Duration of balloon inflation for optimal stent deployment: Five Seconds Is Not Enough

Abstract

The duration of stent balloon inflation has a significant impact on stent expansion. Stent deployment for >25 sec is recommended.

Effect of Stent Inflation Pressure and Post-Dilatation on the Outcome of Coronary Artery Intervention. A Report of More than 90 000 Stent Implantations

“…The SCAAR definition corresponds to definite stent thrombosis but excludes non-occlusive stent thrombosis. The SCAAR does not hold information on the duration of stent inflation, a parameter closely related to proper stent expansion [24]. The ratio between vessel diameter and balloon diameter was not available and neither was the number of post-dilatations.…”

Improved stent expansion with prolonged compared with short balloon inflation: A meta‐analysis

“…To provide a comparison of fixed duration inflation strategies two separate sensitivity analysis were performed—one excluding the study by Cook and the other excluding studies by Cook and Ann. Further, in the studies by Hovasse and Saha, three different inflation times (5, 15, 25 sec and 10, 30, 60 sec, respectively) were evaluated . MSD in the shortest and longest time groups was compared in our meta‐analysis.…”

Impact of Implantation Technique and Plaque Morphology on Strut Embedment and Scaffold Expansion of Polylactide Bioresorbable Scaffold – Insights From ABSORB Japan Trial –

“…17 As for inflation time, Hovasse et al reported that a longer duration of stent balloon inflation (>25 s) significantly improved stent expansion compared with a shorter duration (5 or 15 s). 18 Repeated balloon expansion also improved stent expansion. 19 Kitahara et al recently demonstrated with various metallic platforms assessed by real-time OCT in an in-vitro Accordingly, a dedicated implantation technique needs to be used for implantation of the Absorb BVS to achieve a similar acute performance as the metallic stent.…”
