ASIR coronary CTA technique reduces radiation dose by 27%

A new low-dose coronary computed tomography angiography (CTA) technique called adaptive statistical iterative reconstruction (ASIR) can reduce the radiation dose associated with coronary CTA by 27 percent, according to a study in the September issue of the American Journal of Roentgenology (www.ajronline.org). Coronary CTA is a common heart imaging test that helps determine if fatty or calcium deposits have narrowed a patient's coronary arteries.

Drug-eluting stents improve long-term clinical outcome for patients undergoing angioplasty

Researchers at the Rabin Medical Center in Israel have determined that the use of drug-eluting stents (DES) improves the long-term clinical outcome for patients undergoing percutaneous coronary intervention (PCI), commonly known as angioplasty. Results of this study appear in the September issue of Catheterization and Cardiovascular Interventions, a journal published by Wiley-Blackwell on behalf of The Society for Cardiovascular Angiography and Interventions.

BioSTAR biodegradable implant achieves comparable closure rates to Amplatzer ASO

A novel study by Canadian physicians reported that the BioSTARTM biodegradable implant achieved comparable closure rates to the Amplatzer Septal OccluderTM (ASO) in children with atrial septal defect (ASD). The BioSTAR device displayed successful outcomes, while avoiding issues associated with implants containing substantial amounts of metal.

ISHLT issues first international consensus formulation of standardized nomenclature for CAV

Cardiac allograft vasculopathy (CAV), the major limitation to long term survival after heart transplantation, occurs when blood vessels in a transplanted heart progressively narrow and lead to dysfunction of the heart muscle or sudden death. Ascertaining benefit from appropriate treatment for this condition has been hampered in part because of the lack of a standard nomenclature.

CT angiography not necessary in patients suspected with pulmonary embolism

A new study suggests that computed tomography (CT) angiography might be unnecessary in many patients suspected of having pulmonary embolism (PE), based on the results of risk assessment analysis. PE risk assessment could help reduce radiation exposure and costs associated with CT angiography. The results of the study appear in the online edition and August print issue of the journal Radiology.
