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

Trial confirms the effectiveness of TAVR strategy in a real-world setting

Patients who underwent transcatheter aortic valve replacement (TAVR) did not have a higher rate of death at one year compared with those who had their heart valve replaced via open-heart surgery, according to research presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology.

TAVR shows high rate of success and low risk of death in patients with bicuspid valve

Transcatheter aortic valve replacement procedures had a high rate of success and low risk of death or disabling stroke at 30 days in patients with a bicuspid, or two-leaflet, aortic valve, according to research presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology.

Heart valve that grows with the child lowers the need for risky multiple heart surgeries

A breakthrough medical technology can save the lives of children with heart defects. Scientists have developed the first-ever heart valve that grows with the child, reducing the need for risky heart surgeries in the future.

AI-based approach may allow EKGs to be used for detecting hypertrophic cardiomyopathy

An approach based on artificial intelligence may allow EKGs to be used to screen for hypertrophic cardiomyopathy in the future.

Study clarifies pros and cons of open-heart surgery versus TAVR for treating aortic stenosis

A new study from the Smidt Heart Institute at Cedars-Sinai and other centers nationwide shows that patients who underwent a minimally invasive transcatheter aortic-valve replacement, had similar key 5-year clinical outcomes of death and stroke as patients who had traditional open-heart surgery to replace the valve.

MCG scan shows promise in evaluating chest pain for acute coronary artery syndrome

Undiagnosed chest pain sends 8-10 million Americans to Emergency Departments annually, making it the second most common complaint. Emergency physicians must rapidly identify patients whose chest pain is cardiac-related.

Research favors the use of surgical aortic valve replacement in young and middle-aged adults

While transcatheter aortic valve replacement (TAVR) continues to expand its pool of eligible patients, open heart surgery- resulting in excellent patient survival and fewer strokes when compared to TAVR- is the best option for young and middle-aged adults with aortic valve disease- at least for now, according to a scientific presentation at the 56th Annual Meeting of The Society of Thoracic Surgeons.

AATS calls for transparency of clinical research data

In response to continued discussion on the validity of the conclusions of the EXCEL trial comparing coronary stenting to coronary bypass surgery, The American Association for Thoracic Surgery (AATS) has released a statement calling for the release of all trial data to help surgeons and patients make informed choices based on sound analysis.

Women with gestational hypertension have elevated cardiovascular risk later in life

Research published online today in Journal of the American College of Cardiology, confirms that women who have gestational hypertension or preeclampsia in at least one pregnancy will have higher cardiovascular risk than women without such a history, and that this elevated risk persists at least into their 60s.

New study may help better understand mechanisms that control blood pressure

Many questions remain about the mechanisms that control blood pressure, particularly in relation to hypertension.

More patients may opt for minimally invasive heart valve procedure

Since August, when the Food and Drug Administration approved a minimally invasive heart valve procedure for an expanded group of patients with aortic stenosis, Raj Makkar, MD, vice president of Cardiovascular Innovation and Intervention at Cedars-Sinai, says many more patients are opting for the procedure known as transcatheter aortic valve replacement.

High-risk surgical patients with severe aortic stenosis can benefit from new TAVR system

The Portico IDE study found that 30-day safety and one-year effectiveness outcomes of a novel self-expanding transcatheter aortic valve replacement (TAVR) system for patients with severe aortic stenosis (AS) at high or extreme-risk for surgery was noninferior to contemporary FDA-approved TAVR systems available in the United States.

Study: Revascularization with PCI or CABG prolongs survival in patients with left main disease

Patients with left main coronary artery disease (LMCAD) typically have a poor prognosis due to the large amount of myocardium at risk.

Mutated ciliary genes tied to heart valve birth defect

The heart pumps blood throughout the body to provide the needed oxygen and nutrients. In the heart, blood flows to get oxygen from the lungs to deliver to the cells. Some of the most important structures in the heart are the valves, because they prevent the backflow of blood, avoiding the mixture of oxygenated blood with the ones that still need to be oxygenated.

Antibiotic-impregnated shunt could prevent hydrocephalus infections, save millions

A new study reported that using shunt tubing impregnated with two common antibiotics is effective in preventing infection after brain surgery to relieve hydrocephalus. This simple but highly effective practice could save millions of pounds, prevent devastating brain damage, and shorten hospital stay and antibiotic use duration.

Researchers explore remodeling of cardiac tissues post-aortic valve replacement

University of Colorado Boulder engineers and faculty from the Consortium for Fibrosis Research & Translation at the University of Colorado Anschutz Medical Campus have teamed up to develop biomaterial-based "mimics" of heart tissues to measure patients' responses to an aortic valve replacement procedure, offering new insight into the ways that cardiac tissue re-shapes itself post-surgery.

Latest advances in cardiovascular medicine to be unveiled

Journalists looking to stay abreast of the hottest research in cardiology are invited to follow the press program for ESC Congress 2019, this year held together with the World Congress of Cardiology.

BIDMC scientists develop new imaging technique to identify patients with coronary artery disease

Coronary artery disease - caused by plaque buildup in the artery walls that constricts the flow of blood to the heart - is the most common form of heart disease and the leading cause of death for both men and women in the United States.

Catheter-based valve replacement procedure safe for patients with common heart defect

A new analysis conducted by investigators at the Cedars-Sinai Smidt Heart Institute shows for the first time that patients with a common heart defect who undergo catheter-based valve replacement procedures have the same survival and complication rates as patients without the defect who undergo the same procedure.
