Introduction:

balloon valvuloplasty is currently the first line therapy in neonates with critical pulmonary valve stenosis, considered a less invasive procedure, with a lower risk of complications and death compared to surgery.

Objective:

to define the clinical and hemodynamic characteristics of patients with this pathology, who underwent balloon valvuloplasty and its immediate and short-term outcomes.

Method:

retrospective follow-up study of cohort, in a cardiovascular referral center.

Results:

a high percentage of successful valvuloplasty was evident, with a significant decrease in the transvalvular gradient and in the systolic pressure of the right ventricle (RV), with few complications, due to rhythm disturbances and infundibular rupture, without major clinical repercussions. In general, severe infundibular reactions occurred in low frequency and mortality related to the interventional procedure was nil.

Conclusion:

balloon valvuloplasty is an effective and safe procedure for the treatment of neonates with critical pulmonary valve stenosis, with good immediate and short-term results.
