Key result
Pacemaker lead extraction resulted in traumatic tricuspid valve injury, characterized by a flail anterior leaflet, torn papillary muscle, and severe tricuspid regurgitation.
Case Report (n=1)
Echocardiography is crucial for identifying severe traumatic tricuspid valve injury, such as flail leaflet and torn papillary muscle, following pacemaker lead extraction.
Supports echocardiography to detect traumatic tricuspid injury after lead extraction; hypothesis-generating pending larger studies.
Video 1 (A) Parasternal long axis view of right ventricular inflow and (B) apical four-chamber view show a flail anterior tricuspid valve leaflet and subvalvular apparatus. Video 2 (A) Colour Doppler parasternal long axis view of right ventricular inflow and (B) colour Doppler apical four-chamber view show severe tricuspid regurgitation. Video 3 Hepatic venous colour Doppler imaging shows marked systolic flow reversal (red colour) into the hepatic vein, consistent with severe tricuspid regurgitation (TR). Video 4 (A) Two-dimensional transesophageal echocardiographic images confirm the presence of a flail anterior tricuspid valve leaflet and the “torn off” anterior papillary muscle. (B) Colour Doppler imaging confirms the presence of severe, “wide-open” tricuspid regurgitation. Video 5 Three-dimensional transesophageal echocardiographic images from an en-face right atrial perspective show the flail tricuspid valve leaflet and the “torn off” anterior papillary muscle prolapsing into the right atrium.

Anderson et al. (2020) conducted a case report in Traumatic tricuspid valve injury (n=1). Pacemaker lead extraction was evaluated. Pacemaker lead extraction resulted in traumatic tricuspid valve injury, characterized by a flail anterior leaflet, torn papillary muscle, and severe tricuspid regurgitation.
