What is the prevalence of left ventricular non-compaction in adults?
The use of newer imaging technologies like CMR has led to a higher detected prevalence of left ventricular non-compaction in adults, raising concerns for overdiagnosis and overtreatment.
Left ventricular non-compaction in adult populations is a poorly defined entity which likely encompasses both physiological adaptation and pathological disease. There is a higher prevalence with the introduction of newer imaging technologies, specifically CMR imaging, which identify LVNC changes more readily. The clinical significance of these findings remains unclear; however, there is significant potential for overdiagnosis, overtreatment, and unnecessary follow-up.
