RESUMO
BACKGROUND: Transcatheter tricuspid valve repair using the edge-to-edge-technique (TEER) has emerged as an alternative therapy in patients with severe tricuspid regurgitation (TR) and high surgical risk. This study aimed to evaluate the feasibility and efficacy of tricuspid valve TEER in patients with cardiac implanted electric devices (CIEDs). METHODS: All patients who underwent tricuspid valve TEER at our center were retrospectively included. Patients were classified according to the presence of CIEDs. Procedure success was defined as implantation of at least one clip and the reduction of TR of at least one grade. Procedure success and intrahospital outcome were compared between the two groups. RESULTS: One-hundred and six consecutive patients underwent tricuspid TEER (age 80.1 ± 6.4 years, male = 42; 39.6%). Among them, 25 patients (23.6%, age 80.6 ± 7.3 years, male = 14; 56%) had CIEDs. Patients with CIEDs had a significantly lower left ventricular ejection fraction (LV-EF) compared to those without CIEDs (47.2 ± 15% vs. 56.2 ± 8.2%, p = 0.004, respectively). Moreover, arterial hypertension was more common in patients with CIEDs (96% vs. 79%, p = 0.048). The success of the procedure did not differ between the non-CIED vs. CIED group (93.8% vs. 92%, p = 0.748). Furthermore, the number and position of implanted clips, the duration of the procedure, the post-procedural pressure gradient across the tricuspid valve, and post-procedural TR severity were comparable between both groups. CONCLUSION: Tricuspid valve TEER is feasible and efficient in patients with CIEDs. The success of the procedure, as well as the intrahospital outcome were comparable between patients with and without CIEDs.
RESUMO
BACKGROUND AND CASE SUMMARY: We report a case of a 76-year-old female who was admitted to our hospital because of dyspnoea caused by a known high-grade tricuspid valve regurgitation (TR). The patient received an edge-to-edge reparation of the tricuspid valve 1 month before the current admission using the TriClip XTR (Clip) system. The post-interventional echocardiographic results were satisfying, and the patient was discharged with TR grade I. At this new admission, the echocardiographic control showed a missing Clip on the tricuspid valve with a recurrent high-grade regurgitation. Fluoroscopy showed the dislocated Clip at the level of the femoral vein. This was also confirmed using Duplex sonography with no signs of thrombosis or embolization. The challenge was how to extract the Clip using endovascular methods as the patient refused any kind of surgical removal. We managed to remove the 20 × 10 mm big clip using transfemoral access and an endovascular snare system. No post-interventional complications were registered. The patient was discharged after the intervention with a new scheduled Clip procedure. DISCUSSION: This case shows a possible safe and challenging alternative to removing dislocated Clip from the femoral vein. Experienced operators are required to have the knowledge and skills to manage these possible procedural complications using the appropriate apparatus. A surgical technique would be, in this case, common practice, however as the patient declined surgical intervention, the endovascular approach was the alternative option.
