Title of Case: Etiology and treatment of pericardial tamponade.

Background: While in the SICU, I was involved in the care of a patient that presented with pericardial tamponade. He subsequently underwent a pericardiocentesis and a pericardial window. I was interested in the specific causes of pericardial effusions/tamponade as well as the incidence of each cause. Furthermore, I was interested in the treatment of cardiac tamponade. Specifically deciding between pericardiocentesis versus pericardial window.

Case presentation:

HPI: 45-year-old male with past medical history of hypercholesterolemia and hypertension who presented with chest pain. Patient had been moving furniture with his wife all morning. After some time he developed chest …show more content…

SVC appeared normal

Patient Management:
He immediately had a stat CTA performed and was found to have a pericardial effusion. A pericardiocentesis was then attempted yielding a minimal amount of bright red blood. Patient then proceeded to code in the ER and was revived. It was then decided to take the patient to the OR to perform pericardial window. The pericardial window yielded 300ml of blood. Following the pericardial window he remained in critical condition in SICU.
Following this presentation he underwent a workup for the possible etiology of the pericardial effusion including pericardial fluid pathological analysis and culture, pericardial tissue pathological analysis, thyroid function tests, HIV and TB tests, and a rheumatic …show more content…

Benefits of a pericardial window include the ability to take diagnostic biopsies as well as to perform pericardiectomy if needed. Surgical exploration is also useful for cases that involve fluid reaccumulation and loculated fluid. In terms of traumatic cases a pericardial window may be more preferred especially in cases of aortic dissection or myocardial rupture. One study looked at 100 patients presenting with cardiac tamponade at a single center. Of the patients, 38% received pericardiocentesis only, 26% received surgical treatment only and 26% received pericardiocentesis followed by surgical treatment. Complication rates and mortality rates were highest in the two surgical groups leading the authors to conclude that pericardiocentesis should be performed first in idiopathic cases and in patients with hemodynamic instability. However, they further concluded that surgery may be the best approach for trauma and those with recurrent effusions where mortality rates may be higher
