Catheter-induced coronary artery dissection: The role of exhalation during contrast medium injection

Publication date: Available online 2 July 2018Source: Cor et VasaAuthor(s): Andreas Y. AndreouAbstractCatheter-induced dissection of the coronary arteries is an uncommon but potentially dreadful complication of diagnostic and interventional coronary procedures. Several risk factors have been implicated in the development of this complication; one of them is deep vigorous inhalation inducing a change in catheter position thereby contributing to catheter-induced coronary artery dissection. The present article describes a case of catheter-induced right coronary artery dissection where a change in catheter position induced by active patient exhalation contributed to the development of dissection. To the best of my knowledge this is the first case implicating active exhalation in the pathophysiology of catheter-induced coronary artery dissection.
