Abstract
We compared the prevalence of arrhythmias among the first consecutive 45 patients with complete transposition (concordant atrioventricular and discordant ventriculo-arterial connexions) after arterial switch operation and the last 47 patients after Mustard repair in infancy. Both groups had 24-hour Holter electrocardiographic studies at similar periods of follow up (24 +/- 14 and 25 +/- 18 months). A second group of patients undergoing the Mustard procedure had been repaired at an older age before 1981. They were studied to determine the frequency of disturbances of rhythm during later postoperative follow-up (85 +/- 24 months). Symptomatic brady-/tachyarrhythmia syndrome never occurred after the arterial switch and only once in the group of patients repaired by the Mustard procedure in infancy, but developed at a late stage (69 +/- 28 months); five times in the group of patients having Mustard's repair at an older age. In addition, Holter monitoring did not detect bradyarrhythmias indicating sinus node dysfunction in a single patient after the arterial switch, but did so to a similar extent in both groups having the Mustard procedure (recent: n = 14; older: n = 18). Three cases of the group of older patients undergoing a Mustard operation developed complete atrioventricular block during follow-up. Normal findings were present in 93% of the cases after arterial switch, but in only 51% of the cases with a similar follow-up repaired by the Mustard procedure, and in 29% of the group having the Mustard repair at an older age.(ABSTRACT TRUNCATED AT 250 WORDS)
