A transhepatic approach to mitral valvuloplasty is feasible and can be considered when femoral venous access is restricted.
A novel, transhepatic approach to mitral valvuloplasty is described in a patient with an inferior vena caval filter. After transhepatic transseptal puncture, an Inoue dilatation catheter was passed through the hepatic parenchyma and across the atrial septum. Balloon mitral valvuloplasty was performed without complications. This approach should be considered when femoral venous access is restricted or is not feasible.
