Whole-Body Perfusion in Neonates and Infants Undergoing Aortic Arch Surgery-Working Towards the New Standard.

Neonatal aortic arch surgery remains one of the most challenging procedures in congenital cardiac surgery. In recent years, there has been a trend away from selective cerebral perfusion (SCP) and arrest of body circulation towards whole-body perfusion (WBP), a combination of SCP and lower-body perfusion (LBP), to facilitate arch surgery and preserve organ function. Retrospective, single-centre analysis was conducted of patients under one year of age undergoing aortic arch surgery from January 2014 until December 2022.

Nine Years of Continuous Flow LVAD (HeartMate 3): Survival and LVAD-Related Complications before and after Hospital Discharge.

Background: End-stage heart failure is associated with high mortality. Recent developments such as the left ventricular assist device (LVAD) have improved patient outcomes. The HeartMate 3 LVAD is a novel centrifugal pump that was developed to provide hemodynamic support in heart failure patients, either as a bridge-to-transplant (BTT), myocardial recovery, or destination therapy (DT).

Surgical Outcomes in Octogenarians with Heart Failure and Reduced Ejection Fraction following Isolated Coronary Artery Bypass Grafting-A Propensity Score Matched Analysis.

The demographic shift towards an aging population necessitates a reevaluation of surgical interventions like coronary artery bypass grafting (CABG) in octogenarians. This study aims to elucidate the outcomes of CABG in octogenarians with heart failure and reduced ejection fraction (HFrEF), a group traditionally considered at high risk for such procedures. Conducted across four academic hospitals in Germany from 2017 to 2023, this retrospective multicenter study assessed 100 patients (50 octogenarians ≥80 years and 50 non-octogenarians <80 years) with HFrEF undergoing isolated CABG.

Unraveling the Predictors for Delirium and ICU Stay Duration in Patients with Heart Failure and Reduced Ejection Fraction (HFrEF) Undergoing Coronary Artery Bypass Grafting-A Multicentric Analysis.

This study assesses predictors for postoperative delirium (POD) and ICU stay durations in HFrEF patients undergoing CABG, focusing on ONCAB versus OPCAB surgical methods. In cardiac surgery, especially CABG, POD significantly impacts patient recovery and healthcare resource utilization. With varying incidences based on surgical techniques, this study provides an in-depth analysis of POD in the context of HFrEF patients, a group particularly susceptible to this complication.

Influence of Obesity on Short-Term Surgical Outcomes in HFrEF Patients Undergoing CABG: A Retrospective Multicenter Study.

: This retrospective multicenter study investigates the impact of obesity on short-term surgical outcomes in patients with heart failure and reduced ejection fraction (HFrEF) undergoing coronary artery bypass grafting (CABG). Given the rising global prevalence of obesity and its known cardiovascular implications, understanding its specific effects in high-risk groups like HFrEF patients is crucial. : The study analyzed data from 574 patients undergoing CABG across four German university hospitals from 2017 to 2023.

Gender-Related Discrepancies in Short-Term Outcomes in Patients Undergoing Off-Pump Coronary Artery Bypass Grafting Surgery.

The sex differences in patients undergoing off-pump coronary artery bypass grafting (OPCAB) surgery are still unclear. Our aim was to investigate the impact of gender on short-term outcomes in males and females after off-pump bypass procedures. Our research was designed as a double-center retrospective analysis.

Consequences of Obesity on Short-Term Outcomes in Patients Who Underwent Off-Pump Coronary Artery Bypass Grafting Surgery.

The correlation between off-pump coronary artery bypass (OPCAB) surgery and obesity-related outcomes is still uncertain. The aim of our study was to analyse the pre-, intra-, and postoperative short-term outcomes between obese and non-obese patients after off-pump bypass surgery. We performed a retrospective analysis from January 2017 until November 2022, including a total of 332 (non-obese ( = 193) and obese ( = 139)) patients who underwent an OPCAB procedure due to coronary artery disease (CAD).

Short-Term Outcomes and Risk Factors of In-Hospital Mortality in Patients Suffering Acute Mesenteric Ischemia after Cardiac Surgery: Role of Opioids and Lactic Acid.

