A 26-year-old male presented with increasing dyspnoea and exertional palpitations of 2 months duration. The clinical and echo evaluation revealed severe stenosis of the mitral, aortic, and tricuspid valves. Concurrent percutaneous dilatation of all three valves was done as a single stage procedure. The procedure was successful and produced significant clinical and haemodynamic improvement. The mitral and tricuspid valves were dilated using the same Inoue balloon, whereas the aortic stenosis was dilated using the pigtail tipped balloon.
