Implication

May shorten intraoperative bypass time for VT mapping; leaves open whether it improves outcomes in prospective studies.

Key Points

To enhance intra-operative mapping techniques for ventricular arrhythmias during surgical procedures.
Modified a cardiac mapping system to provide epicardial maps during surgery.
Incorporated features like a battery-operated multiplexer and adjustable electrogram gain.
Maintained spatial resolution of 0.5 cm and temporal resolution of 8.3 ms.
Reduced cardiopulmonary bypass time due to instantaneous analysis of epicardial activation information.
Enabled mapping of short salvos and polymorphic runs of ventricular tachycardia intra-operatively.

Population

Patients undergoing surgical treatment of ventricular arrhythmias

Intervention

Modified on-line cardiac mapping system for intra-operative epicardial mapping

Outcome

Epicardial maps of ventricular arrhythmias and cardiopulmonary bypass time

A modified on-line cardiac mapping system enables real-time intra-operative mapping of polymorphic ventricular tachycardia and reduces cardiopulmonary bypass time.
