title: Diaphragmatic coronary lesion mimics significant coronary stenosis: a report of four cases.
abstract: Diaphragmatic coronary stenosis is a rare coronary angiographic finding. It gives rise to an appearance of relatively severe obstruction and can lead to unnecessary surgical intervention or PTCA. We described four patients with this type of stenosis in whom the lesions proved to be hemodynamically insignificant as judged by the presence of only minor pressure gradients across them.
