Aortic prosthesis misplacement
Embolization towards the aorta or left ventricle
Deployed valve is positioned too high (towards the aorta) or too low (towards the mitral valve apparatus)
Aortic regurgitation
Central
Paravalvular (Figure 11)
Mitral regurgitation
Aortic prosthesis impinges on the anterior mitral leaflet (Figure 10)
Left ventricle asynchrony caused by right ventricular pacing
Damage or distortion of the subvalvular mitral apparatus by delivery system
New left ventricular wall motion abnormalities
Acute coronary ostial occlusion
Cardiac tamponade
Perforation of the left or right ventricle
Dissection or rupture of the aortic root
