Illustration
 
Four-chamber view
Figure 1: Apical four-chamber view: globally moderately reduced left ventricular function, enlarged left atrium, lateral hypo- to akinesia.


Keywords: apical four-chamber view, echocardiogram, cardiology, left ventricular function

Long axis
Figure 2: Apical long axis: globally moderately reduced left ventricular function, enlarged left atrium, posterolateral hypo- to akinesia.


Keywords: apical long axis, echocardiogram, cardiology, left ventricular function

Pulsed Doppler - Mitral Doppler
Figure 3: Pulsed Doppler - mitral valve: Restrictive flow profile with high E-wave, rapid deceleration of the E-wave, I / O-amplitude> 2 and signs of delayed myocardial relaxation (L-wave) following the E-wave.


Keywords: Doppler, echocardiogram, cardiology, mitral valve
 
 
Pulsed Doppler
Figure 4: Pulsed tissue Doppler of the lateral mitral annulus: very low early diastolic myocardial velocity (E 'wave). An amplitude ratio of E_mitralis / E´ of> 15 corresponds to an increased left ventricular filling pressure.


Keywords: Doppler, echocardiogram, cardiology, mitral annulus
 
 
CW Doppler
Figure 5: CW Doppler of the aortic valve prosthesis: high maximum speed, relatively high mean gradient despite reduced left ventricular pump function.


Keywords: aortic valve prosthesis, CW Doppler, echocardiogram, cardiology
 
 
Pulsed Doppler - LVOT
Figure 6: Pulsed Doppler of the left ventricular outflow tract (LVOT): low velocity, low velocity-time integral (VTI). The LVOT / VTI / aortic prosthesis VTI ratio of only 0.23 is low (normal for two-leaflet valve prostheses 0.41 ± 12), which results in a calculated prosthesis opening area of ​​0.73 cm2 with an LVOT diameter of 20 mm.


Keywords: Doppler, echocardiogram, cardiology, LVOT
 
 
Transesophageal echo-aortic valve
Figure 7: Transesophageal echo of the aortic valve prosthesis (longitudinal axis, 108 °): The valve play cannot be adequately assessed, but note the narrow ascending artery following the prosthesis (significantly smaller than 3 cm).


Keywords: aortic valve, echocardiogram, cardiology

Transesophageal echo-aortic valve
Figure 8: Transesophageal echo of the aortic valve prosthesis (cross section 51 °): The valve play is better, but still not optimally assessable.


Keywords: aortic valve, echocardiogram, cardiology

Fluoroscopy projection
Figure 9: Radiography RAO 10 °, side view of the prosthesis: clearly free valve play.


Keywords: cardiology, flaps, projection
 
 
Ascending aorta
Figure 10: Ascending diameter only 2.6 cm.


Keywords: ascending aorta, echocardiogram, cardiology
