Is transmyocardial revascularisation of benefit in addition to coronary artery bypass grafting for patients with diffuse coronary disease?
A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether the use of transmyocardial revascularisation (TMR) in addition to coronary artery bypass grafting (CABG) is of benefit in patients with ischaemic heart disease with areas of ungraftable myocardium. Altogether 233 papers were found using the reported search, of which 9 represented the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results, and study weaknesses were tabulated. We conclude that while the society of thoracic surgeons now recommend TMR+CABG, and the available studies indicate that mortality is not increased by this additional procedure, it is currently not clear whether TMR reduces symptoms of angina in addition to CABG alone.
