Isolated congenital aneurysm of the left atrium with intact pericardium is a rate anomaly, which usually presents with arrhythmia, cerebral embolism or abnormalities on routine chest X-ray. Surgery is indicated in most cases to eliminate a potential source of systemic emboli and arrhythmias. A 42-year-old woman having cervical cancer, she was suspected of having a left atrial aneurysm on review of chest X-ray and confirmed by echocardiography and cardiac catheterization. Surgical resection of Left atrial aneurysm was achieved without complication using median sternotomy with cardiopulmonary bypass. The postoperative course was uneventful.

Cardiomyopathies were previously defined as "an idiopathic myocardial disease that is not secondary to any other type of congenital/acquired heart disease or systemic diseases." With increasing understanding of etiology and pathogenesis in human medicine, the difference between cardiomyopathy and specific heart muscle disease has become indistinct. Cardiomyopathies are now classified by the dominant pathophysiology or, if possible, by etiological/pathogenetic factors. The American Heart Association recently advocated the following new definition of cardiomyopathy: Cardiomyopathies are a heterogeneous group of diseases of the myocardium associated with mechanical and/or electrical dysfunction that usually (but not invariably) exhibit inappropriate ventricular hypertrophy or dilatation and are due to a variety of causes that frequently are genetic. Cardiomyopathies either are confined to the heart or are part of generalized systemic disorders, often leading to cardiovascular death or progressive heart failure-related disability. Because the understanding of etiology or pathogenesis of cardiomyopathy has been limited in veterinary medicine, the previous classification is generally used. It is considered a dilated, hypertrophic and restrictive group on the basis of the predominant morphological and functional abnormalities. In addition, arrhythmogenic right ventricular cardiomyopathy and unclassified cardiomyopathy were also recognized in dogs and/or cats.

The incidences of cardiovascular diseases are rapidly increasing worldwide. The electrocardiogram (ECG) is a test to detect and monitor heart issues via electric signals in the heart. Presently, detecting heart disease in real time is not only possible but also easy using the myDAQ data acquisition device and LabVIEW. Hence, this paper proposes a system that can acquire ECG signals in real time, as well as detect heart abnormalities, and through light-emitting diodes (LEDs) it can simultaneously reveal whether a particular waveform is in range or otherwise. The main hardware components used in the system are the myDAQ device, Vernier adapter, and ECG sensor, which are connected to ECG monitoring electrodes for data acquisition from the human body, while further processing is accomplished using the LabVIEW software. In the Results section, the proposed system is compared with some other studies based on the features detected. This system is tested on 10 randomly selected people, and the results are presented in the Simulation Results section.

Abnormalities of ventral foregut budding have been classified as "Bronchopulmonary Foregut Malformation[BPFM]". Two cases of this unusual malformation are presented. The first case was that of a 48-year-old male with a history of hemoptysis and fever. He had intralobar sequestration, located in the right lower lobe and the posterior segment of the right upper lobe, communicated with the lower esophageal fistula. The sequestrated lobe received its blood supply from anormalous feeding artery from the descending thoracic aorta. The second case was that of a 42-year-old woman with intralobar sequestration that communicated with the lower esophagus. The intralobar sequestration was located in the superior segment of the right lower lobe, and in this case, the abnormal feeding artery could not be found. In both cases, there were no other combined congenital anomalies. They were managed with surgical resection successfully and followed up without any significant complications.lications.

Congenital esophageal stenosis is a rare disease in childhood. By virtue of its complex embryological development, the esophagus is the site of many congenital abnormalities. Congenital Esophageal stenosis is one tenth as rare as tracheoesophageal fistula with esophageal atresia and is very rare in the cervical esophagus, which mostly occurred below mid-esophagus. Congenital esophageal web may be caused by the resorption failure of the epithelium following the vacuolization stage in embryonic development in the esophagus. Recently, we experienced 1 cases of congenital esophageal web, as the symptoms of life-long dysphagia. According to her history of dysphagia, radiologic and clinical findings, her esophageal stenosis was considered as congenital. For dilatation and relief of dysphagia, she underwent the Heineke-Mikulicz type of esophagoplasty. The results of surgical treatment were relatively good without any clinical events. So we reported it with its literature review.

