ObjectiveSystemic immune-inflammation index (SII) is a novel biomarker that can predict poor outcomes in tumours, nervous system diseases and chronic heart failure. Here, we investigated the predictive value of SII on the poor postoperative outcomes and short-term prognosis of heart valve diseases (HVDs).Design, setting and participantsThis retrospective cohort study enrolled all consecutive patients with HVDs (aortic stenosis, aortic regurgitation, mitral stenosis and mitral regurgitation) who underwent surgery (valve replacement or valve repair) at the Affiliated Hospital of North Sichuan Medical College between 2017 and 2020.Main outcomes and measuresMajor complications in the perioperative period, all-cause mortality within 30 days and readmission within 30 days.ResultsA total of 431 patients with HVDs were enrolled in this study, including 202 males and 229 females, aged 58.9±27.3 years. SII levels of patients in the poor outcomes group were significantly higher than those of patients in the favourable outcomes group (658.40±436.29 vs 335.72±174.76, respectively; p9 /L, with a sensitivity of 70.3% and specificity of 81.1%. The incidence of poor outcomes (pConclusionsSII is closely related to poor postoperative outcomes and short-term prognosis of HVD and can serve as an independent predictive factor.

Total anomalous pulmonary venous drainage (TAPVD) is caused by the absence of the congenital connection between the pulmonary vein and left atrium. This causes blood drainage into the right atrium, resulting in poor development of the left atrium and increasing the burden for the right atrium. It is accompanied by an atrial septal defect. TAPVD mostly is diagnosed during the fetal period and rarely is reported in adults. Atrial fibrillation (AF), a common arrhythmia, originates primarily from the joint of the pulmonary vein and left atrium, whereas AF originating from the right atrium has not been documented. Herein, we report the case of a 45-year-old male diagnosed with TAPVD accompanied by AF. After the correction of TAPVD and radiofrequency ablation (RFA) for AF performed under general anesthesia and cardiopulmonary bypass, the patient returned to normal sinus rhythm and showed no AF recurrence during two years of follow up.
