Emergency transcatheter aortic valve implantation for acute heart failure due to severe aortic stenosis in critically ill patients with or without cardiogenic shock.

Aims: Severe aortic stenosis can cause acute heart failure and cardiogenic shock (CS). Transcatheter aortic valve implantation (TAVI) is the standard therapy for aortic stenosis in inoperable patients. However, its role in this setting is poorly evaluated.
