Left atrial reduction and mitral valve replacement in a 5-year-old girl with severe mitral regurgitation and giant left atrium.

Giant left atrium associated with mitral valve disease has been implicated in the morbidity following mitral valve repair or replacement. Various methods including left atrial plication have been described to reduce the size of left atrium. Herein we describe our technique of left atrial reduction in a 5-year-old girl with severe mitral regurgitation and giant left atrium. She underwent mitral valve replacement and circumferential left atrial reduction with successful outcome.
