Managing A Fungal-Infected Prosthetic Aortic Graft with Robotic-Assisted Closed-Chest Techniques

In May 2022, researchers from Lenox Hill Hospital Department of Cardiovascular and Thoracic Surgery provided a case report on the treatment of a fungal prosthetic graft infection using a robotic-assisted debridement of the aortic graft within a closed chest. The complete report by Ashley T. Giammarino, Iam Claire Sarmiento, SJacob Scheinerman, John Winalski, Richard S. Lazzaro, Derek R. Brinster, and Jonathan M. Hemli can be found in the Journal of Medical Case Reports. The case report is summarized below.

Although prosthetic vascular graft infections are uncommon, they are associated with high mortality. Traditional management usually involves graft excision and radical removal of damaged tissue through an open approach. Still, the high morbidity associated with these procedures has led to a search for alternative treatment options.


Evaluating Interfacility ECMO Transfer Outcomes by Cannulation Location and Mode of Transport

A study published in March 2022 evaluated complications and in-hospital mortality in patients treated with Venovenous (VV) ECMO based on cannula locations and transport mode. The manuscript, written by Jillian K. Wothe, Zachary R. Bergman, Krystina R. Kalland, Logan G. Peter, Elizabeth R. Lusczek, and Melissa E. Brunsvold at the University of Minnesota, can be found in Critical Care Explorations. The results of the study are detailed below.

Extracorporeal membrane oxygenation (ECMO) is a lifesaving measure for critical respiratory and cardiac failure. Unfortunately, the volume of adult patients requiring ECMO continues to increase, increasing the number of patients transported to an ECMO center. While previous studies have reported overall survival rates in patients transported on ECMO, this is one of only a few studies examining complication rates after interfacility ECMO transport and mode of transport comparison.


The Inspired Therapeutics Neomate MCS System for Neonates and Infants

In May 2022, scientists from the University of Louisville (Departments of Cardiovascular and Thoracic Surgery, Bioengineering, Anesthesiology, and Perioperative Medicine), Veritium research LLC, and Inspired Therapeutics LLC tested the NeoMate mechanical circulatory support (MCS) system for neonates and infants. The complete manuscript by Gretel Monreal, Steven C. Koenig, Mark S. Slaughter, Gino F. Morello, Steven R. Prina, Landon H. Tompkins, Jiapeng Huang, Barry N. Gellman, and Kurt A. Dasse can be found in Plos One. Their research is summarized below.

Up to 14,000 US children are hospitalized yearly with heart failure (HF)-related conditions. These children show a mortality rate of 7-15%, while the mortality rate of those on the waiting list for a heart transplant ranges from 5-39%. Because of these statistics, temporary and durable mechanical circulatory support devices prove to be important in supporting this patient population.


FDA recall for The HeartWare Ventricular Assist Device (HVAD) by Medtronic, Inc.

The FDA has identified this as a Class I recall for The HeartWare Ventricular Assist Device (HVAD) by Medtronic, Inc., the recall is due to welding defects that allow separation of the two cell battery packs used to power the system. The welding defect may cause the battery to malfunction and no longer provide power or prevent the battery from holding a full charge or properly recharging. As a result, the battery may fail suddenly. If this malfunction occurs, it will trigger a Power Disconnect alarm on the controller screen and in the Alarm Log tab of the HVAD Monitor while the affected battery is still connected to the controller.


Successful Coronary Artery Bypass Grafting in A Patient with Situs Inversus Totalis

In March 2022, a research team from Gunma University detailed the treatment of CABG in situs inversus totalis, a rare anomaly that has been minimally reported in the literature. The complete manuscript by Atsushi Oi, Wataru Tatsuishi, Jun Mohara, Toshikuni Yamamoto, and Tomonobu Abe was published in the Journal of Cardiothoracic Surgery. The case report is detailed below.

Dextrocardia with situs inversus totalis is a congenital anomaly where the organs are mirrored in relation to their typical locations. It is a rare condition, occurring in only 1:10,000 people, and as such, it has been minimally documented.


Endovascular Embolization as a Treatment for Subdural hematoma in LVAD Patients

In March 2022, practitioners from the Department of Neurosurgery at Georgetown University School of Medicine described a case study of a 63-year-old female with a preexisting LVAD who received treatment for a chronic subdural hematoma. Below we have summarized the findings from the case report, with the entire manuscript, written by Gnel Pivazyan, Mitchell B. Rock, Ehsan Dowlati, Jeffrey C. Mai, and Robert B. Mason, published in Brain Circulation.

