Week in Review: Head-to-head TAVR research | How early marijuana use affects the heart | AI predicts CVD mortality

The global trial is designed to compare TAVR systems from Medtronic and Edwards Lifesciences when treating patients with small annuli.

The FDA and CDC announced the recommendation in a new joint statement. Nearly 7 million doses of the Johnson & Johnson vaccine have been administered in the United States so far. 

The Mediterranean diet typically prioritizes eating fruits and vegetables and limiting fatty foods and animal products.

Researchers used ultrasound imaging to examine the hearts of young adults who smoked marijuana and those who did not. Their full analysis was published in the Journal of Applied Physiology

Sharing their findings in Radiology: Cardiothoracic Imaging, the researchers said their AI model should be easy to implement without creating a lot of additional work. 

Medtronic first initiated the recall, which includes a total of 239,171 devices, in February.

Researchers explored data from more than 130,000 participants for this new meta-analysis, sharing their findings in the American Journal of Preventive Cardiology.

The team sees significant potential in its findings, though they still hope to make the technique "simpler and more clinically implementable."

The risk of post-TAVR pacemaker implantation also goes up when treating elderly patients. 

Improved diversity can benefit clinicians and patients alike, according to a new analysis in the Journal of the American College of Cardiology.
