The following parameters were prospectively assessed before and after T-TEER: left ventricular (LV) diastolic properties by invasive pressure\u2013volume loop recordings; biventricular time\u2013volume curves and function as well as septal curvature by cardiac magnetic resonance imaging; strain analyses for timing of septal motion. Overall, 20 patients (median age 78, interquartile range [IQR] 72\u201383\u2009years, 65% female) were included. T-TEER reduced TR by a median of 2 (of 5) grades (IQR 2\u20131). T-TEER increased LV stroke volume and LV end-diastolic volume (LVEDV) (p\u2009&amp;lt;\u20090.001), without increasing LV end-diastolic pressure (LVEDP) (p\u2009=\u20090.094), consequently diastolic function improved with a reduction in LVEDP\/LVEDV (p\u2009=\u20090.001) and a rightward shift of the end-diastolic pressure\u2013volume relationship. The increase in LVEDV correlated with a decrease in RV end-diastolic volume (p\u2009&amp;lt;\u20090.001) and LV transmural pressure increased (p\u2009=\u20090.028). Secondary to a decrease in early RV filling, improvements in early LV filling were observed, correlating with an alleviation of leftwards bowing of the septum (p\u2009&amp;lt;\u20090.01, respectively).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Diastolic LV properties in patients with HFpEF and severe TR are importantly determined by ventricular interaction in the setting of RV volume overload.
