Abstract
The aim of this study was to compare the
detection rate of tissue prolapse (TP) in optical coherence
tomography (OCT) and intravascular ultrasound (IVUS)
after drug-eluting stent (DES) implantation and evaluate
clinical implication of TP at 2 years after percutaneous
coronary intervention. In spite of the superiority of OCT in
the aspect of resolution when it was compared to IVUS,
there was little data about the superiority of OCT in
detecting TP. And there has been controversy about the
clinical significance of TP. We enrolled 38 patients who
treated with DES implantation. OCT and IVUS
measurements were performed in stented segments immediately
after percutaneous coronary intervention. We matched
OCT and IVUS images one by one, and analyzed TP
quantitatively in both measurements. Thirty patients
(78.9 %) were followed-up for 2 years to evaluate clinical
outcome of TP. TP was detected in 95 % of stented lesions
by OCT and 45 % of stented lesions by IVUS among 40
stented lesions in 38 patients. The best cut-off values of the
area, depth and burden of TP on OCT for the detection of
TP on IVUS were 0.17 mm2, 0.17 mm and 1.98 %,
respectively. There was no statistically significant relation
between TP and major adverse cardiac event during hospitalization
and 2-year follow-up.
