Guide wire fracture during percutaneous coronary intervention (PCI) is rare. It can cause fatal complications such as thrombus formation, embolization, and perforation. Guide wire fracture could occur during intervention for severely calcified stenotic lesions, and rarely from distal small branches of stenotic lesions. There are several methods for its management depending on the material character, position, length of the remnant, and the patient's condition. If percutaneous retrieval was not achieved, the surgical procedure should be considered for prevention of potential risks, although the remnant guide wire does not usually cause complications. We experienced a patient with a guide wire fracture during PCI, and managed to prevent its complications through surgical removal of the remnant wire. We report this case here.

During percutaneous coronary intervention, guidewire fractures are very exceptionally encountered in medical practice, but can cause fatal complications such as intracoronary thrombus formation, embolization and perforation. Removal of the remnant segments of guidewire is important for the prognosis. There are several methods being recommended for the treatment of fractured guidewire remnants. However, the best treatment of remnant guidewire filament is still unclear. Herein, we present a case where we did not completely remove remnant guidewire filaments that caused fatal coronary thrombosis.

There have been a growing numbers of patients diagnosed with malignancy and coronary artery disease simultaneously or serially. In the era of percutaneous coronary intervention (PCI), stent thrombosis has been a rare but challenging problem. Recently, we experienced two unique cases of acute stent thrombosis in patients with malignancy. The first case showed acute and subacute stent thrombosis after PCI. The second case revealed simultaneous thromboses in stent and non-treated native coronary artery. We believe that we need rigorous precautions in the treatment of patients with coronary artery disease and malignancy, especially with regards to deciding how and whether to revascularize, as well as which anti-platelet agents to select.

A coronary pseudostenosis is a characteristic angiographic image, which may appear as coronary winkles, or intussusceptions, due to a stiff guidewire during coronary interventions. Intravascular ultrasound (IVUS) plays a role in ruling out severe coronary stenosis, coronary dissections, thrombus or coronary spasm. We report a case of coronary pseudostenosis, which occurred during coronary interventions, diagnosed by intravascular ultrasound.

Animal models of coronary microcirculation dysfunction are useful in research on the pathology of coronary microcirculation dysfunction and its intervention mechanisms. Currently, such animal modes are prepared mainly by mechanical obstruction and chemical damage form coronary microembolization or microthrombosis. This paper summarizes the currently available preparation techniques and compared their advantages and disadvantages.

8.Understanding the Coronary Bifurcation Stenting
Korean Circulation Journal 2018;48(6):481-491
Coronary bifurcation stenting is still complex and associated with a high risk of stent thrombosis and restenosis even with contemporary techniques. Although provisional approach has been proved to be the standard strategy of treatment, There is still lack of evidences for multiple steps of the procedure. For so many years we have been focused on the optimization of side branch (SB), but the clinical outcome is mostly dependent on the main vessel (MV) stenting. The optimal expansion of MV stent without the compromise of SB is the ultimate goal to achieve in the coronary bifurcation stenting. Understanding the anatomy and physiology of coronary bifurcation lesion should be the most important step to this goal. The relationship of vessel diameter between branches and the anatomical and functional significance of plaque shift and carina shift are two most important concepts to understand. They are the science behind the predictors of SB occlusion, and the rationale of proximal optimization technique and final kissing ballooning. This specific review will be devoted to review those concepts as well as clinical evidences to support them.

Percutaneous coronary intervention (PCI) of stumpless chronic total occlusion (CTO) lesions with a side branch stemming from the occlusion have a significantly lower treatment success rate because physicians cannot identify an accurate entry point with only conventional angiographic images. An intravascular ultrasonography (IVUS)-guided wiring technique might be useful for the penetration of stumpless CTO. We recently experienced thrombotic occlusion during an IVUS-guided stumpless CTO procedure. The cause of the thrombosis is not completely understood; the thrombosis may have been associated with the long use of the IVUS catheter. Special precautions should be taken to prevent thrombus in such cases.

Simultaneous thrombosis of multiple coronary arteries in acute myocardial infarction is very rare in clinical settings. Its mechanism is not yet clear, but patients displaying multivessel simultaneous thrombosis tend to have poor clinical outcomes. Hence, it is important to recognize this condition and provide timely and proper management. We report a case of simultaneous thrombosis involving multiple coronary arteries in a patient with ST-segment elevation myocardial infarction.
