Pulmonary hypertensive necrotizing arteritis: an unusual case of unilateral involvement in an infant with congenital heart disease.
Pulmonary hypertension is clinically defined as a pulmonary arterial pressure greater than 25 mmHg at rest or greater than 30 mmHg during exercise. We report a unique case of an infant with congenital heart disease causing pulmonary hypertension and necrotizing pulmonary arteritis but affecting only one lung. In conclusion, in pulmonary valve atresia, the lungs may be supplied via aortopulmonary collaterals. Necrotizing pulmonary arteritis is a severe lesion seen in irreversible pulmonary hypertension.
