Author ProfileAbstract
A 69-year-old woman with mechanical aortic valve presented with
decompensated heart failure. Emergent echocardiogram and fluoroscopy
demonstrated acute aortic regurgitation due to a dysfunctional
mechanical aortic valve and non-obstructive coronary disease. An
emergent valve replacement was performed confirming fixed-open valve
with pathology demonstrating obstructive pannus formation without
thrombosis or vegetation.
