Critical pulmonary stenosis with a diminutive right ventricle in neonates.
Thirteen of 19 neonates seen in the first months of life with critical pulmonary stenosis (PS) and an intact ventricular septum had a diminutive right ventricle (RV) evidenced by electrocardiographic and angiocardiographic criteria. All were critically ill and at catheterization had hypoxemia secondary to right-to-left shunting at the atrial level, and RV hypertension. Right ventricular angiogr...
متن کاملTreatment of 44 Cases With Lumbar Spine Stenosis and Degenerative Instability: Outcomes of Surgical Intervention
Background and Aim: Degenerative lumbar spine disease can lead to lumbar spine instability. The patients can present with Low Back Pain (LBP), radicular pain, and motor and sensory dysfunction. Age >50, female sex and pregnancies are among prevalent risk factors. The degeneration process usually starts from the intervertebral discs progressing to involve facet joints, ligaments, and vertebral b...
متن کاملPredictors of survival in neonates with critical aortic stenosis.
BACKGROUND Failure of infants with critical aortic stenosis to survive after adequate valvotomy despite a left ventricular size that appears to be adequate indicates that additional preoperative anatomic features may contribute to mortality. METHODS AND RESULTS Discriminant analysis was used to determine which of several echocardiographically measured left heart structures were independent pr...
متن کاملBalloon dilatation of critical stenosis of the pulmonary valve in neonates.
Percutaneous balloon dilatation was attempted in 15 consecutive neonates (mean age 7.3 (range 1-27) days and weight 3.2 (range 2.5-4.1) kg) with critical stenosis of the pulmonary valve. Dilatation was successful in 11 (73%) patients. The mean balloon to annulus ratio was 1.1 (range 0.6-1.77). The ratio of right ventricle to femoral artery systolic pressure decreased from a mean (1 SD) of 1.4 (...
متن کاملEvolving management for critical pulmonary stenosis in neonates and young infants.
Over the years, management of critical pulmonary stenosis in young infants has evolved from surgical reconstruction of the right ventricular outflow tract and closed pulmonary valvotomy to transcatheter balloon valvoplasty. Our study aimed at evaluating how the changing policy for management had affected the immediate and long term outcomes of babies with this cardiac lesion. Interventions were...
