Other TAVI-Related Complications

Conversion to open surgery
 Conversion to open sternotomy during the TAVI procedure secondary to any procedure-related complications
Unplanned use of cardiopulmonary bypass (CPB)
 Unplanned use of CPB for hemodynamic support at any time during the TAVI procedure
Coronary obstruction
 Angiographic or echocardiographic evidence of a new, partial or complete, obstruction of a coronary ostium, either by the valve prosthesis itself, the native leaflets, calcifications, or dissection, occurring during or after the TAVI procedure
Ventricular septal perforation
 Angiographic or echocardiographic evidence of a new septal perforation during or after the TAVI procedure
Mitral valve apparatus damage or dysfunction
 Angiographic or echocardiographic evidence of new damage (chordae papillary muscle, or to the leaflet) to the mitral valve apparatus or dysfunction (e.g. restrictions due to the THV) of the mitral valve during or after the TAVI procedure
Cardiac tamponade
 Evidence of a new pericardial effusion associated with hemodynamic instability and clearly related to the TAVI procedure
 Any one of the following:
  Fulfillment of the Duke endocarditis criteria
  Evidence of abscess, paravalvular leak, pus, or vegetation confirmed as secondary to infection by histological or bacteriological studies during a re-operation
  Findings of abscess, pus, or vegetation involving a repaired or replaced valve during an autopsy
Valve thrombosis
 Any thrombus attached to or near an implanted valve that occludes part of the blood flow path, interferes with valve function, or is sufficiently large to warrant treatment. Note that valve-associated thrombus identified at autopsy in a patient whose cause of death was not valve-related should not be reported as valve thrombosis
Valve malpositioning
 Valve migration
  After initial correct positioning, the valve prosthesis moves upwards or downwards, within the aortic annulus from its initial position, with or without consequences
 Valve embolization
  The valve prosthesis moves during or after deployment such that it loses contact with the aortic annulus
 Ectopic valve deployment
  Permanent deployment of the valve prosthesis in a location other than the aortic root
TAV-in-TAV deployment
 An additional valve prosthesis is implanted within a previously implanted prosthesis because of suboptimal device position and/or function, during or after the index procedure

TAVI = transcatheter aortic valve implantation; THV = transcatheter heart valve.
