A Novel Myocardial Impedance Mapping System for Ablation of Post-infarction Ventricular Arrhytmias in Humans

NCT04000412 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 25

Last updated 2019-06-27

No results posted yet for this study

Summary

Precise identification of the infarct scar is essential for successful catheter ablation of ventricular arrhythmias in patients with chronic myocardial infarction. Voltage mapping of endocardial electrograms is currently used to delineate the necrotic scar but this is influenced by the direction of the activation wave front and is not sensitive enough to differentiate distinct degrees of transmural injury in the scar. Mapping of local myocardial electrical impedance may overcome these limitations.

Conditions

  • Ventricular Arrythmia
  • Infarction, Myocardial

Interventions

DEVICE

CardioZ multifrequency impedance recording system

Patients will be submitted to mapping of both voltage and tissue impedance. The accuracy of the two maps identifying the extent and transmurality of the infarction will be assesssed by gadolinium imaging.
