Residual or recurrent tricuspid regurgitation and RVOT-FS after surgical repairDear Editor, Hu and colleagues provide clinically relevant evidence linking preoperative right ventricular dimensions with early tricuspid regurgitation (TR) after surgical repair for functional TR [1].Among 210 patients, 77 (36.7 %) were classified as having moderate-to-severe TR within 6 months, and right ventricular outflow tract fractional shortening (RVOT-FS) was the only echocardiographic variable that remained significant in the multivariable model.However, uncertainty in outcome definition, internal reporting inconsistencies, and limitations of model specification complicate the interpretation of RVOT-FS as an independent predictor.The timing and definition of "recurrence" require clarification.The Methods state that postoperative echocardiography was performed 3-6 months after surgery, whereas TR was detected at a median of 95 days (IQR, 23-125).An IQR lower bound of 23 days is incompatible with the stated surveillance window, suggesting that either the timing summary or the follow-up protocol was reported incorrectly.The authors should describe the actual distribution of examination times, whether earlier examinations were symptom-driven, and which examination defined the outcome when multiple postoperative echocardiograms were available.More fundamentally, no immediate postoperative or predischarge echocardiographic result was reported to establish that TR initially improved to mild or l...
