Ventricular assist devices (VADs) invigorated the management of patients with advanced heart failure, providing a lifeline for patients awaiting transplantation or requiring long-term circulatory support. This article reviews recent advances in VAD technologies, focusing on key areas of progress to overcome existing challenges and the potential for future applications. The reduction or possible elimination of infection-prone components and the evolution to transcutaneous energy transfer systems are two main research fields to reach a new quality of life category for VADs patients.

First-time NVE was compared with PVE, focusing on pathogens, risk factors, perioperative course, postoperative follow-up, including recurrent infection, as well as health-related quality of life (HRQOL). From 2007 to 2022, surgical intervention for AVE was necessary in 231 patients with 233 episodes of infective aortic valve endocarditis, i.

Importantly, atrial remodelling and atrial fibrillation are frequently observed in HFpEF. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have recently been shown to improve clinical outcomes in HFpEF, and post-hoc analyses suggest atrial anti-arrhythmic effects.

Computer-based systems could assist in the diagnostic process and potentially improve reproducibility. Here, we evaluated the feasibility of using deep learning in predicting the degree of cellular rejection from pathology slides as defined by the International Society for Heart and Lung Transplantation (ISHLT) grading system.

In this setting heart transplantation (HTX) is a treatment option for selected patients. We here present the results of post-transplantation outcomes in cardiac amyloidosis within the Eurotransplant area, investigating possible predictors of survival.

Our primary aim was to determine the influence of advanced age on short- and long-term outcome; the secondary aim was to analyze risk factors for impaired outcome.
Methods: Between January 2006 and June 2020, 645 patients underwent VA-ECMO implantation in our department.
Background: The outcome after veno-venous extracorporeal membrane oxygenation in elderly patients is supposed to be unsatisfactory. Our primary aim was to determine the influence of advanced age on short- and long-term outcomes; the secondary aim was to analyze risk factors for impaired outcomes.
Methods: Between January 2006 and June 2020, 755 patients received V-V ECMO support at our department.
Background: In reverse-mode, cardiac sodium-calcium exchanger (NCX) can increase the cytoplasmic Ca concentration in response to high intracellular Na levels, which may contribute to diastolic contractile dysfunction. Furthermore, increased spontaneous Ca release from intracellular stores can activate forward mode NCX. The resulting transient inward current causes delayed afterdepolarization (DAD)-dependent arrhythmias.

Methods: Data of 354 patients undergoing ECLS with one-, two, three-, and four organ failures were retrospectively analyzed.
Aims: Immunocompromised patients have been excluded from studies of SARS-CoV-2 messenger RNA vaccines. The immune response to vaccines against other infectious agents has been shown to be blunted in such patients. We aimed to analyse the humoral and cellular response to prime-boost vaccination with the BNT162b2 vaccine (Pfizer-BioNTech) in cardiothoracic transplant recipients.

Interestingly, an abnormal P-wave terminal force in electrocardiogram lead V (PTFV ) has been associated with atrial cardiomyopathy, but this association is poorly understood. We investigated PTFV as a marker for functional, electrical, and structural atrial remodelling.

Angiotensin-converting enzyme 2 (ACE2) has been identified as necessary cell entry point for SARS-CoV-2. Previous animal studies have demonstrated an increased ACE2 expression following treatment with either angiotensin-converting enzyme inhibitors (ACEi) or angiotensin II receptor blockers (ARB) that have led to a massive precariousness regarding the optimal cardiovascular therapy during this pandemic.

The impact of these scenarios on short- and long-term outcome are not well described.
Methods: Between March 2006 and December 2018, 261 patients received ECLS support after cardiac surgery.

Aims: Heart transplantation may represent a particular risk factor for severe coronavirus infectious disease 2019 (COVID-19) due to chronic immunosuppression and frequent comorbidities. We conducted a nation-wide survey of all heart transplant centers in Germany presenting the clinical characteristics of heart transplant recipients with COVID-19 during the first months of the pandemic in Germany.
Methods And Results: A multicenter survey of all heart transplant centers in Germany evaluating the current status of COVID-19 among adult heart transplant recipients was performed.
The use of minimized cardiopulmonary bypass support to reduce the side effects of extracorporeal circulation is still contradictorily discussed. This study compares perfusion operated by conventional (CCPB) and minimized (MCPB) cardiopulmonary bypass support during coronary artery bypass grafting (CABG). This study includes the data of 5164 patients treated at our department between 2004 and 2014.

During these interventions, iatrogenic cardiac perforation may ensue, which is a severe complication and requires immediate diagnostic assessment and treatment.
Methods: From March 2011 to April 2016, all patients referred to the Dept.
