Giant Left Ventricular Thrombus Rapidly Developing in an Extremely Short Period of Time in a Patient With Severe Systolic Dysfunction

Although left ventricular thrombi (LVTs) are closely related to the prognosis of patients with systolic dysfunction, anticoagulation therapy is not recommended for the primary prevention of LVTs in patients with sinus rhythm heart failure. We report a case of a patient with systolic dysfunction who developed a giant LVT in an extremely short period of time (one month) after an infection. The LVT led to acute limb ischemia, gangrene, and death. Additionally, we incidentally detected pulmonary thrombosis in this patient.
