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.
