Early surgical intervention may improve outcomes for patients with mitral valve disease

The number of patients undergoing mitral valve operations are at an all-time high, and new research posted online today in The Annals of Thoracic Surgery suggests that many patients don't undergo surgical intervention until it's too late to completely reverse damage caused by mitral valve disease.

FDA grants marketing authorization for use of two catheter-based devices in hemodialysis patients

Today, the U.S. Food and Drug Administration permitted marketing of two catheter-based devices designed to create a connection to veins and arteries in patients with chronic kidney disease who need hemodialysis.

Researchers evaluate left ventricular systolic function after pulmonary valve replacement

In the current issue of Cardiovascular Innovations and Applications (Volume3, Number 1, 2018, pp. pp. 21-30(10); DOI 10.15212/CVIA.2017.0050, Ali N. Zaidi and W. Aaron Kay from Columbus Ohio Adult Congenital Heart Disease Program, The Heart Center, Nationwide Children's Hospital and Division of Cardiovascular Medicine, Wexner Medical Center, The Ohio State University, Columbus, OH, USA and the Division of Pediatric Cardiology, The Heart Center, Nationwide Children's Hospital, The Ohio State University, Columbus, OH, USA consider how following reparative surgery for tetralogy of Fallot or critical pulmonary stenosis, patients frequently present with severe right ventricular volume overload due to pulmonary regurgitation, resulting in decreased RV function.

Naturally occurring antibody can block inflammation in mice, finds study

Researchers at University of California San Diego School of Medicine discovered that they can block inflammation in mice with a naturally occurring antibody that binds oxidized phospholipids, molecules on cell surfaces that get modified by inflammation.

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.
