Trends in invasive treatment of patients hospitalized with aortic stenosis complicated by cardiogenic shock.

Since the introduction of TAVR, there has been a shift toward increased use of nonsurgical invasive treatments (both BAV and TAVR) for aortic stenosis and cardiogenic shock. Although in-hospital mortality has declined, it remains high in all groups, but particularly among patients treated with BAV, where the severity of cardiogenic shock appears to be higher than in those treated with other modalities.
