Arrhythmias and Clinical Outcomes in a Swiss Multicenter Cohort of Patients With Dextro-Transposition of the Great Arteries and Atrial Switch.

Background Data on the incidence of arrhythmias, associated cardiac interventions, and outcome in patients with dextro-transposition of the great arteries and atrial switch are scarce. Methods and Results In this multicenter analysis, we included adult patients with dextro-transposition of the great arteries and atrial switch regularly followed up at 3 Swiss tertiary care hospitals. The primary outcome was a composite of left ventricular assist device, heart transplantation, and death.

Decongestion improving right heart function ameliorates prognosis after an acute heart failure episode.

Background: The prognostic role of decongestion-related change of cardiac morphology and in particular right heart function has not been investigated comprehensively in AHF patients.

Methods And Results: This prospective observational single-centre study included consecutive patients hospitalized for treatment of AHF with reduced, mildly-reduced or preserved left ventricular ejection fraction (LVEF). Comprehensive transthoracic echocardiography at admission and discharge assessed decongestion-related change of cardiac function and morphology.

[Cardiology].

Significant advances have been made in 2021 in the areas of interventional cardiology, heart failure, cardiac imaging, electrophysiology and congenital heart disease. In addition to improving the screening, diagnosis and management of many heart diseases, these advances will change our daily practice. Moreover, the European Society of Cardiology has updated its guidelines on heart failure, valve disease, cardiac pacing and cardiovascular disease prevention.

Has the profile of heart transplantation recipients changed within the last three decades?

Background: Heart transplantation remains the most durable treatment for patients with end-stage heart failure refractory to medical treatment. Central elements of the listing criteria for heart transplantation have remained largely unchanged in the last three decades whereas treatment of heart failure has significantly increased survival and reduced disease-related symptoms. It remains unknown whether the improvement of heart failure therapy changed the profile of heart transplantation candidates or affected post-transplant survival.

Complement blockade with eculizumab to treat acute symptomatic humoral rejection after heart transplantation.

Antibody-mediated rejection (AMR) is a major barrier preventing successful discordant organ xenotransplantation, but it also occurs in allotransplantation due to anti-HLA antibodies. Symptomatic acute AMR is rare after heart allograft but carries a high risk of mortality, especially >1 year after transplant. As complement activation may play a major role in mediating tissue injury in acute AMR, drugs blocking the terminal complement cascade like eculizumab may be useful, particularly since "standards of care" like plasmapheresis are not based on strong evidence.

[Paradigm shift in the treatment of atrial fibrillation. The importance of risk factor management].

The prevalence of atrial fibrillation (AF) is constantly rising. Different studies have underlined the correlation between AF and modifiable risk factors such as obesity, obstructive sleep apnea, hypertension and sedentary lifestyle. Treatment of these comorbidities could significantly reduce the AF burden and the recurrence rate after cardioversion or ablation.
