Background: Recurrent revascularization is frequently
needed in despite to the modern treatment options of coronary artery
disease. Recurrent revascularization has
need special caution in the setting of previous coronary bypass surgery (CABG). There is no study to
investigate possible adverse effects of prior
CABG on percutaneous coronary interventions (PCI). This study investigated that PCI results of the patients
with prior CABG.
Methods: Patients who underwent
PCI screened retrospectively. Consecutive 100 patients had been prior PCI (group 1), and 100 patients had been prior
CABG (group 2) were enrolled to the study. The patients were not enrolled in the study;
index PCI underwent bypass graft or total occluded lesion or instant lesion or in the setting of ST
elevation myocardial infarction or bifurcation stenting was done.
Results:
Group 1 and group 2 were similar in terms of age and
gender. No statistically significant difference was observed between other
demographic features. The lesion severity was not significantly different
between the groups. In the CABG group, the intervention was more frequent to
the Cx lesion; while in the PCI group, intervention to the LAD lesion was more
frequent. Factors that made the procedure difficult were similar in both groups. There was no significant difference
between the two groups regarding lesions longer than 20 mm and diffuse coronary
artery disease. Balloon and stenting were more frequent in the CABG group, and
direct stenting was more frequent in the PCI group (p<0.05) Balloon dilatation was found to be
more frequent in the CABG group. The duration of the procedure, number of
angiographic frames and films, amount of contrast material used were
significantly higher in the CABG group, as the difference between the two
groups was not significant regarding balloon pressures applied during stenting. Previous CABG history was found to be
an independent variable for the duration of the procedure and the number of
angiographic frames. Prior
CABG also has a significant correlation
with prolonged intervention duration, radiopaque volume, and cine-angiography film and frame counts when
controlling for intervened artery and prior
index intervention time interval.
