CARDIAC IMPLANTABLE ELECTRONIC DEVICE-INDUCED TRICUSPID REGURGITATION: IMPLICATIONS AND MANAGEMENT

Massachusetts General Hospital, Boston, Massachusetts, USA

Tricuspid regurgitation (TR) secondary to cardiac implantable electronic devices (CIEDs) has been well documented and is associated with worse cardiovascular outcomes. A variety of mechanisms have been proposed including lead-induced mechanical disruption of the tricuspid valvular or subvalvular apparatus and pacing-induced electrical dyssynchrony. The document emphasizes the role of three-dimensional echocardiography in accurately identifying the etiology of TR and the importance of regular monitoring in patients with CIED-induced TR to track changes in severity and function.
