First Clinical Experience With the Pressure Sensor–Based Autoregulation of Blood Flow in an Artificial Heart
This report details the reliability and efficacy of the autoregulation device control mechanism (auto-mode), designed to mimic normal physiologic responses to changing patient needs. Hemodynamic data from a continuous cohort of 10 patients implanted with the device, recorded over 1,842 support days in auto-mode, were analyzed with respect to daily changing physiologic needs. The C-TAH uses embedded pressure sensors to regulate the pump output. Right and left ventricular outputs are automatically balanced. The operator sets target values and the inbuilt algorithm adjusts the stroke volume and beat rate, and hence cardiac ou...

Management of Intracranial Hemorrhage During Pulsatile Long-Term Biventricular Support: When Necessity Is the Mother of Invention
We present the case of a 48 year old man with advanced heart failure (INTERMACS 3) and severe biventricular dysfunction who underwent biventricular pulsatile paracorporeal device implantation (Berlin Heart Excor) as a bridge to candidacy. Although on the heart transplantation waiting list, the patient experienced an intracranial hemorrhage, which was successfully managed by switching to a less thrombogenic biventricular assist device (Levitronix Centrimag) using the Excor cannulae, thus enabling temporary withdrawal of antithrombotic therapy. Heart transplant was performed successfully with no significant complications.

In-hospital Outcomes of Left Ventricular Assist Devices (LVAD) Patients Undergoing Noncardiac Surgery
An increasing number of stage D heart failure patients are supported with left ventricular assist devices (LVADs), and the management of LVAD patients who require noncardiac surgery (NCS) presents unique challenges. Using the 2010–2014 National Inpatient Sample, we identified all adult cases of LVAD patients undergoing noncardiac surgeries using ICD-9-CM codes. We estimated inpatient mortality, bleeding complications, stroke, length of stay (LOS), and cost of hospitalization of the admissions related to NCS using mixed effects logistic and linear mixed regressions, respectively. A total of 30,323 patients with LVADs unde...

Ischemic Stroke and Intracranial Hemorrhages During Impella Cardiac Support
Impella is a percutaneously placed, ventricular assist device for short-term cardiac support. We aimed to study acute neurologic complications during short-term cardiac support with Impella. We reviewed prospectively collected data of 79 consecutive persons implanted with Impella at a single tertiary center. Acute neurologic events (ANE) were defined as ischemic strokes or intracranial hemorrhages. Among those with ANE, specific causes of ischemic and hemorrhagic events were collected and discussed. Of 79 persons with Impella with median 8 days of support (range 1–33 days), six (7.5%) developed ANE at a median of 5 days ...

Consider the Promises and Challenges of Medical Image Analyses Using Machine Learning
Medical imaging saves millions of lives each year, helping doctors detect and diagnose a wide range of diseases, from cancer and appendicitis to stroke and heart disease. Because non-invasive early disease detection saves so many lives, scientific investment continues to increase. Artifical intelligence (AI) has the potential to revolutionize the medical imaging industry by sifting through mountains of scans quickly and offering providers and patients with life-changing insights into a variety of diseases, injuries, and conditions that may be hard to detect without the supplemental technology.
Images are the largest source...

What ’s the Big Deal about Data in Medtech?
Discussion, “Top 5 Things You Need to Know about the Implantable Internet of Things."
Brian Chapman, partner and leader of ZS’s medtech practice of ZS, attributes today’s focus on data to the intersection of two important things:
"A general recognition that understanding more and connecting actions with outcomes will provide feedback and understanding that will drive standards of care. This is not new, but as capabilities rise in data collection, aggregation, and synthesize rise, and coupled with machine learning, the promise of data in healthcare is becoming even more ...

