Comparative StudySeverity of tricuspid regurgitation is associated with long-term mortality.
To determine the association between intraoperative/presurgical grade of tricuspid regurgitation (TR) and mortality, and to determine whether surgical correction of TR correlated with an increased chance of survival compared with patients with uncorrected TR. ⋯ Our study of more than 20,000 patients demonstrates that grade of TR is associated with increased risk of mortality after cardiac surgery. In addition, all patients who underwent TV surgery had a statistically significantly increased likelihood of survival compared with those with the same degree of TR who did not undergo TV surgery.

Observational StudySerum glial cell line-derived neurotrophic factor levels and postoperative cognitive dysfunction after surgery for rheumatic heart disease.
Postoperative cognitive dysfunction is an important complication of cardiac surgery with poor outcomes. Serum glial cell line-derived neurotrophic factor levels are decreased in patients with Alzheimer's disease, but the association between glial cell line-derived neurotrophic factor levels and postoperative cognitive dysfunction is poorly understood. The present study aimed to investigate the prognostic value of postoperative serum glial cell line-derived neurotrophic factor levels to predict postoperative cognitive dysfunction in patients with rheumatic heart disease undergoing heart valve replacement. ⋯ The perioperative glial cell line-derived neurotrophic factor levels in patients with postoperative cognitive dysfunction were lower than in patients without postoperative cognitive dysfunction. Glial cell line-derived neurotrophic factor could be an effective predictor for the occurrence of postoperative cognitive dysfunction. The results reveal a potentially important role of decreased glial cell line-derived neurotrophic factor levels in postoperative cognitive dysfunction, with possible treatment targets.
