OBJECTIVE: Embolized valves during transcatheter aortic valve replacement can cause myocardial ischemia by obstructing diastolic retrograde blood flow. KEY STEPS: To prove the described mechanism of ischemia, we performed aortography with catheter above the embolized valve and placed a stiff wire through the embolized valve, causing leaflet opening while monitoring electrocardiogram. As a treatment method, an aortic stent was implanted from the embolized valve into the aortic arch, enabling backflow and resolving the ischemia. POTENTIAL PITFALLS: Overlooking the described cause of ischemia is the biggest pitfall because it can be diagnosed and treated using simple techniques. TAKE-HOME MESSAGES: Embolized transcatheter aortic valve replacement valve can cause myocardial ischemia by blocking the diastolic backflow of blood. Aortography and opening of the embolized valve leaflets with wire can be used for diagnosis, and aortic stent implantation in the embolized valve can be used as a treatment modality.