Acute mesenteric ischemia (AMI) is associated with poor clinical results after cardiac surgery. The aim of this study was to analyse the influence of AMI on short-term outcomes and all relevant risk factors of in-hospital mortality after cardiac surgery. Moreover, we aimed to investigate the role of opioids and lactic acid in the detection and prevention of AMI.

Risk factors associated with in-hospital mortality for patients with ECLS due to postcardiotomy cardiogenic shock after isolated coronary surgery.

Objectives: Extracorporeal membrane oxygenation or extracorporeal life support (ECLS) in patients after cardiac surgery and postcardiotomy cardiogenic shock (PCS) is known to be associated with high mortality. Especially in patients after coronary artery bypass grafting (CABG) and PCS, ECLS is frequently established. The aim of this analysis was to evaluate factors associated with in-hospital mortality in patients treated with ECLS due to PCS after CABG.

Multiple Grafting with Single Left Internal Mammary Artery as T-Graft with Itself.

Background: Revascularization strategies might be limited in patients with lack of sufficient bypass graft material and increased risk of wound healing disturbances. In this regard, we present first results of patients treated with left internal mammary artery (LIMA) as T-graft with itself due to left-sided double-vessel disease, elevated risk of wound healing infection, and lack of graft material.

Methods: Eighteen patients were retrospectively analyzed in this study.

Prognostic implications of psoas muscle area in patients undergoing transcatheter aortic valve implantation.

Objectives: This study sought to assess the incremental prognostic value of the psoas muscle area in patients scheduled for transcatheter aortic valve implantation (TAVI).

Methods: A total of 1076 consecutive patients undergoing TAVI at 2 centres between 2010 and 2017 were prospectively included in this study. Computed tomography-derived cross-sectional area of the psoas muscle was measured at the superior border of the third (L3) and fourth (L4) lumbar vertebra and indexed to body surface area (PMAi) as well as stratified into tertiles.

Minimally Invasive versus Conventional LVAD-Implantation-An Analysis of the Literature.

This review aims to provide an overview on recent data to evaluate minimally invasive (MVAD) and conventional (CVAD) left ventricular assist device (LVAD) implantation. A comprehensive literature search of PubMed, Cochrane Library, and ClinicalTrials.gov was conducted up to April 2017.

Incidence, predictors and clinical outcomes of residual stenosis after aortic valve-in-valve.

Objective: We aimed to analyse the incidence of prosthesis-patient mismatch (PPM) and elevated gradients after aortic valve in valve (ViV), and to evaluate predictors and associations with clinical outcomes of this adverse event.

Methods: A total of 910 aortic ViV patients were investigated. Elevated residual gradients were defined as ≥20 mm Hg.

EuroSCORE II and the STS score are more accurate in transapical than in transfemoral transcatheter aortic valve implantation.

Objectives: The European System for Cardiac Operative Risk Evaluation II (EuroSCORE II) and the Society of Thoracic Surgeons (STS) score are currently used to estimate periprocedural risk of death in patients undergoing transcatheter aortic valve implantation (TAVI). However, data regarding the predictive ability and usefulness of these scores for TAVI are controversial, especially for different access sites.

Methods: Between 2008 and 2016, 1192 consecutive patients undergoing TAVI [transfemoral (TF): n = 607 (51%); transapical (TA): n = 585 (49%)] at 2 centres were included.

Transapical aortic valve implantation in patients with pre-existing mitral valve prostheses: a case report.

Background: Transcatheter aortic valve implantation (TAVI) has proven to be a valid option for patients with severe aortic stenosis who are at high perioperative risk, particularly in patients with previous cardiac surgery. Several patients with previous mitral valve surgery were reported to have been successfully treated with TAVI.

Case Presentation: Two patients, one with mechanical and one with biological mitral valve prosthesis, presented with symptomatic severe aortic stenosis.

Expanding Surgical Opportunities: Endoscopic Harvesting of the Vena Saphena Parva in Supine Position.

The small saphenous vein (SSV) has proved to be a valid graft option for coronary artery bypass grafting (CABG), if other grafts are absent or unsuitable. Beside the described open technique we herein present our approach to endoscopic harvesting in supine position in seven patients. Harvesting was successful in six patients.
