Abstract

Transcatheter edge-to-edge repair (TEER) treats severe tricuspid regurgitation, but electrical complications from device-tissue interactions remain poorly characterized.
A 79-year-old woman developed postural ventricular arrhythmias after TriClip implantation. Electrocardiography was consistent with an ectopic origin in the posterior/inferior right ventricle, anatomically concordant with the posteroseptal clip. Orthostatic reduction in right ventricular volume may have induced dynamic clip-endocardium contact. Saline infusion abolished the arrhythmias. At 1 month, she remained asymptomatic despite unchanged device-to-septum distance on supine echocardiography, suggesting stabilization of the device-tissue interface over time.
As the first reported case of postural arrhythmia from mechanical TriClip-septal interaction, this addresses a gap in TEER literature regarding how orthostatic volume shifts trigger device-related complications.
Orthostatic volume shifts may provoke dynamic device-tissue contact and arrhythmias post-TEER. Careful clip positioning and vigilant postprocedural monitoring are essential, and stabilization of the device-tissue interface over time may allow conservative management.
