Popis: | Introduction Isolated tricuspid valve surgery is an uncommon operation. Historical reports, including a previous review from our unit, demonstrated high morbidity and mortality associated with this operation. Many of these patients had severely impaired right ventricular function at the time of the surgery. Since our previous review, we have actively encouraged our local cardiologists to refer patients with severe isolated tricuspid disease for surgery before right ventricular remodelling occurs. This present study was performed to assess our current results. Material and Methods A prospectively-maintained hospital database was used to identify all adult non-congenital patients receiving standalone tricuspid valve repair or replacement at New Zealand’s largest cardiothoracic surgical unit from July 2011 to July 2019. Additional demographic and clinical data were collected by review of patient electronic records. Results During the 8-year study period, a total of 50 patients underwent isolated tricuspid valve surgery. Most patients were operated on for functional (40%) or rheumatic (30%) tricuspid disease. The majority of patients underwent surgery when the right ventricular function preoperatively was normal (30%) or mildly/moderately impaired (60%). Over half the patient sample (56%) underwent valve replacement. The 30-day mortality rate and stroke rate were 6% and 2% respectively. The medium-term survival was 80% at 4 years mean follow-up. Conclusion Isolated tricuspid surgery is no longer a high mortality operation when it is performed on patients who have preserved right ventricular function. |
