We report a case of a 72-year-old woman, who had an anastomotic pseudoaneurysm in the ascending aorta, successfully treated by endovascular aortic repair with vascular embolic devise and stent-graft. It seemed to be high risk to achieve conventional surgery with extracorporeal circulation, therefore we selected endovascular treatment because she had a bleeding tendency which derived from disseminated intravascular coagulation. Then, we adopted stent-grafting with a vascular embolic device, because the distal side of pseudoaneurysm had too short a landing zone to cover the stent-graft only. The patient well tolerated this procedure and her postoperative course was uneventful. The pseudoaneurysm shrank at 6th months after operation.

“Cardiac Cycle: The First Step, ” which discretely, non-ambiguously, and accurately presents basic essential information on the cardiac cycle, was compared with conventional material in terms of educational efficiency. Twenty-six first-year medical students were randomly assigned to either material. The conventional group was presented with a standard textbook with a typical figure and text. The students were blinded as to the origin of the materials. After self-study, the same quiz (30 two-item choice questions asking basic essential information) was given to both groups and was scored by a blinded rater. The number of correct answers was 25.7±3.7 (mean±SD) in the conventional group and 29.4±1.1 in the ‘first-step group’(p<0.01).
