Left ventricular diastolic dimension was assessed via preoperative transthoracic echocardiography and left ventricular diastolic dimension index was calculated as left ventricular diastolic dimension\/body surface area. The primary outcome was a composite of death or readmission due to right heart failure or stroke. The cut-off left ventricular diastolic dimension index value most closely associated with outcomes was determined by receiver-operating characteristic curve and restricted cubic spline analyses.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Left ventricular diastolic dimension index measurements were available for 252 of 253 (99.6%) patients. Using a left ventricular diastolic dimension index cut-off value of 33.5\u2009mm\/m2, the cohort was divided: left ventricular diastolic dimension index \u2264 (n\u2009=\u2009131) or &amp;gt; (n\u2009=\u2009121) 33.5\u2009mm\/m2. While there were no significant differences in age, INTERMACS level and preoperative haemodynamics between groups, patients with smaller left ventricular diastolic dimension index were more likely to have a larger body surface area (2.1 vs 1.9\u2009m2, P\u2009&amp;lt;\u20090.001), ischaemic cardiomyopathy [64 (49%) vs 40 (33%), P\u2009=\u20090.01] and smaller left atrium volume index [40.5 (32.3\u201354.0) ml\/m2 vs 54.0 (43.0\u201366.8) ml\/m2, P\u2009&amp;lt;\u20090.001]. Smaller left ventricular diastolic dimension index patients had significantly worse survival (74% vs 88%, log-rank P\u2009=\u20090.009) and freedom from adverse events (55% vs 73%, log-rank P\u2009=\u20090.005) at 3-year follow-up. Smaller left ventricular diastolic dimension index was independently associated with the composite outcome (Hazard ratio 2.24, P\u2009=\u20090.002).<\/jats:p>\n               <\/jats:sec>\n
