项目摘要
To assess the possibility that the mitral valve itself may be involved in
hypertrophic cardiomyopathy (HC), we studied mitral valves from 94
patients with HC and 45 in normal control subjects. The area of the
mitral leaflets were increased in patients with HC compared to controls
(12.9 -/+ 3.7 vs. 8.7 +/- 2.0 cm2; p < 0.0001). This increase was due
primarily to an increase in anterior leaflet length (2.2 +/- 0.5 for HC
vs. 1.8 +/- 0.3 cm for controls; p < 0.001), since circumference did not
differ between the 2 groups. Mitral leaflet area was increased (equal to
or less than 12.0 cm2) in 55 (58%) of the 94 valves. In 12 of these 55
valves both the anterior and posterior leaflets were enlarged; the other
43 valves had asymmetric or segmental enlargement of either the anterior
leaflet (36 patients) or the midportion of posterior leaflet (7
patients). Nine patients had a congenital malformation of the mitral
apparatus in which one or both papillary muscles inserted directly into
anterior mitral leaflet.
以评估二尖瓣本身可能参与的可能性
