Detection of Luminal-Intimal Border and Coronary Wall Enhancement in Intravascular Ultrasound Imaging After Injection of Microbubbles and Simultaneous Sonication With Transthoracic Echocardiography
.

.
We performed continuous intracoronary ultrasound recordings (EndoSonics; 20 MHz) in the proximal left anterior descending coronary artery before (Figure 1, A), during (Figure 1, B) and after injection (Figure 1, C) of 4 mL of SonoVue (ultrasound contrast agent with lyophilized capsule filled with sulfurhexafluoride). Simultaneously with contrast injection, ultrasound acoustic power of 0.6 mechanical index was delivered via a transthoracic transducer (2.5 MHz) toward the left main to sonicate the delivered microbubbles. Immediately after the passage of the microbubble contrast agent, which was clearly detected by the intracoronary ultrasound probe, an enhancement of the entire plaque and adventitia was seen. The luminal-intimal boundary appeared to show a ring-like enhancement, which clearly defined the inner borders of the coronary arterial wall.
