Background:
Conventional pulmonary artery banding (CPAB) is associated with high morbidity and mortality. We studied the changes in outcome with the use of an adjustable pulmonary artery band (APAB).
Methods:
Between June 2001 and June 2006, 147 patients underwent PAB: 91 underwent CPAB and 56 underwent APAB.
Results:
The clinical profile of patients was similar in both groups. Inotropic drugs were used in 91 (100%) patients in the CPAB group and in 12 (21%) in the APAB group (p < 0.001). Early band related reoperation was required in 17 patients in the CPAB group compared with 2 patients in the APAB group (p = 0.014). There were 21 (23%) early deaths in CPAB group compared with 1 (1.8%) in the APAB group (p < 0.001). There was no difference in the intensive care unit stay, hospital stay, and final band gradients in the two groups. On a mean follow-up of 22.8 +/- 18.6 months (range, 4 to 72 months), there was PA distortion in 6 patients and band-migration in 4 patients in the CPAB group. These were not observed in the APAB group.
Conclusions:
Similar band gradients were achieved with the use of conventional or adjustable PAB. However, the use of this simple and inexpensive technique of APAB was associated with a significant reduction in the early band-related deaths, need for early multiple reoperations, and early adverse acute events, thus making it a safer alternative to CPAB, more so in unstable patients.
