Long-Term Outcome of Mustard/Senning Correction for Transposition of the Great Arteries (TGA) in Sweden and Denmark.

The authors evaluated long-term outcomes of 468 patients who have undergone a Mustard- or Senning operation for transposition of the great arteries (TGA). They found that perioperative mortality was 30%, but 60% were still alive after 30 years of follow-up. Perioperative mortality increased with the presence of a ventricular septum defect, early experience with the procedure, and left-ventricular outflow obstruction After patients had survived the postoperative period, only pacemaker implantation was a predictor of long-term outcome (HR=1.90, p=0.04).
