Background and objectives Diffuse long coronary artery disease (DLCAD) still has unfavorable clinical outcomes after successful percutaneous coronary intervention (PCI). Therefore, we aimed to evaluate the effectiveness and safety of Resolute™ zotarolimus-eluting stent (R-ZES; Resolute™ Integrity) for patients with DLCAD. Methods From December 2011 to December 2014, 1,011 patients who underwent PCI using R-ZES for CAD with longer than 25 mm lesion were prospectively enrolled from 21 hospitals in Korea. We assessed the clinical outcome of major adverse cardiac events (MACE) defined as the composite of cardiac death, non-fatal myocardial infarction (MI), and clinically-driven target vessel revascularization at 12 months. Results Mean age was 63.8±10.8 years, 701 (69.3%) patients were male, 572 (87.0%) patients had hypertension, 339 (33.8%) patients had diabetes, 549 (54.3%) patients diagnosed with acute MI and 545 (53.9%) patients had multi-vessel disease (MVD). A total of 1,697 stents were implanted into a total of 1,472 lesions. The mean diameter was 3.07±0.38 mm and the length was 28.27±6.97 mm. Multiple overlapping stents were performed in 205 (13.8%) lesions. A 12-month clinical follow-up was available in 1,004 patients (99.3%). The incidences of MACE and definite stent thrombosis at 12-month were 3.0% and 0.3% respectively. On multivariate Cox-regression analysis, multiple overlapping stents implantation, previous congestive heart failure, MVD, and age ≥75 years were independent predictors of one-year MACE. Conclusions Our study shows that R-ZES has an excellent 1-year clinical outcome in Korean patients with DLCAD.

Background The self-expandable COMPLETE™ stent (Medtronic) has greater elasticity, allowing it to regain its shape after the compression force reduces, and has higher trackability, thus is easier to maneuver through tortuous vessels, whereas the balloon-expandable SCUBA™ stent (Medtronic) has higher radial stiffness and can afford more accurate placement without geographic miss, which is important in aortoiliac bifurcation lesions. To date, there have been no randomized control trials comparing efficacy and safety between the self-expanding stent and balloon-expandable stent in advanced atherosclerotic iliac artery disease. Methods/design The purpose of our study is to examine primary patency (efficacy) and incidence of stent fracture and geographic miss (safety) between two different major representative stents, the self-expanding nitinol stent (COMPLETE-SE™) and the balloon-expanding cobalt-chromium stent (SCUBA™), in stenotic or occlusive iliac arterial lesions. This trial is designed as a prospective, randomized, multicenter trial to demonstrate a noninferiority of SCUBA™ stent to COMPLETE-SE™ stent following balloon angioplasty in iliac arterial lesions, and a total of 280 patients will be enrolled. The primary end point of this study is the rate of primary patency in the treated segment at 12 months after intervention as determined by catheter angiography, computed tomography angiography, or duplex ultrasound. Discussion The SENS-ILIAC trial will give powerful insight into whether the stent choice according to deployment mechanics would impact stent patency, geographic miss, or stent fracture in patients undergoing stent implantation in iliac artery lesions.

At present, the issues of most importance are the environment and fuel efficiency. Thus, automobile companies have endeavored to reduce the weight of cars and develop eco-friendly fuel. The other issue is for the safety of passengers. Especially the new NCAP and IIHS’s regulations involving roof crash test have strengthened for a few years. The automobile indutry should increase the weight of cars for the improved regulation for the safety of passengers. OEMs have to satisfy the two confrontational requirements as developing the new vehicle. Therefore this paper will present the way to fulfill the confrontational goal by making a new B pillar structure through TRIZ and adjusting 980 Mpa high strengthened steel into the Center Pillar Outer.

Intravascular ultrasonography (IVUS) imaging is a user-friendly technique widely used during coronary interventions. An 80-year-old man was admitted with chest pain, and successful percutaneous coronary intervention was performed with stent implantation. One week later, the patient complained of further chest pain. Urgent coronary angiography showed total occlusion of the middle left anterior descending artery and the aspiration of thrombi was high. IVUS imaging showed inadequate stent strut apposition and distal dissection. We attempted another stent implantation but the IVUS catheter was stuck on the 0.014 inch wire. Therefore, we tried to pass the wire across the lateral side. After the wire was successfully passaged, the sprinter balloon was passed through the crushed stent to expand it. After 4 days later, the patient was discharged with no symptoms or electrocardiographic change.

Concurrent cerebral and coronary artery embolization is a theoretically possible, but extremely rare complication of an atrial myxoma. We present a paitent with a left atrial mass (a probable myxoma) who presented with concurrent cerebral and myocardial infarctions due to emboli of tumor origin. An 84-year-old woman presented with an acute cerebral infarction of the middle cerebral artery territory. Several hours after admission, she complained of chest pain consistent with a myocardial infarction. Transthoracic and transesophageal echocardiographic studies revealed the presence of a large, mobile, heteroechoic mass with a few daughter nodules in the left atrium, compatible with a myxoma. Coronary angiography disclosed subtotal occlusion of the ramus intermedius branch and visible tumor vascularization adjacent to the right coronary artery. With medical treatment, including anticoagulation, the patient was stabilized and had an uneventful clinical course for the ensuing 6 months since discharge. (Korean Circ J 2008;38:622-626)

Introduction Spontaneous native aortic valve thrombosis is a rare condition. Almost all published cases have been associated with heart valve disease, heart valve replacement, a hypercoagulative state or the presence of an autoimmune disease. The present case is unique in that a thrombus developed on a native aortic valve with no predisposing cause, which resulted in a potentially fatal embolism to a coronary artery.
