 - patient

Performing immediate coronary angiography following cardiac arrest led to improvements in survival among patients with and without STEMI, according to a retrospective registry analysis.

 - Neon Heart

And the winner is … optical coherence tomography (OCT). A head-to-head comparison of three imaging modalities found that OCT was the sole independent predictor of periprocedural MI in patients with coronary artery disease.

 - Chest Pain

After 40 months of follow-up, patients with acute chest pain had similar outcomes and resource utilization whether they were randomized to undergo coronary computed tomography angiography (CCTA) or myocardial perfusion imaging (MPI) at an inner city medical center. The primary outcome of cardiac catheterizations not leading to revascularization was similar in the groups.

 - child

Researchers from Children’s Hospital Colorado have had success using a fused fluoroscopic and echocardiographic imaging system in children with congenital heart disease, a patient population that typically has not used the system.

 - heart

At the American Society of Echocardiography (ASE) annual scientific sessions, the use of point-of-care echocardiography is among the major topics of discussion. The conference takes place from June 12 to June 16 at the Hynes Convention Center in Boston.

MRIs and ICDs can mix, at least if MR imaging is with a 1.5 Tesla machine and the implantable cardioverter-defibrillator system is the one tested in a late-breaking clinical trial presented May 14 at the Heart Rhythm Society’s scientific session in Boston.

RV longitudinal strain helps detect myocardial fibrosis in HF patients

An analysis of patients with severe systolic heart failure found that right ventricular free wall longitudinal strain was the most accurate diagnostic tool for detecting myocardial fibrosis. The patients’ right ventricles were significantly enlarged when their systolic function was reduced.

CMR may help predict stroke risk in patients with AF

Based on cardiac magnetic resonance (CMR) measurements in patients with atrial fibrillation, there was an association between left atrial reservoir dysfunction and a prior history of stroke or transient ischemic attack, according to a retrospective study.

Intermittent screening detects 33% more cases of atrial fibrillation

A screening program using intermittent electrocardiogram (ECG) recordings detected previously unknown atrial fibrillation in 3 percent of the 75- and 76-year-old participants, most of whom then initiated treatments.

Coronary CT angiography is cost-effective for patients with stable chest pain

For patients with stable chest pain, utilizing coronary CT angiography before cardiac stress imaging was cost-effective, according to a microsimulation model.

3D CMR shines as diagnostic tool for detecting CAD

Whole-heart 3D myocardial perfusion cardiac MR (CMR) accurately detected coronary artery disease (CAD) in a study that used fractional flow reserve as a reference, making CMR a possible contender to techniques that are invasive and expose patients to ionizing radiation.

High-efficiency SPECT system works, even in morbidly obese

A high-efficiency SPECT system provided high quality and diagnostically accurate images for detecting coronary artery disease in obese patients, even morbidly obese patients, researchers reported in the April issue of the Journal of Nuclear Cardiology.

The FDA issued a pair of Class II recalls on MR imaging systems. The unrelated announcements affect some devices made by GE Healthcare and Siemens.

MRI beats echo for accuracy of mitral regurgitation assessment

Echocardiography may be cost-effective and widely available, but a comparison of echo and MRI found only a modest accord in assessing mitral regurgitation. And between them, MRI had greater accuracy in evaluating regurgitation volume.

ACC.15: CTA holds slight edge despite a draw on outcomes

Coronary CT angiography (CTA) and functional testing came out on more or less equal footing for diagnosing coronary artery disease (CAD) in symptomatic patients, according to results from the PROMISE trial presented March 14 at the American College of Cardiology scientific session. But CTA pulled ahead in other ways.

ACC.15: Get to know GE Healthcare

In isolation, AUCs for diagnostic caths may miss mark

Appropriate use criteria (AUC) can be useful for decision-making, but is it a hard and fast answer? A prospective study found approximately one-third of patients diagnosed with blocked arteries would have been deemed inappropriate for angiography with 2012 AUCs.

Coronary CT angiography may outperform functional imaging

Noninvasive anatomic imaging appears to be superior in detecting significant coronary artery disease over functional testing, maybe. A study suggests that CT angiography is more accurate, but it may have been missing key data.

HEART tool reduces cardiac testing in patients with acute chest pain

HEART might offer a way to discharge low-risk chest pain patients early and reduce objective cardiac testing, according to findings published March 3. While early discharge with no increase in major adverse events would be a coup, some are not convinced that reducing cardiac testing rates overall is feasible.

AUC may influence some, not all, forms of cardiac imaging

Imaging appropriate use criteria (AUC) should reduce the number of less-appropriate tests, however, researchers have found that in some cases, the gray area may hold greater sway in how frequently rarely appropriate tests are performed.

Building awareness about radiation, one message at a time

“It has to be hit home on a regular basis.” “It” is the need to be aware of radiation exposure in the cath lab, and the message bearer in this case was Charles E. Chambers, MD, an interventional cardiologist who devotes time and energy promoting radiation safety.

Researchers evaluating the relative value of long-term forecasts for risk among low-risk patients without coronary artery disease (CAD) found that coronary artery calcium scores derived from CT scans may hold the biggest prediction bang.
