- W4380687005 abstract "Introduction: Cardiac tamponade is a life-threatening condition requiring emergent intervention. Pericardial decompression syndrome (PDS) is a rare complication that presents as acute ventricular dysfunction following pericardiocentesis with a mortality rate up to 29%. In this case, we present a patient with PDS who developed cardiogenic shock following pericardiocentesis for cardiac tamponade. Clinical course: A 58-year-old female with no significant cardiac history presented with chest pain and dyspnea. Computed topography revealed a mediastinal mass and large pericardial effusion. Transthoracic echocardiogram (TTE) demonstrated the effusion with tamponade physiology. Left ventricular (LV) systolic function was preserved at this time. A total of 450ml of serosanguinous fluid was removed by pericardiocentesis, with minimal residual volume around the RV and a large effusion remaining around the LV. Repeat TTE 14 hours later revealed severe global hypokinesis and biventricular failure with an LV EF of 15%. The patient was started on inotropic therapy and transferred to our tertiary care center. Continuous diuresis and vasopressor therapy were initiated. Once stable, the patient was taken for pericardial window with further removal of 600ml of fluid. Subsequent TTE demonstrated recovery of LV systolic function to 47%. Discussion: Our patient developed cardiogenic shock secondary to biventricular heart failure following pericardiocentesis. This presentation is concerning for pericardial decompression syndrome. While the exact mechanism of PDS is not known, the current hypothesis postulates that drainage of fluid compressing the RV leads to a sudden increase in venous return. This abrupt change causes septal bowing and decreased LV systolic function. Some sources recommend draining pericardial fluid in smaller quantities; however, PDS may still occur at smaller volumes as was seen in our patient. PDS is a rare but life-threatening complication that requires vigilance post-pericardiocentesis regardless of volume removed." @default.
