Imaging findings
Cine fluoroscopy demonstrates a mechanical mitral valve prosthesis where one leaflet moves normally while the second leaflet is completely immobile and stuck in the closed position, explaining the patient's acute presentation with fulminant pulmonary edema.
Key takeaways
Mechanical valve dysfunction is a life-threatening emergency that can present as acute, severe heart failure and pulmonary edema. Cine fluoroscopy is a fast, highly effective, and non-invasive imaging modality to directly assess the mechanical excursion of prosthetic valve leaflets, allowing rapid confirmation of leaflet restriction or immobility.
