Imaging

 - right wrong decision

Hospitals that want to reduce inappropriate PCI rates may want to look beyond the cath lab for opportunities. A study published online Aug. 25 in JAMA Internal Medicine identified diagnostic coronary angiography in asymptomatic patients as a red flag for PCI overuse.

 

 - doctors talking

Transthoracic echocardiogram use has been on the rise, but is it always appropriate? Not always, but a physician-centered intervention aimed at improving trainees’ adherence to appropriate use criteria appeared to increase appropriate and decrease inappropriate testing.

 - ecg, heart, electrophysiology

Delayed-enhancement cardiac MR (DE-CMR) one day may be used to guide reablation procedures to treat atrial fibrillation if results from a feasibility and proof-of-concept study pan out. The study showed DE-CMR accurately identified and localized gaps in patients being reablated because of recurrences.

 - radiation dose

Cardiologists at the Cleveland Clinic reduced radiation doses by 22 percent for diagnostic catheterizations and by 32 percent for PCI by leveraging new imaging technology, according to results published online Aug. 5 in Circulation: Cardiovascular Interventions

 - heart

A new protocol nuclear cardiologists could use to improve identification of coronary plaques involves decreasing F-18 FDG myocardial uptake to reveal more coronary detail in cardiac PET/CT. A high-fat meal prior to fasting seems to do the trick, according to a study published July 31 in the Journal of Nuclear Medicine.
