All measurements are represented as mean (standard error)
CSAd=cross-sectional area of LV in diastole (in mm2)
CSAs=cross-sectional area of LV in systole (in mm2)
FAC=fractional area change of LV (%)
Base = baseline pre-surgery value
4w = 4 weeks after surgery
Δ = change from baseline to 4 weeks after surgery (4w – base)
*
p<0.01 for the comparison of C with the RV and BIV groups
†
p<0.05 for the comparison of BIV versus RV group
