Left ventricular assist device (LVAD) therapy improves survival and quality of life by mechanically unloading the left ventricle and maintaining hemodynamics in patients with end-stage heart failure. LVADs can also be lifesaving by maintaining hemodynamics during ventricular arrhythmia. Continuous-flow LVADs have become the preferred LVAD technology. As presented here, a continuous-flow LVAD successfully provided hemodynamic support to a patient in sustained ventricular fibrillation for over 12 hours when the internal defibrillator was unable to terminate the arrhythmia. This case demonstrates that continuous-flow LVADs can be lifesaving in the setting of otherwise certain hemodynamic collapse from sustained ventricular fibrillation.

Background: Women with heart failure with reduced ejection fraction (HFrEF) often experience worse clinical outcomes compared to men, including higher rates of mortality, hospitalization, and congestion. However, the effects of sacubitril/valsartan on these outcomes, as well as on ventricular tachyarrhythmias, have not been well studied in women with HFrEF.
Methods: This study included consecutive series of patients treated with sacubitril/valsartan at University Hospital Mannheim from 2016 to 2020.

Background: Charcot-Marie-Tooth is the most common inherited neuromuscular disorder. Rarely, it can be associated with heart failure and various arrhythmic disturbances. This case illustrates the challenges of making decisions to prevent sudden cardiac death in a patient with Charcot-Marie-Tooth disease.

Sympathoexcitation is a hallmark of heart failure, with sustained β-adrenergic receptor (βAR)-G protein signaling activation. βAR signaling is modulated by regulator of G protein signaling (RGS) proteins. Previously, we reported that Gα regulation by RGS2 or RGS5 is key to ventricular rhythm regulation, while the dual loss of both RGS proteins results in left ventricular (LV) dilatation and dysfunction.

Background: Desmoplakin (DSP) variants are associated with left-predominant or biventricular arrhythmogenic cardiomyopathy. Exercise promotes penetrance and sustained ventricular arrhythmias (VA) in right-sided arrhythmogenic right ventricular cardiomyopathy, but its effect is unknown in DSP variant carriers.
Objectives: To assess whether exercise is associated with clinical outcomes among individuals with a pathogenic or likely pathogenic (P/LP) DSP variant.

Background: Hypertrophic cardiomyopathy (HCM) needs careful differentiation from other cardiomyopathies. Current guidelines recommend genetic testing, but genetic data on differential diagnoses and their relation with clinical outcomes in HCM are still lacking. This study aimed to investigate the prevalence of genetic variants and the proportion of other cardiomyopathies in patients with suspected HCM in Korea and compare the outcomes of HCM according to the presence of sarcomere gene mutation.
