Graphical abstract
Figure 1
Figure 1
(A-D) Transthoracic echocardiogram (TTE), parasternal long-axis view without (A) and with color Doppler (B), showing severe mitral regurgitation. TTE apical four-chamber view (C-D) again showing severe mitral regurgitation.
Figure 2
Figure 2
Transesophageal echocardiogram midesophageal window, commissural view showing a 1.2 × 1.2 cm echodensity attached to the left atrial wall just above the left atrial appendage (LAA) but not within the appendage. Also notice the thickened mitral valve leaflets.
Figure 3
Figure 3
(A-C) Cardiac magnetic resonance images demonstrate left atrial mass along the left superolateral wall, adjacent to the atrial appendage base, measuring 1.3 × 1.2 cm, of intermediate T1 signal intensity (A), mildly hyperintense T2 signal intensity (B), and with avid enhancement on postcontrast fat-suppressed T1-weighted images obtained after the intravenous administration of 13 mL of gadolinium-based contrast (MultiHance; C).
Figure 4
Figure 4
Positron emission tomography/computed tomography tumor imaging with Gallium-68 Dotatate, 5.4 mCi showing abnormal tracer localization corresponds to the known left atrial mass. This finding is most compatible with somatostatin receptor-rich lesions, e.g., cardiac carcinoid.
Figure 5
Figure 5
Transesophageal echocardiogram (TEE) midesophageal window, two-chamber view showing left atrial mass with significant growth (5.1 × 2.2 cm) compared with the previous TEE 6 weeks ago. There is prolapse of the mass into the left ventricle during systole resulting in obstruction of the mitral valve.
