  • Description: We determined the left ventricular end-systolic diameter (LVDs) cut-off value for risk of major adverse cardiac and cerebrovascular events (MACCE) in Japanese asymptomatic or mildly symptomatic patients undergoing aortic valve replacement (AVR) for aortic valve regurgitation (AR), and investigated the effect of left ventricular dilation on long-term postoperative outcomes.Methods and Results: The 168 patients who underwent surgical AVR for AR at Shiga University of Medical Science between January 2002 and December 2022 were included in this study. Receiver operating characteristic curve analysis showed that the cut-off value of preoperative LVDs for the incidence of MACCE was 42.8 mm (area under the curve 0.616). Postoperative outcomes were compared between patients with preoperative LVDs >42.8 mm (n=77) and those with preoperative LVDs ≤42.8 mm (n=91) using propensity score matching. The 10-year estimated rates of freedom from MACCE in those with LVDs >42.8 and ≤42.8 mm were 59.9% and 85.7%, respectively; the curves differed significantly (P=0.004). In multivariable Cox proportional hazard regression analyses, preoperative LVDs >42.8 mm was an independent predictor of MACCE (hazard ratio 2.485; 95% confidence interval 1.239-4.984; P=0.010). Preoperative LVDs >42.8 mm is associated with an increased risk of MACCE in Japanese patients undergoing AVR for AR.
