Abstract
Abstract Objectives: There are several different definitions of complete
revascularization on coronary surgery across the literature. Despite the
importance of this definition there is no agreement on which one has the
most impact. The aim of this study was to evaluate which definition of
complete surgical revascularization correlates with early and late
outcomes. Methods: All consecutive patients submitted to isolated CABG
from 2012 to 2016 with previous myocardial scintigraphy were evaluated.
Exclusion criteria: emergent procedures and previous cardiac surgery
procedures. Population of 162 patients, follow-up complete in 100%
patients; median 5,5 IQR 4,4-6,9 years. Each and all of the 162 patients
were classified as complying or not with the four different definitions:
Numerical, Functional, Anatomical Conditional and Anatomical
unconditional. Univariable and multivariable analyses were developed to
detect if any definition was a predictor of perioperative and long-term
outcomes. Results: Complete functional revascularization was a predictor
of increased survival (HR 0.47 CI95: 0,226-0,969; p=0.041). No other
definitions showed effect on follow-up mortality. Age and cardiac
dysfunction increased long-term mortality. The definition of complete
revascularization did not have an impact on MACCE or need for
revascularization Conclusions: An uniformly accepted definition of
complete coronary revascularization is lacking. This research raises
awareness about the importance of viability guidance for CABG.
