AIMS Due to bioprosthetic valve degeneration, aortic valve-in-valve (ViV) procedures are increasingly performed. There are no data on long-term outcomes after aortic ViV. Our aim was to perform a large-scale assessment of long-term survival and reintervention after aortic ViV. METHODS AND RESULTS A total of 1006 aortic ViV procedures performed more than 5 years ago [mean age 77.7 ± 9.7 years; 58.8% male; median STS-PROM score 7.3% (4.2-12.0)] were included in the analysis. Patients were treated ...

BACKGROUND The clinical profile of left ventricular assist device (LVAD) candidates is rapidly changing, with increasing proportion of patients in more stable clinical conditions. However, early postoperative right ventricular failure (eRVF) is still one of the cornerstones associated with increased mortality and the preoperative recognition of associated risk factors remains challenging. The aim of this study was to identify predictive parameters for eRVF after LVAD implantation in patients wit...

Objectives: Development of right ventricular failure (RVF) after left ventricular assist device (LVAD) implantation remains a leading cause of perioperative morbidity, end-organ dysfunction and mortality. The objective of this study was to investigate whether the etiology of HF (ischemic HF versus non-ischemic HF) affects the risk of RVF within admission for LVAD implantation and during long-term follow-up. Methods: Between January 2011 and June 27, 2018, 3536 patients were prospectively enrolle...

During aging, senescent cells accumulate in various tissues accompanied by decreased regenerative capacities of quiescent stem cells, resulting in deteriorated organ function and overall degeneration. In this regard, the adult human heart with a generally low regenerative potential is of extreme interest as a target for rejuvenating strategies with blood borne factors that might be able to activate endogenous stem cell populations. Here, we investigated for the first time the effects of human bl...

INTRODUCTION Heart transplantation is the desired therapy in end-stage heart failure (HF) and in patients with left-ventricular assist devices (LVAD) suffering from life-threatening complications on device. Comorbidities are frequent in end-stage HF and may refrain the patient from being listed for heart transplantation such as infections making surgery impossible. PRESENTATION OF CASE We report the first case of a patient with proven LVAD system infection who additionally suffers from a brain a...

: Assessing hemodynamics, especially central venous pressure (CVP), is essential in heart failure (HF). Right heart catheterization (RHC) is the gold-standard, but non-invasive methods are also needed. However, the role of 2-dimensional echocardiography (2DE) remains uncertain, and 3-dimensional echocardiography (3DE) is not always available. This study investigated standardized and breathing-corrected assessment of inferior vena cava (IVC) volume using echocardiography (2DE and 3DE) versus CVP ...

Abstract 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 neo-mitral 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. Major assets of this approach are evasion of extensive debridement, impl...

Purpose In patients supported by a ventricular assist device (VAD) major infections are a frequently reported adverse event with increased morbidity and mortality. The purpose of this study was to investigate the possible association of infections and cerebrovascular accidents (CVAs). Methods An analysis of the European Registry for Patients Assisted with Mechanical Circulatory Support (EUROMACS) was performed identifying all patients aged ≥18 years with a LVAD or BiVAD implantation. Infections ...

Purpose The aim of this study was to analyze short and long-term outcomes in patients who were treated with veno-arterial extracorporeal membrane oxygenation (vaECMO) for treatment of perioperative low-output-syndrome (LOS) and identify risk factors for in-hospital mortality. Methods All consecutive patients who received vaECMO during or after cardiac surgery at a high volume center between 01/2008 and 12/2017 were identified. This patient cohort was characterized and long-term survival (9 years...

PURPOSE There are still discordant data on the effect of concomitant cardiac procedures (CCPs) performed during left ventricular assist device (LVAD) implantation. METHODS By investigating on the European Registry for Patients with Mechanical Circulatory Support (EUROMACS) dataset, we identified 2760 patients (pts) who underwent continuous-flow (CF) long-term LVAD implantation. LVAD implantation was associated with a single CCP in 533 pts (19.3%). A propensity score (PS) matching (LVAD pts, n=48...
