Transcatheter Tricuspid Valve Replacement in the Presence of Pacemaker Lead–Related Tricuspid Regurgitation and Complex Anatomy
Bibliographic record
Abstract
BACKGROUND: Cardiac implantable electronic device (CIED)-related tricuspid regurgitation (TR) is increasingly recognized, necessitating heart team assessment. Transcatheter tricuspid valve replacement (TTVR) is emerging as an option for inoperable patients with TR, requiring decisions on right ventricular lead management. CASE SUMMARY: A 76-year-old woman developed moderate to severe TR after pacemaker implantation, which was exacerbated by a second RV lead 8 years later, leading to torrential TR and recurrent heart failure hospitalizations. TR persisted despite lead extraction, and multimodality imaging revealed complex valve anatomy. TTVR was performed, yielding excellent echocardiographic results and improved quality of life. DISCUSSION: CIED and TR can coexist, obscuring the distinction between lead-related and lead-associated TR because of right ventricular remodeling. The heart team should determine lead management during transcatheter procedures. TTVR is a valuable option for massive gaps, severe tethering, or complex anatomy. TAKE-HOME MESSAGE: Collaborative management with electrophysiology as part of the extended heart team is key in CIED-related TR cases.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
