Predictors of RV Dysfunction After BPV

Pulmonary balloon valvuloplasty (PBV) is the treatment of choice for moderate to severe valvular pulmonary stenosis. It is a minimally invasive, catheter-based intervention that involves dilation of the stenotic pulmonary valve using an appropriately sized balloon. The goal is to relieve obstruction, reduce right ventricular pressure, and prevent long-term complications such as RV hypertrophy, dysfunction, and arrhythmias. The procedure has shown excellent immediate and long-term outcomes, particularly in patients with a pliable, doming pulmonary valve and no significant regurgitation or associated congenital lesions.
