Background-The SYNTAX score (SXscore) has been proposed recently as a valuable tool to characterize the coronary vasculature prospectively with respect to the number of lesions and their functional impact, location, and complexity. However, the prognostic value of SXscores in patients undergoing percutaneous coronary intervention of the left main artery has not been validated. Methods and Results-We applied the SXscore in 255 consecutive patients who underwent percutaneous coronary intervention for left main disease and explored its performance with respect to their clinical outcome. Univariate and multivariate Cox proportional hazard regression analyses were performed to evaluate the relation between the SXscore and the incidence of cardiac mortality, the primary end point of the study, and major adverse cardiac events (MACE
A SYNTAX score threshold of 34 may usefully identify a cohort of patients with left main disease who benefit most from surgical revascularization in terms of mortality.
TAVI with the currently adopted CoreValve generation was associated with sustained clinical outcomes up to 5-year follow-up, with a low rate (1.4%) of significant prosthetic valve degeneration. The procedure appears to be an adequate and lasting resolution of aortic stenosis in selected high-risk patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
