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.

Purpose: The purpose of this study was to identify the effect of exercise therapy on low back pain, self-urination disorder, bleeding, and hematoma in Percutaneous Coronary Intervention (PCI) patients. Methods: A total of 64 PCI patients were recruited from C hospital located in C city, from June until August of 2010. The patients were divided into two groups as the exercise and control group. Thirty-two participants in the exercise group took bedrest for two hours after PCI, and then received excise therapy. The other 32 participants in the control group took the usual 8-hour bedrest with intermittent back care by the unit nurses. Results: In the relieving effect of low back pain, exercise group reported pain reduced faster than the control group. On the other hand, there were no significant differences between the two groups in alleviant of self-urination disorder, bleeding, and hematoma. Conclusion: Exercise therapy for reducing patients' low back pain showed to be an effective nursing intervention. Since there was no bleeding or hematoma after PCI in the exercise group, this study provided the ground suggesting that it might be possible to reduce the bedrest time after PCI without increased risk of bleeding or hematoma.

Stent entrapment is a very rare complication of percutaneous coronary intervention. The interventional approach could be a treatment strategy. However, if it does not work, surgical treatment should be considered. Here, we report a case of surgical treatment of stent entrapment in the left coronary sinus of a 53-year-old male patient.

Restenosis remains a major limitation of percutaneous coronary interventions. Numerous studios including pharmacological approaches and new devices failed to reduce the restenosis rate except coronary stenting. Since the results of $BENESTENT^{1)}\;and\;STRESS^{2)}$ studies came out, coronary stenting has been the most popular interventional strategy in the various kinds of coronary stenotic lesions, although the efficacy of stenting was shown only in the discrete lesion of the large coronary artery. The widespread use of coronary stenting has improved the early and late outcomes after coronary intervention, but it has also led to a new and serious problem, e.g., in-stent restenosis. Intravascular radiation for prevention of restenosis is a new technology in the field of percutaneous coronary intervention. Recent animal experiments and human trials have demonstrated that local irradiation, in conjunction with coronary interventions, substantially diminished the rate of restenosis. This paper reviews basic radiation biology of intracoronary radiation and its role in the inhibition of restenosis. The current status of intracoronary radiation therapy using Re-188 liquid balloon is also discussed.

Coronary arterial involvement in Takayasu arteritis (TA) is not uncommon. Herein, we describe a case of TA with celiac trunk and superior mesenteric artery occlusion combined with coronary artery disease. Bilateral huge internal thoracic arteries (ITAs) and the inferior mesenteric artery provided the major visceral collateral circulation. After percutaneous intervention to the right coronary artery, off-pump coronary artery bypass grafting for the left coronary territory was done using a right ITA graft and its large side branch because of its relatively minor contribution to the visceral collateral circulation.

Purpose: The purpose of this study was to explore the differences of health locus of control and treatment compliance according to general characteristics and severity in acute coronary syndrome(ACS) patients after percutaneous coronary intervention. Methods: This descriptive study was conducted with a convenient sample of 103 ACS patients. The dependent variables were measured by the scales for the Multidimensional Health Locus of Control and the Treatment Compliance. The collected data were analyzed by the Fisher's exact test, Chi-square and t-tests, and ANOVA using the SPSS program. Results: Pre-interventional severity was significantly different between men and women. In terms of internal health locus of control, there was a significant difference according to gender, educational status, economic status, and severity. The level of medication compliance was the lowest among the sub-scales of treatment compliance. Conclusion: These findings suggest that clinical nurses should evaluate the general characteristics and severity of the patients with ACS for providing tailored nursing interventions.

Background: Coronary angioplasty has been replacing coronary artery bypass grafting (CABG) because of the relative advantage in terms of recovery time and noninvasiveness of the procedure. Compared to other Organization for Economic Cooperation and Development (OECD) countries, Korea has experienced a rapid increase in coronary angioplasty volumes. Methods: We analyzed changes in procedure volumes of CABG and of percutaneous coronary intervention (PCI) from three sources: the OECD Health Data, the National Health Insurance Service (NHIS) surgery statistics, and the National Health Insurance claims data. Results: We found the ratio of procedure volume of PCI to that of CABG per 100,000 population was 19.12 in 2014, which was more than triple the OECD average of 5.92 for the same year. According to data from NHIS statistics, this ratio was an increase from 11.4 to 19.3 between 2006 and 2013. Conclusion: We found that Korea has a higher ratio of total procedure volumes of PCI with respect to CABG and also a more rapid increase of volumes of PCI than other countries. Prospective studies are required to determine whether this increase in absolute volumes of PCI is a natural response to a real medical need or representative of medical overuse.

Patients with anomalous connection of the left coronary artery to the pulmonary artery are at risk for myocardial infarction, and early or sudden death. Between 1986 to 1992, a total of 4 of these patients underwent surgical intervention with various operative techniques at our institution. Age at operation ranged from 2 months to 43 years. Three infant patients had congestive heart failure, 2 of them had mitral regurgitaion, and 1 had ST-T change on elctrocardiogram. Operative techniques included direct coronary artery transfer to the aorta[n=2], intrapulmonary tunnel from the aortopulmonary window[n=1], coronary artery bypass using saphenous vein[n=1]. One deaths occured at 2 weeks after direct coronary arterial transfer due to respiratory failure caused by Respiratory Syncitial virus pneumonia. Supravalvar pulmoanry stenosis occured after intrapulmoanry tunnel. We recommend direct aortic implatation of the anomalous coronary artery at the time of diagnosis. Intrapulmonary tunnel from aortopulmonary window or subclavian-coronary anastomosis could be alternatives in whom aortic implantation is not feasible anatomically.

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.

Background: This study investigates the potential volume and outcome association of coronary heart disease (CHD) patients who have undergone percutaneous coronary intervention (PCI) using a large and representative sample. Methods: We used a National Health Insurance Service-Cohort Sample Database from 2002 to 2013 released by the Korean National Health Insurance Service. A total of 8,908 subjects were analyzed. The primary analysis was based on Cox proportional hazards models to examine our hypothesis. Results: After adjusting for confounders, the hazard ratio of thirty-day and 1-year mortality in hospitals with a low volume of CHD patients with PCI was 2.8 and 2.2 times higher (p=0.00) compared to hospitals with a high volume of CHD patients with PCI, respectively. Thirty-day and 1-year mortality of CHD patients with PCI in low-volume hospitals admitted through the emergency room were 3.101 (p=0.00) and 2.8 times higher (p=0.01) than those in high-volume hospitals, respectively. Only 30-day mortality in low-volume hospitals of angina pectoris and myocardial infarction patients with PCI was 5.3 and 2.4 times those in high-volume hospitals with PCI, respectively. Conclusion: Mortality was significantly lower when PCI was performed in a high-volume hospital than in a low-volume hospital. Among patients admitted through the emergency room and diagnosed with angina pectoris, total PCI volume (low vs. high) was associated with significantly greater cardiac mortality risk of CHD patients. Thus, There is a need for better strategic approaches from both clinical and health policy standpoints for treatment of CHD patients.
