The Other Side of Tamponade: RP Impella Support in Pericardial Decompression Syndrome.

ABSTRACT:

Background

Pericardial decompression syndrome (PDS) is a rare complication of pericardiocentesis, characterized by acute right ventricular (RV) failure and circulatory collapse.

Case summary

A 32-year-old man with a mediastinal mass and malignant pericardial effusion developed severe RV dysfunction and shock shortly after pericardiocentesis. Despite escalating therapy, emergent placement of an Impella RP heart pump stabilized hemodynamics and resulted in full RV recovery within 72 hours. The patient was subsequently diagnosed with primary mediastinal large B-cell lymphoma and discharged to continue chemotherapy.

Discussion

PDS carries significant mortality risk. Early diagnosis using echocardiographic and invasive hemodynamic markers is critical. This case demonstrate
