| 摘 要： | 通过MRI诊断肥厚型心肌病(HCM)9例。结果:9例左心室腔变形,以狭长形多见,舒张不良5例,收缩不良1例。左室游离壁肥厚部位收缩增厚比7例<1.25,左室流出道狭窄2例,室中隔中部肥厚3例,局部球形增厚1例,一致性肥厚4例,心尖肥厚1例。其收缩增厚比4例为1.0,提示室间隔几乎无运动。5例左房增大。6例室中隔信号强度不均匀,其中3例与心肌组织学对比提示了心肌组织变性程度。4例冠状动脉近端清晰可见,无狭窄。

| Abstract: | Niene patients with ECM are confirmed ty MRI, Results show: all ofthem with the left ventricular deformation, most of deformation are narrowand long type; 7 with decreased diastolic function, 1 with cecreased contractivefunction. In 7 patients the ratio of thickness during systole to that of diastoleis less than 1.25 in hypertrophic region of left ventricular free wall; 2 withleft ventricular cutflow narrowness. Among 9 patients 3 with septal hypertr-ophy in the middle part, 1 with ball-like hypertrophy in local area of septum.Four with hyportrophy of whole interventricular septum. In 4 patients theratio of the thickness during systole to that of diastoie is 1.0, this ratiosuggests no motion of hypertrophic interventricular septum. Five with leftatrial enlargement, 6 whth different signal intensity in septum, in throe ofthem signal indicates the degenerated degree of myocardial tissue. In 4 patientsthe proximal ends coronary arteries show no narrowness. |
