Pericardial decompression syndrome (PDS) is defined as paradoxical hemodynamic deterioration associated with left, right, or bi-ventricular dilation and systolic dysfunction following pericardiocentesis. It is uncommon yet under-recognized, underreported, and associated with significant morbidity and mortality. ⋯ PDS, although rare, can lead to significant morbidity and mortality. Left ventricular apical thrombosis could result from PDS in the setting of hypercoagulable state. Treatment of the underlying disease may lead to successful resolution of PDS and its complications.
