Extensive patch angioplasty of the left main ostial stenosis using a rhombic-shaped pulmonary autograft.

A rhombic shaped pulmonary autograft patch was applied to enlarge an ostial stenosis of the left main coronary artery (LMCA) in a 25-year-old woman diagnosed with vasculitis syndrome. The patch increased the width of the ostial stenosis and made a funnel-shaped connection. At eighteen months of follow-up, a coronary angiogram by computed tomography showed no restenosis at the LMCA. The rhombic-shaped pulmonary autograft patch might be an ideal shape and material for angioplasty of the ostial stenosis of the LMCA.
