Abstract

ABSTRACT:
BACKGROUD:
Critical plumonary valve stenosis represents an emergency and immediate treatment is mandatory. Percutaneous plumonary valvuloplasty is the treatment of choice for isolated plumonary valve stenosis
OBJECTIVE:
Results and complications, of this procedure in our cath. Lab.
PATIENTS AND METHODS:
From January 2006 to August 2009, 28 neonates and infants with critical plumonary valve stenosis (mean age 33.5 days : range 6-88 days) underwent percutenous plumonary valvulopalsty. All patients were cyanosed, and the clinical diagnosis was confirmed by cross sectional and Doppler echocardiography
RESULTS:
The plumonary valve was successfully crossed in all patients. The trasvalvular gradient dropped from 86.9+_21mmgh to 33.2+_20.9mmgh, the mean right ventricular systolic pressure dropped from 100.4+_2o.7mmgh to 54.2+_20.9mmgh, and oxygen saturation increased from 81+_8% to 97+_2% .There were 9(32.1%) major complication including 4(14.2%) death ,3(10.7%) hemopericardium reguiring drainge and transfusion, and two(7.1%) patients developed considerable venous congesation . During a mean followup of 1.6 years , 19(86.3%) of the 22 patients remain free of important restenosis.
CONCLUSION:
Percutaneous plumonary valvuloplasty is effective procedure of first choice in treatment neonates and infants with critical plumonary stenosis
