Introduction to Diseases of the Myocardium
The five cardiomyopathy phenotypes, why phenotype comes before etiology, and how echocardiography drives the diagnostic pathway, per the 2023 ESC guideline.
TutorialHypertrophic Cardiomyopathy
HCM's variants, the phenocopies that mimic it, LVOT obstruction mechanics, and how echo drives septal reduction therapy selection — per the 2021 BSE guideline.
TutorialDilated Cardiomyopathy
DCM's sex-specific diagnostic thresholds, the heart-failure differential it must survive, and the CRT and thrombus questions echo answers along the way.
TutorialRestrictive Cardiomyopathy
RCM's distinctive echo signature, why 'restrictive filling' isn't the same as the disease itself, and the principles that separate it from constriction.
TutorialArrhythmogenic Right Ventricular Cardiomyopathy (ARVC)
The 2010 Task Force echo criteria with real sensitivity/specificity data, the 'triangle' and 'quadrangle of dysplasia,' and why ARVC is a biventricular disease.
TutorialNon-Dilated Left Ventricular Cardiomyopathy (NDLVC)
The new 2023 phenotype absorbing what used to be scattered across DCM, ALVC, and left-dominant ARVC — and why sudden death risk here doesn't track with EF.
TutorialCardiac Amyloidosis
Why asymmetric hypertrophy doesn't exclude amyloid, the quantified apical sparing sign, and the three-tier likelihood report the 2023 BSE guideline recommends.
TutorialCardiac Hemochromatosis
Why wall thickness often isn't increased, the three patterns echo can show, and why T2* CMR — not echo — catches iron overload early enough to reverse it.
TutorialCardiac Sarcoidosis
Why sarcoidosis has no single echo phenotype, the basal septal thinning sign, and why a normal biopsy or a negative PET scan never fully excludes it.
TutorialEndomyocardial Fibrosis
EMF's two forms, the specific diagnostic pattern of Löffler endocarditis, and why this is an endocardial — not myocardial — route to restrictive physiology.
TutorialMyocarditis
Why no echo finding is pathognomonic, the transient edema-driven wall thickening that can mimic HCM, and the formal 2025 ESC diagnostic criteria.
