Parameters of right ventricular size and systolic function
Only one published study was identified to have assessed parameters of
RV size and systolic function in patients with acute myocarditis
compared to controls and therefore none of the RV parameters of size and
systolic function were meta-analysed(17). This study by Caspar and
colleagues assessed standard measures of RV size and systolic function
in the apical four-chamber view with an average of the six segments
(including the RV free wall and septum). The right ventricular
parameters assessed included RVS’ (13.2±2 vs 14.2±2.1, p=0.028), RV
global strain (-20.6±3.5 vs -22.9±3.3, p=0.003) and RV free wall strain
(-24.6±5.4 vs -27.2±4.3, p=0.023), were all significantly lower in the
myocarditis population when compared to healthy controls.
