CABG Versus Myotomy in Symptomatic Myocardial Bridge Patients : A Systematic Review and Meta-analysis Protocol

Review question / Objective: The aim of this study is to find which surgical intervention in myocardial bridge ( myotomy or CABG) is more effective in reducing adverse outcomes in symptomatic patients resistant to optimal medical therapy ? Condition being studied: Myocardial bridge : A myocardial bridge (MB) is a congenital heart defect in which a bridge of muscle fibers (myocardium) overlying a section of a coronary artery and the artery is squeezed and normal blood flow is disrupted. Most bridges don't seem to cause symptoms. However, some people can experience angina, or chest pain. In patients with symptoms, first line treatment is medication and if they have symptoms despite optimal medical treatment , invasive measures like CABG or myotomy should be taken.
