Residual Plaque Burden

FIGURE 15.28 Residual plaque burden. The IVUS images at baseline (upper) and follow-up (lower) of a patient who developed plaque progression at the proximal reference during 1 year after DES implantation. Minimal neointimal hyperplasia is observed within the stent, whereas obvious plaque progression (yellow arrows in A′) is noted in the proximal reference segment where only mild calcified plaque lesion was observed at baseline. The positions in the cross-sectional and longitudinal views at baseline (A-C) correspond to the A′, B′, and C′ at follow-up. Yellow dotted line tracing lumen and green line tracing stent in longitudinal views. PB, plaque burden.

The ratio of plaque area to total vessel area is termed “plaque burden” (FIGURE 15.28). Residual plaque burden after stenting is known as a major and independent influence on the late outcome.2
