ABSTRACT

BACKGROUND:

Anatomic correction of the transposition of the great arteries (TGA) or Taussig-Bing anomaly by means of the arterial switch operation is now accepted as the therapeutic method of choice. This retrospective study was conducted to evaluate the risk factors for operative deaths and the efficacy of technical modification of the coronary transfer. MATERIAL AND

METHOD:

85 arterial switch operations for TGA or Taussig-Bing anomaly which were performed by one surgeon from 1994 to July 2002 at Dong-A university hospital were included in this retrospective study. Multivariate analysis of perioperative variables for operative mortality including technical modification of the coronary transfer was performed.

RESULT:

Overall postoperative hospital mortality was 20.0% (17/85). The mortality before 1998 was 31.0% (13/42), but reduced to 9.3% (4/43) from 1998. The mortality in the patients with arch anomaly was 61.5% (8/13), but 12.5% (9/72) in those without arch anomaly. In patients who underwent an open coronary reimplantation technique, the operative mortality was 28.1% (18/64), but 4.8% (1/21) in patients undergoing a technique of reimplantation coronary buttons after neoarotic reconstruction. Risk factors for operative death from multivariated analysis were cardiopulmonary bypass time (> = or 250 minutes), aortic cross-clamping time (> = or 150 minutes), aortic arch anomaly, preoperative event, and open coronary reimplantation technique.

CONCLUSION:

Operative mortality has been reduced with time. Aortic arch anomaly and preoperative events were important risk factors for postoperative mortality. However atypical coronary artery patterns did not work as risk factors. We think that the technical modification of coronary artery transfer played an important role in reducing the postoperative mortality of arterial switch operation.
