Significant left main stenosis following asymptomatic dissection during coronary arteriography
Abstract:
The natural history of minimally symptomatic or asymptomatic iatrogenic coronary dissection is not well-defined. While generally considered a serious and life-threatening complication of coronary arteriography, there have been some reported cases of spontaneous resolution without residuals. We describe a case demonstrating that coronary artery dissection, even when initially asymptomatic, may later progress and result in significant or complete coronary occlusion. The implications of this are discussed.

Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
