Novel catheter technique for patching holes in the heart

A novel catheter technique for patching holes in the heart may make it possible for many patients to avoid surgery altogether and others to regain enough strength to safely undergo surgical repair at a later date, according to a study reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions.

Key findings on new-generation stent

New data reported at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), offered clues to the fate of a new-generation drug-eluting stent that is vying for a place in the treatment of coronary artery disease.

CT angiography can replace digital subtraction angiography

CT angiography (CTA) alone is an effective, noninvasive means to detect peripheral vascular disease, according to a study conducted by researchers at Charite Campus Benjamin Franklin in Berlin, Germany.

MDCT eliminates need for catheter angiography for aortic injury diagnosis

Contrast-enhanced 64-MDCT that definitively reveals acute trauma to the aorta does not need confirmation from invasive catheter angiography, which saves valuable time in treating patients in trauma centers, according to a new study by researchers from the Medical University of South Carolina in Charleston.

High intracoronary attenuation significantly improves diagnostic accuracy in 64-slice CT-CA of the coronary arteries

For the study, 170 patients with suspected coronary artery disease underwent CT-CA. The average vascular attenuation measured in the aortic root and in coronary arteries was used to divide the population into two groups of 85 patients each, one with low attenuations and one with high.

CT angiography has a nearly 100% detection rate in acute ruptured, cerebral aneurysms

CTA correctly detected the ruptured aneurysm in 170 cases when compared to intraoperative findings, Bijal Patel, MD, lead author of the study. Of the 22 cases where there was more than one aneurysm, CTA correctly identified the ones that were ruptured every time.

Efforts to standardize heart care are working

People who suffer a heart attack or severe chest pain today are much less likely to die, or to experience long-lasting effects, than their counterparts even a few years ago, according to a new international study in the May 3 issue of the Journal of the American Medical Association.

Embolic protection and platelet inhibition during renal artery stenting

High blood pressure is the most common chronic medical condition in the United States, and the most common identifiable cause is narrowing of a kidney artery, called renal artery stenosis.

Long-term safety of drug-eluting stents in off-label use

Research presented at the American College of Cardiology's Innovation in Intervention: i2 Summit 2007 in New Orleans, La, paints a picture of the "real world" use of drug-eluting stents and offers new insight into the connection between blood clotting, or thrombosis, in the stent - a dangerous complication - and adherence and responsiveness to anti-clotting medication.

Advances in clinical cardiology

Three studies being presented at the American College of Cardiology's Innovation in Intervention: i2 Summit 2007 in New Orleans, La., highlight the breadth of research propelling advances in clinical cardiology.

Sodium Bicarbonate vs. Sodium Chloride in persons undergoing coronary angiography

In patients undergoing cardiac catheterization, contrast dye injection can sometimes cause contrast-induced nephropathy (CIN), otherwise known as acute renal failure.

$Drug that mimics HDL does not reduce risk of death for heart attack patients with refractory shock$

Drug that mimics HDL does not reduce risk of death for heart attack patients with refractory shock

Patients with acute coronary syndromes (ACS), such as heart attack and recent-onset chest pain, remain at considerable risk of experiencing further serious cardiovascular problems despite improvements in care.

Adding estradiol to a polymer-free rapamycin-eluting stent is not associated with any measurable benefit

Patients admitted to the hospital with acute coronary syndromes (ACS) are often treated with a catheter-based procedure known as percutaneous coronary intervention (PCI), during which a stent is inserted into an occluded or narrowed coronary artery to restore blood flow to and from the heart.

Reconstituted HDL may have some benefit in coronary atherosclerosis

Preliminary research suggests that use of reconstituted HDL may have some benefit in coronary atherosclerosis, according to a JAMA study published online March 26.

Low levels of RANTES protein in the blood is a predictor of cardiac death

Researchers at SUNY Downstate Medical Center in Brooklyn have determined that low levels of a protein in the blood is a predictor of cardiac death in patients with coronary artery disease.

Magnetic resonance angiography of supraaortic arteries

A novel type of contrast-enhanced magnetic resonance (MR) angiography is highly accurate in identifying blockages in the arteries that carry blood to the brain, according to a study in the February issue of Radiology.

New study finds endurance athletes with ventricular arrhythmias have dysfunctional right ventricles

Some high-level athletes who take part in endurance sports can develop a rare but life-threatening condition called ventricular arrhythmia (VA) in which the heart beats at an abnormal rate and rhythm.

Advancing medical technology increases health-care costs

Advances in medical technology are a main factor driving the trend of increasing health care costs, and industry stakeholders agree that improved evaluation methods are needed to better measure the benefits and risks of new technologies and procedures in order to avoid misallocation of health care dollars.

Ultrasound targets angioplasty

World Congress of Cardiology 2006 - A simple technique - combining cardiac ultrasound with a heart muscle-stimulating drug - can identify the MI patients who would benefit most from angioplasty after thrombolysis, reports a study in Hot Line session II.

Endovascular repair of thoracic and abdominal aortic diseases as an alternative to open surgery in patients at high surgical risk

World Congress of Cardiology Report - Acute aortic syndromes, such as large thoracic and abdominal aortic aneurysms with impending rupture, complicated acute type B dissections, traumatic rupture of thoracic aorta, still represent life-threatening conditions.
