Embolism Ischemia Thrombosis

Many of the changes seen are reminiscent of LVH with “strain,” and downstream Echo may very well corroborate such a suspicion, but since the ECG isn’t the best tool for definitively establishing the presence of LVH, we must favor a subendocardial ischemia pattern, instead. Type I ischemia. Type II ischemia.

In this phenomenon, a thrombus forms within the lumen of the stent graft component of the frozen elephant trunk prosthesis and puts the patient at risk for downstream embolization with visceral or lower limb ischemia. Therefore, the presence of ILT is associated with increased short-term mortality and morbidity.

This suggests further severe ischemia. MINOCA may be due to: coronary spasm, coronary microvascular dysfunction, plaque disruption, spontaneous coronary thrombosis/emboli , and coronary dissection; myocardial disorders, including myocarditis, takotsubo cardiomyopathy, and other cardiomyopathies. And yet the arteries remain open.

In terms of ischemia, there is both a signal of subendocardial ischemia (STD max in V5-V6 with reciprocal STE in aVR) AND a signal of transmural infarction of the inferior wall with Q wave and STE in lead III with reciprocal STD in I and aVL. The rhythm is atrial fibrillation. The QRS complex is within normal limits.

MINOCA may be due to: coronary spasm, coronary microvascular dysfunction, plaque disruption, spontaneous coronary thrombosis/emboli , and coronary dissection. link] We know that most type 1 acute MI due to plaque rupture and thrombosis occurs in lesions that are less than 50% (see Libby reference).

CT angiogram chest: no aortic dissection or pulmonary embolism. This may occur as a result of blunt chest trauma or other acute stress that produces a sudden extreme shear force on a coronary artery ( that can result in an intimal tear that leads to intraluminal thrombosis ). No further troponins were measured. Was this coincidence? —

Third, a slow motion segment showing delayed, brisk filling of the PDA due to dislodgment of a thrombus from contrast injection and distal embolization. A distal RCA lesion ( blue arrow ), Delayed brisk filling of an initially occluded PDA due to a thrombus dislodged during injection which embolized distally.
