title: Percutaneous balloon pulmonary valvuloplasty: a modified over-the-wire Inoue balloon technique for difficult right ventricular anatomy.
abstract: Percutaneous balloon pulmonary valvuloplasty (BPV) is the mainstay of treatment for significant pulmonary stenosis with doming leaflets. Various techniques have been described in the literature including the use of Inoue Percutaneous Transseptal Mitral Commissurotomy (PTMC) catheter with standard 0.025″ guidewire. But if right ventricular anatomy is not suitable, 0.025″ guidewire doesn't provide enough support to track the Inoue PTMC catheter. Here, we report a case of successful BPV using a novel technique of slenderizing the Inoue Percutaneous Transseptal Mitral Commissurotomy (PTMC) catheter over an Amplatz superstiff 0.035″ guidewire. This technique may be useful during BPV in difficult right ventricular inflow and outflow tract anatomy in patients with congenital pulmonary valve stenosis.
