The purpose of the study was to determine whether measures of right ventricular (RV) dysfunction on echocardiogram including RV strain were predictive of structural disease progression in ARVC.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Methods and Results<\/jats:title>\n            <jats:p xml:lang=\"en\">\n              A retrospective analysis of serial echocardiograms from 40 patients fulfilling 2010 task force criteria for ARVC was performed to assess structural progression defined by an increase in proximal RV outflow tract dimensions (parasternal short or long axis) or decrease in RV fractional area change. Echocardiograms were analyzed for RV free\u2010wall peak longitudinal systolic strain using 2\u2010dimensional speckle tracking. Risk of structural progression and 5\u2010year change in RV outflow tract measurements were compared with baseline RV strain. Of the 40 ARVC patients, 61% had structural progression with an increase in the mean parasternal short\u2010axis RV outflow tract dimension from 36.2 to 38.5\u00a0mm (\n              <jats:italic>P<\/jats:italic>\n              =0.022) and 68% by increase in parasternal long\u2010axis RV outflow tract dimension from 36.1 to 39.2\u00a0mm (\n              <jats:italic>P<\/jats:italic>\n              =0.001). RV fractional area change remained stable over time. Baseline RV strain was significantly associated with the risk of structural progression and 5\u2010year rate of change. Patients with an RV strain more positive than \u221220% had a higher risk (odds ratio: 18.4; 95% CI, 2.7\u2013125.8;\n              <jats:italic>P<\/jats:italic>\n              =0.003) of structural progression.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec xml:lang=\"en\">\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p xml:lang=\"en\">RV free wall strain is associated with the rate of structural progression in patients with ARVC.
