Stenosis News and Research

RSS

A stenosis is an abnormal narrowing in a blood vessel or other tubular organ or structure.

Catheter-based procedure increases treatment options for mitral valve disease

Some heart patients haven't yet been able to access the growing trend toward minimally invasive procedures. A new clinical trial, though, makes a form of mitral valve repair an option without an open-heart surgery.

Biomedical engineers grow living windpipe structures from self-assembled modules

Biomedical engineers at Case Western Reserve University are growing tracheas by coaxing cells to form three distinct tissue types after assembling them into a tube structure-;without relying on scaffolding strategies currently being investigated by other groups.

Specialized stenting system found to be beneficial for certain stroke patients

A specialized stenting system used to open blocked arteries in the brain resulted in a low complication rate among a specific group of patients with stroke histories, a study led by Cedars-Sinai researchers has found.

Acarix announces study of handheld system for rapid, non-invasive CAD diagnosis

Acarix AB announced the initiation of a multi-center trial of its handheld CADScor System for non-invasive, non-radiation acoustic detection of Coronary Artery Disease.

Researchers develop novel organ-on-a-chip device that models atherosclerosis

When studying diseases or testing potential drug therapies, researchers usually turn to cultured cells on Petri dishes or experiments with lab animals, but recently, researchers have been developing a different approach: small, organ-on-a-chip devices that mimic the functions of human organs, serving as potentially cheaper and more effective tools.

Study opens up new avenues for stopping calcific aortic valve disease

The diminutive size of our aortic valve -- just shy of a quarter -- belies its essential role in pushing oxygen-rich blood from the heart into the aorta, our body's largest vessel, and from there to all other organs. Yet for decades, researchers have focused less on damaged valves than on atherosclerosis, the gradual hardening of the blood vessels themselves.

Genetic, ethnic background may be underlying factors for acquired laryngotracheal stenosis

Endotracheal intubation, in which a tube is inserted through the voice box (larynx) into the windpipe, and tracheotomy, in which surgery is undertaken to create a hole through the neck and into the windpipe (trachea) to facilitate breathing, are widely used in the hospital setting for elective surgery and in cases of serious illness or critical injury.

Trial shows cost-effectiveness of TAVR compared to SAVR in intermediate risk patients with aortic stenosis

Analysis of the PARTNER 2A trial and the SAPIEN-3 Intermediate Risk registry found transcatheter aortic valve replacement (TAVR) to be highly cost-effective compared with surgical aortic valve replacement (SAVR) in intermediate surgical risk patients with aortic stenosis.

Study provides insights into potential causes of spinal stenosis

A new study published in the Journal of Orthopaedic Research indicates that certain genetic changes are linked with an increased risk of developing lumbar spinal stenosis, a narrowing of the open spaces in the lower spine that can lead to pain in the legs when individuals walk.

New app uses smartphone camera to provide detailed information about heart health

Want to know how healthy your heart is? Now there's an app for that. In a proof-of-concept clinical trial, engineers at Caltech, Huntington Medical Research Institute, and USC have demonstrated that the camera on your smartphone can noninvasively provide detailed information about your heart's health.

ESC recommendations on management of patients with peripheral arterial diseases published

European Society of Cardiology Guidelines on the Diagnosis and Treatment of Peripheral Arterial Diseases, developed in collaboration with the European Society for Vascular Surgery (ESVS), are published online today in European Heart Journal, European Journal of Vascular and Endovascular Surgery, and the ESC website.

Researchers identify new way to predict which TAVR patients may be at risk for rehospitalization

As more elderly patients undergo the minimally invasive heart valve procedure called Transcatheter Aortic Valve Implantation (TAVR), concerns have been raised as to what causes some to be readmitted for heart failure after the procedure.

PinnacleHealth’s new technology helps protect patients from risk of stroke during TAVR

PinnacleHealth is the first hospital in Pennsylvania and one of the first 10 in the country to introduce new technology shown to help protect patients from the risk of stroke during transcatheter aortic valve replacement (TAVR).

Genetic test to predict IBD severity in children

Inflammatory bowel disease (IBD) is a chronic relapsing inflammation of the gastrointestinal tract with abdominal pain and diarrhea being the most common symptoms. It can be challenging to diagnose as gastrointestinal complaints mimicking IBD are common.

European scientists develop new handheld scanner for early-stage heart disease diagnosis

With worldwide cardiovascular deaths at an all-time high, European scientists have developed a new handheld scanner that can read your heart's vital signs like a supermarket barcode reader can scan items at the checkout, allowing a GP to diagnose even preclinical patients for the early onset of a disease.

Some seniors just want to be left alone, which can lead to problems

The 84-year-old man who had suffered a mini-stroke was insistent as he spoke to a social worker about being discharged from the hospital: He didn't want anyone coming into his home, and he didn't think he needed any help.

FDA approves expanded use of Sapien 3 THV as valve-in-valve treatment for high-risk patients

The U.S. Food and Drug Administration today approved an expanded indication for the Sapien 3 Transcatheter Heart Valve (THV) for patients with symptomatic heart disease due to failure of a previously placed bioprosthetic aortic or mitral valve whose risk of death or severe complications from repeat surgery is high or greater.
