Acute Saddle Embolus With Thrombus in Transit: A Case Report and Review of the Literature.

Pulmonary embolism is a life-threatening medical emergency associated with right ventricular failure. Rarely, it impacts the left ventricle to the point of compromising the left ventricular (LV) ejection fraction. We present a case of a 73-year-old African American male with a medical history pertinent for intravascular large B-cell lymphoma who developed an acute saddle embolus with a "clot-in-transit" and profound LV systolic dysfunction.
