We report a case of a 28-year-old woman with severe mitral stenosis fo
r which surgical closed commissurotomy was done. Intraoperative transe
sophageal echocardiography was performed to assess its utility during
this surgical procedure. It was helpful in instant confirmation of the
adequacy of the surgery, detecting residual mitral regurgitation, and
in visualisation of the Tubbs dilator that is used to accomplish mitr
al commissurotomy.
