Endoscopy: images from the inside of blood vessels

29/07/2020

Researchers of the Universities of Stuttgart and Adelaide in cooperation with medical research centers in Australia developed a special microoptical tool with a thickness of only 125 microns. This enables endoscopic examimations within blood vessels whose diameter is smaller than 0.5 mm and helps detecting plaques or thrombs to reduce the danger of a stroke or a heart attack.

Active photonic wireless system to power medical implants

08/07/2020

Over the past few decades, medical technology seen various advances in terms of the scope and efficiency of implant devices. Developments in medical research have led to the emergence of electronic implants, such as pacemakers to regulate the heart rate and cerebral spinal shunts to control the flow of spinal fluid. Most of these medical devices require a constant source of energy to operate.

Gentle technique to study heart tissue functioning

03/07/2020

Biophysicists from the Moscow Institute of Physics and Technology and their colleagues have proposed a simple way to observe the heart tissue. Besides being relatively uncomplicated, the new method is cheaper and produces results that are more independent, compared with the analogues currently in use. The study came out in Annals of Biomedical Engineering.

COVID-19: virus can infect heart cells in lab dish

03/07/2020

A new study shows that SARS-CoV-2, the virus that causes COVID-19, can infect heart cells in a lab dish, indicating it may be possible for heart cells in COVID-19 patients to be directly infected by the virus. The discovery, published today in the journal Cell Reports Medicine, was made using heart muscle cells that were produced by stem cell technology.

New heart valve could transform open heart surgery

30/06/2020

A new polymeric heart valve with a life span potentially longer than current artificial valves that would also prevent the need for the millions of patients with diseased heart valves to require life-long blood thinning tablets has been developed by scientists at the universities of Bristol and Cambridge. The team’s latest in-vitro results suggest that the PoliValve could last for up to 25 years.

Tissue Engineering: heart attack in a dish

16/06/2020

A team of investigators at the Medical University of South Carolina (MUSC) and Clemson University recently reported in an article in Nature Biomedical Engineering that they have developed human cardiac organoids less than 1 millimeter in diameter that closely resemble the physiological conditions that occur during a heart attack.

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.

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.

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.

Cardiac diagnostics – prompt and personalized

08/11/2019

If physicians suspect an acute myocardial infarction, they first order an ECG. This test is very established and allows cardiologists to quickly diagnose acute heart attacks – though the test does not detect less common heart attack symptoms. So far, those patients had to wait up to twelve hours before a heart attack could be accurately diagnosed or ruled out. But things are about the change.

MEDICA TECH FORUM: light-based imaging technique OCT

04/11/2019

Since its inception, MEDICA TECH FORUM has focused on the implementation of innovations and new technologies into clinical practice. 2019 marks the tenth year of the Forum. In honor of its anniversary, we will brighten things up a bit, as one of the focal points will highlight how optical coherence tomography (OCT) uses light to produce images.

Cardiac Tissue Engineering: a heart out of the Petri dish

23/09/2019

For patients waiting for donor organs, every day can mean the difference between life and death. Making things even more complicated is the fact that not every organ is a compatible match with the patient. It would mean enormous progress if we could grow organs from the patient's own cells in the lab. That's why patients with heart disease place big hope in tissue engineering.

mHealth: Atrial fibrillation detection – App supports heart health

08/05/2019

Atrial fibrillation is the most common type of persistent cardiac arrhythmia (irregular heart rhythm). Researchers estimate that 1.8 million Germans are presently affected by this disease. The condition is difficult to diagnose, frequently goes undetected and may result in a stroke. A new smartwatch medical app is designed to help patients detect atrial fibrillation before it’s too late.

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.

Regenerative heart valves: from simulation to replacement

23/07/2018

Every year, more than 250,000 patients worldwide receive heart valve implants. Children require repeated replacement surgery because their bodies are still growing, the prosthetic heart valves are not. Regenerative heart valves solve this problem. Until now, we have only been able to monitor how these living implants develop in the body after the fact. Computer models now make this predictable.

Resuscitation via videostream – how EmergencyEye can save lives

02/07/2018

When the heart stops beating, irreversible brain damage occurs within minutes without resuscitation. Meanwhile, action is only taken in very few instances of cardiac arrest. Even first responders frequently feel helpless in this situation. In Germany, approximately 65,000 people die each year from sudden cardiac arrest. This is where EmergencyEye comes in to offer valuable support.

Ventricular fibrillation – Using ultrasound to detect its causes

17/05/2018

Ventricular fibrillation is a life-threatening condition that occurs when the heart muscle exhibits a rapid, erratic beat. The cause might be a circulatory system disease or heart attack. Researchers in Göttingen are now developing an ultrasound technique to get to the bottom of ventricular fibrillation and cardiac arrhythmias and facilitate better treatment options.

Organ Care System: treatment under extreme conditions

08/05/2018

Multidrug-resistant organisms that are treated with a dosage that exceeds the regular dose a hundred times and at temperatures of over 40 degrees Celsius – the human organism is unable to handle it. Yet if the diseased organ is treated outside of the body, extreme conditions are an option. For the first time, physicians have succeeded in treating a severe case of pneumonia by using the OCS.

VR Lab for medical students: linking theory and practice

22/03/2018

Virtual reality and medicine are increasingly mentioned in the same context. In addition to the development of applications that support the treatment of patients suffering from chronic pain and anxiety, this technology also benefits medical staff. Two months ago, the Ulm University Hospital has opened the VR Lab, where medical students can train and learn with the help of 3D organs.
