Mitral stenosis: Mitral dome excursion at M1 and the mitral opening snap—The concept of reciprocal heart sounds
American Heart Journal(1988)
摘要
The dynamics of the delayed accentuated mitral component (M1) of the first heart sound and the MOS were studied in 11 patients with mitral stenosis of varying severity. Echophonocardiographic (M-mode and 2D) studies were performed with analysis of LA dimensions, dynamics, and mitral valve excursion at the time of M1 and MOS. LA area and length, mitral annular diameter, and mitral dome area (from anulus plane to fused valve tip) and length were measured at M1 and MOS.
