Cardioblate Detect Surgical Pacing and Mapping Tool

Conduction Block Confirmation

Summary

Pace and Sense

The Cardioblate® Detect® tool enables analysis of cardiac electrical activity and confirms conduction block with temporary pacing and sensing during surgical ablation procedures.

Pacing

  • Establish atrial capture by pacing from the area to be isolated.
  • Once the isolation lesion has been created, pace with the Cardioblate MAPS device from the same location as before to attempt atrial capture.
  • Conduction block is proven if atrial capture is not obtained (no corresponding atrial rate change as established initially).

Sensing

Monitor atrial electrogram (EGM) pre- and post-ablation to confirm entrance block.

  • Before creating the isolation lesion, monitor atrial EGM in the area to be isolated.
  • After the lesion has been created, monitor atrial EGM on both sides of the lesion for comparison to each other and those measured previously.
  • Conduction block is proven by absence or reduction of electrical activity in the area isolated by the ablation lesion when compared to atrial activity outside that area.

Important Safety Information

Possible complications related to the ablation of cardiac tissue in combination with open heart surgery are: tissue perforation, extension of extracorporeal bypass, perioperative heart rhythm disturbances (atrial and/or ventricular), postoperative embolic complications, pericardial effusion or tamponade, injury to the great vessels, valve leaflet damage, conductions disturbances (SA/AV node) and acute ischemic myocardial event.
