In LVNC, muscle in the heart's left ventricle — one of two lower chambers — becomes sponge-like, with extra space between the muscle tissues. These heart muscle changes can affect how the left chamber pumps blood and can allow blood clots to form in the chamber.
In some people, the cause of LVNC is from changes in specific genes (mutations). These gene changes can affect how the heart forms and can lead to left ventricular non-compaction cardiomyopathy.
These gene changes can be inherited from parent to child. Therefore, it is important to determine if the cause of your LVNC is secondary to gene changes.
