Turner syndrome is a rare chromosomal abnormality in women that is caused by a partial or complete loss of one X chromosome and is often associated with a spectrum of congenital cardiac abnormalities, including cardiac shunts. A 27-year-old woman with Turner syndrome was also found to have right ventricular dilation, partial anomalous pulmonary venous return, and possible atrial septal defect. She was scheduled for elective surgical repair.

Methods: A retrospective, observational analysis of consecutive patients requiring VV ECMO for COVID-19-associated respiratory failure was performed at a single institution between March 2020 and January 2022. Data were collected from the medical records.
Cessation of continuous analgesia and sedation in patients with acute respiratory distress syndrome (ARDS) receiving venovenous (VV) extracorporeal membrane oxygenation (ECMO) facilitates early extubation, family, patient and provider engagement, and mobility. Outcomes associated with an awake ECMO strategy have not been well described in the literature. The purpose of this study was to evaluate outcomes in patients receiving this strategy.

High-dose intravenous antifungal agents, including amphotericin B, are generally accepted as the first-line medical treatment, with prompt surgical resection of lesions if feasible. The body of evidence guiding treatment decisions, however, is sparse, particularly regarding adjustment of immunosuppression during acute infection and long-term recovery.

Summary Background Data: ECMO is beneficial in severe cases of respiratory failure when mechanical ventilation is inadequate. Outcomes for ECMO-eligible COVID-19 patients on MVA have not been reported. Consequently, a direct comparison between COVID-19 patients on ECMO and those on MVA has not been established.
The study aim was to examine the impact time in therapeutic range (TTR, International Normalized Ratio [INR] 2.0-3.0) has on survival and adverse events in patients receiving the HeartWare HVAD System in the ENDURANCE and ENDURANCE Supplemental Trials.

The purpose of this study was to describe the clinical course of COVID-19 in LVAD patients. A retrospective review was performed at our center; 28 LVAD patients who developed COVID-19 between March 2020 and March 2021, and six patients with a prior COVID-19 infection who underwent LVAD implantation, were identified and examined.

Specific evidence-based recommendations on both protocols and indications are lacking. We retrospectively assessed left ventricular assist devices-bridged candidates who received pre-HT desensitization therapy.

Methods: A multicenter, retrospective cohort study was conducted. The cohort consisted of adult patients (18 years of age and older) requiring ECMO in the period from March 1, 2020, to September 30, 2020.
Hemodynamic support with continuous-flow left ventricular assist device (CF-LVAD) therapy has proven a reliable treatment for advanced heart failure. Although modern LVADs are highly durable, device failure and infection can be resolved with surgical exchange of pump components. In this study, we investigated the incidence and outcomes of LVAD exchange with the HeartMate II and HeartWare HVAD.

Recommendations exist to replace dysfunctional mechanical mitral valves and any mechanical aortic valves at the time of LVAD implantation. Due to potential increases in cardiopulmonary bypass time and associated comorbidities with valve replacement, leaving a functional mechanical valve in place at LVAD implantation has been suggested to be a safe option.

Device exchange has been the suggested treatment option. The aim of this study was to evaluate the long-term clinical outcomes of patients with an STS supported on an ungrounded cable.

Methods: We randomly assigned patients with advanced heart failure to receive either the centrifugal-flow pump or the axial-flow pump irrespective of the intended goal of use (bridge to transplantation or destination therapy). The composite primary end point was survival at 2 years free of disabling stroke or reoperation to replace or remove a malfunctioning device.
Background: Left ventricular assist device (LVAD) implantation for advanced heart failure is known to improve survival, functional capacity, and quality of life. Most patients implanted with LVADs suffer from moderate to severe malnutrition and deconditioning due to their advanced disease. The Mini Nutritional Assessment (MNA) and the short form of the survey (MNA-SF) are 2 well-validated clinical tools, previously used to assess patient nutrition status in numerous conditions.

Background: The ENDURANCE trial demonstrated noninferiority of the HeartWare HVAD System versus control (HeartMate II) in patients with advanced heart failure ineligible for heart transplantation. However, stroke was more common in HVAD subjects.
Introduction: Inflammatory processes are well-characterized risk factors in cardiovascular disease including advanced heart failure. Previous studies have utilized individual white cell subtypes in risk analysis, and a recent study has focused on the efficacy of the neutrophil-to-lymphocyte ratio in evaluating negative outcomes following left ventricular assist device implantation. To investigate the interaction between the left ventricular assist device and white cell counts, we assessed longitudinal changes in neutrophil-to-lymphocyte ratio following left ventricular assist device implantation.
