Coronary artery involvement and myocardial ischemic symptom in Takayasu`s arteritis is uncommon Its presentation as coronary artery narrowing is a potentially lethal but correctable problem. In this case report, a 17-year-old woman of Takayasu`s arteritis with unstable anginal and moderate heart failure is presented. Her coronary angiogram showed that the main trunk of the left coronary artery was moderately narrowed and the proximal portion of the circumflex branch was severely obstructed and the right coronary artery was also narrowed diffusely. Simultaneously the patient had the moderate degree of mitral regurgitation. In order to save her life, the coronary bypass surgery using the saphenous veins and the modified Wooler`s mitral annuloplasty were done urgently, Immediate recovery was uneventful and the postoperative exercise capacity was markedly improved. But the long-term prognosis seems to be uncertain because of 3 reasons: 1] natural progress and complication of Takayasu`s arthritis; 2] fate of the saphenous vein grafts in a relatively young patient with aortitis; 3] residual mitral regurgitation. So long-term follow-up should be needed.

Anomalous origin of a coronary aortic artery is a rare cardiac anomaly. Although it can cause angina, syncope, and palpitations, most patients are asymptomatic. This anomaly requires surgical treatment or intervention because it is associated with sudden death. Several surgical techniques, such as coronary reimplantation, coronary artery bypass grafting (CABG), unroofing, and neo-ostium formation, have been proposed as treatments. We report a case surgically treated with neo-ostium formation in anomalous origin of the left coronary artery from the right coronary sinus.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is an extremely rare, potentially fatal, congenital anomaly with a high mortality rate in the first year of life. It occurs rarely in adulthood and may appear with malignant ventricular arrhythmia or sudden death. We report a case of a 49-year-old woman with ALCAPA who presented with dyspnea on exertion. Management was coronary artery bypass grafting to the left anterior descending artery and obtuse marginal arteries, closure of the left main coronary artery ostium, and reestablishment of the dual coronary artery system.

Anomalous origin of left coronary artery from pulmonary artery(ALCAPA) is a rare fatal congenital anormaly that needs early surgical intervention. Many reports say that the choice of operative procedure is reimplantation of the left coronary artery into the ascending aorta. We experienced the surgical management of a case of the ALCAPA. The patient was 44 days old and 3.45 kg weighed female baby who had a symptom of congest ve heart failure. She underwent implantation of coronary artery on the aorta with cardiopulmonary bypass and recovered without any complications.

This study was performed to investigate the hemodynamic changes which occur after occlusion of coronary artery and relation to reperfusion arrhythmias(RA) which occur when occlusion materials were removed form coronary artery in dogs. The occlusion of coronary artery was designed by temporary ligation of left circumflex branch of coronary artery during 30 minutes in 16 dogs. During occlusion of coronary artery, cardiac output(CO), mean aortic pressure (mAP), aortic systolic pressure(ASP), aortic diastolic pressure(ADP). left ventricular systolic pressure(LVSP), left ventricular maximum dp/dt (LV max. dp/dt) and left ventricular end-diastolic pressure (LVEDP) were measured. The occurrence of RA were observed for 5 minute after reperfusion by explained of ligation. As a results, cardiac arrest occurred in 4 dogs during occlusion of coronary artery, and RA was not observed in 5 dogs while it was seen in 5 dogs when explained ligation(reperfusion) after 30 minutes, the rest 2 dogs occurred temporary tachycardia. In hemodynamics changes, LVSP decreased by 10.9% and LV max. dp/dt by 5.4 % in comparison to control value which not ligated coronary artery, and LVEDP increased by 73.3%. The CO/min and mAP also decreased by 10.7% and by 11.3% expectedly. In the relationship to occurrence RA and hemodynamics changes, the LVSP and LV max. dp/dt at the time of occlusion in the RA group decreased by 11.9% and 0.8% in comarison to the control value while the decrease was 7.7% and 10% in the non-RA group. But the LVEDP in creased by 109.1% in the RA group while the decreased was 44.6% in the non-RA group. Referring CO/min, the drop was 8.8% in the RA occurrence group and 12.9% in the non-occurence group. These parameters of LVEDP, LV max. dp/dt, and CO were significant difference(p<0.05). The mAP also decreased by 11.9 in the RA group and by 9.8% in the non-RA group, but these defference were not the significant difference.

