Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

Pre-procedure CT imaging benefits LAA occlusion in Henry Ford study

There is not agreement among the top structural heart experts if CT is required for left atrial appendage occlusion (LAAO), but a Henry Ford Hospital study shows it can improve outcomes.

Regulatory Roundup: FDA clears AI-powered Apple Watch competitor, grants breakthrough designation to new heart failure device

Ancora Heart received the FDA’s breakthrough device designation for its AccuCinch Ventricular Restoration System, a new minimally invasive transcatheter device designed for the treatment of heart failure.

TAVR outcomes take a hit when patients present with heart failure or hypertrophic cardiomyopathy

In-hospital mortality was especially high among TAVR patients presenting with hypertrophic cardiomyopathy, according to a new analysis.

The KardiaBand device from AliveCor is a more reliable tool for identifying atrial fibrillation (AFib) than the Apple Watch 4, according to a new head-to-head analysis published in JACC: Clinical Electrophysiology.

KardiaBand outperforms Apple Watch in diagnosing AFib, but a cardiologist’s perspective is still crucial

The study's authors noted that the ECG acquisition technology in these wearable devices appears to be quite effective. The automated algorithms, however, could still be improved.

The projected number of acquired cardiomyopathy cases are expected to greatly outpace the number of new familial cardiomyopathy cases by 2031 in the U.S., driven mainly by poor lifestyles. This is expected to have a big impact on healthcare.

U.S. expected to see large rise in cardiomyopathy cases over next decade

“Even if we compensate for the differences in population size, the U.S. is still miles ahead when it comes to total cardiomyopathy cases," explained Walter Gabriel, MPH, an epidemiologist and analyst on the report.

New LAA occluder technology and the debate on echo vs. CT image guidance

At TVT 2022, there was debate whether CT imaging is needed for preplanning LAA procedures, and several new devices in development were discussed.

AFib patients more likely to be hospitalized for heart failure or bleeding following TAVR

The study, published in the American Journal of Cardiology, included data from more than 900 TAVR patients. Overall morality was 22.7% among patients with AFib and 14.4% among patients without AFib.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
