Diagnostic and Prognostic Value of Right Ventricular Fat Quantification from Computed Tomography in Arrhythmogenic Right Ventricular Cardiomyopathy.

In arrhythmogenic right ventricular cardiomyopathy (ARVC) non-invasive scar evaluation is not included among the diagnostic criteria or the predictors of ventricular arrhythmias (VA) and sudden death (SD). Computed tomography (CT) has excellent spatial resolution and allows a clear distinction between myocardium and fat; thus, it has great potential for the evaluation of myocardial scar in ARVC. The objective of this study is to evaluate the feasibility, and the diagnostic and prognostic value of semi-automated quantification of right ventricular (RV) fat replacement from CT images.

Regression of Cardiac Lymphoma With Chemotherapy.

A patient was admitted for chest pain with electrocardiographic changes, and cardiac magnetic resonance showed focal myocardial hypertrophy secondary to edema. Combined positron emission tomography and computed tomography corroborated foci of myocardial hypermetabolism, as well as multiple adenopathies consistent with lymphoma in the biopsy. Hypertrophy and edema regressed with chemotherapy.

Myocardial injury after major non-cardiac surgery evaluated with advanced cardiac imaging: a pilot study.

Background: Myocardial injury after non-cardiac surgery (MINS) is a frequent complication caused by cardiac and non-cardiac pathophysiological mechanisms, but often it is subclinical. MINS is associated with increased morbidity and mortality, justifying the need to its diagnose and the investigation of their causes for its potential prevention.

Methods: Prospective, observational, pilot study, aiming to detect MINS, its relationship with silent coronary artery disease and its effect on future adverse outcomes in patients undergoing major non-cardiac surgery and without postoperative signs or symptoms of myocardial ischemia.

Usefulness of Cardiac Computed Tomography in Coronary Risk Prediction: A Five-Year Follow-Up of the SPICA Study (Secure Prevention with Imaging of the Coronary Arteries).

Accurate identification of individuals at high coronary risk would reduce acute coronary syndrome incidence and morbi-mortality. We analyzed the effect on coronary risk prediction of adding coronary artery calcification (CAC) and Segment Involvement Score (SIS) to cardiovascular risk factors. This was a prospective cohort study of asymptomatic patients recruited between 2013-2017.

Coronary computed tomographic angiographic findings in asymptomatic patients with heterozygous familial hypercholesterolemia and null allele low-density lipoprotein receptor mutations.

Heterozygous familial hypercholesterolemia (HeFH) can be associated with early coronary artery disease (CAD) in asymptomatic patients. The objectives of the present study were to assess the prevalence and magnitude of subclinical CAD in patients with HeFH using coronary computed tomographic angiography (CCTA) and to determine the clinical and genetic profile of those at the greatest risk of CAD. The study included 50 consecutive patients with HeFH diagnosed according to the Dutch Lipid Clinic Network criteria and a control group of 70 healthy subjects.
