Figures

Figure 1
Figure 1
Contrast-enhanced CT scan at the level of the right main pulmonary artery (PA) demonstrating a linear intraluminal hypodensity. Ao, Aorta.
Figure 2
Figure 2
TEE, three-dimensional, left atrial view of the mitral valve in late systole. The leaflet segments are demonstrated. Flail involving the A3 segment is clearly seen.
Figure 3
Figure 3
TEE, midesophageal long-axis view with color compare. In the left-hand frame, a flail segment of the anterior mitral leaflet is seen (arrow). In the right-hand frame, an eccentric, posterior jet of severe mitral regurgitation is evident. LA, Left atrium; LVOT, left ventricular outflow tract.
Figure 4
Figure 4
TEE, transgastric two-chamber view. The posteromedial (PM) and anterolateral (AL) papillary muscles are demonstrated. Partial rupture of the PM papillary muscle is shown (arrow). In the associated clip, the ruptured head of the papillary muscle can be seen flicking freely in the LV.
Figure 5
Figure 5
TEE, modified midesophageal four-chamber view in late systole demonstrating severe tricuspid regurgitation. CS, Coronary sinus; RA, right atrium.
Figure 6
Figure 6
TEE, midesophageal four-chamber view in late systole. A flail segment of the anterior mitral leaflet is seen (arrow). However, there is no obvious abnormality of the tricuspid valve, despite the presence of severe tricuspid regurgitation (see Figure 5). LA, Left atrium; RA, right atrium.
Figure 7
Figure 7
TEE, three-dimensional multiplanar reconstruction of the tricuspid valve in late systole. Prolapse involving the septal leaflet of the tricuspid valve is evident (arrow), which was not apparent on standard two-dimensional imaging (see Figure 6).
Figure 8
Figure 8
TEE, modified midesophageal right ventricular inflow outflow view. A mobile, linear shadow is seen in the RVOT (arrow). In addition, the free wall of the RVOT appears thickened, consistent with myocardial contusion. LA, Left atrium; LVOT, left ventricular outflow tract.
