Myocardial Blood Flow Quantified Using Stress Cardiac Magnetic Resonance After Mild COVID-19 Infection.

Background: Severe COVID-19 infection is known to alter myocardial perfusion through its effects on the endothelium and microvasculature. However, the majority of patients with COVID-19 infection experience only mild symptoms, and it is unknown if their myocardial perfusion is altered after infection.

Objectives: The authors aimed to determine if there are abnormalities in myocardial blood flow (MBF), as measured by stress cardiac magnetic resonance (CMR), in individuals after a mild COVID-19 infection.

Anomalous right coronary artery from the main pulmonary artery (ARCAPA): Incidental finding in an asymptomatic septuagenarian.

Anomalous right coronary artery (RCA) from the main pulmonary artery (ARCAPA) is a rare finding. Clinical presentations range from asymptomatic to sudden death. We present the case of ARCAPA in a septuagenarian initially suspected on a screening chest computed tomography (CT) and later confirmed on cardiac CT.

Quantitative Analysis of Contrast-enhanced Mammography for Risk Stratification of Benign Versus Malignant Disease and Molecular Subtype.

Objective: To assess quantitative enhancement of benign, high-risk, and malignant lesions and differences in molecular subtype and grade of malignant lesions on contrast-enhanced mammography (CEM).

Methods: This IRB-approved retrospective study included women who underwent CEM for diagnostic work-up of a breast lesion between 2014 and 2020. Inclusion criteria were women who had diagnostic work-up with CEM and had BI-RADS 1 or 2 with one year follow-up, BI-RADS 3 with tissue diagnosis or stability for 2 years, or BI-RADS 4 or 5 with tissue diagnosis.

Defying the Odds of Sudden Cardiac Death in Hypertrophic Cardiomyopathy.

We report an unusual case of a patient with hypertrophic obstructive cardiomyopathy, anomalous aortic origin of a coronary artery, obesity hypoventilation syndrome, and acquired long QT syndrome who was able to defy the odds of sudden cardiac death in the rarest of circumstances. ().

Heterogeneity of treatment effect in SPRINT by age and baseline comorbidities: The greatest impact of intensive blood pressure treatment is observed among younger patients without CKD or CVD and in older patients with CKD or CVD.

The Systolic Blood Pressure Intervention Trial (SPRINT), a large randomized controlled trial funded by the National Institutes of Health, randomized 9361 patients with hypertension over 50 years of age and at least one cardiovascular risk factor to intensive (SBP < 120 mm Hg) or standard (SBP < 140 mm Hg) blood pressure treatment. The trial found a significant reduction in primary cardiovascular and mortality outcomes in the intensive treatment group. We performed an IRB-approved post hoc analysis of the SPRINT trial data, recently made available through the NEJM SPRINT Data Analysis Challenge.

Improved dark blood late gadolinium enhancement (DB-LGE) imaging using an optimized joint inversion preparation and T magnetization preparation.

Purpose: To develop a dark blood-late gadolinium enhancement (DB-LGE) sequence that improves scar-blood contrast and delineation of scar region.

Methods: The DB-LGE sequence uses an inversion pulse followed by T magnetization preparation to suppress blood and normal myocardium. Time delays inserted after preparation pulses and T -magnetization-prep duration are used to adjust tissue contrast.

Reproducibility of myocardial T and T relaxation time measurement using slice-interleaved T and T mapping sequences.

Purpose: To assess measurement reproducibility and image quality of myocardial T and T maps using free-breathing slice-interleaved T and T mapping sequences at 1.5 Tesla (T).

Materials And Methods: Eleven healthy subjects (33 ± 16 years; 6 males) underwent a slice-interleaved T and T mapping test/retest cardiac MR study at 1.
