OBJECTIVES: Tricuspid valve insufficiency (TI) following cardiovascular surgery causes right-side heart failure and hepatic failure, which affect patient prognosis. Moreover, the benefits of reoperation for severe tricuspid insufficiency remain unclear. We investigated the surgical outcomes of reoperation in TI. METHODS: From the Japan Cardiovascular Surgery Database (JACVSD), we extracted cases who underwent surgery for TI following cardiac surgery between January 2006 and December 2011. We analysed the surgical outcomes, specifically comparing tricuspid valve replacement (TVR) and tricuspid valve plasty (TVP). RESULTS: Of the 167 722 surgical JACVSD registered cases, reoperative TI surgery occurred in 1771 cases, with 193 TVR cases and 1578 TVP cases. The age and sex distribution was 684 males and 1087 females, with an average age of 66.5 ± 10.8 years. The overall hospital mortality was 6.8% and was significantly higher in the TVR group than in the TVP group (14.5 vs 5.8%, respectively; P < 0.001). Incidences of dialysis, prolonged ventilation and heart block were also significantly higher in the TVR group than in the TVP group. Logistic regression analysis revealed that the risk factors of hospital mortality were older age, preoperative renal dysfunction, preoperative New York Heart Association Class 4, left ventricular dysfunction and TVR. CONCLUSIONS: Surgical outcomes following reoperative tricuspid surgery were unsatisfactory. Although TVR is a last resort for non-repairable tricuspid lesions, it carries a significant risk of surgical mortality. Improving the patient's preoperative status and opting for TVP over TVR is necessary to improve the results of reoperative tricuspid surgery.
