Key result
IVUS-guided wiring and an anchor balloon enable successful LV lead implantation in PLSVC.
Why the study?
Cardiac resynchronization therapy lead implantation is often difficult in patients with coronary sinus anomalies.
Intravascular ultrasound-guided wiring and anchor balloon technique may facilitate left ventricular lead implantation in challenging cases with persistent left superior vena cava.
No takes yet. Share an insight, caveat, or question.
May aid select PLSVC cases; hypothesis-generating and requires prospective validation before broader use.
Tanaka et al. (2023) studied this question. Intravascular ultrasound-guided wiring and an anchor balloon technique enabled successful left ventricular lead implantation in a patient with a persistent left superior vena cava.
