[Results of arterial switch operation for transposition of great arteries with regard to coronary pattern].
One of the factors determing the postoperative results of arterial switch operation (ASO) for complete transposition of great arteries (TGA) is coronary event (CE). We analyzed the risk factors of CE after ASO in patients whose coronary patterns excluding Shaher type 1. The subjects were 44 patients operated from 1994 to 2007. As for the coronary reconstructive technique, procedures by Mee or Aubert were conducted on patients with Shaher 5A intramural type. The conventional technique was conducted on other patients, with or without trapdoor technique. In all patients, the pulmonary artery was reconstructed mainly with autopericardium using Lecompt maneuver. The mean observation period was 4.0 +/- 3.1 years, and the number of patients showing CE was 14 (32%) at 1.6 years after surgery on the average. The risk factors of CE and the operative procedures were discussed.
