BACKGROUNDS: Intravascular ultrasound has been suggested to optimize stent diameter and length in Left Main (LM) procedures, but in the real-world ostial LM stenting is often accomplished with angiography only guidance. The Finet law which regulates the fractal geometry of human bifurcation has the potential to increase the accuracy of stent-sizing. To retrospectively evaluating the impact on outcomes of the addition of Finet Law to standard quantitative coronary angiography (QCA) in guiding stent selection of ostial LM stenting compared to standard angiography estimation...

High von Willebrand factor (VWF) levels have been reported to be associated with an increased risk of cardiovascular events. However, the relationship between VWF levels and coronary atherosclerosis in patients with coronary artery disease (CAD) who have already received stain treatment is still unclear. We examined the association between VWF levels and coronary plaque as assessed by intravascular ultrasound (IVUS) in CAD patients treated with statins. Ninety-one CAD patients who underwent percutaneous coronary intervention under IVUS guidance, and who were already receiving statin treatment based on Japanese guidelines, were included...

PURPOSE: To describe a single skin puncture technique combining subcutaneous injection of anesthetic to the depth of the vessel wall with venipuncture in the same movement. TECHNIQUE: Using ultrasound guidance, controlled anesthetic instillation along the needle tract and outer vessel wall with a 21-G vascular access needle can be combined with vessel puncture. This technique reduces the number of skin punctures and ensures accurate anesthetic instillation. The maximum inadvertent intravascular dose of commercial local anesthetic preparations that can be delivered with a small syringe is far below toxicity thresholds...

The ability of drug-eluting stent (DES) to inhibit intimal proliferation has resulted in a massive increase in their usage over the years. However, it is known that the application of DES can alter the normal cascade of vascular healing, resulting in delayed endothelialisation with risk of vascular complications. Coronary artery aneurysms (CAN) are defined as more than 50% dilatation of the coronary artery compared to the reference vessel diameter with the reported incidence after percutaneous intervention (PCI) being only around 0...

We report a case of percutaneous coronary intervention for spontaneous multi-vessel coronary dissection including the left main coronary artery. This case suggests that intracoronary imaging is useful for understanding the complex anatomy and for choosing the appropriate management for effective revascularization. Furthermore, cutting balloon angioplasty prior to stenting is useful for preventing the longitudinal extension of the intramural hematoma and avoiding unnecessary stent implantation.

Chronic pain is a common medical condition. Patients who suffer uncontrolled chronic pain may require interventions including spinal injections and various nerve blocks. Interventional procedures have evolved and improved over time since epidural injection was first introduced for low back pain and sciatica in 1901. One of the major contributors in the improvement of these interventions is the advancement of imaging guidance technologies. The utilization of image guidance has dramatically improved the accuracy and safety of these interventions...

PURPOSE OF REVIEW: Atherosclerosis has major morbidity and mortality implications globally. While it has often been considered an irreversible degenerative process, recent evidence provides compelling proof that atherosclerosis can be reversed. Plaque regression is however difficult to appraise and quantify, with competing diagnostic methods available. Given the potential of evidence synthesis to provide clinical guidance, we aimed to review recent meta-analyses on diagnostic methods for atherosclerotic plaque regression...

For several decades, most physicians have believed that acute coronary syndrome (ACS) is caused by coronary thrombosis resulting from rupture of vulnerable plaque characterized by a thin fibrous cap overlying a large necrotic core and massive inflammatory cell infiltration. However, nearly one-third of ACS cases are caused by plaque erosion characterized by intact fibrous cap, less or absent necrotic core, less inflammation, and large lumen. Because of the limitations of current imaging modalities, including angiography and intravascular ultrasound, the importance of plaque erosion as a cause of acute coronary events is less well known...

A 46-year-old man underwent coronary angiography for stable angina. He developed inferior ST-segment myocardial infarction during the angiography. Intravascular ultrasound (IVUS) findings suggested coronary vasospasm. Intracoronary administration of isosorbide dinitrate restored the coronary flow. This case illustrates the essential role IVUS imaging played in establishing the diagnosis of catheter-induced coronary vasospasm.

Procedural guidance with intravascular ultrasound (IVUS) imaging improves the clinical outcomes of patients undergoing percutaneous coronary intervention (PCI) by: 1) informing the necessity for lesion preparation; 2) directing appropriate stent sizing to maximize the final stent area and minimize geographic miss; 3) selecting the optimal stent length to cover residual disease adjacent to the lesion, thus minimizing geographic miss; 4) guiding optimal stent expansion; 5) identifying acute complications (edge dissection, stent malapposition, tissue protrusion); and 6) clarifying the mechanism of late stent failure (stent thrombosis, neointimal hyperplasia, stent underexpansion or fracture, or neoatherosclerosis)...

Although the hybrid chronic total occlusion (CTO) algorithm had many excellent recommendations, there has been infrequent adoption in the Asia Pacific region. The Asia Pacific CTO club propose an algorithm for case selection based on the Japan-CTO score and a new CTO algorithm, which is applicable globally. This algorithm allows for differing skill sets and equipment availability and contains practical teaching for CTO percutaneous coronary intervention. Similar to the hybrid algorithm there are 3 main questions that determine whether the primary approach is antegrade or retrograde: 1) is there proximal cap ambiguity; 2) is the distal vessel of poor quality; and 3) are there interventional collaterals present...
