Left Ventricular Outflow Tract Occluding Thrombus After Biventricular Mechanical Circulatory Support as a Bridge to Recovery

Abstract

The role of mechanical circulatory support for cardiopulmonary failure is expanding. Anticoagulation in the setting of static blood, hypercoagulable states, extracorporeal circuits, and surgery presents an intricate and delicate balance. We present a patient with large, biventricular thrombi during and succeeding biventricular mechanical support. Management of the thrombi and device selection in this patient are discussed.

Left ventricular outflow tract thrombus in a child with dilated cardiomyopathy: An atypical location

“…Few authors have described the occurrence of a thrombus in the LVOT. [89] Most of these cases were associated with LVOT obstruction and syncope. This did not occur in this case possibly because of its size and location.…”

Left ventricular outflow tract thrombus detected by echocardiography in a young man with a structurally normal heart: Case report and literature review

“…One reported case of LVOT thrombus was attributed to transient eosinophilia [16] . In the other case, thrombus formation in the LVOT was discovered during surgery in a patient on biventricular mechanical support [17] . Here we report a case of LVOT thrombus in a young man with a structurally normal heart incidentally detected by echocardiography after a motor vehicle accident.…”
