Giant left atrium is a rare condition, with a reported incidence of 0.3%, that is normally caused by rheumatic mitral valve disease but very rarely is caused by other etiologies. In such patients, annular dilatation with tenting and reduced height of the posterior leaflet result in significant mitral regurgitation. At surgery, the posterior leaflet was incised from the posterior mitral annulus, starting the incision at the mid portion of the mitral annulus

and, if necessary, extending it to the anterolateral portion of the mitral annulus and the posteromedial portion of the mitral annulus. An autologous pericardial patch was harvested, depending on the incision. Herein is reported a surgical technique for posterior leaflet extension in patients with giant left atrium, without rheumatic disease.
