Echocardiography was performed within two days before PVI<\/jats:styled-content>. Maximum (Max\u2010LAV<\/jats:styled-content>i) and minimum LA<\/jats:styled-content> volume index (Min\u2010LAV<\/jats:styled-content>i) were calculated with the biplane modified Simpson's method, and then normalized to the body surface area. On the basis of previous findings, the predefined cutoff value of Max\u2010LAV<\/jats:styled-content>i for AF<\/jats:styled-content> recurrence was set at Max\u2010LAV<\/jats:styled-content>i\u00a0\u2265\u00a034\u00a0mL\/m2<\/jats:sup>. \u0394LA<\/jats:styled-content> volume index (\u0394LAV<\/jats:styled-content>i) was also calculated as Max\u2010LAV<\/jats:styled-content>i minus Min\u2010LAV<\/jats:styled-content>i. The follow\u2010up period after PVI<\/jats:styled-content> was 24\u00a0months.<\/jats:p><\/jats:sec>Results<\/jats:title>AF<\/jats:styled-content> recurrence was observed in 35 patients. Multivariate logistic regression analysis showed that \u0394LAV<\/jats:styled-content>i (odds ratio [OR<\/jats:styled-content>]: 1.131; 95% confidence interval [CI<\/jats:styled-content>]: 1.057\u20101.221; P<\/jats:italic>\u00a0<\u00a00.001) was an independent predictor of AF<\/jats:styled-content> recurrence. Sequential logistic regression models for predicting AF<\/jats:styled-content> recurrence revealed that a model based on clinical variables including age, gender and AF<\/jats:styled-content> duration (\u03c7<\/jats:italic>2<\/jats:sup>\u00a0=\u00a01.65) was improved by the addition of Max\u2010LAV<\/jats:styled-content>i\u00a0\u2265\u00a034\u00a0mL\/m2<\/jats:sup> (\u03c7<\/jats:italic>2<\/jats:sup>\u00a0=\u00a013.8; P<\/jats:italic>\u00a0<\u00a00.001), and further improved by the addition of \u0394LAV<\/jats:styled-content>i (\u03c7<\/jats:italic>2<\/jats:sup>\u00a0=\u00a018.2; P<\/jats:italic>\u00a0=\u00a00.036). Of note is that only 1.02\u00a0\u00b1\u00a00.10\u00a0minutes per patient was needed to obtain a comprehensive LA<\/jats:styled-content> assessment that included Max\u2010LAV<\/jats:styled-content>i,
