FDA warns against use of unauthorized smartwatch, smart ring devices to measure blood glucose levels

Any devices that claim to make blood glucose measurements without piercing the user's skin are associated with a heightened risk of error, the agency said. 

An aortic vascular surgery case being performed with the Philips LumiGuide FORS system. The light-based technology enables catheter navigation and the ability to see the catheters in multiple views with out the need for X-ray imaging in the cath lab.

Philips launches new light-based, radiation-free cath lab imaging system

LumiGuide uses fiber optic realShape (FORS) technology, where light is reflected along an optical fiber inside a guidewire to generate 3D, high-resolution, color images of devices inside a patient’s body

Alain Cribier, MD, a veteran interventional cardiologist known for performing the very first transcatheter aortic valve replacement (TAVR), died on Feb. 16. He was 79 years old.

Cardiology pioneer, known for performing world’s first TAVR, remembered as a ‘true visionary’

Alain Cribier, MD, a veteran interventional cardiologist out of France, died at the age of 79. The procedure he helped put on the map is arguably cardiology's most significant breakthrough in the last several decades. 

Insurance plans still denying more claims for PCSK9 inhibitors than other cardiovascular drugs

Despite an expanded indication from the FDA and lower prices, patient access to these cholesterol-lowering medications remains a significant issue.

Multiple factors can interfere with pulse oximetry accuracy including skin pigmentation. Multiple studies have shown the inaccuracy of current pulse oximeters in patients with darker skin tones than whites, often over estimating their oxygenation when in fact they are hypoxic.

Inaccurate pulse oximeter readings impact Black heart failure patients and FDA plans to address this

Black patients are already less likely to receive LVADs or transplants compared to whites, and these inaccurate readings can further widen the disparities.

The Reprieve System using intelligent software and automation to manage diuretic dosing and fluid replacement for patients with acute decompensated heart failure (ADHF).

Heart failure startup emerges with $42 million in financing for its intelligent fluid management system

Reprieve Cardiovascular emerged from stealth mode this week with sizable financial backing and some big name board members to advance development for its intelligent, automated diuretic and fluid management system for heart failure.

An Illinois appellate judge upheld a pervious trial victory that cleared and central Illinois cardiologist Amit Dande, MD, and Prairie Cardiovascular Consults LLP of alleged misdiagnosis of the severity of a patient's heart condition that led to his death prior to a schedule percutaneous coronary intervention (PCI).

Illinois cardiologist not held responsible for patient's death while waiting for angiogram

A judge upheld a previous trial victory that cleared Prairie Cardiovascular Consults of alleged mishandling of a patient and not fully understanding the severity of the heart condition prior to their death.

Examples of photon-counting coronary angiography showing how clarity improves as the thickness of the image is reduced. Top: 60-year-old female, with noncalcified plaque (arrowheads) and coronary stenosis (inset images). The reduced section thickness did not affect assessment in this patient. Bottom: 56-year-old female with calcified plaque (arrowheads) and coronary stenosis. The reduced section thickness leads to less calcium blooming and therefore a less severe percentage of stenosis.

Coronary artery disease classification improved with photon-counting CT

After a photon-counting CT, 54% of patients had their coronary artery disease classification downgraded.

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.
