The aim of this study was to assess the immediate results of percutaneous balloon valvuloplasty in all age groups diagnosed with critical pulmonary valve stenosis in a tertiary-care setting.
A retrospective cross sectional analysis of all consecutive patients from neonatal to adult age group who underwent percutaneous balloon valvuloplasty for critical pulmonary valve stenosis from Aug 2010 to Dec 2015 at AFIC/NIHD was done.
Congenital isolated pulmonary valve stenosis is one of the first congenital cardiac defect for which balloon valvuloplasty has become the treatment of choice and preferred therapeutic alternative3-6 in all age groups regardless of valve morphology28.

There are various definitions of severity grading, but there is general agreement that transvalvular peak systolic pressure gradient <25 mmHg is trivial; 25 to 49 mmHg, mild; 50 to 79 mmHg, moderate;_ 80 mmHg, severe17.It is generally believed that indications for balloon pulmonary valvuloplasty are similar to those used for surgical pulmonary valvotomy, i.e., a moderate degree of pulmonary valve stenosis with a peak to peak gradient [greater than or equal to] 50 mmHg with normal cardiac index18.
