Key result
Direct visualization using a fiberoptic endocardial visualization catheter identified a Thebesian valve in 54% of 98 patients undergoing biventricular device implantation.
Why the study?
Does direct visualization using a fiberoptic endocardial visualization catheter characterize coronary sinus ostium anatomy and facilitate cannulation during biventricular pacemaker implantation?

Does direct visualization using a fiberoptic endocardial visualization catheter characterize coronary sinus ostium anatomy and facilitate cannulation during biventricular pacemaker implantation?
Direct visualization using a fiberoptic catheter reveals that over half of patients have Thebesian valves, which can be successfully traversed for biventricular pacing even when covering most of the ostium.
Anh et al. (2007) conducted an observational in Patients undergoing implantation of biventricular devices (n=100). Fiberoptic endocardial visualization catheter (EVC) was evaluated on Presence of a Thebesian valve at the coronary sinus ostium. Direct visualization using a fiberoptic endocardial visualization catheter identified a Thebesian valve in 54% of 98 patients undergoing biventricular device implantation.
