Image quality as assessed by proportion of CIS showed no significant difference between the contrast media and pentastarch (98.4% vs. 97.6%; p=0.846). Pixel-wise blood flushing capability correlated well between the paired image segments (p<0.001; Figure). Quantitative measurements of minimal stent area (7.24 ± 0.85 vs. 7.19 ± 0.74; p=0.769), minimal lumen area (3.15 ± 0.54 vs. 3.11 ± 0.49; p=0.716) showed no significant difference between the paired OCT runs. There were no clinically relevant complications associated with OCT imaging with pentastarch administration such as anaphylactic reaction, life-threatening arrhythmia, heart failure, or acute renal deterioration.
