CMR Imaging 6 Months After Myocarditis Associated with the BNT162b2 mRNA COVID-19 Vaccine.

Temporal association between BNT162b2 mRNA COVID-19 vaccine and myocarditis (PCVM) has been reported. We herein present early and 6-month clinical follow-up and cardiac magnetic resonance imaging (CMR) of patients with PVCM. A retrospective collection of data from 15 patients with PCVM and abnormal CMR was performed.

Characterizing the differences between multisystem inflammatory syndrome in children and Kawasaki disease.

To characterize the new SARS-Co-V-2 related multisystem inflammatory syndrome in children (MIS-C) among Israeli children and to compare it with Kawasaki disease (KD). We compared, in two medical centers, the clinical and laboratory characteristics of MIS-C, KD and an intermediate group, which met the case definitions of both conditions. MIS-C patients were older, were more likely to be hypotensive, to have significant gastrointestinal symptoms, lymphopenia and thrombocytopenia and to have non-coronary abnormal findings in their echocardiogram.

Inefficient Ventriculoarterial Coupling in Fontan Patients: A Cardiac Magnetic Resonance Study.

The ventriculoarterial coupling (VAC) ratio, the ratio of arterial elastance (Ea) to ventricular end-systolic elastance (Ees), reflects cardiovascular efficiency. Little is known about this ratio in patients who have undergone the Fontan procedure. Our aim was to assess the VAC ratio in a cohort of Fontan patients using a cardiac magnetic resonance (CMR) method, and to examine its relation to outcomes.

Cardiac Findings in the Fetus with Cerebral Arteriovenous Malformation Are Associated with Adverse Outcome.

Objectives: To assess cardiac sequelae of fetal cerebral arteriovenous malformations (CAVMs) and evaluate any association with outcomes.

Methods: We retrospectively analyzed cardiac structure and function in fetuses with CAVMs who underwent fetal echocardiography (October 1999 to August 2015, n = 11), and compared them with normal controls.

Results: The median gestational age was 36 weeks (range 18-38).
