Key result
CARTO 3-guided 3D transseptal puncture safely facilitates LV endocardial lead implantation after tricuspid valve replacement.
Why the study?
Ventricular lead implantation is difficult after tricuspid valve replacement due to right atrial abnormalities that complicate conventional coronary sinus lead placement, necessitating safe alternatives for LV endocardial lead implantation.
Does left ventricular endocardial lead implantation via total three-dimensional transseptal puncture provide a safe and effective pacing method in a patient with a mechanical tricuspid valve and right atrial enlargement?

Does left ventricular endocardial lead implantation via total three-dimensional transseptal puncture provide a safe and effective pacing method in a patient with a mechanical tricuspid valve and right atrial enlargement?
Total 3D transseptal puncture guided by the CARTO 3 system offers a feasible and safe approach for left ventricular endocardial lead implantation in patients with prior tricuspid valve replacement and right atrial enlargement.
Gao et al. (2023) conducted a case report in Bradyarrhythmia after tricuspid valve replacement (n=1). Left ventricular endocardial lead implantation via total three-dimensional transseptal puncture under CARTO 3 system guidance was evaluated on Successful implantation and pacing parameters. Total three-dimensional transseptal puncture under CARTO 3 guidance successfully facilitated left ventricular endocardial lead implantation without complications in a patient with prior tricuspid valve replacement.
