Background In patients with remarkably enlarged cardiac chambers and history of implantation of older types of mitral valve prosthesis, the considerations for reoperative tricuspid valve surgery are not limited to the risks of sternal reentry but also include the dilemma of whether to carry out prophylactic replacement of the normal functioning but outdated prosthesis or leave it in situ. Methods We reviewed our surgical strategy and postoperative 5-year follow-up findings in two patients who underwent redo tricuspid surgery 3 to 4 decades after mechanical mitral valve replacement. Both patients presented with significant symptoms of progressive right heart failure due to severe tricuspid regurgitation, despite optimal medical therapy. Results We found the beating-heart approach to be an effective and safe method for redo tricuspid surgery. Both first-generation mitral mechanical prostheses were not replaced and have remained well functional upon the patients’ postoperative 5-year follow-up, respectively. Conclusion For patients with normal functioning first-generation mechanical mitral prostheses, whether to prophylactically replace the prosthesis should be based on an individualized risk-benefit analysis.

Abstract We report a neonate with dilated cardiomyopathy and have echocardiographic findings consistent with “functional” tricuspid atresia. There was an echo-bright, plate-like tissue at the tricuspid valve position with no forward flow across it. This report underscores the role of right ventricle intracavitary haemodynamic influence on the tricuspid valve leaflet excursion and demonstrates a phenomenon of “pseudo or functional tricuspid atresia” mimicking tricuspid atresia in a patient with acute presentation of cardiomyopathy.

Background: Tricuspid valve replacement (TVR) is seldom performed in cardiac valve surgery, and there currently are no clinical guidelines as to which type of prostheses is better in tricuspid valve position. This meta-analysis was performed to compare the results of mechanical and biological prostheses for TVR. Methods: We searched the Pubmed, Cochrane, and Embase clinical trial databases to collect all related studies published from January 1, 2000 to July 31, 2020. A random-effects model was used to evaluate the odds ratios (OR) and its 95% confidence intervals (CI) of time-to-event related effects of the surgical procedures; every study’s quality was evaluated by the Newcastle-Ottawa Scale (NOS). Results: A total of 13 retrospective studies, including 1453 patients were analyzed. There were no statistically differences between mechanical and biological prostheses with respect to prosthetic valve failure [OR = 0.84, 95% CI(0.54, 1.28), P = .41], bleeding [OR = 0.84, 95% CI(0.54,1.28), P = .41], reoperation [OR = 1.02, 95% CI(0.58,1.78), P = .95], early mortality [OR = 1.35, 95% CI(0.82,2.25), P = .24] and long-time survival [OR = 1.09, 95% CI(0.70, 1.69), P = .70], but a significant difference can be seen in mechanical prostheses with a higher risk of thrombosis [OR = 0.17, 95% CI(0.05, 0.60), P = .006, I2 = 0%]. Conclusions: In tricuspid valve position, mechanical valve prostheses have a higher risk of thrombosis than biological prostheses, but no statistical differences between mechanical and biological prostheses with respect to prosthetic valve failure, bleeding, reoperation, early mortality, and long-term survival. The valve disease and patient’s age and risk factors are the most important considerations in the decision-making process. The more specific conclusion needs to be further proved by large-sample, multi-center, randomized, double-blind and control trials.
