Pulmonary Artery Dissection and Rupture in Eisenmenger's Syndrome

A patient with ventricular septal defect and pulmonary arterial hypertension (Eisenmenger's syndrome) associated with aortic coarctation with follow-up for 19 years, and with rupture of an aneurysmatic pulmonary artery is described. An incident of extreme fright with a possible transient systemic hypertension may have precipitated the dissection of the pulmonary arterial intima and the rupture.
