Catheter News and Research

RSS

In medicine, a catheter is a tube that can be inserted into a body cavity, duct, or vessel. Catheters . In most uses, a catheter is a thin, flexible tube ("soft" catheter), though in some uses, it is a larger, solid ("hard") catheter. A catheter left inside the body, either temporarily or permanently, may be referred to as an indwelling catheter. A permanently inserted catheter may be referred to as a permcath.

Catheter-based renal denervation provides a new concept for the treatment of hypertension

Hypertension significantly increases the risk of cardiovascular events and it is associated with high rates of disability and mortality.

New technology allows urologists to identify and remove bladder tumors more easily

UC San Diego Health is the first health system in San Diego County to offer a new technology that detects and monitors bladder cancer in both the clinic and operating room settings by using blue light, white light and an imaging dye that makes cancer cells glow florescent pink.

Candida auris infection without epidemiologic links to a prior outbreak

The Centers for Disease Control and Prevention (CDC) has classified Candida auris (C. auris) as an urgent public threat due to its role in elevating mortality, its ability to persist in hospital environments, and the high possibility of developing pan-drug resistance.

Study demonstrates effectiveness of a procedure done under the skin to treat uncontrolled hypertension

Hypertension remains poorly controlled worldwide and is becoming more common. Lifestyle changes and blood pressure-reducing drugs are the mainstays of therapy for hypertension, but despite widespread availability of these approaches, many patients with hypertension are not adequately treated.

New imaging tool creates real-time, 3D images and maps of contractions during labor

Researchers funded by the National Institutes of Health have developed a new imaging tool, called electromyometrial imaging (EMMI), to create real-time, three-dimensional images and maps of contractions during labor.

New study focuses on genetic diversity of E. coli bacteria in hospitalized patients

The human intestine is an environment inhabited by many bacteria and other microorganisms collectively known as the gut microbiome, gut microbiota or intestinal flora. In most people, it contributes to wellness.

UK HealthCare provides a symphony of support for doctoral student after rare stroke

On a Sunday afternoon in April, Adiel Nájera’s world turned upside down. The 25-year-old University of Kentucky doctoral student knew something was wrong. Earlier that week, he experienced exhaustion, chest pains and trouble driving.

New project to validate a novel hydrogel for preventing scar tissue formation after heart attack

The European Union has awarded a European Consortium €4.5 million for the ELR-Scar project to validate a novel hydrogel biomaterial that will prevent scar tissue from forming in the heart following a heart attack.

Novel molecular mechanism responsible for common form of acquired hydrocephalus discovered

Mass General researchers have discovered a novel molecular mechanism responsible for the most common forms of acquired hydrocephalus, potentially opening the door to the first-ever nonsurgical treatment for a life-threatening disease that affects about a million Americans.

Quality improvement initiative successfully reduced urine culture testing for asymptomatic bacteriuria and catheter-associated asymptomatic bacteriuria

Researchers reported on the execution of two electronic healthcare record interventions for reducing urine culture ordering in asymptomatic bacteriuria and catheter-associated ASB in a low-resource safety net system.

New ablation technology successful at eliminating episodes of abnormal heart rhythms

A new ablation technology known as pulsed-field ablation was successful at eliminating episodes of abnormal heart rhythms for 12 months in up to two-thirds of patients, according to a study being presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology.

Immediate complete revascularization is not inferior to staged procedure for treating multi-vessel disease

In patients with multi-vessel heart disease who have had a heart attack, immediate treatment with stents in all diseased arteries was found to be as safe and effective at one year of follow-up as staged treatment, according to findings from the first large, randomized trial to address this question that is being presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology. In staged treatment, the blocked artery that caused the heart attack is treated with a stent immediately and other partially blocked arteries are treated in a second procedure up to six weeks later.

Transcatheter-based mitral valve repair safe and effective for nearly 9 out of 10 patients

The largest study to examine outcomes for patients treated outside a clinical trial setting with a minimally invasive procedure to repair a poorly functioning mitral valve in the heart found that the procedure was safe and resulted in a successful repair for nearly 9 out of 10 patients, researchers reported at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology. Patients whose procedure was successful were half as likely to die within one year compared with those in whom the procedure was unsuccessful.

Initial benefit of TAVR remains consistent over the first three years among patients at low surgical risk

The number of deaths and disabling strokes among patients at low surgical risk who were treated with transcatheter aortic valve replacement (TAVR) remained lower at three years, but not significantly lower, following the TAVR procedure compared with patients who received conventional surgical aortic valve replacement (SAVR), according to new data being presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology.

Using blood pressure medications after endovascular treatment for stroke may not be safe or effective

Using blood pressure medications to lower the top number of blood pressure reading (systolic blood pressure) may not be safe or effective among people who have an acute ischemic stroke and undergo a successful mechanical clot removal — endovascular therapy, according to a phase-2 late-breaking clinical trial presented today at the American Stroke Association's International Stroke Conference 2023.
