A case series illustrating the utility of ‘over the wire’ technique and its modifications during percutaneous transvenous mitral commissurotomy

The efficacy and safety of percutaneous transvenous mitral commissurotomy by the Inoue technique, in patients with rheumatic mitral stenosis is well known. However, presence of left atrial/appendage thrombus or difficult LV entry entails the use of ‘over the wire’(OTW)technique.
