Occurrence of a saccular pseudoaneurysm formation two weeks after perforation of the left anterior descending coronary artery during balloon angioplasty in acute myocardial infarction.

We describe the occurrence of a localized saccular pseudoaneurysm in a 69-year-old patient 2 weeks after perforation of the left anterior descending coronary artery during balloon angioplasty in acute myocardial infarction. The therapy of perforations requires prolonged balloon inflations, perfusion balloons, covered stents, or surgery. Coronary peudoaneurysm formations are rare; their therapy requires covered stents or surgery. Cathet. Cardiovasc. Intervent. 47:341-346, 1999. Copyright 1999 Wiley-Liss, Inc.
