Abstract
Surgical angioplasty of the left main coronary artery for severe ostial stenosis in a thirty-five-year-old oriental woman suffering from Takayasu's disease was performed by use of an onlay autologous pericardial patch through an anterior aortotomy approach. This procedure was performed to reestablish a physiologic antegrade coronary arterial flow and to avoid use of internal mammary arteries, which have little flow in Takayasu's disease, or the saphenous veins, which can also be involved in the inflammatory process. The procedure also avoids a lengthy, time-consuming triple coronary artery bypass procedure and the use of saphenous veins, which are prone to certain slow or rapid attrition.
Total clinical improvement with disappearance of angina and return of the patient to NYHA functional class I with normal treadmill exercise response was immediately obtained. Angiographic restudy six months after the surgical angioplasty revealed excellent results with complete wide patency of the ostium. This represents the first report in the world literature of surgical angioplasty of a left main coronary arterial ostial stenosis in Takayasu's disease.
