Systematic Review and Meta-analysis of Prevalence of Coronary Artery Disease in Adult Patients with Cardiac Myxomas

Background : Studies have reported varied prevalence estimates of coronary artery disease (CAD) in cardiac myxoma patients. We performed a systematic review and meta-analysis of observational studies to summarize the point prevalence of CAD in adults with cardiac myxomas. Methods and Results : Two independent investigators searched MEDLINE and LILACS databases using the terms " Myxoma ”, " Coronary Angiography " and " Coronary Disease " from inception through December 2014 for all relevant studies. We included 6 observational studies. Publication bias was evaluated through Egger's test and Trim and Fill method. A pooled estimate of CAD prevalence with corresponding 95% confidence interval (CI) was calculated based on a random-effects model. The pooled CAD prevalence in adult cardiac myxoma patients was 20.7% with low heterogeneity (I 2 = 14.86%). Conclusions : It is a matter of debate if preoperative coronary angiography must be done as a routine procedure. Although coronary disease and angiographically detectable neovascularity can alter surgical management, more studies are needed to evaluate this question.
