A pericardial window is a surgical procedure designed to relieve pressure caused by fluid accumulation around the heart, known as pericardial effusion. This fluid can lead to cardiac tamponade, a life-threatening condition where the heart’s ability to fill and maintain a cardiac output is jeopardized.
Compared to a pericardiocentesis, where a needle is used to access the pericardial space with a short-term catheter left in place, a pericardial window is a more permanent solution for draining pericardial fluid into the mediastinum, particularly when recurrent effusions are anticipated or when pericardiocentesis is not successful or feasible. The procedure can be performed thoracoscopically or with a small incision in the subxiphoid region, dissection up to the pericardium, and a small incision into the pericardium with subsequent effusion drainage.
In my practices as a cardiac anesthesiologist and intensivist, pericardial windows are critical for patients with recurrent effusions, especially in those with malignancies or following cardiac surgery. The choice of technique often depends on the patient’s overall condition and the underlying etiology of the effusion. Postoperatively, close hemodynamic monitoring is essential to relieve the tamponade physiology and detect any complications early.
This video shows a transesophageal echocardiogram (transgastric, mid-papillary view) initially with a very large effusion. As the video progresses, this effusion is drained leading to improved left ventricular filling.
