Abstract

Left atrial dissection does occur, though rarely, after mitral valve surgery. A 68-year-old Korean female presented with moderate mitral stenosis, mild mitral regurgitation, moderate tricuspid regurgitation and mild aortic regurgitation. She was scheduled for mitral valve replacement and tricuspid annuloplasty. We experienced a left atrial dissection after weaning from cardiopulmonary bypass and decided not to repair it. The patient recovered uneventfully. We suggest that a specific type of left atrial dissection can be treated conservatively.
