Postpartum dissecting aneurysm of coronary arteries in a patient with sarcoidosis.

We have described a case of sudden death in a 27-year-old woman, 16 days postpartum, resulting from a dissecting aneurysm of the right and left coronary arteries. The patient also had multiorgan sarcoidosis. Postpartum coronary artery dissecting aneurysm appears to be caused by weakening of the media, resulting from the loosening of the ground substance during pregnancy and the hemodynamic changes occurring during and after delivery.
