    Abstract:
    A best evidence topic in adult valvular surgery was written according to a structured protocol. The question addressed was 'Does concomitant tricuspid annuloplasty increase the perioperative mortality and morbidity when correcting left-sided valve disease?' A total of 561 papers were found using the reported search, of which 12 presented the best evidence to answer the clinical question. The authors, country, journal, date of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Among these 12 papers, there were nine retrospective studies, two cohort studies and one randomized controlled trial (RCT). Overall, additional tricuspid valve (TV) repair takes more time during operations, particularly with a ring annuloplasty method. The mean aortic cross-clamping times were 57-83 min without associated tricuspid repair and 62-100 min with, and cardiopulmonary bypass times without and with repair were 82-124 and 90-174 min, respectively. A study of 624 patients who had undergone isolated mitral valve (MV) surgery and MV surgery plus TV repair showed more female and atrial fibrillation patients in the tricuspid valve plasty (TVP) group, but no increase in the 30-day mortality was found. One RCT, presenting similar patient baseline characteristics, also found no difference in the hospital mortality rates between the TVP group and the non-TVP group. Another 10 studies also demonstrated no statistically significant differences in perioperative mortality. In a cohort study of 311 patients undergoing MV repair with or without tricuspid annuloplasty, postoperative complications, such as bleeding, stroke, pacemaker, haemofiltration and myocardial infarction, all showed no statistically significant differences in the two groups. One study retrospectively analysed a large number of patients undergoing either isolated left-sided valve surgery or a concomitant TV repair, and there were no statistically significant differences regarding major complications (bleeding, pacemaker, respiratory insufficiency, and renal failure). Moreover, another three studies also found no statistically significant differences in terms of bleeding, pacemaker, wound infection, neurological deficit, pericardial effusion, low cardiac output syndrome and dialysis. In conclusion, there is good evidence to support that tricuspid annuloplasty is a low-risk procedure and concomitant TV repair does not significantly increase the perioperative mortality and morbidity when correcting left-sided valve disease.
