Late tricuspid regurgitation (TR) is a common complication after left-sided valve surgery (LSVS), which usually progresses slowly and results in right heart failure at terminal stage. Over the past 3 decades, with the advances in minimally invasive surgical techniques, operative mortality after reoperation for severe TR has significantly decreased from 30% to 3-8%, leading to a gradual shift from medical therapy alone to surgery in those patients. However, there has been no consensus on the clinical benefit of minimally invasive tricuspid surgery over medical therapy for severe TR after LSVS.
In this multi-center randomized controlled trial, patients with severe TR after LSVS will be recruited. The patients will be randomly assigned to surgery plus medical therapy (surgery group) or medical therapy alone (control group). The primary outcome will be a composite of all-cause mortality, re-admission for right heart failure or the composite. Furthermore, echocardiography-based measurement of right heart function, New York Heart Association functional class, liver and kidney function, and quality of life will be compared between the 2 groups. All outcomes will be assessed at baseline and 6, 12 and 24 months after randomization.
