Fibers for fibers – Textile implants repair the body

08/06/2022

We are nowadays already able to weave implants out of artificial fibers that can replace tissue or heal injuries. Different materials like polymers or nitinol are used to create flexible shapes. But the materials and their uses can still be improved.

3D printed, bioinspired heart valves

06/06/2022

Researchers have developed 3D printed artificial heart valves designed to allow a patient’s own cells to form new tissue. To form these scaffolds using melt electrowriting – an advanced additive manufacturing technique – the team has created a new fabrication platform that enables them to combine different precise, customized patterns and hence to fine-tune the scaffold’s mechanical properties.

Researchers find new approach to treating cardiovascular diseases

02/06/2022

A specific protein in blood vessel cells plays a major role in the development of vascular and cardiovascular diseases: The presence of too many "thromboxane A2 receptors" hinders the formation of new blood vessels. A research team led by the Martin Luther University Halle-Wittenberg (MLU) was able to describe the underlying process for the first time.

Ballistocardiography: Cardiac monitoring of astronauts

24/01/2022

It is an exciting time for space exploration: Will there be more space stations, lunar outposts, or Mars missions in the future? No matter where they are in space, lack of gravity causes astronauts to lose muscle mass during their missions. Even the fittest among them lose heart muscle. An experiment on the International Space Station (ISS) plans to detect whether sensors show heart changes.

Identifying risks before surgery - with simple means

08/10/2021

Risks during surgery, especially cardiological risks, are still very high in the Western world. However, conventional methods for measuring such risks before surgery are costly or even not always meaningful. And increasing economization in hospitals also makes it more difficult for staff to find time for a comprehensive pre-op analysis.

Everyday physical activity: out of shape thanks to the Corona pandemic?

22/09/2021

Social distancing, working from home, limited social activities: the COVID-19 pandemic has prompted many people to become more inactive, sedentary, and therefore more susceptible to ailments. Simple fitness programs and regular exercises can help counteract the negative effects of inertness. And paradoxical as it may sound, the pandemic also gives us the chance to get moving again.

Medical imaging: obtaining an accurate view of blood vessels for surgery

02/08/2021

Surgical intervention is often inevitable when blood vessels become narrowed, blocked, or damaged. Surgeons use stents and medical balloons to open and widen the arteries, suck out the obstructing clots and use a catheter to examine the vessels. Intraoperative cardiovascular imaging is an essential tool to guide the catheters and instruments during the minimally invasive procedures.

A look into the cardiovascular system: Possibilities of medical imaging

02/08/2021

A high degree of precision is required for operations involving the cardiovascular system. This is based on medical imaging. In practice, however, these still face a number of challenges that can impair image quality. The further development of imaging techniques represents a forward-looking field of research in order to be able to improve surgical treatment.

SWIR Imaging: The Power of Multi-Color Real-Time Technology

02/08/2021

Image-guided surgery is based on medical imaging. However, past imaging technologies performed while the patient is awake cannot deliver a complete view that facilitates a visual differentiation of structures such as blood vessels and nerve tracts. In a study, scientists developed a non-invasive imaging modality that enables multiplexing, deep tissue penetration, and real-time resolution.

Atrial fibrillation: better outcomes with diamonds

15/12/2020

Atrial fibrillation is an irregular heartbeat that can lead to blood clots and trigger strokes. To correct the condition, physicians use medication or surgical intervention by means of catheter ablation. This surgical method on the beating heart is a standard and safe procedure but there is always room for improvement.

Mobile stroke units: improved outcomes for ischemic stroke

02/06/2020

If someone is having a stroke, you call an ambulance. But getting to the hospital can be time-consuming. To prevent long-term disabilities and death, patients need to be treated as quickly as possible. According to a recent study by the Charité – Universitätsmedizin Berlin, mobile stroke units play a key role in this setting.

Stroke care: When every minute counts

02/06/2020

Stroke can affect anyone – older as well as younger people. The minutes after the stroke determine whether disability or death is the result. Only if acute care, inpatient treatment and rehabilitation are carried out in a targeted and effective manner, the chances are greater that only minor damage remains or that impairments even recede.

Cardiovascular diseases: using AI to navigate the catheter

09/03/2020

Treatment of a heart attack or stroke caused by vascular occlusion must be prompt to prevent further damage to vital tissue. Unfortunately, the actual treatment is often preceded by a lengthy catheter-based procedure where the cardiologist manually guides the catheter to the affected vessel. AI might perform this task in the future.

Digital cardiology: analyzing data beat by beat

03/02/2020

Chronic cardiovascular diseases are a growing burden worldwide. Most of them are diseases of civilization that spread, where lifestyle is improving or where it is good already. But the healthcare systems are not growing equally to keep up with this development. We can make up for this by making cardiological care smarter with eHealth and mHealth.

Cardiology: digital solutions support those coping with chronic illness

03/02/2020

According to the World Health Organization (WHO), cardiovascular diseases are the leading cause of death worldwide, taking an estimated 17.9 million lives each year. Acute events such as heart attacks and strokes stand out in this setting. Chronic heart diseases can also be a debilitating condition for many patients. If cardiology uses digital methods and tools, it can reach more affected people.

Cardiac arrhythmia: treatment in the linear accelerator

08/04/2019

Cardiac arrhythmia is a group of conditions where nerve cells trigger uncontrolled contractions of the heart muscle. They are treated with either medicine or catheter ablation of the tissue. In an interdisciplinary collaboration, cardiologists and radiotherapists took a different approach and used high-precision radiation therapy to treat a patient for whom the other options proved unfeasible.

WAKE-UP study a wake-up call for acute stroke care

08/08/2018

Some solutions are simple, though not necessarily obvious. The WAKE-UP study, which included 70 participating European stroke centers, has now studied a relatively simple procedure to manage the acute care of stroke patients and avoid potential long-term effects. Best of all, it is available wherever MRI is offered.

Tissue engineering: how to grow a bypass

23/04/2018

A bypass is a complicated structure. It is either made of synthetic materials that can cause blood clots and infections or created by using the patient’s veins. However, the latter often does not yield adequate material. A newly developed bioreactor could solve this problem in the future. It is designed to tissue engineer vascular grafts by using the body’s own material.