Myocardial abscess usually occurs as a complication of infective endocarditis or overwhelming septicemia. Coronary artery occlusion caused by myocardial abscess has been rarely reported. A 61-year-old man presented with fever and chill that developed 6 weeks prior to admission. He had a history of cardiopulmonary resuscitation for ventricular fibrillation and cardiac arrest 4 weeks prior to admission. Echocardiography showed a 3xfcm sized mass in the area of the right atrioventricular groove and coronary angiography showed complete occlusion of the proximal right coronary artery. Under the diagnosis of myocardial infarction complicating myocardial abscess, debridement of abscess and coronary artery bypass grafting with right internal mammary artery to distal right coronary artery was performed. Culture from the abscess cavity demonstrated Salmonella arizona.

Purpose: This study aimed to identify latent classes based on major modifiable risk factors for coronary artery disease. Methods: This was a secondary analysis using data from the electronic medical records of 2,022 patients, who were newly diagnosed with coronary artery disease at a university medical center, from January 2010 to December 2015. Data were analyzed using SPSS version 20.0 for descriptive analysis and Mplus version 7.4 for latent class analysis. Results: Four latent classes of risk factors for coronary artery disease were identified in the final model: 'smoking-drinking', 'high-risk for dyslipidemia', 'high-risk for metabolic syndrome', and 'high-risk for diabetes and malnutrition'. The likelihood of these latent classes varied significantly based on socio-demographic characteristics, including age, gender, educational level, and occupation. Conclusion: The results showed significant heterogeneity in the pattern of risk factors for coronary artery disease. These findings provide helpful data to develop intervention strategies for the effective prevention of coronary artery disease. Specific characteristics depending on the subpopulation should be considered during the development of interventions.

A case of a single coronary artery complicated with a coronary artery fistula (CAF) to the right ventricle is extremely rare, and its management strategy and prognosis are not clear. A 5-year-old boy was hospitalized for evaluation of a continuous heart murmur. Transthoracic echocardiography suggested a CAF to the right ventricle, with an enlarged left coronary artery. Cardiac catheterization confirmed the CAF terminating at the right ventricle and the absence of a right coronary artery. The fistula was ligated at the right ventricular side under cardiopulmonary bypass. At follow-up 18 months later, the child was clinically asymptomatic, and coronary angiogram showed no recurrence of the fistula.

Purpose: The purpose of this study was to determine the effect of supportive nursing care on the level of knowledge and compliance with sick-role behavior in patients with coronary artery disease after coronary angiography (CAG). Methods: A quasi-experimental research was performed with 81 subjects with coronary artery disease who were admitted for CAG to a cardiovascular department. Among the selected subjects, 40 of them were assigned to experimental group and the rest of them were assigned to control group by convenience. Supportive nursing care was implemented twice by a researcher. Results: 1. The mean score of knowledge related to coronary artery disease was higher in the group who received supportive nursing care than that of the control group (t=2.259, p=.027). 2. The mean score of compliance of sick role behavior was higher in the group who received supportive nursing care than that of the control group (t=4.580, p=.001). Conclusion: The supportive nursing care after CAG was effective in increasing the knowledge level and compliance of sick-role behavior in patients with coronary artery disease. Further studies would be recommended to identify long-term effectiveness of supportive care on patients' outcomes.

Forty cases of coronary artery bypass grafting treated at the Department of Thoracic and Cardiovascular Surgery, SNUH, Korea were compared with forty cases of the procedure treated at University of Alberta Hospital, Canada, in terms of pathoanatomy. That showed no difference in sex ratio between Korean and Caucasian the average ages, however, were 50.4 years and 60.9 years respectively [p< 0.005]. The leading cause of angina at presentation was unstable angina in Korean, but it was post-infarction angina in Caucasian instead. The incidences of single-vessel disease and double-vessel disease were similar in both countries, but the incidence of so-called triple-vessel disease was higher in Caucasian while left main coronary artery disease was more prevalent in Korean [0.01< P, 0.005]. < The internal diameters of surgically available coronary artery branches had similar characteristics and no significant statistical differences were found between them. The predilection sites of stenoses were proximal left anterior descending artery, left main coronary artery, proximal left circumflex artery and proximal right coronary artery decreasing in incidence respectively, in Korean. The myocardial perfusion score were 6.80 in single-vessel disease, 7.56 in double-vessel disease, 11.27 in triple-vessel disease and 9.77 in left main disease respectively, in Korean.
