Optimizing transseptal puncture guided by three-dimensional mapping: the role of a unipolar electrogram in a needle tip

EuropacePublished Observational cohort study with derivation and validation cohorts

Authors' conclusion

In most patients, fluoroless 3D-TSP was successfully achieved using changes in the COI on the UEGM tip.

Study context

Population
Patients undergoing 3D electroanatomic mapping-guided transseptal puncture
Comparison
Derivation vs Validation
  • Derivationn = 102
Outcome
FO identification by COI changes on UEGM tip; successful 3D-TSP via workflow

Performance

As reported in the abstract

Current of injury (COI) changes identified the foramen ovalis (FO) (derivation cohort, vs 3 minor criteria)

99%

101/102

Successful 3D-TSP through the workflow (validation cohort)

99.9%

1042/1043
