Mitral valve surgery--a Scandinavian perspective.

During the last three decades, the most prevalent surgical mitral valve disease in Scandinavia has changed from the sequelae of rheumatic fever to the mitral valve pathologies related to ischemic heart disease. Also, the total number of patients in need of a mitral valve procedure is increasing. For several of the patients with ischemic mitral valve disease, the natural prognosis of their disease is dismal. However, there are several uncertainties as to whether or not a surgical procedure can improve the life expectancies of these patients. Also, the procedures of choice for patients with ischemia related "functional mitral valve disease" is a long standing controversy. In this issue of "Scandinavian Cardiovascular Journal" we present the rationale and protocol for the "MoMIC" trial, a randomized multicenter study aiming to clarify whether revascularization alone or a combined revascularization and mitral valve annuloplasty is the treatment of choice for patients with ischemia related moderate mitral regurgitation.
