TriGuard Embolic Protection Device in percutaneous cardiac interventions with intracavitary cardiac thrombosis: A case series.

Embolic cerebral protection devices are not routinely used in clinical practice during electrophysiological interventions. We report a case series of patients with intracardiac thrombosis undergoing a percutaneous left atrial appendage (LAA) closure and a ventricular tachycardia (VT) catheter ablation supported by TriGuard 3 Cerebral Embolic Protection Device.

Cardiac and arrhythmic complications in patients with COVID-19.

In December 2019, the world started to face a new pandemic situation, the severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2). Although coronavirus disease (COVID-19) clinical manifestations are mainly respiratory, major cardiac complications are being reported. Cardiac manifestations etiology seems to be multifactorial, comprising direct viral myocardial damage, hypoxia, hypotension, enhanced inflammatory status, ACE2-receptors downregulation, drug toxicity, endogenous catecholamine adrenergic status, among others. Studies evaluating patients with COVID-19 presenting cardiac injury markers show that it is associated with poorer outcomes, and arrhythmic events are not uncommon. Besides, drugs currently used to treat the COVID-19 are known to prolong the QT interval and can have a proarrhythmic propensity. This review focus on COVID-19 cardiac and arrhythmic manifestations and, in parallel, makes an appraisal of other virus epidemics as SARS-CoV, Middle East respiratory syndrome coronavirus, and H1N1 influenza.

Combined LASER and femoral approach to remove a previous failure of Riata lead extraction.

Transvenous extraction of Riata lead could be a challenging procedure due to insulation failure and conductor cables' externalization through the eroded outer insulation. In this case, a complete lead extraction was achieved through a combined LASER and femoral approach because of the massive conductors' externalization.
