CTICasesDehisced Tricuspid Annuloplasty Ring
Imaging findings
Chest radiograph and CT in a young patient with history of tricuspid valve repair show an abnormal, distorted, and bent configuration of the tricuspid annuloplasty ring. CT angiogram confirms complete dehiscence of the lateral portion of the ring from the tricuspid valve plane, resulting in severe tricuspid regurgitation.
Key takeaways
Tricuspid annuloplasty ring dehiscence is a mechanical complication of valve repair. Radiographically, a distorted or abnormally oriented ring on chest radiographs should raise suspicion for dehiscence, which can be confirmed with echocardiography or gated cardiac CT showing a gap between the ring and the valvular annulus.
