← Back to Clinical Mastery Series

The Amyloid Series synthesizes content from cardiology, nephrology, hematology, and hemodynamic physiology into a cohesive educational pathway. These five reviews are designed to be read in sequence, building from ATTR cardiac amyloidosis through monoclonal protein interpretation, echocardiographic pitfalls, hemodynamic assessment, and cardiac-predominant AL disease. Each module integrates evidence from landmark trials, clinical case data, and practical decision frameworks.

Recommended Reading Order

1ATTR Cardiac Amyloidosis

ATTRwt prevalence in HFpEF (10–15%), the preserved EF trap, PYP scintigraphy and the Gillmore algorithm, tafamidis/acoramidis/gene silencers, and the 13-month median diagnostic delay.

ATTR-CM HFpEF PYP Scan

Comprehensive review

2Monoclonal Protein Interpretation

FLC reference ranges by eGFR (iStopMM), MASS-FIX panel structure, when to order SPEP vs immunofixation vs FLC, kappa vs lambda patterns, Mayo MGUS risk stratification, and SLiM criteria.

FLC MASS-FIX MGUS

Comprehensive review

3Misleading Echo in Infiltrative Cardiomyopathy

EF is a fraction not output, EF-CO dissociation with calculation examples, diastolic parameters (e’ velocity, E/e’), apical sparing strain, what echo cannot tell you, and when RHC is mandatory.

Echo GLS Diastology

Comprehensive review

4RHC in Amyloidosis: Hemodynamic Patterns

Restrictive physiology hemodynamic profile, Forrester classification, RA pressure and diuretic resistance, PCWP interpretation, and the restrictive vs constrictive vs HFpEF vs tamponade comparison.

RHC Hemodynamics Restriction

Comprehensive review

5Cardiac-Predominant AL Without Nephrotic Proteinuria

20–30% of AL presents cardiac-predominant, lambda germline variants targeting myocardium, proteinuria phenotyping, cardiac vs hepatic ascites (SAAG framework), and FLC interpretation in CKD.

AL Amyloid Cardiac Lambda
