In addition, the impact of afterload and the involved mechanisms are unclear. In this work, we study the relationship between LV function assessed with myocardial work index (MWI) and arterial stiffness in a cohort of normal functioning BAV patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this study, we included a total of 38 consecutive patients with isolated BAV and 44 age\u2010 and gender\u2010matched control subjects with tricuspid aortic valve. All participants underwent transthoracic echocardiography to assess conventional parameters and global longitudinal strain (GLS). In addition, MWI was measured by the noninvasive LV pressure\u2010strain cycle method. Aortic pulse wave velocity (PWV) and wave reflection were evaluated by applanation tonometry.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean aortic PWV was significantly higher in BAV patients (6.4\u2009\u00b1\u20090.80, 7.02\u2009\u00b1\u20090.1.2, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.01, respectively). LV\u2010MWI related parameters such as global work efficiency (GWE) (96.261.69 and 97.051.27, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.02) and global wasted work (GWW) (78.232.1 and 61.824.4, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.01) were found significantly different between the BAV and control groups. However, global working index and global constructive working were not different between groups (1969\u2009\u00b1\u2009259 and 2014\u2009\u00b1\u2009278, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.45; 2299\u2009\u00b1\u2009290 and 2359\u2009\u00b1\u2009345, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.39, respectively).
