[Surveillance of corrected transpositions by the Mustard or Senning operation]

One hundred eighteen patients who survived Mustard immunités (n = 103) or Senning operations (n = 15) performed between 1972 and 1984 for isolated transposition of the main arteries were followed-up for over a mean period of 3.67 yr (up to 12 yr). The authors have examined the potential complications which can alter the long-term prognosis in this type of atrial correction: heart rhythm disorders (regression of sinus rhythm of 3.82% yr), mechanical complications, haemodynamic dysfunction. After atrial correction the survival curve underwent an actuarial regression of 1.3% yr. All these potential complications should be detected by regular survey and may indicate anatomical correction, the results of which have yet to be fully evaluated.
