Concurrent dissections of ascending aorta and right coronary artery during primary coronary angioplasty.

We present a case of dissection in ascending aorta (AA) accompanying dissection of the right coronary artery (RCA) during transfemoral primary coronary angioplasty (PCA) for acute inferior myocardial infarction (MI). To our best knowledge, this is the first case of dissection both in AA and RCA during angioplasty for acute MI. The dissection in RCA was caused by balloon inflation during PCA. Most probably, an angiographically invisible retro-dissection in RCA resulted in the dissection in AA. A computed tomography (CT) confirmed the diagnosis of aortic dissection that was restrained in AA. The patient was treated conservatively. Five days after the event, a control CT demonstrated that the false lumen in AA disappeared and the dissection was healed entirely.
