Is Screening First-Degree Relatives of Cardiomyopathy Patients Worthwhile?
An observational study of screening first-degree relatives of patients with dilated cardiomyopathy revealed 14% will show either dilated left ventricles, low left ventricular function, or both. These findings are more common if the relatives have been diagnosed with hypertension or are obese, but their frequency is not altered by sex or race.

Unexpected Low Voltage on an ECG
A registry study of hypertrophic cardiomyopathy (HCM) patients and elite athletes in Italy revealed low voltage on ECG is not uncommon in HCM and may be a marker for more left ventricular scarring on cardiac imaging — and a poor prognosis.

Outcomes of COVID-19-Associated Acute Myocarditis
In a review of COVID-19-associated acute myocarditis, investigators learned it is a rare complication that can occur without concomitant pneumonia, and frequently presents as cardiogenic shock. With supportive therapy, the short-term mortality rate is low.

Significance of Flail Mitral Leaflet and Wall-Impinging Regurgitant Flow
Using cardiac MRI as a gold standard, the presence of a flail mitral leaflet or a wall-impinging mitral regurgitant jet on transthoracic echocardiography were associated with severe mitral regurgitation, but not diagnostic of it.
