Abstract：Objective To summarize the surgical treatment experience of severe rheumatic mitral stenosis patients with small left ventricle( left ventricular end diastolic diameter≤40 mm) .Methods From April 2012 to Ju-ly 2013, 292 rheumatic heart disease patients including severe mitral stenosis patients with small left ventricle were performed open heart surgery by cardiopulmonary bypass.The clinical data of 3 severe mitral stenosis patients with small left ventricle were analyzed retrospectively.Results One patient died of multiple organ failure secondary to hy-poxemia, pulmonary infection, low cardiac output syndrome and acute renal failure.The other 2 patients were cured and discharged, and their cardiac function recovered to gradeⅠ~Ⅱ.During the following-up period with 13 to 18 months, left ventricular end diastolic diameters of 2 patients were 45 mm and 46 mm respectively, and left ventricular ejection fractions were 0.78 and 0.76 respectively.The two indexes were improved compared with preoperative inde-xes.Conclusion Severe rheumatic mitral stenosis patients with small left ventricle usually associate with long dura-tion, serious condition, tricuspid valve insufficiency and pulmonary arterial hypertension, even a part of patient de-velops into left ventricular atrophy and right heart insufficiency in advanced stage.Severe rheumatic mitral stenosis patients with small left ventricle have greater operation risk and higher mortality.
