E. Bruckheier et al., AORTIC-STENOSIS AND PATENT DUCTUS-ARTERIOSUS - PRESSURE-GRADIENTS PRETRANSCATHETER AND POSTTRANSCATHETER DUCTAL OCCLUSION, Pediatric cardiology, 19(5), 1998, pp. 428-430
Three patients with patent ductus arteriosus and moderate aortic steno
sis had a marked reduction in aortic valve gradient following transcat
heter ductal occlusion. The hemodynamic effects of an aortopulmonary s
hunt on the severity of left ventricular outflow obstruction and the i
mplications on intervention are discussed.
