RUPTURE OF MITRAL-VALVE ANNULUS AFTER MITRAL BALLOON VALVOTOMY - A CASE-REPORT

We report the case of a 51-year-old woman who underwent percutaneous m itral valvotomy using single balloon technique for restenosis after a previous surgical closed commissurotomy. After the procedure, she pres ented with severe mitral regurgitation and was referred to our center for mitral valve replacement. At surgery, the underlying cause of the mitral regurgitation was shown to be a tear at the commissural site wh ich extended into the annulus. The mitral valve was successfully repla ced and the postoperative course was uneventful. One year later the pa tient is in good clinical condition.
