In recent years, the use of transcatheter valve-in-valve implantation in the mitral position (TMVI) for the treatment of mitral valve pathology following ring or bioprosthetic implantation has emerged as a less invasive option in comparison to repeated mitral valve surgery (RMVS). We aimed to compare the early and mid-term results of these two strategies. We retrospectively analyzed all patients who underwent a mitral intervention in our institution between 2005 and 2022.

Background: Patients requiring coronary artery bypass grafting (CABG) are often loaded with antithrombotic drugs (AT) and are at an increased risk for perioperative bleeding complications. Active AT removal by a hemoadsorption cartridge integrated in the cardiopulmonary bypass circuit is increasingly used in this setting to reduce bleeding, and herein we describe the extension of this application in patients on AT undergoing off-pump coronary artery bypass (OPCAB).

Methods: Ten patients (80% male; mean age: 67.

Background And Aims: There is significant potential to streamline the clinical pathway for patients undergoing transcatheter aortic valve implantation (TAVI). The purpose of this study was to evaluate the effect of implementing BENCHMARK best practices on the efficiency and safety of TAVI in 28 sites in 7 European countries.

Methods: This was a study of patients with severe symptomatic aortic stenosis (AS) undergoing TAVI with balloon-expandable valves before and after implementation of BENCHMARK best practices.

Background: Deep sternal wound infection (DSWI) following open heart surgery is associated with excessive morbidity and mortality. Contemporary DSWI risk prediction models aim at identifying high-risk patients with varying complexity and performance characteristics. We aimed to optimize the DSWI risk factor set and to identify additional risk factors for early postoperative detection of patients prone to DSWI.

Background: predicting the 1-year survival of patients undergoing transcatheter aortic valve implantation (TAVI) is indispensable for managing safe early discharge strategies and resource optimization.

Methods: Routinely acquired data (134 variables) were used from 629 patients, who underwent transfemoral TAVI from 2012 up to 2018. Support vector machines, neuronal networks, random forests, nearest neighbour and Bayes models were used with new, previously unseen patients to predict 1-year mortality in TAVI patients.

Objectives: Aortic valve replacement with a sutureless prosthesis [sutureless aortic valve replacement (Su-AVR)] is an option for patients with severe aortic valve stenosis. However, data regarding long-term outcomes and prosthesis durability are still lacking.

Methods: All consecutive patients who successfully underwent Su-AVR with the Perceval valve in our centre between 2010 and 2020 were included in the analysis and followed prospectively with echocardiography.

: The hemoadsorption device CytoSorb (CytoSorbents Inc., Princeton, NJ, USA) has been shown to efficiently remove ticagrelor from whole blood in vitro. A promising clinical experience was made with the integration of the hemoadsorption cartridge on the cardiopulmonary bypass (CPB) circuit during cardiac surgery to reduce adverse events.

Background: Cardiac surgery in patients with infective endocarditis (IE) is still associated with high mortality and morbidity; an already present inflammation might further be aggravated due to a cardiopulmonary bypass-induced dysregulated immune response. Intraoperative hemoadsorption therapy may attenuate this septic response. Our objective was therefore to assess the efficacy of intraoperative hemoadsorption in active left-sided native- and prosthetic infective endocarditis.

Background: Occluding the left atrial appendage (LAA) during cardiac surgery reduces the risk of ischemic stroke; nonetheless, it is currently only softly recommended with "may be considered" by the current guidelines. We aimed to assess thromboembolic risk after LAA amputation in patients with atrial fibrillation (AF) and aortic stenosis undergoing biological aortic valve replacement (AVR) as primary cardiac surgery.

Methods: Two cohorts were generated retrospectively: patients with AF undergoing AVR alone or combined with revascularization either with LAA amputation or without.

Objectives: The aim of this study was to analyse the outcome of patients between 50 and 69 years of age undergoing biological or mechanical aortic valve replacement.

Methods: Data were collected from the German Aortic Valve Registry. Data were analysed regarding baseline characteristics and outcome parameters such as 5-year survival, stroke and reintervention.

Objectives: This study aims to improve the early detection of cardiac surgery-associated acute kidney injury using artificial intelligence-based algorithms.

Methods: Data from consecutive patients undergoing cardiac surgery between 2008 and 2018 in our institution served as the source for artificial intelligence-based modelling. Cardiac surgery-associated acute kidney injury was defined according to the Kidney Disease Improving Global Outcomes criteria.

Objectives: To assess the impact of prosthesis choice and aortic valve calcifications on the occurrence of conduction disturbances after transcatheter aortic valve implantation (TAVI).

Methods: We retrospectively analyzed the preoperative clinical characteristics, electrocardiograms, contrast-enhanced multidetector computed tomography scans and procedural strategies of patients who underwent TAVI in our center between January 2012 and June 2017. Quantification of calcium volume was performed for each aortic cusp above (aortic valve) and below (left ventricular outflow tract, LVOT) the basal plane.

Objectives: Postoperative atrial fibrillation (POAF) is a frequent complication following cardiac surgery. This study examined the safety and efficacy of the new system consisting of two bi-atrial temporary pacing and cardioversion electrodes, a ventricular electrode and the device (combined external pacemaker and cardioverter) for low-energy atrial cardioversion.

Methods: The temporary electrodes were placed on the left and right atrium during open heart surgery.

Leaflet durability and costs restrict contemporary trans-catheter aortic valve replacement (TAVR) largely to elderly patients in affluent countries. TAVR that are easily deployable, avoid secondary procedures and are also suitable for younger patients and non-calcific aortic regurgitation (AR) would significantly expand their global reach. Recognizing the reduced need for post-implantation pacemakers in balloon-expandable (BE) TAVR and the recent advances with potentially superior leaflet materials, a trans-catheter BE-system was developed that allows tactile, non-occlusive deployment without rapid pacing, direct attachment of both bioprosthetic and polymer leaflets onto a shape-stabilized scallop and anchorage achieved by plastic deformation even in the absence of calcification.

Objective: Sutureless aortic valves are an effective option for aortic valve replacement (AVR) showing non-inferiority to standard stented aortic valves for major cardiovascular and cerebral events at 1-year. We report the 1-year hemodynamic performance of the sutureless prostheses compared with standard aortic valves, assessed by a dedicated echocardiographic core lab.

Methods: Perceval Sutureless Implant vs.

Background: The vascular access in transcatheter aortic valve replacement (TAVR) was initially dominated by a surgical approach. Meanwhile, percutaneous closure systems became a well-established alternative. The aim of this study was to compare the clinical outcome between the two approaches.

Article Synopsis
  • The study aimed to assess how the COVID-19 pandemic affected urgent and elective thoracic and abdominal aortic surgeries between January-May 2020 and the same period in 2019.
  • Researchers found no significant change in the number of urgent procedures, but there was a notable 35% drop in elective surgeries during the pandemic, especially in countries like Italy.
  • Patients with acute conditions still sought treatment, indicating that while elective cases decreased, emergency cases were managed as per the guidelines, warranting further investigation into the long-term effects of delayed elective surgeries.

The HAART 300 (BioStable Science and Engineering, Austin, TX) is a rigid, elliptical device introduced to facilitate aortic valve repair providing annular stabilization in the setting of aortic regurgitation. Percutaneous strategies have been described for patients with dysfunctional biological prostheses or recurrence insufficiency after mitral ring annuloplasty. This report shows the feasibility of aortic valve-in-ring transcatheter aortic valve replacement (TAVR).
