Echocardiographic left ventricular ejection fraction was assessed, and a 16-segment model was adopted for regional analysis of the left ventricle. A total of 1616 segments were analysed based on a 6-point scale: 1\u2009=\u2009normal (N\u2009=\u20091083), 2\u2009=\u2009mild hypokinesia (N\u2009=\u20092), 3\u2009=\u2009moderate hypokinesia (N\u2009=\u200974), 4\u2009=\u2009severe hypokinesia (N\u2009=\u2009150), 5\u2009=\u2009akinesia without thinning (N\u2009=\u2009259) and 6\u2009=\u2009akinesia with thinning (N\u2009=\u200948).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>The serial left ventricular ejection fraction measured preoperatively, before discharge, at postoperative 3- and 12-months were 0.48\u2009\u00b1\u20090.14, 0.49\u2009\u00b1\u20090.12, 0.49\u2009\u00b1\u20090.10 and 0.54\u2009\u00b1\u20090.10, respectively. The left ventricular ejection fraction significantly increased over time during the postoperative 12\u2009months (P\u2009&amp;lt;\u20090.001). Wall motion scores tended to decrease over time in both segment groups with akinesia and without akinesia (P\u2009&amp;lt;\u20090.001), and improvement of the wall motion was significantly higher in the segment group with akinesia than in the segment group without akinesia (P\u2009&amp;lt;\u20090.001).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>The left ventricular ejection fraction and regional wall motion improved over time during the postoperative 12\u2009months, regardless of the presence of an akinetic segment.
