Medicine: Managing aortic stenosis, Warning about a gout drug

The first medical topic today:
Three clinical studies published in 2019 led to the conclusion either open-heart surgery or minimally invasive heart surgery will be used more often in the future in patients with aortic stenosis. The minimally invasive heart surgery for aortic stenosis is transcatheter aortic valve replacement. The three clinical studies published in 2019 showed that either open-heart surgery or minimally invasive heart surgery (that is, as mentioned, transcatheter aortic valve replacement for the patients with aortic stenosis), can now expand also to lower-risk patients.
The second medical news today:
A warning has been issued about a gout drug. The U.S. Food & Drug Administration (the FDA) has mandated that the drug febuxostat for patients with gout carries a boxed warning, I repeat, a boxed warning, in other words, a highly visible warning, to alert doctors and patients to the increased risk of death due to cardiovascular causes as a side effect of febuxostat.
