COVID-19 and blood group in aortic valve replacement

The COVID-19 pandemic has been found to cause disproportionate harm in patients with cardiovascular disease, especially among the elderly population, among other risk factors. However, a new study published on the preprint server medRxiv* in June 2020 is the first to report its clinical features in patients with aortic stenosis who have had a transcatheter aortic valve replacement (TAVR).

Globaldata: Cardiovascular procedures not impacted by COVID-19 as heavily as other therapy areas

The COVID-19 crisis is not impacting cardiovascular procedures as heavily as it is other therapy areas, since the majority of these procedures are essential, according to GlobalData, a leading data and analytics company. GlobalData estimates that 96.7% of cardiovascular procedures performed in the US are essential procedures.
