The variable fluorescence attenuation of blood has been a hindrance to near-infrared fluorescence (NIRF) measurements in cardiovascular imaging. Fortunately, researchers have devised an innovative correction method in which the guidewire (GW) is coated with the fluorescent agent (ICG) and used as a reference standard in each frame, leading to a much higher accuracy.

New technique improves accuracy of near-infrared fluorescence imaging

NIRF imaging could help interventional cardiologists personalize care in the cath lab, but a key engineering issue needed to be solved first.

Abbott’s FreeStyle Libre 3 integrated continuous glucose monitoring (iCGM) system

Abbott’s newest glucose monitoring device gains FDA clearance

The news comes after Abbott had to recall more than 4.2 million older glucose monitoring systems due to issues with batteries overheating. 

x-ray dosimetry capsule monitors radiation dose during radiotherapy

Swallowable capsule monitors radiation dose in real-time during radiotherapy

Coming in at a diameter of 5 mm and thickness of 0.2 mm, the X-ray dosimeter measures radiation dose up to five times more accurately than standard methods. 

Marielle Scherrer Crosbie and Tomas Neilan explain the STOP-CA trial and how statins can help prevent cardiotoxicity from anthracycline chemo agents.

Statins may help prevent anthracycline cardiotoxicity in chemotherapy

The STOP-CA trial showed that statins can help chemotherapy patients avoid potential side effects related to anthracycline agents. Co-principal investigators Marielle Scherrer-Crosbie, MD, and Tomas Neilan, MD, discussed the details of that trial at ACC.23.

Clopidogrel linked to better long-term outcomes than aspirin in PCI patients with and without diabetes

Clopidogrel is especially effective at limiting major adverse cardiovascular events among PCI patients with diabetes, researchers found. 

Imaging required to monitor effects of new Alzheimer's drug could inhibit its uptake

Leqembi can cause amyloid-related imaging abnormalities (ARIA), which must be assessed on imaging.

The LuX-Valve Plus transcatheter tricuspid valve replacement (TTVR) device

Cardiologists make history, perform TTVR with new-look valve for first time in U.S.

The new valve was placed inside the damaged valve via a catheter that is inserted through a small incision in the patient's neck. 

SCAI blasts Medicare payment cuts to cardiology, asks members to take action

The group hopes its members can increase congressional support of a new bill introduced in the House.
