Aneurysm of the right colic artery

Primary PTCA as a means of reestablishing coronary blood flow in the infarct related artery is preferable in certain subgroups of patients with acute myocardial infarction. While the success rate of primary PTCA is very high, the procedure is not without risk. We report a case of hemodynamic collapse during PTCA due to an Amplatz guide catheter-induced, acute, and reversible aortic insufficiency. With the increasing use of the left Amplatz catheter for better guide support during PTCA, this unusual and previously unreported complication should be borne in mind.
