Abstract |
Left ventricular wall motion was observed with EKG
gated cardiac blood pool scan in 71 various cardiac
diseases and 10 normal controls to evaluate its
diagnostic and clinical significance in them. 1) In the
presence of left ventricular dysfunction, visual
evaluation of the left ventricular wall motion was
useful to determine whether it was due to localized or
diffuse abnormalities. In cardiomyopathy, marked left
ventricular dilatation and severe hypokinesia were
noted. 2) In myocardial infarction, regional wall
motion abnormalities well represented the location of
infarcted areas in majority of cases. Patients with
inferior wall infarction had smaller decrease of the
left ventricular ejection fraction and wall motion
grade than anterior or combined groups. In whom
persistent left ventricular failure was present, wall
motion analysis with gated cardiac scan provided
valuable information for the detection of ventricular
aneurysms. 3) Evaluation of the left ventricular wall
motion and its grading provided a reliable estimate of
the left ventricular function. In conclusion, visual
evaluation of left ventricular wall motion and its
grading provided valuable information for analyzing the
characteristics of regional and global left ventricular
dysfunction. |
