Accurate, fast soft-plaque measurement seen with coronary CTA

By Eric Barnes

Automated measurement of soft plaque in the heart using coronary CT angiography (CTA) was accurate compared to the gold-standard modality, intravascular ultrasound, and was far faster than manual methods, concluded a new report published online this month in Radiology.

Aortic root dilation in athletes requires close surveillance

By Reuters Health

NEW YORK (Reuters Health) - Aortic root dilation is uncommon in highly trained competitive athletes and is not likely to be caused by exercise training. Consequently, aortic root dilation in this population is probably pathologic and shouldn't be dismissed, according to findings published in the August 17 online issue of Circulation.

3D TEE bests 2D TEE in mitral regurgitation grading

By Erik L. Ridley

3D transesophageal echocardiography (TEE) is superior to 2D TEE for quantifying the severity of mitral regurgitation, according to researchers from Leiden University Medical Center in Leiden, the Netherlands.

Advanced CT may have role in noncalcified plaque assessment

By Eric Barnes

Advanced MDCT scanning may be ready to play an important role in assessing noncalcified coronary artery plaque, say German researchers, who used a 256-detector-row scanner and plaque-volume measurement software to compare interobserver variability in patients with different types of plaque.

Cardiac MRI shows how triathletes' hearts adapt

By Wayne Forrest and Eric Barnes

With the help of 1.5-tesla cardiac MRI, German researchers have found that the human heart adapts to triathlon training by developing greater muscle mass and wall thickness, as well as larger left atria and larger right and left ventricles, according to a study to be published in the October issue of Radiology.

Early graft patency rate lower with off-pump CABG

By Reuters Health

NEW YORK (Reuters Health), Aug 18 - Although studies suggest that off-pump coronary artery bypass graft (CABG) surgery is better than on-pump, a study from Portugal showed that off-pump patients had higher rates of early graft occlusion.

Cardiac resynchronization improves brain perfusion in heart failure

By Reuters Health

NEW YORK (Reuters Health), Aug 11 - When cardiac resynchronization improves left ventricular function in heart failure patients, it improves their cerebral blood flow as well, a small study has shown.

Enhanced reference standard boosts CTA accuracy

By Eric Barnes

Borrowing a technique from the virtual colonoscopy playbook, researchers from South Carolina and Germany found that coronary CT angiography (CTA) is better than previously thought compared to catheter-based coronary angiography -- in fact the two tests are essentially equivalent, they said.

Supersized CONFIRM trial tackles coronary CTA and mortality

By Eric Barnes

In a study that probes what may be the largest database of detailed coronary CT angiography (CTA) results assembled to date, New York City researchers found an integral association between coronary artery disease and mortality at coronary CTA in patients without known heart disease.
