A 33-year-old man presented with respiratory distress and lower leg edema in April 2006. Atrial septal defect (ASD), complicated with moderate mitral regurgitation (MR), advanced tricuspid regurgitation (TR) and pulmonary hypertension (95/32mm Hg), was diagnosed. Qp/Qs was 6.3 and L-R shunt ratio was 84.4%. An "edge-to-edge" mitral valve plasty for MR complication as well as closure of the septal defect and tricuspid annuloplasty was performed, and a good result was obtained. It is known that ASD has a tendency to be accompanied by MR, and the strategy for treatment course for MR is debatable. The mitral lesions of MR complicating ASD are often seen in the posteromedial side of the anterior mitral leaflet, and usually many of the tendinous cords and valve leaflets are in the normal range in length. There have been reports on the mid-term results of edge-to-edge repair of mitral regurgitation due to degenerative lesions but the mid- and long-term results for MR complicating ASD, such as this case are unknown. We need to carefully observe the time course of this case.
