Pak Heart J Jan ;51(1):5-8.

The prevalence of CAD in patients requiring valvular surgery is 20-40%. Clinically the 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 and incidence of CAD in valvular surgery patients along with examining the mortality rates and causes of CAD within the same group of patients. A wide ranged literature search was conducted using PubMed, to find all the various published original articles comparing morbidity and mortality rates, along with the prevalence of CAD in valve surgery patients, as late as May 2015.Consequently,3957 articles were found and then reviewed as part of the exclusion criteria, after which 10 studies were incorporated in our study. Out of which, 5 were based on incidence of CAD among AVR patients, 2 focused on CAD with MVR and remaining 3 indicated overall picture of CAD in DVR ( dual valve replacement) patients.
