Article Synopsis
- About 15% to 20% of long QT syndrome (LQTS) patients are genotype-negative (GEN-), leading to uncertainties in their risk and treatment compared to genotype-positive (GEN+) patients.
- The study evaluated 832 LQTS patients in Japan and Italy, finding that GEN- patients had more cardiac events and less family history of LQTS, especially in Japan.
- Despite some differences, the study concluded that the arrhythmic risk and clinical outcomes were similar for both GEN+ and GEN- patients, suggesting they should be managed the same way.
Pulmonary artery dissection is a rare and fatal disease. Diagnosis is mainly made during autopsy because most patients die suddenly due to pulmonary artery dissection in the pericardium resulting in pericardial tamponade. The optimum management is not clearly defined because of the paucity of cases in the literature.

Methods: LQT1/2/3 and genotype-negative patients without aborted cardiac arrest (ACA) before diagnosis or cardiac events (CEs) below age 1 were included in the study, focusing on an M-FACT score ≥2 (intermediate/high risk), either at presentation (static) or during follow-up (dynamic), previously associated with 40% risk of implantable cardioverter defibrillator (ICD) shocks within 4 years.
Common complications of coronavirus disease 2019 (COVID-19) related ARDS and ventilation are barotrauma-induced pneumothorax, pneumatocele and/or empyema. We analysed indications and results of video-assisted thoracoscopic surgery (VATS) in complicated COVID-19 patients. This is a retrospective single-institution study analysing a case series of patients treated by VATS for secondary spontaneous pneumothorax (SSP), pneumatocele and empyema complicating COVID-19, not responding to drainage in Lodi Maggiore Hospital between February 2020 and May 2021.

Objectives: The purpose of this study was to ascertain the risk of death, ventricular arrhythmias, recurrent myocarditis, and heart failure (main endpoint) in patients with AM and pathogenic or likely pathogenetic DGV.
Methods: In a retrospective international study from 23 hospitals, 97 patients were included: 36 with AM and DGV (DGV[+]), 25 with AM and negative gene testing (DGV[-]), and 36 with AM without genetics testing.
