BACKGROUND: Severe tricuspid valve regurgitation (TR) is associated with high cardiovascular mortality. Safe and feasible interventional approaches to treat severe TR are of clinical relevance. The MitraClip is a device that has been approved by the US Food and Drug Administration (FDA) for the repair of mitral valve lesions. Percutaneous femoral venous access with fluoroscopic and echocardiographic guidance is used to deliver a cobalt-chromium clip to secure the mitral valve leaflets. We report on an 85-year-old man with tricuspid valve regurgitation who underwent percutaneous edge-to-edge tricuspid valve leaflet plication with the new, advanced MitraClip XTR System.
CASE REPORT: An 85-year-old man with severe TR due to annulus dilation of the right ventricle and short septal leaflet presented repeatedly at our hospital with severe right heart failure symptoms. Transesophageal echocardiography revealed severe TR with a large coaptation gap size of 10.6 mm. Percutaneous edge-to-edge valve repair with the new-generation MitraClip System XTR with wider clip arms could overcome the large coaptation gap. We achieved a strong reduction of TR after deploying 2 MitraClips XTR. The patient recovered quickly and has not been admitted to hospital due to heart failure symptoms since the intervention for more than 6 months.
CONCLUSIONS: Previous studies have shown the safety and effectiveness of the MitraClip device and supported FDA approval for tricuspid valve repair. This report of a patient with complex tricuspid regurgitation demonstrated the feasible use of the new MitraClip XTR System, which improved edge-to-edge tricuspid valve repair due to its increased span and improved grip.
