Background: There is marked variability in device-related (DR) infection frequencies across HeartMate 3 (HM3) centers. The goal is to correlate center driveline (DL) management and infection mitigation practices with DR-infection development, laying foundation for development of best practice recommendations for one facet of HM3 patient care.

Methods: Coordinators at 30 HM3 centers were surveyed about center practices for infection prophylaxis, intraoperative DL placement and postoperative care, and infection mitigation.

The 15th Annual Report from The Society of Thoracic Surgeons Interagency Registry for Mechanically Assisted Circulatory Support includes 29,634 continuous-flow left ventricular assist devices from the 10-year period between 2014 and 2024. The outcomes reported here demonstrate continued improved survival in the current era of fully magnetically levitated devices, with a significantly higher 1-year (85.7% vs 78.

There is an evolving role for guideline-directed medical therapy (GDMT) in managing heart failure with reduced ejection fraction after cardiac surgery. GDMT is based on the use of pharmacologic agents from each of 4 distinct drug classes, also known as the 4 pillars of heart failure therapy: β-blockers, renin-angiotensin system inhibitors, often paired with neprilysin inhibitors, mineralocorticoid receptor antagonists, and sodium-glucose cotransporter-2 inhibitors. Despite the demonstrated benefits of GDMT in reducing mortality and hospitalization rates in the nonsurgical literature, there is conspicuous underuse of GDMT after cardiac surgery.

Background: The objective of this study was to examine insurance-based disparities in mortality, nonhome discharges, and extracorporeal membrane oxygenation utilization in patients hospitalized with COVID-19.

Methods: Using a national database of U.S.

The 14th Annual Report from The Society of Thoracic Surgeons (STS) Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs) describes outcomes of 27,493 patients with a continuous-flow left ventricular assist device (LVAD) from the past decade (2013-2022). In 2022, 2517 primary LVADs were implanted, of which 2512 (99.8%) were fully magnetically levitated (Mag-Lev) devices.

Objective: Smaller body surface area (BSA) frequently precludes patients from left ventricular assist device (LVAD) therapy. We sought to investigate the clinical outcomes in patients with small BSA undergoing less invasive LVAD implantation.

Methods: We conducted a retrospective review of 216 patients implanted with HeartMate 3 LVAD (Abbott, Chicago, IL) via less invasive surgery at our institution.

Article Synopsis
  • The study focuses on the use of Left Ventricular Assist Devices (LVAD) in advanced heart failure patients, particularly those with a history of ventricular tachyarrhythmia (VTA), and aims to improve outcomes through a new intra-operative ablation protocol.
  • Researchers designed a randomized clinical trial involving 100 LVAD candidates, comparing those receiving intra-operative VTA ablation against those receiving standard medical management.
  • The trial will track various outcomes for an average of 18 months post-surgery, assessing VTA recurrence, adverse events, right heart function, healthcare utilization, and quality of life.

Objectives: The objective of this single-center, pilot, prospective, and historical control study is to evaluate safety and feasibility outcomes associated with left atrial appendage exclusion (LAAE) concomitant with left ventricular assist device (LVAD) implantation via less invasive surgery (LIS) as a stroke prevention strategy.

Methods: A predefined number of 30 eligible subjects scheduled for LIS LVAD with LAAE were enrolled in the prospective arm between January 2020 and February 2021. Eligible retrospective LIS LVAD patients without LAAE were propensity-matched in a 1:1 ratio with the prospective arm subjects.

Article Synopsis
  • The current standard of care for patients on venoarterial-extracorporeal membrane oxygenation (VA-ECMO) involves systemic anticoagulation, but this study suggests that not using anticoagulants may reduce complications.
  • A review of 203 patients indicated that those not receiving anticoagulation had significantly lower overall complication rates (57% versus 76%) and did not experience higher rates of thrombosis compared to those who were anticoagulated.
  • The non-anticoagulated group also required fewer blood transfusions and showed no cases of heparin-induced thrombocytopenia (HIT), indicating that VA-ECMO can be safely managed without routine anticoagulation in certain cases.

Background: Left ventricular assist device (LVAD) therapy has been the standard of care for selected patients with advance heart failure. Even though considerable strides have been achieved with the introduction of the newest centrifugal pump, therapy is still burdened with significant perioperative complications. Smaller devices, along with improved techniques and instruments, have encouraged the adoption of minimally invasive cardiac surgery (MICS) techniques for LVAD implantation to improve perioperative outcomes.

Objective: Bentall procedures are traditionally performed through a median sternotomy. The right mini-thoracotomy approach is increasingly used in aortic valve replacement. This approach has been shown to have decreased blood loss and hospital length of stay compared with sternotomy.

Aortic root replacement is typically performed through a median sternotomy. The right anterior mini-thoracotomy approach has been shown to decrease hospital length of stay in aortic valve surgery when compared to sternotomy. This approach is rare in ascending aortic surgery due to technical challenges which include exposure and annular suture placement.

Objectives: There are various strategies in the use of temporary mechanical circulatory support following orthotopic heart transplant (OHT). We sought to examine the outcomes following different temporary mechanical circulatory support strategies for acute graft failure.

Methods: Patients who received an OHT between 2001 and 2015 at a single institution were retrospectively reviewed.

Background: Trials have demonstrated improvements in survival with adding paclitaxel (P) or topotecan (T) to cisplatin (C) for the treatment of advanced cervical cancer. We sought to evaluate the cost effectiveness of these regimens.

Methods: A decision model was developed based on Gynecologic Oncology Group (GOG) protocols 169 and 179.
