BACKGROUND: International guidelines recommend a preoperative coronary angiography prior valve replacement. Coronary computed tomography angiography (CCTA) is a non-invasive study which has emerged as an alternative option. However, at the present time is not thae preferred imaging test for this purpose. OBJECTIVE: The objective of the study is to evaluate the prognostic value of CCTA to predict death and / or myocardial infarction in the post-surgical period of valve replacement.METHODS: This is a cohort study which included patients with valvular heart disease and low-intermediate pre-test probability of coronary artery disease (CAD), who underwent CCTA as part of their preoperative assessment, and who had not been previously diagnosed with CAD. Primary outcome included death and/or perioperative myocardial infarction.RESULTS: A total of 319 patients were included, predominantly female, with an average age of 559.7 years. Only 4.7% presented obstructive CAD. The independent predictors of death and/or myocardial infarction were non-CAD in CCTA and high-risk EuroSCORE.CONCLUSION: In low-intermediate pre-test probability of CAD, CCTA represents an important prognostic value to predict death and/or myocardial infarction in the postoperative period of valvular surgery, so it could be used as an initial screening method in this group of patients.
