A Diuretic Response is Associated with the Early Prognosis of Patients Undergoing Repeat Tricuspid Valve Surgery Due to Severe Tricuspid Regurgitation After Left-Sided Valvular Surgery

Objective: To analyze the factors affecting the early prognosis of patients undergoing repeat tricuspid valve surgery due to severe tricuspid regurgitation after left-sided valvular surgery. Method: We retrospectively analyzed 76 patients undergoing repeat tricuspid valve surgery due to severe tricuspid regurgitation after left-sided valvular surgery at Peking University International Hospital between October 2017 and February 2021. Patients were divided into two groups, according to preoperative weight control and whether the adjusted diuretic dose exceeded 40 mg of furosemide (or the equivalent dose). The factors affecting the early prognosis were analyzed through postoperative follow up. Results: Thirty-five male patients (46.1%), aged 57±13 years, were enrolled in the study. For the patients who received a preoperative same dose of furosemide ≥40 mg/day and a same dose of furosemide
