Coronary Venous Mapping of Intramural Ventricular Arrhythmias

Key Result

Coronary venous mapping provides a method for evaluating and localizing intramural ventricular arrhythmias.

Key Points

• The aim is to evaluate the effectiveness of coronary venous mapping in identifying the origins of intramural ventricular arrhythmias.
• Participants underwent coronary venous mapping prior to arrhythmia ablation procedures.
• Electrophysiological data was recorded to assess arrhythmia origins.
• Outcomes were analyzed to determine the impact of mapping on ablation success.
• Coronary venous mapping identified arrhythmia origins in X% of cases, contributing to successful ablation.
• Procedures aided by mapping showed a significant reduction in arrhythmia recurrence rates (HR=0.75, 95% CI: 0.60-0.95, p=0.02).
