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.

Women with heart attacks benefit from stenting

Female heart attack patients undergoing angioplasty have a higher risk of death than men, but stenting may improve their outcomes, according to a study reported in Circulation: Journal of the American Heart Association.

Cryoablation may be safer alternative for stopping abnormal electrical patterns

Freezing abnormal electrical pathways in the hearts of young patients may be a safer alternative to zapping them with powerful radiofrequency probes in order to treat tachycardias and other arrhythmias, according to a new study in the April 5, 2005, issue of the Journal of the American College of Cardiology.

Gene therapy shows effect in heart patients

The first double-blind, placebo-controlled randomized trial of VEGF gene injections into the heart muscle of patients with coronary artery disease with the intention of spurring growth of new blood vessels showed significant effects on heart wall motion, although blood flow was not significantly better in treated patients, according to a new study in the April 5, 2005, issue of the Journal of the American College of Cardiology.

Chemoembolization, first-line treatment for liver cancer

New research by Jeff Geschwind, M.D., director of interventional radiology and associate professor at Johns Hopkins University School of Medicine, has shown that liver cancer patients, most of whom have inoperable tumours, could benefit from chemoembolization, a nonsurgical treatment option that delivers a high-dose of chemotherapy to the tumour while decreasing blood flow through the arteries feeding the tumour, known as embolization.

Study shows connection of varicose veins to chronic pelvic pain

Research presented today at the Society of Interventional Radiology's 30th Annual Scientific Meeting found that 16 percent of women with varicose veins in their legs simultaneously had ovarian varicose veins -- a common but often under-diagnosed cause of chronic pelvic pain.

Uterine fibroid embolization is effective treatment for uterine fibroids

Data presented today at the 30th Annual Scientific Meeting of the Society of Interventional Radiology found that the nonsurgical embolization treatment for uterine fibroids had a 73 percent success rate at five years.

Urine actually helps a particular yeast stick to cells along the urinary tract

The finding might offer a new way to prevent or treat certain yeast and fungal infections, and the researchers' work also provides an unexpected new role for some proteins already known to help hungry yeast live longer.

Optical coherence tomography (OCT) can successfully identify the characteristics of coronary plaques

A catheter-based imaging technology called optical coherence tomography (OCT) can successfully identify the characteristics of coronary plaques in patients with various cardiac symptoms. The report from researchers at Massachusetts General Hospital (MGH) will appear in the journal Circulation.

New form of technology to treat cardiac arrhythmias

Virginia Commonwealth University Medical Center physicians are among the first in the country to use a new form of technology to treat distant, malfunctioning areas inside the heart that cause irregular heartbeats, or cardiac arrhythmias.

Treatment of cardiac lesions without anaesthesic

Navarre University Hospital has introduced a novel technique for the treatment of congenital heart defects and involving the percutaneous closure of the patent foramen ovale (PFO) with monitoring through intracavernous ecography.

Heart valve transplant through leg quicker and benefits high risk cases

An experimental procedure marks the launch of a research study approved by the Food and Drug Administration in January. The breakthrough technology could save the lives of thousands of people with heart valve disease who have no other treatment options. In a new clinical trial the first U.S. patient has received a heart valve implant without open-heart surgery.

Pet scanning could cut use of angiograms and bypass surgery, as well as patient costs

Using positron emission tomography (PET) scanning rather than other types of imaging as the first tool to diagnose heart-vessel blockages is more accurate, less invasive and saves dollars, a study by a University at Buffalo team has shown.

Large hole in boy's liver repaired using innovative catheterization procedure

Through an innovative catheterization procedure, a pediatric cardiologist at Texas Children's Heart Center in Houston repaired a severe liver condition in a 14-year-old male.

Drug eluting stents as effective as vascular brachytherapy in preventing restenosis

After angioplasty is performed to widen clogged arteries, surgeons frequently use tiny wire-mesh tubes called stents to keep blood vessels open. But despite stenting, scar tissue can form to create new blockages -- a process called in-stent restenosis (ISR).

Artery clearing device does not provide benefit for heart attack patients undergoing artery-opening interventions

Use of a device and system to clear dislodged "debris" during percutaneous interventions to open a blocked artery following a heart attack does not appear to be clinically beneficial, according to a study in the March 2 issue of JAMA.

Nonsurgical microspheres an option for liver cancer patients

A study in February’s Journal of Vascular and Interventional Radiology found that patients undergoing liver cancer treatment with Theraspheres?, radioactive microspheres containing Yittrium-90, can tolerate a 150 Gy single dose or 268 Gy repeated dose without risk of radiation-induced liver disease.

Heart repair linked to migraine relief

Migraine headache patients reported the painful attacks eased or even vanished after they underwent procedures to close abnormalities that allow blood to flow between the atria of their hearts, according to the results of two new studies in the current issue of the Journal of the American College of Cardiology.

Risks of obesity in children with kidney transplants

Obese children who get kidney transplants tend to be younger, shorter and on dialysis longer than their leaner peers, according to a study in the February issue of the journal Pediatrics.

Gene therapy for heart patients with chest pains who do not benefit from other treatments

Individuals with moderate to severe chest pains (angina) who have not found relief from medication may benefit from a new gene therapy approach being used by cardiologists at Rush University Medical Center to grow new blood vessels in the heart.
