Renal Function in Patients with or without a Left Ventricular Assist Device Implant During Listing for a Heart Transplant.

BACKGROUND Left ventricular assist device (LVAD) implantation may improve kidney function, but in patients awaiting heart transplantation, the long-term effects of LVAD implantation on renal function and subsequent clinical outcome are unclear. MATERIAL AND METHODS We analyzed data in patients with LVAD implants (n=139) and without LVAD implants (n=1038) who were listed for a heart transplant at our institution between 2000 and 2019. The primary endpoint was an impairment in renal function (decrease of creatinine-based estimated glomerular filtration rate [eGFR] by ≥30%) up to a maximum of 2 years after listing.

Changes in quality of life, cognition and functional status following catheter ablation of atrial fibrillation.

Objective: To investigate changes in quality of life (QoL), cognition and functional status according to arrhythmia recurrence after atrial fibrillation (AF) ablation.

Methods: We compared QoL, cognition and functional status in patients with recurrent atrial tachycardia (AT)/AF versus those without recurrent AT/AF in the AXAFA-AFNET 5 clinical trial. We also sought to identify factors associated with improvement in QoL and functional status following AF ablation by overall change scores with and without analysis of covariance (ANCOVA).

Long-Term Clinical Outcome in Elderly Patients Undergoing Mitral Valve Repair.

Background:  Long-term data on patients over 75 years undergoing mitral valve (MV) repair are scarce. At our high-volume institution, we, therefore, aimed to evaluate mortality, stroke risk, and reoperation rates in these patients.

Methods:  We investigated clinical outcomes in 372 patients undergoing MV repair with ( = 115) or without ( = 257) tricuspid valve repair.

Background: Previous TAVI investigations of first-generation devices demonstrated an early- to mid-term survival advantage in women compared with men.

Methods: SOURCE 3 (SAPIEN 3 Aortic Bioprosthesis European Outcome) is a post-approval, multicentre, observational registry.

Bicuspid Aortic Valve Morphology and Outcomes After Transcatheter Aortic Valve Replacement.

Background: Bicuspid aortic stenosis accounts for almost 50% of patients undergoing surgical aortic valve replacement in the younger patients. Expanding the indication of transcatheter aortic valve replacement (TAVR) toward lower-risk and younger populations will lead to increased use of TAVR for patients with bicuspid aortic valve (BAV) stenosis despite the exclusion of bicuspid anatomy in all pivotal clinical trials.

Objectives: This study sought to evaluate the association of BAV morphology and outcomes of TAVR with the new-generation devices.

Acute Hemoptysis Following Cryoballoon Pulmonary Vein Isolation: A Multicenter Study.

Objectives: This study sought to assess the incidence, procedural characteristics, contributing factors, and clinical outcome of cryoballoon-based pulmonary vein isolation (CB-PVI)-related hemoptysis in a multicenter study.

Background: Hemoptysis has been described as a rare complication of CB-PVI. However, the precise mechanism and the etiology of this complication are poorly characterized.

Significance of myeloperoxidase plasma levels as a predictor for cardiac resynchronization therapy response.

Objectives: This study aimed to determine if changes in myeloperoxidase (MPO) levels correlate with response to cardiac resynchronization therapy (CRT) and the potential role of MPO as a predictor of response to CRT.

Background: CRT is a well-established treatment option in chronic heart failure (CHF) with 50-80% of patients benefiting. Inflammation and oxidative stress play a key role in CHF pathophysiology.

Targeted metabolomic analysis of serum amino acids in the adult Fontan patient with a dominant left ventricle.

Growing interest lies in the assessment of the metabolic status of patients with a univentricular circulation after Fontan operation, especially in changes of amino acid metabolism. Using targeted metabolomic examinations, we investigated amino acid metabolism in a homogeneous adult Fontan-patient group with a dominant left ventricle, seeking biomarker patterns that might permit better understanding of Fontan pathophysiology and early detection of subtle ventricular or circulatory dysfunction. We compared serum amino acid levels (42 analytes; AbsoluteIDQ p180 kit, Biocrates Life Sciences, Innsbruck, Austria) in 20 adult Fontan patients with a dominant left ventricle and those in age- and sex-matched biventricular controls.

Targeted metabolomic analysis of serum phospholipid and acylcarnitine in the adult Fontan patient with a dominant left ventricle.

Background: Patients with a Fontan circulation have altered cholesterol and lipoprotein values. We analysed small organic molecules in extended phopsholipid and acylcarnitine metabolic pathways ('metabolomes') in adult Fontan patients with a dominant left ventricle, seeking differences between profiles in baseline and Fontan circulations.

Methods: In an observational matched cross-sectional study, we compared phosphatidylcholine (PC), sphingomyelin (SM), and acylcarnitine metabolomes (105 analytes; AbsoluteIDQ p180 kit (Biocrates Life Sciences AG, Innsbruck, Austria) in 20 adult Fontan patients having a dominant left ventricle with those in 20 age- and sex-matched healthy controls.

Objective: Residual paravalvular regurgitation (PVR) has been associated to adverse outcomes after transcatheter aortic valve replacement (TAVR). This study sought to evaluate the impact of device landing zone (DLZ) calcification on residual PVR after TAVR with different next-generation transcatheter heart valves.

Methods: 642 patients underwent TAVR with a SAPIEN 3 (S3; n=292), ACURATE (NEO; n=166), Evolut R (ER; n=132) or Lotus (n=52).

