Percutaneous pulmonary valvuloplasty is the preferred method for treating pulmonary valve stenosis, particularly in children, and this study aimed to evaluate its effectiveness and long-term outcomes.
The study involved 53 patients, assessing their heart function and valve performance over a median follow-up period of 15 years; it found a significant decrease in transvalvular pressure gradients and low rates of complications.
Results indicated that most patients experienced some degree of late pulmonary regurgitation, but overall, the procedure was successful with minimal long-term issues, and no patients required further surgery.
