Complication Management for Transcatheter Tricuspid Annuloplasty Dislocation

Severe secondary tricuspid regurgitation (TR) is increasingly recognized as a major contributor to heart failure symptoms and mortality, particularly in elderly patients with complex comorbidities. Transcatheter tricuspid valve interventions have emerged as promising alternatives for these challenging cases. We report the cases of 2 patients with severe dyspnea and leg edema who were diagnosed with torrential TR. Both patients initially underwent transcatheter annuloplasty using the Cardioband system (Edwards Lifesciences), which led to significant improvements in TR severity and clinical symptoms. However, both experienced device dislocation and recurrent torrential TR within months. Subsequent complication management included orthotopic and heterotopic transcatheter tricuspid valve replacement, resulting in marked clinical improvement. This report underscores the potential and challenges of transcatheter therapies for severe functional TR, highlighting the importance of careful patient selection, close monitoring, and adaptive treatment strategies to optimize outcomes.
