Figure 1 Schematic of the RV Wall Segments and Scoring
The right ventricle (RV) was analyzed using a 3-segment model and 5-point scale for wall motion. Top right is the "bull’s eye" incorporating the 17-segment model for the left ventricle and the 3-segment model for the RV. APx = apex.

Figure 2 Event-Free Survival as a Function of RV Stress Wall Motion Abnormalities
The number of patients at risk for each follow-up period is given below the graph. Patients with abnormal right ventricle (RV) have a 7-fold higher event rate compared with those with a normal RV.

Figure 3 Event-Free Survival as a Function of LV and RV Stress Echocardiography Results
The number of patients at risk for each follow-up period is given below the graph. Right ventricular (RV) wall motion analysis during stress further risk-stratified the results of stress echocardiography based on the left ventricle (LV). Patients with abnormal RV and LV both had a worse prognosis. Abn = abnormal.
