PO-05-061 RIGHT VENTRICULAR SYSTOLIC FUNCTION ON MRI IS RELATED TO APPROPRIATE ICD THERAPY

Right ventricular function is recently referred as an independent predictor of sudden cardiac death (SCD). The purpose this study was to evaluate the association right ejection fraction (RVEF) on magnetic resonance imaging (MRI) and appropriate ICD therapy. Consecutive patients who underwent initial implantation for any diseases except non-dilated phase hypertrophic cardiomyopathy channelopathy were retrospectively enrolled from 2012 2018 followed up therapy death. We MRI before implantation. RVEF, RV radial strain, circumferential strain (RVCS), 4 chamber transmural longitudinal stain evaluated investigate with RVEF analyzed software (MR Multi-Chamber Wall Motion Tracking, Canon). In total, 97 (58.5±14.5 years, 69 males) including 20 ischemic enrolled. Fifty-one received a secondary prophylaxis. Mean LVEF 37.4±14.5% 36.2±12.6%, respectively. There no correlation between (correlation coefficient =0.36). Regarding events, best cut-off value 43.0%. hazard ratio (HR) low 9.601 (95%CI: 1.287-71.6, P=0.027). Secondary prophylactic cohort showed highest incidence shown in figure. multivariate analysis about RVCS predictors (RVEF:HR 12.4, 95%CI:1.51-101, P=0.019 strain: HR 0.8, 95%CI:0.76-0.98, P=0.021). group (-11.1±4.6%) lower than non-therapy (-7.0±11.7%). Low predicted higher associated increased
