This study aimed to investigate the association between RV damage detected by RV free wall longitudinal strain (RVFWLS) and outcomes in patients with severe aortic stenosis who underwent transcatheter aortic valve implantation (TAVI).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p xml:lang=\"en\">A total of 768 patients with severe aortic stenosis who underwent TAVI and echocardiographic images for RV functional assessment were included from a retrospective multicenter TAVI registry. The primary outcome was a composite of all\u2010cause death and hospitalization due to cardiovascular events.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">During a median follow\u2010up of 21 (12\u201330) months, 213 patients (28%) experienced the primary end points. In the multivariable Cox proportional hazards model, a higher absolute RVFWLS value was independently associated with better outcomes (adjusted hazard ratio [HR], 0.88 [95% CI, 0.84\u20130.91]). RVFWLS demonstrated incremental values superior to those of conventional RV parameters. Adding RVFWLS &lt;17% as an RV damage (Stage 4) criterion in staging classification identified 272 (35%) patients in Stage 4. Patients with RVFWLS\u2010incorporated Stage 4 had lower event\u2010free survival than did those in the other stages (adjusted HR, 1.55 [95% CI, 1.35\u20131.77]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p xml:lang=\"en\">In patients with severe aortic stenosis who underwent TAVI, RVFWLS was independently associated with outcomes and provided superior prognostic value than other conventional RV echocardiographic parameters. Incorporating RVFWLS in a staging classification for RV damage showed incremental value for predicting survival after TAVI over the original staging classification.<\/jats:p>\n
