The ScREEN score (Sex category, Renal function, ECG/QRS width, Ejection fraction and NYHA class) is composed of widely validated, easy to obtain predictors of CRT response, and predicts CRT response and overall mortality. It should be helpful in facilitating early consideration of alternative therapies for predicted non-responders to CRT therapy.

Pericardial inflammation is a recognised feature of coronavirus disease (COVID-19). The authors herein present the case of a female with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection who developed a large and life-threatening pericardial effusion over a few days following the onset of pericarditis, despite prompt commencement of treatment. This was successfully drained, and she was discharged in stable condition on oral nonsteroidal anti-inflammatory drugs and colchicine.At 6-week follow-up she had made a full recovery, and repeat echocardiography demonstrated no recurrence of effusion or evidence of constrictive physiology.
