A Significant Improvement in Exercise Tolerance and Liver Stiffness after Valve Replacement Surgery for Lead-related Tricuspid Regurgitation: A Case Report.

We herein report a case of pacemaker lead-related tricuspid regurgitation in a repaired congenital heart disease patient, with a significant improvement in exercise tolerance and liver stiffness after surgery. Optimizing the timing of invasive procedures for tricuspid regurgitation is challenging because of an insufficient ability to predict the outcome, and percutaneous therapies have shown promising advancements in recent years. In this case, close monitoring with abdominal ultrasound and echocardiography facilitated our ability to select the optimal timing for surgical intervention.
