New imaging recommendations for prosthetic heart valve assessment

Recommendations for the assessment of prosthetic heart valves using multimodality imaging including echochardiography and cardiac CT have been published in European Heart Journal: Cardiovascular Imaging.

Plaque-fighting nanoparticles could help prevent heart attacks and strokes

Scientists have created a new type of nanoparticle capable of not only imaging harmful plague inside arteries using MRI but simultaneously treating it as well. The findings were announced at the National Meeting and Exposition of the American Chemical Society.

ACC, ACR release imaging guidelines for ED patients with chest pain

The American College of Cardiology (ACC) and American College of Radiology (ACR) released guidelines on Jan. 22 regarding the appropriate use of imaging for patients who come to the emergency department with chest pain.

Emergency CCTA: As good as traditional testing and no more demanding of resources

Three major trials have already established the 30-day clinical and economic soundness of ordering coronary CT angiography in evaluations of patients who show up in the emergency department complaining of chest pain. A new study shows the CCTA pathway to be similarly strong at the 12-month mark. 

Myocardial perfusion imaging has low yield for detecting ischemia in AF patients

An analysis of patients with atrial fibrillation at the Cleveland Clinic found the yield of using myocardial perfusion imaging for detecting ischemia was low and did not significantly increase with increasing cardiovascular risk. Ischemia was not associated with mortality, either.

Noninvasive stress testing varies considerably following PCIs at VA hospitals

An analysis of veterans undergoing PCIs at Veterans Affairs (VA) hospitals across the U.S. found the rates of noninvasive stress testing following the procedures varied considerably. The frequency of stress testing was not significantly associated with all-cause mortality or MI.

SNMMI: Scanning for cardiac amyloid could help predict heart attacks

While amyloid imaging is typically discussed with regard to diagnosing Alzheimer’s disease, a team of French researchers, presenting at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2015 annual meeting, have found that amyloid scans of the heart can predict major cardiac events.

HRS.15: MRI doesn’t compromise ICD’s safety, effectiveness

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.

The multi-pronged approach to reducing MPI dose

The use of myocardial perfusion imaging (MPI) has spiked over the past four decades and along with it individual patient dose. A comprehensive effort to reduce that dose could reduce unnecessary procedures and reduce the risk of downstream cancers, according to a meta-analysis published in the April issue of the Journal of Nuclear Medicine.

Quantifying cardiac PET: MFR may be more consistent than MBF

There are a few different quantitative techniques used to measure myocardial blood flow (MBF) and myocardial flow reserve (MFR), both of which have been shown to provide useful information in managing cardiovascular disease. However, MFR measurements appear to be less affected by variables of quantitation when using different arterial input functions and extraction models, according to a comparison study published today in the Journal of Nuclear Medicine.
