title: An unusual cause of pacemaker-induced severe tricuspid regurgitation.
abstract: Pacemaker (PM) induced tricuspid regurgitation (TR) is a common echocardiographic finding. Although mild or moderate TR is frequently observed, severe TR is rare. We report the exceptional observation of a severe TR due to leaflet malcoaptation occurring late after PM implantation and in the following weeks after an aortic valve replacement. Our hypothesis is that the aortic valve surgery has been responsible for conformational changes between cardiac cavities, tricuspid valve and PM leads resulting in a severe TR.
