Pak J Cardiol Jan ;18(1-2):18-24.

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.
