Minimally Invasive Tricuspid Surgery vs Medical Treatment for Severe TR

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.
