ABSTRACT
Balloon pulmonary valvuloplasty was first introduced as an interventional procedure by Kan and colleagues in 1982,1 and is now accepted as the standard therapeutic procedure for valvar pulmonary stenosis.2-4 The procedure can be successfully performed at any age, ranging from a newborn infant with critical pulmonary valve stenosis to the adult population.5 With its excellent results and low rate of procedure-related adverse events, peak instantaneous systolic echo gradients of as little as 35 mmHg, when combined with evidence of right ventricular hypertrophy, should be considered an indication for balloon pulmonary valvuloplasty.6
