Pulmonary hypertension - problems and management in peadiatric cardiac surgical patients.
Biomedica Jan ;26(1):85-8.

Pulmonary hypertension is a common occurrence in many congenital heart diseases and the status of the pulmonary vascular bed is the major determinant of clinical manifestations, course, feasibility and outcome of corrective surgery.1 The prognosis of pulmonary hypertension depends mostly on its cause and the stage of pulmonary vascular disease the child is having at the time of diagnosis.2 However it is unclear why one child behaves differently from another with what seem to be the same degree of pulmonary hypertension. Despite this, with better insight into pathophysiology and introduction of newer vasodilator, management of these patients has significantly improved over past decades.3
