Emergency transcatheter aortic valve implantation in patients with severe aortic regurgitation and a left ventricle assist device: A case report and systematic review.

BACKGROUND

Cardiogenic shock due to severe aortic regurgitation in patients with left ventricle assist devices is a life threatening condition. Here, we consider transcatheter aortic valve implantation as a treatment option.

METHODS AND

RESULTS

A patient with a left ventricle assist device was presented to us with cardiogenic shock due to severe aortic regurgitation. We successfully implanted a transcatheter aortic valve in emergency setting. The patient recovered and underwent cardiac transplantation three months afterwards. We performed a systematic literature review and identified 10 cases of patients with a left ventricle assist device undergoing transcatheter aortic valve implantation. In these cases, there was no procedural related mortality reported. In four (40%) patients, transcatheter aortic valve implantation resulted in significant paravalvular aortic regurgitation. In two of these cases it was due to migration of the valve towards the left ventricle.

CONCLUSIONS

Our case report and review of literature suggests that transcatheter aortic valve implantation is a feasible and lifesaving treatment option for left ventricle assist device patients presenting with severe aortic regurgitation.
