- 論文の詳細を見る
Re-evaluation of Q-1 and 2-OS intervals and (Q-1)-(2-OS) index was attempted on preoperative phonocardiogram in mitral stenosis. Fibrosis of mitral value relates to Q-1 interval and this disturbs the correlation between Q-1 interval and the size of mitral orifice and left atrial pressure. 2-OS interval showed good correlation to the size of mitral orifice and left atrial pressure. The effect of fibrosis of mitral valve on this interval seems little. (Q-1)-(2-OS) index showed rough correlation to the size of mitral orifice but less correlation to left atrial pressure, probably due to fibrosis of mitral valve. Postoperative phonocardiograms reveal the clinical course of patient postoperatively and preoperative value of Q-1 and 2-OS intervals return toward normal value unless congestive failure or incomplete commissurotomy present.
