The Committee noted that conditions needing pulmonary artery banding are rare and large randomised studies would therefore be impractical. This consideration underpinned the recommendation for data collection as a way of providing information for review of the procedure.
The Committee noted that the UK Central Cardiac Audit Database collects data on pulmonary artery banding but does not currently distinguish between the different kinds of pulmonary artery banding. It was advised that steps could be taken to enable data on telemetric adjustable banding to be recorded with the type of banding identified.
