Pericardial Window

This information is for patients who did not have open heart surgery.

What is the pericardium?
The pericardium is a sac that surrounds the
heart. It holds just enough fluid to pad and
lubricate the heart muscle. Disease,
infection, or injury can cause fluid to build
up in this sac. The pressure from this extra
fluid can make it hard for the heart to pump
as it should.

What is a pericardial effusion?
A pericardial effusion is an abnormal
amount of fluid between the heart and the
heart sac. This abnormal fluid may be
caused by, a viral infection, cancer, renal
disease, heart failure, hypothyroidism, and
after cardiac surgery. A pericardial window
is used to make a diagnosis and to make the
heart work better.

What is a pericardial window?
A pericardial window can be made with a
small cut below the end of the breastbone
(sternum) or with a small cut between the
ribs on the left side of the chest. A cut is
made in the heart sac to drain fluid that has
built up around the heart. A tube may be
placed to drain extra fluid for a short time
after surgery. This helps the heart pump
better again.

What are the reasons for a pericardial
 Fluid build-up around the heart.
 Allows us to see areas that may need
to be tested or biopsied. Biopsies, or
tissue samples, may be needed when
some lung tumors occur. Lung
tumors may be benign (non-
threatening) or malignant

What should I expect?
An intravenous line (IV) will be placed in
your arm to give you medicines during the
