Introduction:
We describe a patient who developed severe aortic regurgitation following Impella left ventricular assist device implantation requiring aortic valve replacement.
Case Report:
A previously healthy 34-year-old female presented with chest pain and flu-like symptoms. Electrocardiogram showed widespread ST elevation and serum troponin was raised, consistent with myocarditis. Coronary angiography was normal but the right coronary artery dissected. Subsequent cardiogenic shock required veno-arterial extracorporeal membrane oxygenation and Impella implantation. Myocardial function recovered, but upon removal of the Impella, severe aortic regurgitation was present and she underwent aortic valve replacement, making a full recovery.
Discussion:
Aortic regurgitation is a rare complication of Impella implantation, and to our knowledge, this is the first reported case successfully treated with aortic valve replacement. Veno-arterial extracorporeal membrane oxygenation and Impella used in tandem are relatively novel, and may add synergistic benefit to strategies for acute cardiogenic shock.
Conclusion:
Echocardiography must include frequent assessment of both valvular and myocardial function after Impella removal.
