Study design: Observational Study
Abstract: Background: Predictive value of perioperative cardiac computed tomography (CT) parameters, for long-term postoperative outcomes following tricuspid valve (TV) surgery is unclear. We investigated the prognostic value of perioperative cardiac CT-derived tricuspid annular and right ventricular (RV) parameters on long-term postoperative adverse outcomes after TV surgery. Methods: We prospectively enrolled 66 patients who underwent corrective TV surgery for tricuspid regurgitation between June 2019 and January 2021 and had preoperative cardiac CT. Postoperative cardiac CT was performed 6 months after surgery. RV volume parameters were analyzed on the preoperative and postoperative cardiac CT images; the TV annulus diameter was measured from the preoperative CT. Postoperative adverse outcomes included death from any cause, unplanned postoperative admission, residual tricuspid regurgitation (≥ moderate), or RV systolic pressure >50 mmHg on postoperative echocardiography performed postoperative 6 months or later. Cox proportional hazard regression analyses were performed to identify significant imaging parameters associated with postoperative adverse outcomes. Restricted mean survival time was compared between groups at postoperative timepoints of 1 and 2 years. Results: ) at postoperative 2-year timepoint (difference of 8.7 months, P<0.001). Conclusions: Perioperative cardiac CT imaging-based TAD and RV volume can provide independent prognostic information for postoperative adverse outcomes in patients undergoing TV surgery.
