ABSTRACT
@#Objective    To analyze factors affecting the recovery of postoperative left ventricular function in patients with valvular disease combined with heart failure with reduced ejection fraction [HFrEF, left ventricular ejection fraction (LVEF)<40%]. Methods    The clinical data of 98 patients with valvular disease combined with HFrEF who underwent surgeries in our hospital from January 2011 to June 2018 were retrospectively analyzed, including 75 males and 23 females aged 9-78 (55.3±11.9) years. Results    A total of 15 patients were dead after the operation, including 4 deaths within 3 months and 11 mid-long-term deaths after the operation. Ninety-one patients were followed up for more than 6 months (10 months to 8.6 years). The postoperative cardiac function (NYHA) of 91 patients was classⅠ-Ⅱ, the LVEF of 18 (19.8%) patients increased more than 10%, that of 47 (51.6%) patients maintained at the preoperative level, and that of 26 (28.6%) patients decreased. Postoperative LVEF was more prone to recover in HFrEF patients with sinus rhythm before operation (P=0.038), valvular disease mainly in aortic valve (P=0.026), obvious reduction of left ventricular end diastolic diameter in early postoperative period (P=0.017), and higher systolic pulmonary artery pressure (SPAP) before operation (P=0.018). The risk factors for postoperative LVEF deterioration included large left atrium before operation (P=0.014), smaller left ventricle end systolic diameter before operation (P=0.003), and fast heart rate after operation (P=0.019). Conclusion    Mitral valve prolapse patients with obviously increased left ventricular diameter should receive operation as soon as possible. HFrEF patients with aortic valve disease should receive operation positively. The operation efficacy is satisfactory in the HFrEF patients with high SPAP.
