148 Pericardial Decompression Syndrome - a Case Report of Transient Ventricular Failure Post-pericardiocentesis
Heart Lung and Circulation(2020)
Abstract
Pericardial decompression syndrome (PDS) is a rare syndrome characterised by cardiac dysfunction following pericardiocentesis for large pericardial effusions with suspected tamponade [[1]Vandyke Jr., W.H.

It is a significant cause of morbidity in patients with metastatic malignancies [[2]Pradhan R. Okabe T. Yoshida K. Angouras D.C. DeCaro M.V. Marhefka G.D.

A 36-year-old male with metastatic lung adenocarcinoma presented with dyspnoea, tachycardia, hypotension, and right heart failure. Electrocardiogram showed electrical alternans and chest x-ray revealed cardiac enlargement. A transthoracic echocardiogram (TTE) demonstrated a large global pericardial effusion with features of tamponade. Pericardiocentesis immediately removed 1.2L of haemoserous fluid. Eleven hours later, the patient developed pulmonary oedema requiring diuretics and non-invasive ventilation. TTE revealed biventricular dilatation with severe global systolic dysfunction, and raised pulmonary pressures. A small residual pericardial effusion remained. CT coronary angiogram revealed calcium score of zero. He was discharged on bisoprolol, ramipril, and ivabradine. Progress TTE 6 weeks post-pericardiocentesis revealed resolution of systolic function. Three possible mechanisms include pre/afterload mismatch [[1]Vandyke Jr., W.H. Cure J. Chakko C.S. Gheorghiade M.

Intercostal catheters are routinely clamped to prevent re-expansion pulmonary oedema, however no such guidelines exist for pericardiocentesis. Here we suggest limiting immediate drainage to 200ml in order to reduce the likelihood of PDS. Further research on limiting the rate and volume of drainage may clarify how to prevent PDS.
