Timing of Referral of Patients With Severe Isolated Tricuspid Valve Regurgitation to Surgeons (from a French Nationwide Database).

Series evaluating the results of isolated tricuspid valve surgery (ITVS) are rare and often limited by small sample size, selection bias, and/or long period of enrollment. Based on a mandatory administrative national database, we collected all consecutive ITVS performed in France during a 2-year period (2013 and 2014), the type of intervention, clinical profile, and in-hospital mortality and complications. During the 2-year period, 241 patients underwent an ITVS in France (84 repairs and 157 replacements). In-hospital mortality was high (10%), and most patients experienced at least 1 complication (65%) with a 19% rate of major complications (death, need for dialysis, or need for mechanical support using extracorporeal membrane oxygenation). Consequently, hospital duration was remarkably long (26 ± 40 days). Congestive heart failure at presentation was associated with mortality and major complications rates (both p = 0.01). In conclusion, in a contemporary and consecutive series, ITVS was associated with a high mortality and morbidity predicted by clinical presentation at baseline. Our results suggest that patients are often referred too late and that an earlier intervention may improve immediate and possibly midterm outcomes. With the availability of transcatheter therapies in a near future, optimal timing of intervention in this population will be of utmost importance.
