Q: What is the most common cardiomyopathy type in children? A: Dilated cardiomyopathy (DCM) - ~60% Tags: cardiomyopathy, dcm, high-yield
Q: What percentage of "idiopathic" DCM have genetic cause? A: ~30% Tags: cardiomyopathy, genetics, high-yield
Q: Should genetic testing be performed in pediatric cardiomyopathy? A: YES - recommended for ALL children with cardiomyopathy Tags: cardiomyopathy, genetics, high-yield
Q: What are phenocopies of HCM that need specific treatment? A: Fabry (ERT), Pompe (ERT), Danon (early transplant), Noonan, PRKAG2 Tags: cardiomyopathy, phenocopies, high-yield
Q: What mutation in DCM is high-risk for sudden death? A: LMNA mutation (especially with conduction disease) - ICD indicated Tags: cardiomyopathy, lmna, icd, high-yield
Q: What characterizes restrictive cardiomyopathy (RCM)? A: Diastolic dysfunction, biatrial enlargement, poor prognosis, high PH risk Tags: cardiomyopathy, rcm
Q: What is ARVC? A: Arrhythmogenic cardiomyopathy - fibrofatty replacement; RV classically but LV common; exercise-related SCD risk Tags: cardiomyopathy, arvc
Q: What is LVNC? A: Left ventricular noncompaction - excessive trabeculation; may overlap with DCM; arrhythmia and thromboembolism risk Tags: cardiomyopathy, lvnc
Q: What causes tachycardia-induced cardiomyopathy? A: Uncontrolled sustained tachycardia; REVERSIBLE with rate/rhythm control Tags: cardiomyopathy, tachycardia-induced
