AbstractPurpose of reviewTransthyretin amyloid cardiomyopathy (ATTR-CM) is a disease with high morbidity and mortality. This disease is significantly underdiagnosed and is more common than previously appreciated, particularly among older adults and people of African descent. This review discusses recent advances in the diagnosis and treatment for ATTR-CM.Recent findingsHistorically, ATTR-CM was diagnosed via endomyocardial biopsy, a resource-intensive and invasive approach. However, in most cases, ATTR-CM can now be diagnosed non-invasively using bone tracer cardiac scintigraphy, which may facilitate earlier diagnosis. In ...
AbstractPurpose of reviewRapid advancements in technology and electronic medical record systems have given rise to massive amounts of cardiac imaging data with the potential to alter medical practices. The rise of machine learning (ML) and radiomics – the concept that images contain invaluable data regarding disease processes beyond what the eyes can see – promises increased precision and accuracy to the current standard of care. Recent advancements in major cardiac imaging modalities, such as echocardiography, cardiac CT and cardiac MRI, h ave uncovered promising diagnostic and prognostic information through t...

AbstractCoronary artery bypass grafting improves survival in patients with ischemic cardiomyopathy, however, these patients are at high risk for morbidity and mortality. The role of viability testing to guide revascularization in these patients is unclear. Cardiac magnetic resonance imaging (CMR) has not been studied adequately in this population despite being considered a reference standard for infarct imaging. We performed a multicenter retrospective analysis of patients (n = 154) with severe left ventricular systolic dysfunction [ejection fraction (EF) 50% viability on CMR had a 47% reduct...

ConclusionMental stress decreased the123I-mIBG HMR, increased mismatch between sympathetic activity and myocardial perfusion, and increased the heterogeneity of123I-mIBG uptake in ICM patients, while there was no significant change in myocardial defect size or the heterogeneity of99mTc-Tetrofosmin perfusion. The changes observed in this proof-of-concept study may provide valuable information about the trigger –substrate interaction and the potential vulnerability for ventricular arrhythmias.
