Echocardiographic profile of patients with mitral stenosis

ABSTRACT

Rheumatic heart disease is a common cardiovascular disease in our country. These patients are referred to echocardiography laboratory for the evaluation of valvular lesions. In this study we are presenting the echo-cardiographic data of patients with mitral stenosis referred to our lab during 2006. We have retrospectively analyzed the data of patients with mitral stenosis [MS]. A total of 3393 echo studies were performed during this year. Out of these 70 patients had significant MS. Of these 42[60%] were female and 28[40%] were male patients. The mean age of these patients was 41.13 +/- 12.64 years [Range 17-70 years] and the median age of 40 years. The mean age of patients with mild MS was 48.63 +/- 12.38 years, with moderate MS was 40.33 +/- 12.52 and with severe MS was 34.67 +/- 9.12 years. All patients had dilated left atrium and normal sized left ventricle. The mean diameter of left atrium was 45.65mm. The mean of MVA by planimetry was 1.28 +/- 0.39 cm2 and by pressure half time method was 1.25 +/- 0.35 cm2 [P=0.366]. The mean MVA in female patients was 1.33 +/- 0.31cm2 and 1.21 +/- 0.49 cm2 and in male patients was 1.21 _0.31 cm2 and 1.28 +/- 0.39 cm2 by planimetry and PHT methods respectively. The mean of mean pulmonary artery pressure was 49.26 +/- 26.82 mmHg. In female patients it was 44.49 +/- 22.33 mmHg and in male patients 57.35 +/- 32.0 mmHg [P=0.024]. 19[27.1%] patients had mild MS, 33[47.1%] moderate and severe in 18[25.1%] patients. Mitral regurgitation was present in 36[51.4%] patients, tricuspid regurgitation in 33[49.1%] patients and 13[18.6%] patients had calcification on leaflets or commissures
