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.

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.

Catheter ablation to treat supraventricular tachycardia (SVT) is not detrimental to patients

This data refutes previous evidence which suggested a high incidence of injury to a patient's cardiac nerves, possibly resulting in accelerated heart rates following the procedure.

Invasive procedures do not necessarily improve survival for heart patients

Invasive procedures, often given to patients as soon as they are admitted to hospital with a life-threatening heart condition, do not necessarily improve survival, finds a study published on bmj.com today.

Catheter ablation safe for patients

A recent study published in Pacing and Clinical Electrophysiology (PACE) determined that the use of catheter ablation to treat supraventricular tachycardia (SVT) is not detrimental to patients.

Hypnosis helps kids undergoing difficult procedure called voiding cystourethography

Elaine Miller desperately wanted to find a way to help her daughter, Hannah, endure an awkward and painful medical examination in which doctors insert a catheter into her bladder, inject a dye and ask her to urinate while being X-rayed.

Babies who do not sleep on their stomachs fail to learn behaviors that may lessen their risk SIDS

Babies who never sleep on their stomachs don't learn behaviors that may lessen their risk of sudden infant death syndrome (SIDS), researchers at Washington University School of Medicine in St. Louis have found. Even so, the researchers caution that infants should always be placed on their backs to sleep.
