Enhancing Renal Function A Revolutionary Approach with Axillary Mechanical Circulatory Support



Enhancing Renal Function: A Revolutionary Approach with Axillary Mechanical Circulatory Support

Challenges associated with impaired kidney function often accompany the acute decompensation of chronic heart failure, signaling a foreboding prognosis. Recent data underscores the precarious survival rates for patients with acute kidney injury undergoing durable left ventricular assist device (LVAD) placement, emphasizing the critical need for innovative solutions. This study explores a groundbreaking strategy centered on renal function recovery in heart failure patients awaiting transplantation, aided by temporary mechanical circulatory support (tMCS) with the revolutionary Impella 5.5 device.

Renal Function

Renal-function is an important part of general health. It means how well the kidneys filter and get rid of waste from the blood, keep the body’s fluid balance in check, and handle electrolytes. Renal-function is an important part of keeping balance, which means that the body’s metabolism stays stable and blood pressure stays under control.

Heart-failure and other conditions can cause problems that can make it hard for the kidneys to work properly. This shows how closely the heart and kidneys are connected. Understanding and improving renal function is very important for overall health. This has led to new methods like the Impella 5.5 for heart-failure patients, as shown in the Mayo-Clinic study, to help them recover from both heart-failure and kidney damage.


This study was given the green light by the Institutional Review Board at the Mayo-Clinic under protocol #22004000. A retrospective study was done, with a focus on patients with acute-on-chronic heart failure and kidney disease who were being considered for a heart and kidney combined organ transplant. The study took place from January 2020 to February 2021. Before and after tMCS implant and transplantation, changes in blood flow and kidney function were carefully looked at.

Patient Population and Impella Management

Six of the 57 people who had heart transplants were checked out for heart and kidney transplants while they were being managed by Impella 5.5. The kidney transplant team carefully checked out these people who had been labeled with chronic heart failure at least seven years before the transplant. Coordinated care by transplant critical care, transplant cardiology, and cardiothoracic surgery made sure that the Impella was managed in a normal way, with regular echocardiograms, hemodynamic assessments, and purge solutions based on heparin.


Patients had a median creatinine level of 2.1 mg/dL and an estimated glomerular filtration rate (GFR) of 34 mL/min/BSA before Impella treatment. Following Impella, there was an upward increase in creatinine, Fick cardiac index, mixed venous saturation, and GFR. The median GFR went up from 34 to 44 mL/min/BSA, and blood creatinine went down from 2.1 mg/dL to 1.5 mg/dL. Surprisingly, none of the six patients who had heart transplants needed renal replacement treatment.


In cardiorenal syndrome, the heart and kidneys don’t work together properly, which can make it easier for salt and water to build up and cause oxidative stress. Few studies have been done on renal recovery in people who are in cardiogenic shock and are being treated with tMCS. However, this study showed that the Impella 5.5 device had a big effect on improving kidney function.

Exploring the Implications

The important effects of this study go far beyond the direct effects on patients. The link between sudden decompensation of heart failure and renal function shows how important it is to use non-traditional approaches to help people. Traditional bridge treatments have their limits. The Impella5.5, a temporary mechanical circulatory support device, changes the way heart and kidney conditions are treated in complicated ways.

Navigating the Landscape of Heart and Kidney Transplantation

Organ Procurement and Transplantation Network (OPTN) data from across the country stresses how important it is to have a heart and kidney transplant at the same time. However, new cases raise questions about whether kidney damage can be fixed. The study’s focus on heart failure patients at the MayoClinic and its look at heart and kidney transplants together adds a useful layer to this conversation. The six patients who received Impella5.5 support not only dodged renal replacement therapy after transplantation, but they also showed better kidney function, which goes against what most people think.


The introduction of Impella 5.5 as a temporary mechanical circulatory support device marks a major step forward on the path towards enhancing renal function in patients with severe heart failure. This is because the Impella5.5 is the first device of its kind. Not only does this study give information on the beneficial outcomes that were observed in a specific set of patients, but it also highlights the necessity for continued exploration and validation. Patients who are in need of novel and effective treatments have a glimmer of hope thanks to a new treatment called Impella5.5, which has a significant possibility of reshaping the landscape of heart and kidney problems.

Blue tongue Alert: Norfolk Livestock Farmers Navigate New Challenges



Blue tongue

Expanding Control Zones: Norfolk’s Battle Against Blue tongue Outbreak

Norfolk’s livestock farming community faces a heightened challenge as the bluetongue control zone expands in response to new cases of this potentially fatal animal disease. Bluetongue, affecting ruminants such as cattle, sheep, goats, deer, and camelids, has raised concerns after the confirmation of two infected cattle on a holding near Norwich. The total number of cases in the county has now reached 21 since the initial discovery on a Cantley farm in the Broads on December 8, signaling the need for increased vigilance and control measures.

 Blue tongue

The regulatory authority in charge of such matters, the Department for Environment, Food & Rural Affairs (Defra), recently confirmed the extension of the temporary control zone (TCZ) in response to the latest developments. This 10-kilometer zone was initially established to facilitate focused surveillance efforts and restrict livestock movements, aiming to prevent the disease’s further spread. All preceding cases were contained within the TCZ, but the most recent instances involved animals grazing just outside the zone during a high-risk period. Consequently, the TCZ’s boundaries have been adjusted, extending it toward Norwich to address this evolving situation effectively.

An interesting departure from previous protocol is the decision not to cull the infected animals this time. Defra has opted for an alternative approach, restricting these animals at their current locations and implementing disease mitigation measures. This strategic shift is attributed to a recent reduction in midge activity, diminishing the risk of onward transmission. The link between bluetongue and infected midges is crucial to understanding its spread, as it is believed that the disease was introduced to Norfolk and Kent by these tiny vectors, carried across the Channel from Europe during optimal wind and temperature conditions in September or October.

However, despite the absence of evidence suggesting the disease’s circulation through midges in the UK, precautionary measures within the TCZ are causing disruption and uncertainty for local livestock farms. Specific licenses are now mandatory for moving animals out of the zone, with permission granted only under circumstances of “urgent and genuine welfare need” or for direct transportation to a designated abattoir. This has added an extra layer of complexity for farmers who must navigate these restrictions while ensuring the well-being of their livestock.
