  • Title: Coronary artery dissection - a complication of cardiac catheterization without sequelae: case report and review of the literature.
    Author: Meller J, Friedman S, Dack S, Herman MV.
    Journal: Cathet Cardiovasc Diagn; 1976; 2(3):301-8. PubMed ID: 991267.
    Abstract:
    This report describes an acute right coronary artery dissection occurring during diagnostic cardiac catheterization. Following catheter manipulation in the vicinity of the aortic valve, the patient complained of mild chest discomfort and had transient electrocardiographic evidence of acute inferior wall myocardial infarction with runs of 2:1 atrioventricular block. Within 5 min, the EKG reverted to precatheterization appearance, and the patient was asymptomatic. Coronary angiography revealed a dissection of the proximal vessel without obstruction. The patient had no clinical sequelae while monitored in the intensive care unit. The patient underwent elective aortic and mitral valve replacement. The area of the dissection was directly visualized, and no abnormality was noted. We review the literature of spontaneous and iatrogenic coronary artery dissections with regard to pathology, diagnosis, and prognosis, and make recommendations for therapy.
