Multiple echocardiography abnormalities associated with endoscopic third ventriculostomy failure

OBJECTIVEAlthough endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC) has gained increasing prominence in the management of hydrocephalus caused by intraventricular hemorrhage of prematurity, the rates of long-term shunt independence remain low. Furthermore, limited evidence is available to identify infants who might benefit from the procedure. The authors tested the hypothesis that elevated venous pressure that results from comorbid cardiac disease might predispose patients to ETV/CPC failure and shunt dependence.METHODSA retrospective analysis was performed on a consecutive series of 48 infants with hydrocephalus who underwent ETV/CPC and also underwent preoperative echocardiography between 2007 and 2014. Comorbid cardiac abnormalities that are known to result in elevated right heart pressure were reviewed. Associations between ETV/CPC success and the presence of pulmonary hypertension, right ventricular hypertrophy, left-to-right shunting, ventricular septal defect, or patent...
