percutaneous mitral valve repair, (1) valve geometry: coaptation depth ≥11 mm, flail gap >10 mm, coaptation width >15 mm, MVA ≤4.0 cm2, mean gradient ≥5 mmHg; (2) valve anatomy: perforation or cleft, significant calcification in grasping area, commissural pathology, Barlow syndrome with multiple scallop flail.
