Why the study?
Does voltage mapping efficiently detect left ventricular substrate in patients with arrhythmogenic right ventricular cardiomyopathy?
Does voltage mapping efficiently detect left ventricular substrate in patients with arrhythmogenic right ventricular cardiomyopathy?
Left ventricular substrate in ARVC is poorly identified by current voltage mapping strategies despite having a similar density of abnormal activity as RV fat, highlighting the need for alternative diagnostic approaches.
Voltage mapping may miss LV substrate in ARVC; this cohort study leaves open whether alternative mapping improves detection.
LV substrate is frequent in arrhythmogenic RV cardiomyopathy, but poorly identified by current diagnostic strategies. Left-sided arrhythmias are more frequent in case of LV involvement. LV fat hosts the same density of local abnormal ventricular activity as RV fat, but is less efficiently detected by voltage mapping. These results support the need for alternative diagnostic strategies to identify LV dysplasia.
