Two dimensional Left Ventricular Volumes
Only three out of the six included studies reported standard
two-dimensional LV end-systolic and end-diastolic volumes, hence a
meta-analysis was not performed. All volumes were calculated using
Simpson’s Biplane method from the standard three apical views. Only one
study indexed two-dimensional volumes to body surface area(15). In this study, indexed
LV-EDV (ml/m2) was significantly higher in myocarditis
patients when compared to controls (59±13 vs 57±14, p=0.03). Overall,
there was no significant differences between non-indexed volumes in each
of the other individual studies.
