Hi James, I moved your message and question about left ventricular non-compaction (LVNC) to this previous discussion of the same name. I did this so that you can connect with @charlottegrace and read the excellent information provided by Kanaaz. Please scroll through the past posts.

Since LNVC is a genetic cardiomyopathy, I'm wondering if you've investigated genetic testing to determine the diagnosis? Do other family members have a history of heart issues?
