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.
