Background: Amyloid cardiomyopathy progresses more rapidly and has different manifestations than more common cardiomyopathies. Nevertheless, survival of selected cardiac amyloid patients after orthotopic heart transplantation (OHT) followed by autologous stem cell transplant is similar to other restrictive cardiomyopathies. The importance of clinical presentation and pre-transplantation characteristics on outcome in patients with AL amyloid cardiomyopathy evaluated for heart transplantation is still not well defined. Methods: The impact of echocardiographic, hemodynamic, and clinical parameters on outcome in 46 patients evaluated for OHT and enrolled in the International Consortium for Cardiac Amyloid Transplant (iCCAT) database was studied. Cox proportional hazards models of time to death were used. End point was death after transplant evaluation censored at transplant. Results: The median age at the time of transplant evaluated was 57.6 (+/- 9.6) years, and the mean time from presentation to listing was 27 (+/- 26) days. 19 (41%) patients underwent OHT after an average wait time of 72 days. Univariate risk factors associated with death after initial evaluation were cardiac output (p=0.012), right ventricular stroke work index (p=0.033), left ventricular end diastolic dimension (p=0.024), left ventricular outflow tract velocity time integral (p=0.019), mean arterial pressures (p=0.005), NT pro-BNP (p=0.007), presence of pleural effusion (p=0.005), as well as elevated kappa and lambda serum free light chain concentrations (p=0.004). Whereas left ventricular ejection fraction did not correlate with death after evaluation, increased right ventricular wall thickness remained a strong mortality predictor in a multivariate model with light chain difference and cardiac output (HR 1.6 for every 1 mm increase in thickness, p=0.017). Conclusions: Pleural involvement, high light chain burden, and right ventricular infiltration predicted death while awaiting a donor organ and may be markers of more systemic disease. Ultimately, this could affect transplant candidate selection and allocation strategies.

Cardiovascular imaging is key for the assessment of patients with heart failure. Today, cardiovascular magnetic resonance imaging plays an established role in the assessment of patients with suspected and confirmed heart failure syndromes, in particular identifying aetiology. Its role in informing prognosis and guiding decisions around therapy are evolving. Key strengths include its accuracy; reproducibility; unrestricted field of view; lack of radiation; multiple abilities to characterise myocardial tissue, thrombus and scar; as well as unparalleled assessment of left and right ventricular volumes. T2* has an established role in the assessment and follow-up of iron overload cardiomyopathy and a role for T1 in specific therapies for cardiac amyloid and Anderson–Fabry disease is emerging.

Infiltrative cardiomyopathies include a variety of disorders that lead to myocardial thickening resulting in a constellation of clinical manifestations and eventually heart failure that could be the first clue to reach the diagnosis. Among the more described infiltrative diseases of the heart is amyloid cardiomyopathy. The disease usually presents with subtle, nonspecific symptoms. Herein, we illustrate a case of recurrent syncope as the initial presenting symptom for systemic amyloid with polyneuropathy and cardiomyopathy as a cause of syncope. The article illustrates the role of advanced cardiac imaging in the diagnosis of the disease with a focused literature review. We also highlight the role of early, shared decision-making between patient, family, and medical team in the management of cardiac amyloidosis.

Background: Transthyretin amyloid cardiomyopathy (ATTR-CM) is one of the most common types of cardiac amyloidosis. Amyloid cardiomyopathy more commonly affects men, elderly, and 3% to 4% of the African-American population. ATTR-CM suspicion and diagnosis is challenging; however, awareness of the disease is increasing, and best practices to identify it are being proposed. The approach to suspected cases of ATTR-CM relies on the presence of heart failure, red flag signs and symptoms, and age >65 or >70 for men and women respectively. Little is known about cases when it presents in early ages. Case: We report a 62-year-old African American male with past medical history of hyperlipidemia, prostate cancer, hypertension, bilateral carpal tunnel surgery that had debuted with a cardiac arrhythmia at age 55 and was diagnosed with heart failure several years later. Restrictive cardiomyopathy was suspected, and genetic screening was sent for ATTRm which confirmed a pathogenic trasnthyretin gene mutation. Endomyocardial biopsy was performed which confirmed cardiac amyloid deposition. Discussion: ATTR-CM is a rare disease with an increasing prevalence. Cases with out of proportion signs and symptoms of heart failure with preserved ejection fractions should raise the suspicion of ATTR-CM despite age.
