title: Successful inoue balloon valvotomy in a difficult case of mitral stenosis using multiple modifications of technique: alternative method for loop formation of the Inoue balloon catheter.
abstract: Transseptal puncture was accomplished with difficulty at an unfavorable site in a case of severe mitral stenosis with distorted atrial and septal anatomy. Septal balloon entrapment could not be avoided during attempts to cross the mitral valve using the standard technique. This problem was circumvented by resorting to the loop method and the left ventricle was entered first with a guidewire, which then supported the balloon catheter. Successful mitral valve dilatation could thus be performed. A simple alternative method that was used to form the Inoue balloon catheter into a loop is also described.
