Percutaneous transluminal coronary angioplasty for ostial stenosis of the left coronary artery--a case report and literature review.

A 11-year-old girl developed left main coronary artery osteal stenosis after Takayasu's arteritis for which she underwent Percutaneous Transluminal Coronary Angioplasty (PTCA). The narrowing of the left coronary artery was successfully dilated by angioplasty without apparent complication. This one suggests that PTCA may have a potential advantage as a temporary method to postpone the aortocoronary bypass surgery in a child with coronary artery stenosis due to Takayasu's arteritis.
