Catastrophic Acute Thrombotic Occlusion During Fractional Flow Reserve Measurement


Figure 1.
Figure 1. A left coronary angiogram showed intermediate lesions in the left anterior descending and circumflex arteries.
Figure 2.
Figure 2. Measurement of the fractional flow reserve in the distal left anterior descending artery demonstrated a value of 0.91 (A). After measurement, we pulled back the pressure wire to the left main trunk, and the pressure curve (red line) obtained through the diagnostic catheter was damped (B).
Figure 3.
Figure 3. The left coronary angiogram obtained during the patient’s sudden collapse revealed total occlusion in the proximal circumflex artery.
Figure 4.
Figure 4. The intravenous ultrasound findings demonstrated thrombotic occlusion without dissection or plaque rupture.
Figure 5.
Figure 5. A large thrombus was successfully aspirated from the occluded circumflex artery using a thrombectomy catheter.
