Balloon valvuloplasty is safe, equally effective procedure for enlargement of tight and narrow cardiac vales, involving a lesser duration of hospital stay and avoidance of a surgical scar on the body. 

Many a times newborn may have a very tight aortic or pulmonary valve (Critical aortic or pulmonary stenosis), which requires an urgent Balloon aortic or pulmonary valvuloplasty (BAV/BPV) to prevent further damage to the ventricular pumping function. 

Post procedure, the patient needs follow-up at regular intervals.  Balloon dilatation of the mitral valve can also be done in cases of tight mitral stenosis resulting from rheumatic heart disease.
