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

Rutgers Cancer Institute nurses research various topics to enhance patient experience

From peer and patient education to addressing treatment side effects and other patient care needs, nurses at Rutgers Cancer Institute of New Jersey researched a number of topics with an aim of enhancing the patient experience.

Adding chemotherapy to treatment regimen can give children with PVS a chance to grow up

Pulmonary vein stenosis (PVS) is a rare disease in which abnormal cells build up inside the veins responsible for carrying oxygen-rich blood from the lungs to the heart. It restricts blood flow through these vessels, eventually sealing them off entirely if left untreated.

Medical marijuana use reduces pain and need for opioid painkillers, finds study

A questionnaire of older men and women suffering from chronic pain who were given medical marijuana found that the drug significantly reduced pain and their need for opioid painkillers, Northwell Health researchers report.

Study examines efficacy of 3D printing, computer modeling to predict paravalvular leak in TAVR

A new study examines the effectiveness of 3D printing technology and computer modeling to predict paravalvular leak in patients undergoing transcatheter aortic valve replacement (TAVR). A common risk of TAVR is an ill-fitting valve which can lead to PVL.

Researchers identify independent predictors of both delayed and early discharge post TAVR

A new study finds patients who stay in the hospital for more than 72 hours when undergoing trans-femoral transcatheter aortic valve replacement (TF-TAVR) procedure may be associated with negative short and long-term outcomes.

Common therapy options for psoriasis can help reduce coronary plaque, study shows

Late-breaking clinical science shows common therapy options for psoriasis (PSO)-a chronic inflammatory skin disease-can help reduce coronary plaque. The authors found that not only do the treatments reduce the volume of the plaque, but also the plaque becomes less inflammatory over time harboring fewer characteristics prone to rupture and cause a heart attack.

Researchers present case study of management of rheumatic mitral regurgitation in woman contemplating pregnancy

In the current issue of Cardiovascular Innovations and Applications (Volume 2, Number 4, 2018, pp 439-446(8); DOI: https://doi.org/10.15212/CVIA.2017.0027, researchers Yee-Ping Sun and Patrick T. O'Gara, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA present a case study of management of rheumatic mitral regurgitation in a woman contemplating pregnancy.

Researchers compare mouse and human blood vessels under ischemic conditions

Peripheral obstructive arterial disease develops when blood vessels narrow due to arteriosclerosis and blood flow in the legs (or rarely the arms) becomes clogged. Intermittent claudication is when blood flow disturbances in a limb causes pain, numbness, or coldness during physical activity.

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.

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.
