Follow-up LAD (A), LVEDD (B), LVEDV (C), LVEF (D) results of patients who had mitral valve re-repair only (n = 10). Follow-up results of patients with no more than moderate MR grade (E) and patients with mild MS grade (F) who had mitral valve re-repair only (n = 10). Patients included in the analysis should have a follow-up period of at least 1 year. Significant decrease was discovered at postoperative 24 h compared with preoperative (P = 0.044). Compared to the preoperative number of patients with moderate or less MR, there was a significant increase at postoperative 24 h (P = 0.008) and at 3 months (P = 0.031). LAD, left atrium diameter; LVEDD, left ventricular end-diastolic diameter; LVEDV, left ventricular end-diastolic volume; LVEF, left ventricular ejection fraction; MR, mitral valve regurgitation; MS, mitral valve stenosis
