ST-Segment Elevation Myocardial Infarction Caused by Embolized Transcatheter Aortic Valve in Ascending Aorta.

ABSTRACT:

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
