Percutaneous transluminal coronary angioplasty guidewire-induced coronary artery dissection without balloon inflation.
A case of arterial dissection of the right coronary artery secondary to angioplasty guidewire manipulation is presented. No balloon inflation was performed. The histologic appearance of the involved arterial segment was similar to that found in the left anterior descending coronary artery, which had undergone successful balloon dilatation. Both arteries demonstrated medial disruption and fibrointimal proliferation. The pathologic features of angioplasty-induced vascular injury may occur with or without balloon inflation.
