CORONARY ARTERY DISEASE IN SINGLE VALVE REPLACEMENT VERSUS DOUBLE VALVE REPLACEMENT: A LITERATURE REVIEW

Abstract

The prevalence of CAD in patients requiring valvular surgery is 20-40%. Clinicallythe patient is advised to receive surgery when the level of stenosis exceeds 50%.The aim of our study was to provide a complete picture of the prevalence andincidence of CAD in valvular surgery patients along with examining the mortalityrates and causes of CAD within the same group of patients. A wide rangedliterature search was conducted using PubMed, to find all the various publishedoriginal articles comparing morbidity and mortality rates, along with theprevalence of CAD in valve surgery patients, as late as May 2015.Consequently,3957 articles were found and then reviewed as part of theexclusion criteria, after which 10 studies were incorporated in our study. Out ofwhich, 5 were based on incidence of CAD among AVR patients, 2 focused onCAD with MVR and remaining 3 indicated overall picture of CAD in DVR ( dualvalve replacement) patients.
