Goals of Imaging during TAVI During the procedure procedure guidance detection of complications After the procedure Result assessment
Detection of Complications Severe AR Tamponade … LV obstruction Coronary occlusion
TAVI and AR Confirm the severity Locate the AR: central or paravalvular Check the function and deployment of the prosthesis
Mild AR
Massive AR
TAVI and AR Confirm the severity Locate the AR: central or paravalvular Check the function and deployment of the prosthesis
Small Periprosthetic Leak
Massive Central AR
TAVI and AR Confirm the severity Locate the AR: central or paravalvular Check the function and deployment of the prosthesis
AR along the Guidewire
Structural Dysfunction
Native Valve Prolapse Impending Prosthesis
Prosthesis too Low
Underexpansion of the Valve
TEE after over expansion of an MCV
Could we perform TAVI without TEE/general anesthesia?

Conclusions In the early experience general anesthesia and TEE guidance are recommended Then the Heart Team could move towards simplification of the procedure: loco regional anesthesia, abandoning of radial artery /urinary catheters in « simple cases » then as a default approach Loco regional anesthesia does not mean absence of an anesthetist TEE should be available in both transapical and transaortic approach and in cases of complication especially severe AR
