Pseudoaneurysm following successful excimer laser coronary angioplasty of a restenotic left internal mammary artery graft ostial lesion.

Although significant left internal mammary artery graft ostial stenosis is extremely rare, the clinical importance can be profound. In this report we describe a case in which a restenotic left internal mammary artery graft ostial lesion was successfully opened with excimer laser coronary angioplasty. A resulting pseudoaneurysm spontaneously closed after conservative therapy.
