Appraisal of the Mustard procedure for the physiological correction of "simple" XXXX . Eighty consecutive cases, 1970-1980.

Eighty successive @entity1 underwent the Mustard operation for "simple" @entity3886 (TGA) between January, 1970, and January, 1980. Ages ranged from 42 days to 12.4 years (mean 14.7 months). Balloon atrial septostomy (BAS) with balloon volumes of more than 2.5 ml produced significant increases of arterial @entity26 saturation, although the initial benefit of BAS was greater than that found at follow-up catheterization. In these @entity1 the left ventricular (LV) pressure tended to decrease during the first months of life, but this drop was less marked at the end of the first year. Deep @entity2332 and @entity1167 were employed in all cases. Several modifications were adapted to the original surgical technique in order to reduce last sequelae. There were two early and three late deaths. At follow-up (mean 4.5 years) 74% of @entity1 were symptom free. Sinoatrial and atrioventricular (AV) conduction disturbances were present in five and six @entity1 , respectively. Caval or @entity3885 occurred in 13 @entity1 , seven of whom required reoperation. Isolated @entity997 was present in one @entity1 only, but in four it was associated with other defects. Primary right ventricular (RV) failure occurred in one @entity1 . These findings, in relation to mortality, complications, and the excellent clinical results in the majority of survivors, compare favorably with results published for @entity1 with "simple" TGA who have been subjected to other types of physiological or anatomic correction. At the present time, there seems to be no good reason to alter our surgical policy in this group of @entity1 .
