Abstract:
BACKGROUND: Left main coronary artery (LMCA) angioplasty is another option in the surgical treatment for LMCA disease because of its advantages over the conventional coronary artery bypass grafting (CABG). MATERIAL AND METHOD: Between July 1994 and December 1997, 15 patients underwent left main coronary angioplasty for the stenoses of LMCA. There were 8 males and 7 females with the mean age of 53.3+/-8.8 years. The locations of the LMCA stenoses were proximal one-third of the LMCA in 9, middle one-third in 1, distal one-third in 3, and the whole length of the LMCA in 2 cases. Nine patients had peripheral coronary lesions in addition to the LMCA stenosis. The LMCA was approached anteriorly with or without transsection of the main pulmonary artery. The angioplasty was performed with onlay patch widening using an autologous pericardium (14 cases) or saphenous vein (1 case). Additional graftings were required in 9 cases, and both LMCA angioplasty and right coronary ostial angioplasty were done in 1 case. RESULT: There was no operative mortality. One case needed redo CABG due to the stenosis of the angioplasty site which developed 4 months postoperatively. Coronary angiography was performed in 8 cases one year postoperatively, and revealed good patency of the angioplasty site except for one who showed 50% stenosis at the angioplasty site. No patient complained of angina with a mean follow up of 23+/-11 months. CONCLUSION: Surgical angioplasty of the LMCA stenosis can be performed in selected cases with safety and good mid-term results.
