  • Castleman disease is a relatively rare disease, characterized by well-circumscribed benign lymph-node hyperplasia. The disease may develop anywhere in the lymphatic system, but is most commonly reported as unicentric Castleman disease in the mediastinum along the tracheobronchial tree. It is usually asymptomatic and detected on plain chest radiography as an incidental finding. We report an incidentally detected case of Castleman disease in the paravertebral space that was preoperatively diagnosed as a neurogenic tumor and treated by complete surgical resection.

  • Pulmonary arteriovenous fistula (PAVF) is a complication of the Glenn shunt. A 57-year-old tetralogy of Fallot (TOF) patient, who had undergone a Glenn shunt and TOF total correction, complained of dyspnea and cyanosis. PAVFs were present in the rig ht lung, and rig ht lung perfusion was nearly absent. After coil embolization, takedown of the Glenn shunt, and reconstruction of the rig ht pulmonary artery, the patient's symptoms were relieved. Extrapulmonary radioisotope uptake caused by the PAVFs shown in lung perfusion scans decreased, and right lung perfusion increased gradually. Although the development and resolution of PAVFs after a Glenn shunt have been reported in the pediatric population, this may be the first report on this change in old age.

  • Objectives: Existing cardiovascular simulators are used to evaluate artificial organs such as artificial hearts, prosthetic valves, and artificial blood vessels, and pulses are typically triggered using artificial hearts. However, the forms of pulse waves vary according to the location of arteries, and for precise assessment of artificial blood vessels, the development of simulators that generate diverse pressure pulse waves is necessary. This study developed a novel cardiovascular simulator that generates different forms of pulse waves. Methods: This simulator consists of a stepping motor, a slider-crank mechanism that transforms the rotation movement of a motor into the straight-line motion of a piston, a piston that generates pulsatile flows, a water tank that supplies fluids, an elastic tube made of silicon, and a device that adjusts the terminal resistance of fluids. Results & Conclusion: This study examined motor rotation and its operation under conditions similar to the physiological conditions of the heart. The simulator developed in this study produced diverse forms of waves, and the generated pressure waves well satisfied physiological conditions.

  • Purpose: To determine the degree of cardiovascular disease risk according to socioeconomic factors among midlife women in the community and thereby provide baseline data for the development of health promotion programs. Method: A total of 200 women participated in health screenings and a health survey. The survey was performed in November and December, 2006. The survey instruments included socioeconomic factors, health behavior (smoking and exercise), and family history. Biophysical measurement included BMI and blood pressure. Blood samples were drawn for glucose and total cholesterol tests. Results: The mean age was 52.5 years, 34.0% had received education less than 6 years, 70.0% earned a monthly income of less than \1,500,000, and 61.5% were homemakers. Cardiovascular disease risk was significantly different by age (BMI, systolic BP, and exercise), education (systolic BP), monthly income (T. cholesterol), marital status (smoking), and occupation (exercise). Most women had 2 or 3 cardiovascular disease risks. Older age, lower education, and lower income were significantly associated with increased cardiovascular disease risk. Conclusion: Efforts should be made to decrease the number and severity of cardiovascular disease risk factors for midlife women in the community by developing health promotion programs targeting to modify their cardiovascular disease risk factors.

  • Background: The purpose of this study is to evaluate the concentration of cardiovascular surgical procedures in a metropolitan area and investigate the perception of specialists regarding governmental policies to resolve this imbalance. Methods: From March to May 2015, surveys were distributed to members of the Thoracic and Cardiovascular Surgery Association. The final pool of research subjects consisted of 75 respondents. Subjects were queried regarding the concentration of cardiovascular operations in metropolitan areas, alternatives to the imbalance, and governmental policies to resolve the inequalities. Results: Survey participants responded that South Korea needs governmental policies to alleviate the concentration of cardiovascular surgery patients in large metropolitan hospitals. Participants agreed that the freedom to choose medical institutions and improved accessibility to metropolitan hospitals due to advanced transportation systems were some of the causes for the concentration. A majority (98.7%) of respondents thought establishing thoracic and cardiovascular surgery centers in provinces was an appropriate solution to alleviate the concentration. Thoracic and cardiovascular surgery specialists were ranked as the number one group on which to focus development. Conclusion: Developing and carrying out policies to establish thoracic and cardiovascular surgery centers in provinces will alleviate the regional imbalance in available heart surgery services and an overall improvement in cardiovascular disease treatment in South Korea.

  • A rare anomaly, Cor triatriatum dexter combined with pulmonary stenosis and patent foramen ovale in a 2-years- old female is presented. Abnormal embryologic development of the right sinus venosus valve caused partial membranous septation of the right atrium. Most cases have been recorded at necropsy either as an incidental finding or in association with severe congenital heart disease. In this case, Cor triatriatum dexter was diagnosed preoperatively by cineangiography and echocardiography.

  • Molecular imaging strives to visualize processes in living subjects at the molecular level. Monitoring biochemical processes at this level will allow us to directly track biological processes and signaling events that lead to pathophysiological abnormalities, and help make personalized medicine a reality by allowing evaluation of therapeutic efficacies on an individual basis. Although most molecular imaging techniques emerged from the field of oncology, they have now gradually gained acceptance by the cardiovascular community. Hence, the availability of dedicated high-resolution small animal imaging systems and specific targeting imaging probes is now enhancing our understanding of cardiovascular diseases and expediting the development of newer therapies. Examples include imaging approaches to evaluate and track the progress of recent genetic and cellular therapies for treatment of myocardial ischemia. Other areas include in vivo monitoring of such key molecular processes as angiogenesis and apoptosis, Cardiovascular molecular imaging is already an important research tool in preclinical experiments. The challenge that lies ahead is to implement these techniques into the clinics so that they may help fulfill the promise of molecular therapies and personalized medicine, as well as to resolve disappointments and controversies surrounding the field.

  • Purpose: The purpose of this study was to develop a Cardiovascular Disease Resilience (CDR) scale to evaluate disease specific resilience for recovery. Methods: The study was conducted as follows: items generation, and test of validity and reliability. Items were developed via literature review, review of instruments, and data acquired from the interviews. In order to test validity and reliability, seven panels of experts reviewed the preliminary questionnaire and then data were collected from 550 cardiovascular disease patients. Factor analysis, Pearson correlation, ANOVA, and Cronbach's alpha were used to analyze the data. Results: In the preliminary stage, forty-four items were generated. A reduction to 40 items was accomplished through content validity analysis. Factor analysis extracted 7 factors with a total of 25 items. The CDR items were moderately correlated with the subscales of the CD-RISC (Connor-Davidson Resilience Scale) and the mean score of CDR was associated with quality of life measured with CD-QOL (Cardiovascular Disease Quality of Life). Cronbach's ${\alpha}$=.84. Conclusion: Content validity, construct validity, criterion validity, and reliability of the CDR were established. The CDR is a reliable and valid instrument which the resilience of cardiovascular disease specific recovery state can be evaluated.

  • Congenital atresia of the left main coronary artery (LMCA) is an extremely rare coronary anomaly that necessitates surgical correction. Patients with LMCA atresia may have various clinical symptoms, which are determined by the degree of collateral vessel development from the right coronary system, the metabolic demands of the heart, and concomitant mitral insufficiency caused by myocardial ischemia. Unlike in adults, there are limited surgical options for coronary artery disease in children. Herein, we report a case of LMCA atresia with mitral regurgitation in a 19-month-old child that was successfully corrected by coronary artery bypass grafting and mitral valve repair.
