Long-term results of balloon pulmonary valvuloplasty in pediatric age group in surgical specialty teaching hospital/cardiac center/Hawler

Abstract

Congenital  valvular  pulmonary  stenosis  accounts  for  5–10%  of  all congenital heart disease. Balloon pulmonary valvuloplasty is a safe and effective method in reduction of moderate to severe valvular pulmonary stenosis.  This  retrospective  study  done  in  Hawler  surgical  specialty cardiac center on pediatric patients who had pulmonary valve stenosis (with  echocardiographic  peak  gradient  ≥50mmHg)  and  treated  by balloon pulmonary valvuloplasty. 
A total of 178 cases were involved, 93(52.25%) patient was male and 85 (47.75%) patients was female. 160 patient (89.89 %) were treated with single balloon method 18 patient (10.11 %) were managed by double balloon method technique. Follow up period of these patients range from 1 year to 10 years (mean of 5.5 year). In 153 patients (85.96%) pressure across pulmonary valve were below 36 mm Hg, while in 21 (11.80%) pressure gradient across pulmonary valve were (36-50 mm Hg).  Four (2.24%) patients had pressure gradient across pulmonary valve more than 50 mm Hg. Forty patients (22.47%) developed mild pulmonary valve  regurgitation,  while  20  patient  (11.24%)  developed  significant pulmonary valve regurgitation. 
Balloon  pulmonary  valvuloplasty  provides  long-term  relief  of pulmonary valvular obstruction in the majority of pediatric patients. The long-term results are favorable.