We experienced primary repair of complete atrioventricular septal defect with Teralogy of Fallot. The diagnosis was established preoperatively by echocardiography, cardiac catheterization and cardioangiography. Repair was accomplished using cardiopulmonary bypass. Two patch techinque were performed using Dacron patch for ventricular septal defect and pericardial patch for atrial septal defect. Infundibullectomy and right ventricular outflow tract reconstruction with the transannular pericardial patch were performed. The postoperative echocardiography showed mild mitral and tricuspid regurgitation, but there were no hemodynamic abnormalities.

Traumatic spinal cord infarction is a rare condition that causes serious paralysis. The regulation of spinal cord blood flow in injured spinal cords remains unknown. Spinal cord infarction or ischemia has been reported after cardiovascular interventions, scoliosis correction, or profound hypotension. In this case, a 52-year-old man revisited the emergency center with motor and sensory abnormalities in all four extremities 56 hours after a motor vehicle collision. Despite the clinical presentation and imaging examination, there were no specific findings on the patient's first visit to the trauma center. Cervical spine computed tomography angiography showed a narrow vertebral artery, and diffusion-weighted imaging revealed spinal cord infarction from C3 to C5 with high signal intensity. It should be kept in mind that delayed-onset spinal cord infarction may occur in minor or major trauma patients as a result of head and neck injuries.

Unlike studies of Europeans and Americans, many epidemiological studies of the Korean population have indicated that their risk for cardiovascular disease does not decrease with a vegetable-rich diet. The different dietary practices of Koreans, who consume salted vegetables instead of fresh vegetables (common in the Western diet), has been suggested as a reason for this observation. Korea is in a period of rapid epidemiologic transition, which includes dietary and disease patterns; therefore, this study investigated differences in the food consumption pattern and blood lipid profiles of Koreans compared to Europeans and Americans. The identification of dietary patterns related to blood lipid abnormalities was carried out using the 2007~2009 Korean National Health and Nutrition Survey data from 14,056 subjects. Dietary patterns were analyzed according to food group and nutrient intake. Blood lipid abnormalities were classified into three groups: hypercholesterolemia, hypertriglyceridemia, and low HDL cholesterolemia (hypo-HDL-cholesterolemia). The prevalence of hypercholesterolemia, hypertriglyceridemia, and hypo-HDL-cholesterolemia was 12.4%, 16.2%, and 27.7% respectively. In our analysis, the low consumption of all food groups was related to hypercholesterolemia. The high consumption of vegetable-containing foods, alcoholic beverages, and the low consumption of milk products were associated with hypertriglyceridemia and hypo-HDL-cholesterolemia. Thus, unlike Europeans and Americans, the low consumption of all food groups is related to hypercholesterolemia and a low consumption of milk products is related to hypertriglyceridemia and hypo-HDL-cholesterolemia. Dietary pattern might play a role in epidemiologic transition of Korean. Also, this study implies necessity of further research using longitudinal data.

Objective: Combined oral contraceptives (COCs) have some adverse effects on the serum lipid profile. Because hyperlipidemia is one of the risk factors in cardiovascular diseases, lipid abnormalities should be evaluated in women consuming COCs. Vitamins E and C are known to have beneficial effects on serum lipid profiles. Therefore, in this study, we evaluated the effects of vitamins E and C on serum lipids in women using COCs. Methods: The study compared changes in lipid parameters with and without vitamin therapy in women consuming COCs compared to those of a control group (40 non-contraceptive users or NCU) for 4 weeks. Total cholesterol and triglyceride, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) levels along with HDL/LDL ratios were measured for all participants. Results: COC users experienced significantly higher increases in the levels of triglycerides and LDL than non-users (p<0.05). However, no significant differences were noted in the total cholesterol and HDL levels. In the treated COC group receiving vitamins E and C, the HDL level and the HDL/LDL ratio increased and the LDL and triglycerides levels decreased significantly compared with those of the other groups. Conclusion: The results of our study indicate that supplementation with antioxidant vitamins E and C restores a normal lipid profile in COC users.
