Follow-up echocardiography. Echocardiography 1 week after surgery showed normal all chambers, normal left ventricles (LV) systolic function with normal kinetic at rest, normal diastolic function, mild mitral regurgitation (MR), low probability of pulmonary hypertension (PH), mild tricuspid regurgitation (TR), reduced right ventricle (RV) contractility, blood clot at pericardial cavity (2.9 x 1.9 cm2) detected at the right atrium's free wall (a). The pericardial hematoma (arrows) was enlarged (2.5 x 3.0 cm2) (b), and echocardiography 3 months after surgery large pericardial hematoma (3.4 x 4.4 cm2) with dilated SVC orifice (c).

ASD patch was visualized with no residual ASD shunt. An echo-lucent mass (2.9 x 1.9 cm2), suggestive hematoma, was visualized at the pericardial space near the right atrium (RA) (Figure 1(a)). An echocardiogram revealed the hematoma was expanding and slightly compressing the RA (Figure 1(b) and (c)), with no intracardiac hemodynamic abnormalities.
CT scan shows distinct hematoma (arrows) without any sign of compression of cardiac structures (a). Three months after surgery, expanding pericardial hematoma compressing the SVC, extending anterosuperiorly to the level of the aortic arch (b). Collateral vessels were also visualized (c).. Note: Asterisk showing vein compression.

CT scan showed distinct hematoma without any sign of compression of cardiac structures (Figure 2(a)). Considering that the patient was asymptomatic and hemodynamically stable, she was discharged from the hospital and planned for monthly follow-up. The hematoma extended anterosuperiorly to the level of the aortic arch (Figure 2(b) and (c)).
