Angioplasty News and Research

RSS

In angioplasty procedures, a balloon is fed through a catheter and used to prop open an artery that has become narrowed or blocked. In cases where stenting is appropriate, a stent mounted on a balloon is inserted and inflation of the balloon expands the stent against the blocked artery wall to hold the vessel open. The balloon is then deflated and the catheter is withdrawn. Stent treatment of arteries holds them open and improves blood flow to the heart. In cases where post-dilatation is needed, a high-pressure balloon is inflated inside a stent to help better place the stent against the vessel wall.

Increased screening may better predict those at higher risk for heart disease

Bivalirudin improves net clinical outcomes and increases survival in heart attack patients

A study led by Gregg W. Stone, M.D., professor of medicine at Columbia University Medical Center/NewYork-Presbyterian and chairman of the Cardiovascular Research Foundation, has shown that heart attack patients who were administered the direct thrombin inhibitor bivalirudin during primary angioplasty had a reduced rate of adverse clinical events, a lower rate of major bleeding, and a lower mortality rate than those who were treated with a regimen of heparin and glycoprotein IIb/IIIa inhibitors (GPI).

Beta blockers after surgery more risky than beneficial

The results of new research has shown that patients given high doses of beta blocker drugs following non-cardiac surgery were more likely to have a stroke or die. However they were less likely to suffer a heart attack.

Drug-releasing stent shows promise for improving outcomes in patients with coronary artery disease

For patients who underwent angioplasty to open narrowed coronary arteries, the use of stents releasing the drug everolimus reduced the rate of renarrowing of the arteries and significantly reduced the risk of major cardiac events, compared to the widely-used paclitaxel-releasing stents, according to a study in the April 23/30 issue of JAMA, the Journal of the American Medical Association.

Patients arriving at hospitals in daytime hours get faster, better care compared to off hours

Patients hospitalized with heart attacks tend to get faster and more comprehensive care if they arrive during daytime hours, according to a report in Circulation: Journal of the American Heart Association.

Angina drug ranolazine potentially useful against heart rhythm disorders

A recently approved angina drug may also represent a powerful new treatment for a rare hereditary syndrome that places teens at risk for sudden cardiac death, according to research presented on April 1st at the 57th Annual Scientific Sessions of the American College of Cardiology (ACC) in Chicago.

Angioplasty and stenting for renal artery lesions

The largest-ever randomized study to evaluate the effectiveness of catheter-based interventions in patients with narrowing of the renal artery has shown that angioplasty and stenting offer no benefit over medical therapy.

Special catheter that clears debris from artery helps blood flow in percutaneous coronary intervention

Use of a special catheter that sucks out, or aspirates, bits of plaque and blood clot that break loose during percutaneous coronary intervention (PCI) significantly enhances blood flow deep in the heart muscle in patients who are experiencing a heart attack, according to a recently published study.

Comparison of anticoagulants for angioplasty show similar outcomes

In a comparison of anticoagulants and stents for use with angioplasty following a heart attack, the anticoagulants abciximab and tirofiban had similar outcomes for some cardiac measures within 90 minutes after the procedure, while patients who received stents that released the drug sirolimus had a lower risk of major adverse cardiac events within 8 months than patients who received uncoated stents, according to a JAMA study being released early online March 30 to coincide with its presentation at the annual conference of the American College of Cardiology.

Uterine fibroid embolization effective in cases where focused ultrasound failed

Uterine fibroid embolization (UFE), a minimally invasive interventional radiology treatment for uterine fibroids, provides significant relief of symptoms for women whose focused ultrasound (FUS) treatment failed, according to a study released during the Society of Interventional Radiology's 33rd Annual Scientific Meeting in Washington, D.C. Primary care physicians and gynecologists can feel confident in informing patients that a failed FUS treatment does not require subsequent gynecological surgery.

New interventional radiology treatment shows promise for complications from bone marrow, stem cell tranplants

The standard treatment to treat graft-versus-host disease (GVHD) after bone marrow or cord blood transplant is intravenous (IV) steroids that alter the immune response; however, it is not always effective and failure results in very high mortality.

Most women unaware of uterine fibroid embolization

A study presented at the Society of Interventional Radiology's 33rd Annual Scientific Meeting shows of 105 patients in the Atlanta metro area, only 18 percent of the women who saw a private practice gynecologist were told about uterine fibroid embolization (UFE), a minimally invasive treatment for uterine fibroids provided by interventional radiologists.
