Abstract
BACKGROUND
Adults with repaired tetralogy of Fallot (rTOF) frequently develop right heart failure, most commonly related to pulmonary regurgitation. Tricuspid regurgitation (TR) is an underrecognized contributor. Transcatheter edge-to-edge repair (TEER) has emerged as an alternative to surgery, but evidence in congenital heart disease remains limited.
CASE SUMMARY
We report the first case of isolated tricuspid valve repair using TriClip in an adult with rTOF and severe symptomatic TR. Preprocedural transesophageal echocardiography demonstrated type IIIb anatomy with a 6-mm coaptation gap. The initial clip entrapment resulted in chordal rupture and transient TR worsening. Two additional clips were successfully implanted, leading to significant TR reduction and clinical improvement.
DISCUSSION
This case highlights both the feasibility and technical challenges of TEER in complex congenital anatomy.
TAKE-HOME MESSAGES
TR contributes to right heart failure in rTOF. The tricuspid subvalvular apparatus may be fragile; nevertheless, TEER remains feasible and clinically beneficial in selected patients.
