Palliative mustard operation for transposition of the great arteries: Late results after 15–20 years

Abstract

3/4), haemoptysis, and atrial flutter, eight were well (ability index 2), and one disabled (ability index 3). Arterial oxygen saturation at rest was 85-98% (mean (SD) 93'8 (4)%) decreasing to 59-87% (mean 77 (9.5)%) after limited exercise. Symptomatic arrhythmias occurred in four patients, atrial flutter being the most common, and two had sinus node dysfunction. Significant tricuspid regurgitation occurred in four patients. Conclusion-Patients with palliative Mustard operation have a low incidence of symptomatic ventricular dysfunction and despite exercise limitation by hypoxia, continue to live active, near normal lives until their thirties.
