Evaluation of the competence of a mitral valve can often be impossible in the clinical setting of a giant atrial myxoma. A 50-year-old woman with severe mitral regurgitation in the post-bypass period following a myxoma resection was managed with a mitral valve replacement. The absence of mitral insufficiency in the preoperative examination should not be taken as a reliable predictor of normal valve function. So herein, we discuss the role of the intraoperative echocardiographic examination, the underlying mechanisms, and the proposed management of severe mitral regurgitation following the resection of an atrial myxoma.
