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
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
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.
Percutaneous plumonary valvuloplasty is effective procedure of first choice in treatment neonates and infants with critical plumonary stenosis
