This channel newsfeed includes clinical content on treating patients or the clinical implications in a variety of cardiac subspecialties and disease states. The channel includes news on cardiac surgery, interventional cardiology, heart failure, electrophysiology, hypertension, structural heart disease, use of pharmaceuticals, and COVID-19.

A common word may be giving heart patients the wrong idea
Cardiologists often use the word “stable” when describing a heart failure patient who is recovering or showing signs of improvement. That word, however, could be giving patients a false sense of security—and it could even do harm to their long-term health.
Q&A: Cardiologist reviews key trends in pediatric electrophysiology for 2026 and beyond
Pediatric electrophysiology is an invaluable part of any healthcare system, and its importance is only growing as technologies continue to evolve. We spoke to Nicholas Von Bergen, MD, to learn more about where the specialty is headed in the years ahead.
Is IVL safe for patients with diabetes?
New two-year data confirm that the IVL technology developed by Shockwave Medical can be used to treat diabetic patients who require PCI.
CPT code updates in 2026 will change how interventional cardiologists get paid
A variety of CPT code changes take effect in 2026, and many of them will make a direct impact on interventional cardiology. Arnold Seto, MD, spoke to Cardiovascular Business about these updates for a new video interview.
M-TEER still beneficial for high-risk patients with smaller mitral valve areas
Mitral valve surgery can be especially challenging when patients present with a small mitral valve area. When it comes to M-TEER, however, treatment still appears to be both safe and effective.

AI detects hypertension in voice recordings

A machine learning-powered smartphone app was trained to detect hundreds of biomarkers in the human voice, using even the tiniest detail to anticipate when patients may present with symptoms of hypertension.

More and more radiation therapy jobs going unfilled

As part of efforts to address staffing shortages, the American Society of Radiologic Technologists is holding a virtual career fair focused on radiation therapy jobs on Sept. 26.

Watchdog group, fearful of fraud, wants more oversight for remote patient monitoring

Cardiologists and other physicians may soon need to provide much more information when ordering remote patient monitoring for Medicare patients.

Space travel disrupts normal rhythm in heart cells

Heart tissue samples that spent 30 days at the International Space Station appear to have been weakened by the low gravity conditions in space. This finding has implications for the heart health of astronauts.

Stroke specialists raise another $50M thanks to late investment from Novo Holdings

California-based Route 92 Medical previously announced a funding round worth more than $31 million in November. Now, however, a massive addition from Novo Holdings makes the round worth closer to $82 million.

MRI study pinpoints neural roots of lingering fatigue post-COVID infection

Some of the findings observed have also been reported in patients who have multiple sclerosis, “which could suggest partially shared pathophysiological substrates of fatigue symptoms,” researchers indicated.

A majority of medical devices involved in Class I recalls were never required by the U.S. Food and Drug Administration (FDA) to undergo premarket or postmarket clinical testing, according to new research published in Annals of Internal Medicine.[1]

Most recalled cardiovascular devices gained FDA approval with little to no clinical evidence

Why are so many cardiovascular devices involved in Class I recalls? One possible reason could be the large number of devices hitting the market without undergoing much premarket clinical testing.

Researchers have found that homemade play-putty can effectively capture electrocardiogram (ECG) signals at a level comparable to commercially available electrodes. The play-putty is made with a simple mix of flour, water, salt, cream of tartar and vegetable oil—but the potential is much more than one may expect.

Homemade electrodes made of putty capture heart data as well as some commercial devices

The putty, made with basic ingredients found around the house, can effectively capture ECG measurements.
