Key result
Improved transseptal catheterization achieves a 97% success rate in patients with aortic valve replacement.
Why the study?
Performing retrograde left ventricular catheterization is difficult in patients with aortic valve replacement, necessitating improved catheterization methods.
Does an improved transseptal catheterization method improve procedural success in patients with an aortic valve replacement?
Observational (n=32)
Does an improved transseptal catheterization method improve procedural success in patients with an aortic valve replacement?
A modified transseptal catheter with a pig-tail tip and 270-degree curvature provides a highly successful and safe method for left ventricular catheterization in patients with prior aortic valve replacement.
No takes yet. Share an insight, caveat, or question.
Should not yet change practice in post-AVR patients; hypothesis-generating for modified transseptal access.
Kawachi et al. (1983) conducted an observational in Aortic valve replacement (n=32). Improved transseptal catheterization (modified Brockenbrough method) was evaluated on Success rate of catheterization. An improved transseptal catheterization method achieved a 97% success rate in 32 patients with an aortic valve replacement.
