Cardiac Magnetic Resonance Imaging in Diagnostics and Cardiovascular Risk Assessment.

Cardiac magnetic resonance (CMR) allows for analysis of cardiac function and myocardial tissue characterization. Increased left ventricular mass (LVM) is an independent predictor of cardiovascular events; however, the diagnosis of left ventricular hypertrophy and its prognostic value strongly depend on the LVM indexation method. Evaluation of the quantity and distribution of late gadolinium enhancement assists in clinical decisions on diagnosis, cardiovascular assessment, and interventions, including the placement of cardiac implantable electronic devices and the choice of an optimal procedural approach.

Distinguishing hypertensive cardiomyopathy from cardiac amyloidosis in hypertensive patients with heart failure: a CMR study with histological confirmation.

Purpose: Differentiation of the cause of left ventricular hypertrophy (LVH) is challenging in cases with co-existing hypertension. CMR offers assessment of diffuse myocardial abnormalities via T1 mapping with extracellular volume fraction (ECV) and macroscopic fibrosis via late gadolinium enhancement imaging (LGE). The goal of the study was to understand if CMR parameters can differentiate hypertensive cardiomyopathy (HC) from cardiac amyloidosis (CA) in patients with hypertension and heart failure, using endomyocardial biopsy (EMB) as the gold standard.

Obstetric Cardiac Arrest: A Case Report.

Cardiac arrest during pregnancy does not occur infrequently and is influenced by obstetric and non-obstetric factors. The patient described in this case report is a pregnant woman who suffered a leg injury that required urgent surgical repair. Moments prior to that procedure, the fetus experienced extreme bradycardia on fetal heart tone monitoring.

The utility of the dilute prothrombin time in the interpretation of antiphospholipid syndrome testing.

Objectives: To evaluate the utility of the dilute prothrombin time (DPT) in diagnosing antiphospholipid syndrome (APS), alone and when paired with the dilute Russell viper venom time (DRVVT).

Methods: Dilute prothrombin time and DRVVT testing was performed on plasma samples spiked with apixaban or rivaroxaban, or depleted of vitamin K-dependent clotting factors. A retrospective analysis of all functional APS testing results over a 44-month period at the University of Chicago Medical Center was performed.

Prominent crista terminalis mimicking a right atrial mass: a systematic literature review and meta-analysis.

The crista terminalis is an anatomical structure localized on the posterolateral wall of the right atrium (RA). We performed a systematic review of the literature and meta-analysis concerning cases of unusual prominent crista terminalis mimicking RA mass. Moreover, we described the differential diagnosis of cardiac masses with the use of echocardiography, computed tomography, and cardiac magnetic resonance (CMR).
