👉 The Glenn fluid, also known as pericardial effusion, is an accumulation of fluid within the pericardial sac surrounding the heart. This fluid can result from various causes, including inflammation (such as pericarditis), infection, trauma, or malignancy. In its most common form, it is non-cardiogenic, meaning it does not originate from the heart itself but from elsewhere in the body. The fluid can be clear or blood-tinged, and its presence can lead to symptoms like chest pain, shortness of breath, or palpitations due to increased pressure on the heart. Diagnosis typically involves imaging studies like echocardiography, and treatment depends on the underlying cause, ranging from medications to surgical interventions.
