Harmful effect of epinephrine on postreperfusion syndrome in an elderly liver transplantation recipient with sigmoid ventricular septum: A case report.

ABSTRACT:

Introduction

As a common morphological change of aging heart, sigmoid ventricular septum is frequently found during routine preoperative evaluation, but often disregarded because of its little clinical importance. However, in this report, we describe a 70-year old patient with sigmoid ventricular septum who developed severe hemodynamic deterioration during liver transplantation because of its unique morphology of heart.

Methods

During the course of reperfusion of the graft, patient's hemodynamics were closely monitored using transesophageal echocardiography.

Results

Immediately after graft reperfusion, epinephrine was given as a treatment of choice for postreperfusion syndrome. Surprisingly, however, hemodynamic derangement persisted and became even worse. Intraoperative transesophageal echocardiography revealed left ventricular outflow tract obstruction resulting from systolic anterior motion of the mitral valve leaflet. Therefore, the patient was treated with phenylephrine and fluid bolus under the guidance of transesophageal echocardiography.

Conclusion

As more elderly recipient present for liver transplantation surgery nowadays, left ventricular outflow tract obstruction should always be considered as a possible cause for hemodynamic instability during reperfusion period. In addition, transesophageal echocardiography is a useful tool for both diagnosis of hemodynamic derangement and guidance for appropriate management during liver transplantation surgery.
