Clinical significance of coronavirus disease 2019 in hospitalized patients with myocardial injury.
The clinical significance of Coronavirus disease 2019 (COVID-19) as an associate of myocardial injury is controversial. ⋯ Cardiac sequelae of COVID-19 typically manifest as Non-cardiac myocardial injury/Type 2MI in younger patients with less co-morbidity. Paradoxically, the admission duration and in-hospital mortality are increased.

Assessment of ventricular mechanical synchronization after left bundle branch pacing using 2-D speckle tracking echocardiography.
The left bundle branch pacing (LBBP) makes the ventricular depolarization closer to the physiological state and shortens QRS duration. The purpose of this study is to explore the ventricular systolic mechanical synchronization after LBBP in comparison with traditional right ventricular pacing (RVP) using two-dimensional strain echocardiography (2D-STE). ⋯ LBBP is able to provide a physiologic ventricular activation pattern, which results in ventricular mechanical contraction synchronization.

Meta AnalysisComparison of high-power short-duration and low-power long-duration radiofrequency ablation for treating atrial fibrillation: Systematic review and meta-analysis.
High power shorter duration (HPSD) ablation seen to increase efficacy and safety treating of atrial fibrillation (AF); however, comparative data between HPSD and low power longer duration (LPLD) ablation are limited. ⋯ HPSD was safe and efficient for treating AF. Compared with LPLD, HPSD was associated with advantages of procedural features, higher first-pass PVI and reducing recurrence of atrial arrhythmias. Moreover, major complications and ETI were similar between two groups.

ReviewCOVID-19, thromboembolic risk, and Virchow's triad: Lesson from the past.
COronavirus Infectious Disease which started in 2019 (COVID-19) usually presents with the signs and symptoms of pneumonia. However, a growing number of recent reports highlight the fact that the infection may be by far more than only a respiratory disease. There is evidence of an increased thromboembolic risk in COVID-19 patients, with a variety of manifestations in terms of ischemic stroke, deep vein thrombosis, acute pulmonary embolism, acute myocardial infarction, systemic arterial embolism, and placental thrombosis. ⋯ Many of the drugs proposed and currently undergoing evaluation for the treatment of COVID-19 have one or more of the Virchow's triad elements as a target. The three factors outlined by Virchow are still able to explain the venous and arterial hypercoagulable state in the dramatic COVID-19 setting. Nowadays, we have decidedly more sophisticated diagnostic tools than Virchow had, but many of the challenges that we are facing are the same as Virchow faced in the 19th century.

SARS-CoV-2, the cause of the COVID-19 pandemic has significantly impacted cardiovascular healthcare. Patients with pre-existing cardiovascular disease are at higher risk of morbidity and mortality. ⋯ The involvement of the RAAS system in viral entry makes it pertinent to consider the effects of medications that modulate the system. Comprehensive knowledge of peculiar cardiovascular manifestations of COVID-19 and the role of RAAS in the prognosis of COVID-19 disease is needed for optimal patient management.
