Three cases of LMCAP for the isolated LMCA stenosis were presentd. In two cases of the proximal LMCA stenosis, the connective tissue between the ascending aorta and the main pulmonary artery was prepared to detect the LMCA. From the left lateral wall of the ascending aorta to the anterior wall of the LMCA over the stenotic lesion was excised and the saphenous vein patch was sutured (anterior approach). In the third case, because the stenosis was locarized at the distal LMCA, the patch angioplasty using the saphenous vein was performed by direct opening of the distal LMCA accessed from the left lateral side of the main pulmonary artery without aortotomy (lateral approach). Ultrasonic cuser was quite useful to isolate the LMCA. LA-LV vent was indispensable to obtain the non-blood clean operation field. All three cases showed the successful enlargement of LMCA at the postopeorative coronary angiography.
