ABSTRACT

High-or low-pressure inflations with direct stenting? In all the reported experiences of direct stenting, the deployment pressures used have been in the high range (14-16 atm). Using high-pressure inflation during initial deployment makes for a quicker, easier and, indeed, safer procedure, since the balloon has essentialy the same length as the stent. It reduces the need to return with additional non-compliant shorter balloons to as low as 4-6%, and generally occurs in vessels that demonstrate distal tapering.23,36 At this stage, high pressure inflations of an optimal diameter device suggest a sub-optimal outcome only in small vessel stenting where contradictory preliminary evidence has been seen.
