Peak LV and LA LS and AV coupling, assessed by combined peak LA and LV strain, was compared between the groups. Analysis of variance and two-sided t-tests were used, and a P-value of &amp;lt;0.01 was considered significant. LV strain was significantly lower in those with MMAVD compared with controls and those with moderate or severe isolated AR but comparable to those with moderate or severe AS (\u221217.1 \u00b1 1.1% MMAVD vs. \u221217.7 \u00b1 1.5% moderate AS, P = 0.02, vs. \u221217.0 \u00b1 1.5% severe AS, P = 0.74). AV coupling was significantly lower in those with MMAVD compared with controls and those with moderate AS or AR but comparable to those with severe AS or AR (47.1 \u00b1 6.8% MMAVD vs. 45.1 \u00b1 5.6% severe AS, P = 0.13, vs. 50.4 \u00b1 9% severe AR, P = 0.07).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Impairments in AV coupling are comparable for patients with MMAVD and those with severe isolated AS or AR.
