The study, called IVUS-DCB, is the first randomized controlled trial to demonstrate the clinical benefits of using IVUS in angioplasty procedures for peripheral artery disease (PAD), a condition in which plaque builds up in arteries in the legs. The study was funded by Medtronic, Inc. and Korea United Pharm.

The study focused on patients who underwent PCI for acute coronary syndromes (ACS)—life-threatening conditions which include heart attacks and chest pain caused by decreased blood flow to the heart—with stents containing drugs to prevent further plaque buildup. Stents were supplied by Medtronic Corp. Minnesota, U.S.)

It provides detailed information about the vessel wall, plaque composition, and blood flow characteristics, enabling more accurate diagnosis and treatment planning. During the roundtable, participants highlighted the potential of IVUS in guiding revascularization procedures, such as angioplasty and stenting, to optimize outcomes for patients.

Although it is statistically unlikely, multiple plaque ruptures are possible. On intravascular ultrasound (IVUS), the mid RCA plaque was described as "cratered, inflamed, and bulky," and the OM plaque was described as "bulky with evidence of inflammation and probably ulceration."

Symptomatic stenosis (63.9% vs. 94.7%, p<0.05) was more common in the with-POWER group.

Given the presentation, the cardiologist stented the vessel and the patient returned to the ICU for ongoing critical care. On the other hand, if this was idiopathic VF and the interventionalist stented a stable moderate LAD lesion (remember, 60% is considered non-obstructive), the patient should have ICD implantation prior to discharge.

Smith comment : a very high proportion of MINOCA are ruptured plaque with lysed thrombus. That plaque is at risk of thrombosing again. It is worthwhile remembering that the majority of plaques which rupture are non-obstructive before they ulcerate and thrombose. Most plaque is outside the lumen!!

The scan did not find PE, but showed evidence of coronary plaque: There are areas of dense white in the LAD (red and blue circles) and in the first diagonal (green circle). All three lesions had TIMI 2 flow prior to stenting. This is an RAO cranial projection of the left coronary vessels after thrombectomy and stenting.

And finally, after placement of a stent in the LAD: Before and after: (Unfortunately, this resulted in the "jailing" of the septal branches behind the stent and probably some degree of plaque shift which is why they do not opacify well in the "after" shot. This was the cost of preventing infarction of the anterior wall.)

The operator performed intravascular ultrasound and visualized acute plaque rupture with thrombus formation and placed a stent. He is very lucky that he spontaneously reperfused and was stented before he had the chance to re-occlude. There was an 80% lesion in the mid to distal RCA with TIMI 3 flow (meaning normal flow).

The reason being, there is a huge healthy population ( with zero risk factor) , but showing insignificant or minimal coronary plaques. In adults, some of these streaks become prominent locally and turn out to be plaque. The argument for intensive statin therapy is to stabilize these plaques. 2024 May 4;403(10438):1753-1765.
