Key result
Endocardial SRV lead implantation via VersaCross successfully delivers CRT and improves symptoms in one patient.
Why the study?
SRV cardiomyopathy frequently complicates d-transposition of the great arteries following atrial switch repair, but CRT may be difficult to achieve conventionally through coronary sinus lead implantation.
Does endocardial systemic right ventricular lead implantation for CRT improve symptoms and cardiac indices in a patient with d-transposition of the great arteries and prior Mustard procedure?

Does endocardial systemic right ventricular lead implantation for CRT improve symptoms and cardiac indices in a patient with d-transposition of the great arteries and prior Mustard procedure?
Endocardial systemic right ventricular lead implantation via a transbaffle approach is a feasible and effective alternative for CRT in patients with d-transposition of the great arteries when coronary sinus lead placement is unsuitable.
No takes yet. Share an insight, caveat, or question.
May support endocardial RV lead CRT when coronary sinus access fails in d-TGA; hypothesis-generating and requires prospective validation.
Parekh et al. (2025) conducted a case report in d-transposition of the great arteries with prior Mustard procedure and progressive dyspnea (n=1). Endocardial SRV lead implantation via VersaCross radiofrequency wire system for CRT was evaluated on QRS morphology and symptom improvement. Endocardial systemic right ventricular lead implantation via the VersaCross system successfully delivered cardiac resynchronization therapy, improving symptoms and cardiac indices in a 58-year-old man.
