What's the best tool for post-TAVR imaging?
In patients who have undergone transcatheter aortic valve replacement, cardiac magnetic resonance imaging may be better than echocardiography for measuring aortic regurgitation, according to a report in the journal Heart. The study found that echo evaluation tended to underestimate aortic regurgitation severity, with MR better able to identify moderate cases. Both modalities were able to rule out severe regurgitation.

CCTA flags CAD in survivors of childhood Hodgkin lymphoma
Coronary artery disease was discovered in 39% of adult survivors of childhood Hodgkin lymphoma through the use of coronary CT angiography, according to a study by St. Jude Children's Research Hospital. The study's 31 survivors had a median age of 40 and were a median of 24 years post-diagnosis. "Coronary computed tomography angiography may offer an effective noninvasive tool for the management of at-risk cancer survivors, permitting the identification of those who might benefit from lifestyle and/or medication interventions and those for whom lower levels of monitoring may be appropriate," said Dr. Daniel Mulrooney.

Physician networks not a priority for insurance regulators
State insurance regulators will focus more on ensuring health plan quality than on the makeup of physician networks, according to Wisconsin insurance commissioner Ted Nickel, who leads a National Association of Insurance Commissioners task force. The task force is working on a new rule for states to use to regulate physician networks in insurance plans that are part of the Affordable Care Act's health insurance exchanges.
