Growth Differentiation Factor 15 as a Marker for Chronic Ventricular Pacing.

Right ventricular pacing is an effective and safe treatment option for patients experiencing symptomatic bradycardia. However, some individuals may develop left ventricular dysfunction as a consequence. Growth differentiation factor 15 (GDF-15), which is not present in a healthy adult heart, is upregulated in cardiomyocytes in response to various stress stimuli.

Impact of genetic test interpretation on a missense variant in Cohen syndrome.

Introduction: Cohen syndrome (CS) is an early-onset pediatric neurodevelopmental disorder characterized by postnatal microcephaly and intellectual disability. An accurate diagnosis for individuals with CS is crucial, particularly for their caretakers and future prospects. CS is predominantly caused by rare homozygous or compound heterozygous pathogenic variants in the vacuolar protein sorting-associated 13B () gene, which disrupt protein translation and lead to a loss of function (LoF) of the encoded VPS13B protein.

Myeloperoxidase and N-terminal proatrial natriuretic peptide as predictors for atrial fibrillation recurrence in patients undergoing redo ablation.

Background: Atrial fibrillation (AF) is a progressively developing arrhythmia. Electroanatomic remodeling may play an important role, both in the development of the disease and in the perpetuation and thus in the recurrence of AF.

Objective: This study aimed to investigate potential biomarkers myeloperoxidase (MPO), N-terminal proatrial natriuretic peptide (NT-proANP), intercellular adhesion molecule-1, and matrix metalloproteinase-2 and their predictive value for AF recurrence in patients undergoing redo ablation.

Self-efficacy, social support and oral health-related quality of life in patients with kidney transplantation and under hemodialysis.

Background: Aim of this questionnaire-based cross-sectional study was to compare self-efficacy, social support, oral hygiene-related self-efficacy (OHRSE) and oral health-related quality of life (OHRQoL) between patients under chronic hemodialysis (HD) and patients after kidney transplantation (KTx) as well as a healthy comparison group (HC).

Methods: Patients under HD were recruited during their routine outpatient dialysis therapy, KTx patients during their maintenance appointment and HC patients during their regular dental check-up in the dental clinic. General self-efficacy, the OHRSE, social support (F-SozU-K14) and the OHRQoL (OHIP-G5) were assessed by specific validated questionnaires.

We performed a bibliometric analysis on tricuspid regurgitation with a focus on imaging techniques and treatment approaches and to identify scientific milestones and emerging research trends.

Impact of Physical Activity in Patients With Atrial Fibrillation Undergoing Catheter Ablation: The Multicenter Randomized BE-ACTION Trial.

Background: Arrhythmia recurrence after pulmonary vein isolation (PVI) is common. We conducted a multicenter, randomized trial to determine the impact of increased physical activity on atrial fibrillation recurrence after PVI.

Methods: From 2018 to 2020, we randomly assigned 200 patients with atrial fibrillation to the ACTION or NO-ACTION group in 4 different centers in the local country of Brandenburg, Germany.

Usability and accuracy of two different aortic annulus sizing software programs in patients undergoing transcatheter aortic valve replacement.

Background: Semi-automated software is essential for planning and prosthesis selection prior transcatheter aortic valve replacement (TAVR). Reliable data on the usability of software programs for planning a TAVR is missing. The aim of this study was to compare software programs 'Valve Assist 2' (GE Healthcare) and 3mensio 'Structural Heart' (Pie Medical Imaging) regarding usability and accuracy of prosthesis size selection in program-inexperienced users.

Palpitations in puerperium-a self-recorded smart watch ECG gives the hint to hormone-induced ventricular arrhythmia: case report.

Background: Gender-related aspects in cardiac arrhythmias have gained increasing attention, still the understanding of peripartum electrical disorders remains vague.

Case Summary: A 28-year-old woman developed palpitations and presyncopes during the post-partum period after her second pregnancy. Palpitations remained unclear until a self-recorded single-lead smartwatch ECG revealed a complete episode of a fast broad complex tachycardia (260 b.

Cluster analysis of volatile organic compounds - A pilot study in patients with severe acute decompensated heart failure.

Introduction: Acute decompensated heart failure (ADHF) is a global health problem and early detection of high-risk patients for effective treatment is important. Exhaled breath analysis and measurement of volatile organic compounds (VOCs) may be a fast and cost-effective non-invasive diagnostic and screening tool complementing measurement of cardiac biomarkers. Another technique to detect and characterize VOCs is the ion mobility spectrometry (IMS) not requiring vacuum or sample pretreatment.

Left atrial low-voltage areas, but not volume, predict the recurrence of atrial fibrillation in repeat ablation procedures.

Introduction: Left atrial (LA) low voltage areas (LVA) are a controversial target in atrial fibrillation ablation procedures. However, LVA and LA volume are good predictors of arrhythmia recurrence in ablation-naïve patients. Their predictive value in progressively diseased pre-ablated atria is uncertain.

Outcome and microbiological findings of patients with cardiac implantable electronic device infection.

Introduction: Infections associated with cardiac implantable electronic devices (CIEDs) are a multifactorial disease that leads to increased morbidity and mortality.

Objective: The aim was to analyze patient-, disease- and treatment-related characteristics including microbiological and bacterial spectrum according to survival status and to identify risk factors for 1- and 3-year mortality in patients with local and systemic CIED infection.

Methods: In a retrospective cohort study, we analyzed data from patients with CIED-related local or systemic infection undergoing successful transvenous lead extraction (TLE).

Soluble Suppression of Tumorigenicity 2 (sST2) in Patients with Predominantly Decompensated Right Heart Failure-A Prospective Observational Study.

Right heart failure is a major challenge in clinical practice. Soluble Suppression of Tumorigenicity-2 (sST2), a member of the interleukin-1-receptor family, may have clinical prognostic value. The aim of this study was to analyze whether sST2 correlates with signs of acute right heart decompensation.

App-based assessment of memory functions in patients after transfemoral aortic valve replacement.

Background: Transfemoral aortic valve replacement (TAVR) is the standard treatment for elderly patients with aortic valve stenosis. Although safe and well-established, there is a risk of intraprocedural hemodynamic instability and silent cerebral embolism, which can lead to a decline in neurocognitive function and dementia. In clinical practice, comprehensive cognitive testing is difficult to perform.

Care Bundle for Acute Kidney Injury in Cardiac Patients: A Cluster-Randomized Trial.

Detection and timely intervention of acute kidney injury (AKI) is a major challenge worldwide. Electronic alerts for AKI may improve process- and patient-related endpoints. The present study evaluated the efficacy of an AKI electronic alert system and care bundle.
