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

Custom, 3D-printed robotic heart could help doctors to tailor patient-specific treatments

No two hearts beat alike. The size and shape of the the heart can vary from one person to the next. These differences can be particularly pronounced for people living with heart disease, as their hearts and major vessels work harder to overcome any compromised function.

Morristown Medical Center reaches significant milestone of performing over 4,000 TAVR

Morristown Medical Center's Gagnon Cardiovascular Institute's structural heart program reached a significant milestone of performing over 4,000 transcatheter aortic valve replacement (TAVR) procedures with well over 650 in 2022 alone.

Study shows the potential of a game-changing drug to treat upper urinary tract urothelial cancers

A team from 15 U.S. medical centers led by UT Southwestern Simmons Cancer Center researchers has performed the first analysis of a potentially game-changing drug to treat upper urinary tract urothelial cancers.

Benefits, challenges in the use of transcatheter pulmonary valve replacement for congenital heart disorders

Patients with congenital heart diseases often suffer from obstructions in the right ventricular outflow tract (RVOT), which carries blood from the heart to the lungs. These obstructions can be repaired with surgical procedures.

Machine learning used to generate a new holistic model for coronary artery disease

A recent study published in the Lancet journal investigated whether a quantitative in-silico score for coronary artery disease (ISCAD), based on a machine learning model, can be used as a clinical marker to detect coronary artery disease.

Mount Sinai researchers construct a computer-derived marker for coronary artery disease

Using machine learning and clinical data from electronic health records, researchers at the Icahn School of Medicine at Mount Sinai in New York constructed an in silico, or computer-derived, marker for coronary artery disease (CAD) to better measure clinically important characterizations of the disease.

AI tool uses CT scans to identify patients at risk of reduced blood flow to the heart

Cedars-Sinai investigators and colleagues have developed an artificial intelligence (AI) tool that uses computed tomography (CT) scans to identify patients at risk of reduced blood flow to the heart.

Amplification of venous thromboembolism risk by COVID-19 among malignancy patients

In a new study, researchers reported the mechanisms involved in COVID-19 coagulopathy and the significance of SARS-CoV-2 infections for cancer patients concerning outcomes, thromboembolic complication risks, and consequences of management strategies.

Study examines the link between different types of grain intake and premature coronary artery disease

In one of the first studies to examine the relationship between different types of grain intake and premature coronary artery disease in the Middle East, researchers found a higher intake of refined grain was associated with an increased risk of premature coronary artery disease in an Iranian population, while eating whole grains was associated with reduced risk.

Minimally invasive procedure enables patients to be out of the hospital within a few days

Minimally invasive, catheter-based transcatheter aortic valve replacement (TAVR) has revolutionized treatment of aortic stenosis (AS), and both American and European guidelines have approved its use. However, there is a perception that TAVR is more expensive than surgical aortic valve replacement (SAVR). A budget impact analysis comparing the two options now shows that TAVR is an affordable and effective strategy for the treatment of AS. The study appears in the Canadian Journal of Cardiology, published by Elsevier.

A simple and low-cost method to identify valve dysfunction

Aortic valve stenosis occurs when the aortic valve narrows, constricting blood flow from the heart through the artery and to the entire body.

New risk assessment tool predicts mortality for atrial fibrillation patients after completion of TAVR

A large-scale international study led by Mount Sinai has yielded the first risk score that can help predict mortality for patients with atrial fibrillation (AFib) who have undergone a successful transcatheter aortic valve replacement (TAVR) and discharged home.

Healthy people over 65 years of age recommended to get a heart check-up before non-cardiac surgery

A heart check-up is recommended in even apparently healthy people over 65 years of age before intermediate- or high-risk non-cardiac surgery, according to European Society of Cardiology (ESC) Guidelines on cardiovascular assessment and management of patients undergoing non-cardiac surgery published online today in European Heart Journal.

Novel non-invasive detection technique detects carotid artery stenosis

Motion analysis of video recorded on a smartphone accurately detected narrowed arteries in the neck, which are a risk factor for stroke, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Specific form of age-related macular degeneration linked to cardiovascular disease and stroke risk

Patients with a specific form of age-related macular degeneration (AMD), a leading cause of blindness in the United States, are at significant risk for cardiovascular disease and stroke, according to new research from New York Eye and Ear Infirmary of Mount Sinai.

Patients with very narrowed neck arteries have low risk of future stroke, study shows

The risk of having a future stroke caused by a severe blockage in an artery in the neck that is not currently causing any symptoms is so low that most patients with this condition -; asymptomatic carotid stenosis -; could potentially be treated with the newest medications and may not require surgery, new Kaiser Permanente research suggests.
