Common questions in this guide

What is Familial Isolated Dilated Cardiomyopathy (FIDC)?
FIDC is a genetic condition that causes the heart muscle to stretch and weaken. While the diagnosis can be overwhelming, it is highly manageable with modern medical therapies and proper monitoring.
How is FIDC treated?
Treatment typically involves the four pillars of heart medication, which work together to heal and support the heart muscle. In some cases, your doctor may recommend an implantable cardioverter-defibrillator (ICD) for added protection.
Do my family members need to be tested for FIDC?
Because FIDC is genetic, your parents, siblings, and children may be at risk. Your care team will likely recommend cascade screening and working with a genetic counselor to protect your relatives.
What genes are associated with FIDC?
FIDC is often driven by mutations in specific genes that affect heart muscle function. The most common genes involved include TTN, LMNA, and FLNC.
