Key result
Prolonged high-pressure balloon inflation significantly improved minimal stent area compared to a rapid inflation sequence (7.83 vs. 6.63 mm2, P=0.0003) and decreased the number of malapposed struts.

Prolonged high-pressure balloon inflation significantly improves stent expansion and strut apposition compared to rapid inflation/deflation during coronary stenting.
Cook et al. (2013) studied Coronary artery disease requiring stenting (n=12). Prolonged high-pressure balloon inflation vs. Rapid inflation/deflation sequence (mean 28 sec) was evaluated on Minimal stent area (mm2) (p=0.0003). Prolonged high-pressure balloon inflation significantly improved minimal stent area compared to a rapid inflation sequence (7.83 vs. 6.63 mm2, P=0.0003) and decreased the number of malapposed struts.
