Mechanical heart valves are so loud that they cause insomnia

A quarter of patients with mechanical heart valves claim that the valves disturb their sleep, according to a new study. “For some patients, the closing sound of their mechanical heart valve reduces their quality of life, disturbs their sleep, causes them to avoid social situations and leads to depression and anxiety,” said Kjersti Oterhals, a

Artificial intelligence accurately predicts stroke risk

Machine-learning algorithms, a form of artificial intelligence, accurately predicted people’s risk of heart disease and stroke, according to new research from the University of Nottingham. Researchers and computer scientists compared the risk guidelines for heart disease and stroke from the American College of Cardiology with 4 machine-learning algorithms to analyze the risk of a patient

What is catheter (PTCA) treatment?

Asahi Intecc Catheter treatment (percutaneous transluminal coronary angioplasty, or PTCA, treatment) is one of the methods of treatment for diseases such as angina pectoris and myocardial infarctions that are caused by the heart’s blood vessels (coronary arteries) becoming clogged or narrowed by cholesterol. Previously it was common to treat such diseases with medication or, if

Deaths prompt Abbott recall of Thoratec HeartMate II controllers

Brad Perriello, Executive Editor Abbott (NYSE:ABT) is recalling nearly 29,000 controllers for the HeartMate II implantable heart pump made by its Thoratec subsidiary after 26 patients died trying to change out the controllers on their own. The March 29 recall of 28,882 controllers for the HeartMate II left ventricular assist device follows 70 reports of

This could be the battery-free solution for pacemakers

A new energy storage system charges itself using ions from inside the human body – providing an exciting alternative to traditional batteries used in pacemakers, according to researchers at the University of California at Los Angeles and the University of Connecticut. Researchers at the universities developed a bio-friendly energy storage system called a biological supercapacitor;

Apple Watch detects atrial fibrillation using built-in technology

The Apple Watch can automatically detect atrial fibrillation (AF) using its built-in heart rate sensor and artificial intelligence, according to a new study. The research used a deep neural network that was based on photoplethysmographic (PPG) sensors that are frequently found in smart watches. When paired with an artificial intelligence-based algorithm, Apple Watch’s heart rate

‘No-touch’ heart bypass surgery reduces strokes

A recent study from the University of Sydney and Sydney Heart and Lung Surgeons has shown that a new “no-touch” beating heart bypass surgery technique has reduced post-operative stroke by 78%. The procedure, known as an OPCABG, also reduced post-operative mortality by 50% compared to traditional coronary artery bypass grafting. It reduced renal failure by

Could wireless signals help diagnose diseases?

Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory (CSAIL) has developed a wireless device that is the size of a small painting and could help diagnose cognitive decline and cardiac disease – all through wireless signals. The device, deemed WiGait, measures the walking speed of people with 95 to 99% accuracy using wireless

This new ‘smart shirt’ can monitor your vital signs

Holst Center researchers have created a smart shirt that uses state-of-the-art printed electronics technology to track vital signs. IMEC, a Belgian research and development and innovation hub that specializes in nanoelectronics and digital technologies, developed a medical-grade electrocardiogram (ECG) with breathing rate and breathing depth. Researchers at Holst in the Netherlands used the IMEC ECG

How Boston Sci is getting drug-eluting stents and balloons into legs

Boston Scientific officials think they have a leg up when it comes to bringing drug-eluting technology to bear on peripheral artery disease. That’s because the medical device giant has decades of experience with balloons and drug-eluting stents used around the heart. When it comes to treating the narrowing arteries in the legs and thighs, Boston

This smartphone app accurately screens for heart arrhythmia

Maybe a selfie can help after all. The Media Lab at Massachusetts Institute of Technology has developed a mobile app that uses a smartphone’s camera to detect signs of a heart arrhythmia. Evaluating a person’s facial expressions is one of the ways to determine if someone is experiencing a stroke. The MIT app measures and

How deep learning could change diagnostic imaging forever

Computational imaging is a passion for Fabein Beckers. As the CEO of Arterys, Beckers thinks he can revolutionize how doctors on a global scale work with imaging diagnostics. In that vein, Beckers and his team launched Arterys, which enables clinical visualization and accurate quantification of blood flow inside the body. It measures 7 dimensions of data (3 in

Growing human hearts: The answer is spinach leaves?

We could someday be using spinach to grow human hearts, thanks to new research from the Worcester Polytechnic Institute, the University of Wisconsin-Madison and Arkansas State University. One of the problems that researchers have faced is how to create a vascular system that can deliver blood deep into developing tissues. There hasn’t been much success

The top medtech stories of early 2017

The new Trump administration and Republican Congress – and all the accompanying change and uncertainty –is the major story for the medical device industry. But there are many other medtech stories worth noting from the first quarter of 2017. There was an FDA warning over Abbott’s Absorb bioresorbable stent, a continued spate of M&A deals, a

MR Solutions offers MRI imaging solution for cardiologists

MR Solutions has created 9.4 tesla cryogen-free, preclinical scanners that are ideal for use among cardiologists. The new helium-free Flexiscan and Powerscan scanners are powerful and have multi-modality by integrating PET and SPECT capabilities. The Flexiscan doesn’t need a specialist to operate and can be used by running pre-defined settings. The SPECT image system works by
