Abstract
Sick sinus syndrome is a frequent complication following Mustard operation. Between October 1971 and May 1985, we performed the Mustard operation on 78 patients with transposition of the great arteries. Sixty-six patients were followed long-term for up to 10 years after surgery. We reviewed patient records and Holter monitor recordings in these latter 66 patients to determine if the degree of bradycardia predicted symptoms requiring permanent pacing. A total of 8/66 patients received pacemakers. Indications for pacing included asymptomatic bradycardia during the first postoperative month, symptomatic bradycardia (seizures and syncope) late following surgery, and use of antiarrhythmic drugs other than digoxin for the control of symptomatic atrial flutter or supraventricular tachycardia. The mean minimal heart rates documented by Holter monitor recordings did not differ significantly between the asymptomatic and symptomatic patients (p 0.15). We conclude that the degree of bradycardia is not a reliable predictor of symptoms or the need for pacing in postoperative Mustard patients during early and intermediate duration follow-up.
