Persistent pulmonary hypertension signals severe late morbidity after neonatal aortic valvotomy; leaves open its incidence and surveillance needs.
Case Report (n=4)
Persistent pulmonary hypertension is a previously unreported late complication of successful biventricular repair for neonatal critical aortic stenosis that causes severe morbidity and mortality.
Michael Burch (2004) conducted a case report in Critical aortic stenosis with persistent pulmonary hypertension (n=4). Neonatal aortic valvotomy was evaluated on Late complications (death or severe limitation of effort tolerance). Among four medium-term survivors of neonatal valvotomy for critical aortic stenosis who developed persistent pulmonary hypertension, one died at age 4 and three had severe limitation of effort tolerance.
