| 41. | The pericardial sac is particularly well suited for a valve leaflet due to its extremely durable physical properties.
|
| 42. | Pericardial effusion etiologies have changed over time and vary greatly depending on geography and the population in question.
|
| 43. | Extension of the lesions into the chest may lead to the development of chylous pleural and pericardial effusions.
|
| 44. | When pericardial effusion is suspected, echocardiography usually confirms the diagnosis and allows assessment for signs of hemodynamic instability.

|
| 49. | The benefactor dies, after being initially stabilized following a femoral artery catheterization, from causes attributed to pericardial tamponade.
|
| 50. | The pericardial valve is not simply another valve, it is the embodiment of a concept of tissue valve construction.
