*Logistic regression adjusting for age, logistic Euroscore, atrial fibrillation, coronary artery disease and a PCI in the 30 days preceding the emergency procedure. Following adjustment also for aortic regurgitation, mitral regurgitation and reanimation, respectively, does not notably alter the results (data not shown).

eBAV, emergency balloon valvuloplasty; eTAVI, emergency transcatheter aortic valve implantation; TAVI, transcatheter aortic valve implantation.
