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.

Weight loss helps older AF patients slim down, but does not ease symptoms

An 8-month low-calorie diet plus behavioral support helped older adults with overweight or obesity and persistent atrial fibrillation lose weight safely, with no intervention-related serious adverse events. However, the LOSE-AF trial found no meaningful improvement in AF symptoms, rhythm control, AF burden, cardiac remodeling, or further AF procedure rates compared with usual care.

Study supports reusable catheters as safe and cost-effective alternatives

Reusable catheters are just as safe for patients as single-use ones and do not increase the risk of urinary tract infections, a new study has found.

Wastewater tracking catches hospital fungus before patients show symptoms

A new UNLV-led wastewater surveillance study brings scientists one step closer in the global race to detect and deter skyrocketing cases of a potentially deadly drug-resistant fungus that puts hospital patients at risk of serious blood, heart, or brain infections.

Noninvasive brain monitoring reveals hidden oxygen deprivation in ICU patients

In neurological intensive care, it is quickly learned that the brain cannot wait. As the most sensitive organ in the human body, it can sustain irreversible damage after just a few minutes of severe hypoxia.

Ablation can lead to better outcomes for patients with advanced atrial fibrillation

A minimally invasive heart procedure may be a better first-line treatment than medication for people living with advanced forms of atrial fibrillation, according to a major international clinical trial led by researchers at the University of British Columbia.

Email alerts boost valve replacement rates in older patients with aortic stenosis

New data finds older patients with severe aortic stenosis (AS) were more likely to receive aortic valve replacement (AVR) and survive when clinicians received automated email notifications with abnormal heart ultrasound results detecting AS.

Blood return system dramatically reduces blood loss during pulmonary thrombectomy

The first comparative analysis from the ENGULF (A Safety and Feasibility Single-Arm Study of a Novel Catheter Thrombectomy Device For the Treatment of Pulmonary Embolism) trial shows that using blood return during continuous aspiration thrombectomy dramatically reduces blood loss by 97%, while maintaining hemodynamic efficacy and improving procedural efficiency.

Newborns carry antibiotic resistance genes within first hours of life

Antibiotic resistance genes (ARGs) – segments of DNA that help bacteria survive the effects of antibiotics – can be present in newborns within the first hours of life, according to research presented at ESCMID Global 2026.

Rural Nebraska dialysis unit closes despite the state’s $219M in rural health funding

The sun was just warming the horizon as Mark Pieper left his house near his cattle ranch on a crisp February morning.

Minimally-invasive stenting effectively treats painful post-thrombotic syndrome

A major multi-site clinical trial co-led by researchers at Washington University School of Medicine in St. Louis has shown that post-thrombotic syndrome - a common and often painful complication suffered by many people who have experienced blockages of major veins due to blood clots - can be effectively treated with a minimally invasive procedure.

Study reveals brain mechanisms behind post-stroke urinary incontinence

A new USC-led study using functional magnetic resonance imaging (fMRI) reveals the neural mechanisms that contribute to urinary incontinence, a common condition affecting stroke survivors that has a significant impact on their quality of life.

New guidelines and follow-up standards improve pulmonary embolism outcomes

Pulmonary embolism, or PE, is a serious and sometimes life-threatening condition that occurs when a blood clot travels to the lungs and blocks blood flow.

Study explores how a powerful antiseptic affects bacteria in hospital environments

Just because a topical antiseptic is swabbed on the skin doesn't mean it stays on the skin.

Digital twin hearts improve outcomes in arrhythmia ablation procedures

Working with "digital twins" of patients' hearts, doctors improved cardiac ablation outcomes for patients with life-threatening arrythmias.

Dual imaging reveals hidden causes of heart attacks without blockages

When Ashley Perlow felt a sharp pain shoot across her chest and into both wrists, she didn't think it could be a heart attack. She was 36, a new mom, and otherwise healthy.

Study links atrial fibrillation to poorer brain clearance and cognitive decline

Researchers found that people with atrial fibrillation had lower MRI-based glymphatic activity and poorer cognitive performance than healthy controls, with the greatest impairment seen in non-paroxysmal AF. In patients who underwent catheter ablation, glymphatic activity improved after sinus rhythm was restored, suggesting a possible link between heart rhythm, brain waste clearance, and cognition.

Deferring PCI before TAVR shows comparable outcomes in elderly patients

Older patients with coronary artery disease scheduled for transcatheter aortic valve replacement (TAVR) had comparable outcomes regardless of whether they underwent percutaneous coronary intervention (PCI) before TAVR, according to findings from the PRO-TAVI study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Transcatheter valve-in-valve procedure improves short-term outcomes in high-risk patients

In patients with a poorly functioning bioprosthetic mitral valve in the heart, a minimally invasive procedure to insert a new valve was associated with a lower rate of death or disabling stroke within one year, compared with patients who underwent standard repeat mitral valve replacement surgery, according to a study presented at the American College of Cardiology's Annual Scientific Session (ACC.26).

Minimally invasive valve repair lowers hospitalizations in heart failure patients

At two years of follow-up, patients with a poorly functioning tricuspid valve in the heart who received optimal medical therapy plus a minimally invasive procedure using a clip to repair the valve were significantly less likely to die, have a heart attack or stroke and 40% less likely to be hospitalized for heart failure compared with similar patients who were randomly assigned to optimal medical therapy alone.

Novel vFFR method performs similar to invasive coronary assessment

A novel, minimally invasive method of determining whether fatty deposits in a coronary artery are restricting blood flow to a patient's heart performed similarly to the standard, more-invasive procedure in a large multi-country European randomized trial presented at the American College of Cardiology's Annual Scientific Session (ACC.26).
