  • LVEDP and mean gradient measured by catheter during procedure. Major vascular complications include false aneurysm, dissection or complication requiring surgery or percutaneous intervention (simple haematoma not included in major vascular complications unless meeting criteria for major bleeding, that is, BARC ≥3).

  • AVR, aortic valve replacement; BARC, Bleeding Academic Research Consortium; BAV, balloon aortic valvuloplasty; LVEDP, left ventricular end-diastolic pressure; TAVI, transcatheter aortic valve implantation.
