Standard Defibrillator Leads for Left Bundle Branch Area Pacing: First-in-Man Experience and Short-Term Follow-Up.

The authors report for the first time to their knowledge, implantation of a standard implantable cardioverter-defibrillator lead for permanent delivery of left bundle branch area pacing. Implantation was successful and safe in 11 of 12 patients, with adequate defibrillation testing, good electrical and electrocardiographic parameters, and uneventful device-related short-term follow-up.

[Bradyarrythmias in acute coronary syndromes].

In up to 30-40% of the cases acute coronary syndrome (ACS) is complicated by cardiac arrhythmias. The latter can be benign or malignant and mainly occur during the first 24 hours after myocardial infarction. Ischemia time being the key factor, arrythmias decreased dramatically since the implementation of accelerated reperfusion strategies.

[New perspectives in the diagnosis and treatment of heart failure with preserved ejection fraction (HFpEF)].

Heart failure with preserved ejection fraction (HFpEF), defined as ≥50 %, affects 1 to 3 % of the population and represents a diagnostic challenge. Clinical scores have been developed to facilitate the diagnosis of affected patients, who can now benefit from new treatments. Recent studies have shown a reduction in cardiovascular morbidity and mortality with sodium-glucose cotransporter-2 (SGLT-2) inhibitors in this population.

Current of injury amplitude during left bundle branch area pacing implantation: impact of filter settings, ventricular pacing, and lead type.

Aims: Monitoring current of injury (COI) during left bundle branch area pacing (LBBAP) implantation is useful to evaluate lead depth. Technical aspects for recording COI amplitude have not been well studied. Our aims were to evaluate the impact of high-pass filter settings on electrogram recordings during LBBAP implantation.

Procedural outcome and follow-up of stylet-driven leads compared with lumenless leads for left bundle branch area pacing.

Aims: Left bundle branch area pacing (LBBAP) is most often delivered using lumenless leads (LLLs), but may also be performed using stylet-driven leads (SDLs). There are limited reports on the comparison of these tools, mainly limited to reports describing initial operator experience or without detailed procedural data. Our aim was to perform an in-depth comparison of SDLs and LLLs for LBBAP at implantation and follow-up in a larger cohort of patients with experience that extends beyond that of the initial learning curve.

[Cardiac tumors in clinical practice].

Cardiac tumors are rare in clinical practice but remain an essential part of the fast-growing field of cardio-oncology. They can be detected incidentally and consist of primary tumors (benign or malignant) and of the more prevalent secondary tumors (metastasis). They form a heterogeneous group of pathologies presenting with a wide panel of clinical symptoms according to their location and size.

Coronavirus disease 2019-associated coronary endotheliitis and thrombotic microangiopathy causing cardiogenic shock: a case report.

Background: Coronavirus disease 2019 (COVID-19) primarily affects the respiratory tract but serious cardiovascular complications have been reported. Up to one-third of patients admitted to the intensive care unit may develop an acute myocardial injury, characterized by cardiac troponin elevation. However, the pathology underlying COVID-19-associated myocardial injury has rarely been reported.

Catastrophic Bone Cement Implantation Syndrome Treated with Venoarterial Extracorporeal Membrane Oxygenation: A Case Report.

• BCIS is a rare but serious complication of cemented bone surgeries. • The pathophysiology is suggested to be a pulmonary embolization of various particles. • Cardiopulmonary conditions, femur fracture, and old age are risk factors of BCIS.

[Myocarditis in 2020].

Myocarditis is an inflammatory disease of the myocardium caused by various etiologies with a dominance of viral infections and potential post-infectious autoimmunity. The clinical presentation ranges from chest pain to severe complications including cardiogenic shock, ventricular arrhythmias, and progression to dilated cardiomyopathy. The diagnostic approach is challenging and includes several investigations, such as an ECG, an echocardiography, troponin testing and the exclusion of coronary artery disease.

Leadless pacing using the transcatheter pacing system (Micra TPS) in the real world: initial Swiss experience from the Romandie region.

Aims: Leadless pacemakers are implanted in Switzerland since June 2015. Large worldwide registries have shown high implant success, low complication rates, and good electrical parameters up to 12 months' follow-up. However, data are scarce outside the investigational setting.