Left ventricular assist devices (LVADs) play an essential role in those with heart failure by providing mechanical circulatory augmentation. However, a unique challenge for those with LVADs is chronic subdural hematomas (cSDH), a type of intracranial hemorrhage, which requires the patient to take continuous anticoagulation medication due to the high risk of thrombotic events.


A Review of the Global Healthcare Simulation Economy

In February 2022, researchers from Seattle Children’s Hospital and the University of Washington School of Medicine took an in-depth look at health simulation, its economic impact, and significant hurdles to its widespread acceptance. The full manuscript, written by Taylor Sawyer, Megan M. Gray, and Rachel Umoren, is available on the Cureus website. Below is a summary of their findings.

An expanding area of healthcare involves simulation, a technique that allows for improved practice, learning, evaluation, or understanding of human actions or systems without endangering real-life patients. The benefits of healthcare simulation include improvements in patient clinical care and outcome, leading to its rapid growth over the last decade.

The review by Sawyer et al. predicts a continued expansion of the global healthcare simulation market’s products and services. A 2019 estimate of the worldwide healthcare simulation market placed its value between $1.42 to 2.27 billion, while the market is projected to reach $3.19 to $7.7 billion by 2027.


Best Practice Recommendations for Optimizing Care in Structural Heart Programs Using PEARLS

In light of the impact of the COVID-19 pandemic, researchers from coast to coast worked together to offer recommendations for best practices in Planning Efficient and Resource Leveraging Systems (PEARLS) in structural heart programs. The entire manuscript was written by Elizabeth M. Perpetua, Kimberly A. Guibone, Patricia A. Keegan, Roseann Palmer, Martina K. Speight, Kornelija Jagnic, Joan Michaels, Rosemarie A. Nguyen, Emily S. Pickett, Dianna Ramsey, Susan J. Schnell, Shing-Chiu Wong, and Mark Reisman and published in May 2021, can be found in Structural Heart. A summary of their best practice recommendations is outlined below.The COVID-19 pandemic has created an opportunity to refine patient care for structural heart disease (SHD). This evolves around optimal care, informally defined as “the right care for the right patient at the right place at the right time.” A patient’s treatment plan revolves around patient goals and preferences while also weighing risk versus benefit analysis. Additionally recommended when determining a treatment plan are a systemic assessment of Heart Team roles and functions, hospital capacity, and patient and procedural risks that can occur when more resources are used.


Renal Hemodynamics And Oxygenation in Critically Ill Patients and After Major Surgery

In May 2021, researchers from the University of Gothenburg Department of Anesthesiology and Intensive Care Medicine took an in-depth analysis of the health status of those with acute renal dysfunction due to health conditions such as early clinical septic shock, chronic renal failure, postoperative AKI, liver transplantation, and cardiac surgery with cardiopulmonary bypass. The complete manuscript, written by Sven-Erik Rickstein, Gudrun Bragadottir, Lukas Lannemyr, Bengt Redfors, and Jenny Skytte, can be found on the Kidney 360 website. The results of the study are detailed below.

The primary data set obtained by this study was renal oxygen, with its availability determined by the balance of renal oxygen delivery (RDO2) and renal oxygen consumption (RVO2). The results were then separated by the health condition contributing to acute renal dysfunction, with the following key findings.

Rickstein et al. first measured renal perfusion, filtration, and oxygenation in patients within 24-hours of hospital admittance due to early clinical septic shock. The results concluded that RDO2 was impaired in these patients due to renal vasoconstriction and the redistribution of blood flow away from the kidneys.


Uncovering Hot Topics in Healthcare Operations and Supply Chain Management

In March 2022, Imran Ali and Devika Kannan released a paper that sought to advance the body of knowledge surrounding healthcare operations and supply chain management through a literature review. The full manuscript by Ali et al. can be found in the Annals of Operations Research. The result of the literature review is detailed below.

The key to counteracting emergent diseases (such as the COVID-19 outbreak) and promoting the health and well-being of patients lies in the effective and efficient delivery of healthcare services. With the onset of the COVID-19 pandemic, the literature surrounding healthcare operations and supply chain management has seen immense growth. However, previous literature reviews possessed varying scopes and emphases focused on a specific topic.