Intra-atrial Neomitral Ring Creation in the Presence of Severe Mitral Annulus Calcification.

Severe mitral annulus calcifications significantly hinder surgical repair and replacement of the dysfunctional mitral valve. Herein, we present a novel surgical technique where we created an intra-atrial neomitral ring using a vascular Dacron graft in which a prosthetic valve was implanted. This approach is a simple alternative technique that can be used when anatomic prosthetic valve implantation is not feasible.

Wave intensity analysis of maternal arterial stiffness: augmentation index and pulse wave velocity in pregnancies complicated by diabetes or hypertension.

Purpose: The aim of our study was to compare the maternal arterial stiffness in pregnant women with diabetic disease, hypertension and those with normal pregnancies.

Methods: A cross-sectional study was performed involving 65 pregnant women with diabetic disease (DD group), 26 pregnant women with hypertension (RR group) and 448 women with normal pregnancies (control group). The augmentation index (AIx) and the pulse wave velocity (PWV) of the right carotid artery were assessed using non-invasive sonographic wave intensity analysis.

Role of Vitamin D in Preventing and Treating Selected Extraskeletal Diseases-An Umbrella Review.

Evidence is accumulating that vitamin D may have beneficial effects on respiratory tract, autoimmune, neuro-degenerative, and mental diseases. The present umbrella review of systematic reviews (SRs) of cohort studies and randomised controlled trials (RCTs), plus single Mendelian randomisation studies aims to update current knowledge on the potential role of vitamin D in preventing and treating these extraskeletal diseases. Altogether, 73 SRs were identified.

Papillary Muscle Heads Focalization for Functional Mitral Valve Regurgitation.

Mitral valve annuloplasty has been the gold standard for treatment of functional mitral valve regurgitation. However, annuloplasty for functional mitral regurgitation may cause augmented posterior leaflet tethering, which results in functional anterior prolapse. Herein we added papillary muscle heads focalization for such patients.

Purpose: To characterize dark adaptation in patients with pseudoxanthoma elasticum, a systemic disease leading to calcification of elastic tissue including the Bruch membrane.

Methods: In this prospective case-control study, dark adaptation thresholds were measured using a Goldmann-Weekers dark adaptometer. Additional assessments included best-corrected visual acuity testing, contrast sensitivity, low luminance deficit, and vision-related quality of life.

The Therapeutic Effect of 1,8-Cineol on Pathogenic Bacteria Species Present in Chronic Rhinosinusitis.

Chronic rhinosinusitis (CRS) is marked by an inflamed mucosa of sinuses and is accompanied by a significantly reduced quality of live. Since no guidelines for the treatment of CRS are available, long lasting clinical histories with health care costs adding up to dozens of billion $ annually are caused by CRS. The progression of CRS is often induced by bacterial infections and/or a shift in microbiome as well as biofilm formation.

Influence of maternal HIV infection on fetal thymus size.

Objective To reveal the effect of a maternal human immunodeficiency virus (HIV) infection on the fetal thymus size. Methods The sonographic fetal thymus size was measured retrospectively in 105 pregnancies with maternal HIV infection and in 615 uncomplicated singleton pregnancies. The anteroposterior thymic and the intrathoracic mediastinal diameter were determined in the three-vessel view and their quotient, the thymic-thoracic ratio (TT ratio), was calculated.

The Mechanistic Differences in HLA-Associated Carbamazepine Hypersensitivity.

Drug hypersensitivity reactions that resemble acute immune reactions are linked to certain human leucocyte antigen (HLA) alleles. Severe and life-threatening Stevens Johnson Syndrome and Toxic Epidermal Necrolysis following treatment with the antiepileptic and psychotropic drug Carbamazepine are associated with HLA-B*15:02; whereas carriers of HLA-A*31:01 develop milder symptoms. It is not understood how these immunogenic differences emerge genotype-specific.

Procedure related risk of premature delivery and fetal growth reduction following amniocentesis, transcervical and transabdominal chorionic villus sampling: a retrospective study.

Background The aim of this study was to compare transabdominal and transcervical chorionic villus sampling (CVS) as well as amniocentesis (AC) with respect to their rates of premature delivery and fetal growth restriction. Methods We retrospectively evaluated the mentioned procedures of invasive prenatal testing performed in a single center between 2001 and 2016. Seven hundred and ninety-nine cases of AC and 719 cases of CVS were included, of which 400 were performed transvaginally.

Prevention of ventricular fibrillation through de-networking of the Purkinje system: Proof-of-Concept Paper on the Substrate Modification of the Purkinje Network.

Introduction: Sudden cardiac death from ventricular fibrillation (VF) remains a major health problem worldwide. Currently, there are limited treatment options available to patients who suffer from episodes of VF. Because Purkinje fibers have been implicated as a source of initiation of VF, we are presenting the first paper of a series highlighting the promising results of substrate modulation through "De-Networking" of the Purkinje system preventing VF in patients without an alternative ablation strategy.

Left ventricular mass estimation by real-time 3D echocardiography favourably competes with CMR in congenital left ventricular disease.

Assessment of left ventricular mass (LVM) is important in the evaluation of patients with congenital heart disease (CHD) and cardiac magnetic resonance imaging (CMR) is the gold standard. Recent software allows LVM calculation by real-time 3-dimensional echocardiography (RT3DE). We investigated the impact of different software analysis tools on LVM determination by CMR or RT3DE in a cohort of patients with heterogeneous left ventricular (LV) disease.