Bloodstream Infections in Continuous Flow Left Ventricular Assist Device Recipients: Diagnostic and Clinical Implications
Bloodstream infection (BSI) is a common complication of left ventricular assist device (LVAD) support and particularly difficult to treat. The presentation is often variable because of altered physiology and augmentation of cardiac output by the device. We studied LVAD recipients at a single institution. Multivariate logistic and Cox (with time-varying parameters) regression were implemented. Of 212 patients, 58% experienced infections. Driveline infection (DLI) affected 31%, with 60% of them having deep-tissue involvement. Sixty-six patients (31%) suffered from 135 BSIs. Systemic inflammatory response syndrome (SIRS) was ...

AI is a Big Part of Cleveland Clinic ’s 2019 MIS
CLEVELAND – Two words dominated much of the program agenda for Cleveland Clinic’s 2019 Medical Innovation Summit (MIS) on Tuesday – Artificial Intelligence.
From a keynote address from Craig Mundie, Senior Advisor to the CEO, and former Chief Research and Strategy Officer, Microsoft to a session discussing companies with non-traditional approaches to healthcare, the topic of AI was discussed.
But is AI just the latest fad in healthcare? Is it fully-defined? And are there real-world examples to look to, to see AI in action? Richard Zane, MD CIO of University of Colorado ...

A Blood Filter Fights Deadly Inflammatory Response
A new blood filtration technology may prove to be life-saving for patients whose normally healthy inflammatory response to injury or illness has gone into overdrive, resulting in fatally high levels of cytokines in their blood. In an interview with MD+DI, Dr. Phillip Chan, MD, PhD, CEO of CytoSorbents Corp., explained that inflammation, and the production of substances called cytokines that drive inflammation, are the body’s natural response to heal injury or infection. But sometimes, the inflammatory response is so severe in such conditions as sepsis and infection, burn injuries, trauma, pancreatitis, li...

Medtronic and Viz.ai Look to Improve Stroke Outcomes with New Alliance
A collaboration between Viz.ai and Medtronic could lead to better outcomes for stroke patients. Through the distribution agreement, San Francisco, CA-based Viz.ai would increase the reach of its artificial intelligence solution for stroke.
Viz.ai’s solution identifies suspected large vessel occlusion (LVO) strokes and automatically notify specialists. It could lead patients to get treatment by technologies like Dublin-based Medtronic’s Solitaire revascularization device.
“By combining AI software with therapy that works, that’s how we can truly improve...

How Did Medtronic ’s HVAD Perform in LATERAL Trial?
Medtronic’s HeartWare HVAD pump system could get a significant boost after performing well in the LATERAL clinical trial.
The Dublin-based company presented results from the study at the American Society for Artificial Internal Organs 65th Annual Conference, that showed patients who received the system had 95% freedom from disabling stroke at two years.
The medtech giant now plans to launch a global registry to collect additional clinical evidence to further characterize survival, adverse events, and economic benefits of the HVAD System.
The HVAD Pump is a left ventricle assist device (LVAD) approved in t...

Medtronic touts stroke data from HeartWare HVAD thoracotomy study
Medtronic (NYSE:MDT) today touted stroke data from the Lateral trial of its HeartWare HVAD left ventricular assist device involving implantation via thoracotomy instead of open surgery.
With a thoracotomy implantation, surgeons insert the pump via a small, lateral incision between the left ribs and make a second small incision to accommodate the pump’s outflow graft. Fridley, Minn.-based Medtronic said Lateral results presented at the annual meeting of the American Society for Artificial Internal Organs showed that 95% of thoractomy patients were free from disabling stroke at two years.
Adverse events were more like...

Medtronic touts stroke data for HeartWare LVAD
A retrospective analysis of two studies involved the HeartWare left-ventricular assist device Medtronic (NYSE:MDT) acquired in 2016 showed that managing blood pressure reduced the severity of strokes in patients implanted with the HVAD pump.
The analysis, of “destination therapy” patients who are not candidates for a heart transplant, took data from the Endurance and Endurance Supplemental studies. Results were presented this week at the annual meeting of the International Society for Heart & Lung Transplantation in London, Medtronic said.
The 465-patient Endurance Supplemental study compared 308 patients i...
