Two groups were identified based on left atrial size: group 1\u2009&lt;\u200960\u2009mm ( n\u2009=\u200979) and group 2\u2009&gt;\u200960\u2009mm ( n\u2009=\u200937).

This correlated with preoperative mitral valve area ( p\u2009=\u20090.009), preoperative mitral regurgitation ( p\u2009=\u20090.000), and preoperative atrial fibrillation ( p\u2009=\u20090.022). Linear regression analysis revealed atrial fibrillation ( p\u2009=\u20090.001, b1\u2009=\u20096.006), a high grade of mitral regurgitation ( p\u2009=\u20090.001, b1\u2009=\u2009\u22123.812), and larger size of the left atrium ( p\u2009=\u20090.000, b1\u2009=\u2009\u22120.701) predicted a greater reduction of left atrial size during follow-up. Left atrial size decreased by 28\u2009mm in patients with a preoperative left atrium &gt;60\u2009mm (75% sensitivity and 100% specificity).<\/jats:p>\n                  <\/jats:sec>\n
