Transcatheter closure of atrial septal defects has become a popular procedure. The availability of a preprocedural imaging study is crucial for a safe and successful closure. Both the anatomy and morphology of the defect should be precisely evaluated before the procedure. Three-dimensional (3D) echocardiography and cardiac computed tomography are helpful for understanding the morphology of a defect, which is important because different defect morphologies could variously impact the results. During the procedure, real-time 3D echocardiography can be used to guide an accurate closure. The safety and efficiency of transcatheter closures of atrial septal defects could be improved through the use of detailed imaging studies.

Ventricular septal defects (VSDs) are the most common kind of congenital heart disease and, if indicated, surgical closure has been accepted as a gold-standard treatment. However, as lessinvasive methods are preferred, percutaneous device closure has been developed. After the first VSD closure was performed percutaneously by Lock in 1988, both techniques and devices have developed consistently. A perventricular approach for closure of muscular VSD in small patients and the closure of perimembranous VSD using off-label devices are key remarkable developments. Even though the Amplatzer membranous VSD occluder (Abbott) could not be approved for use due to the high complete atrioventricular conduction block rate, other new devices have shown good results for closure of perimembranous VSDs. However, the transcatheter technique is slightly complicated to perform, and concerns about conduction problems after VSD closure with devices remain. There have been a few reports demonstrating successful closure of subarterial-type VSDs with Amplatzer devices, but long-term issues involving aortic valve damage have not been explored yet. In conclusion, transcatheter VSD closure should be accepted as being as effective and safe as surgery but should only be performed by experienced persons and in specialized institutes because the procedure is complex and requires different techniques. To avoid serious complications, identifying appropriate patient candidates for device closure before the procedure is very important.

PURPOSE: Myocardial infarction in children with total occlusion of a coronary artery after Kawasaki disease is rare due to multiple collateral vessels. We aimed to investigate the changes in coronary perfusion associated with coronary artery occlusion after Kawasaki disease. MATERIALS AND METHODS: Eleven patients with coronary artery occlusion after Kawasaki disease were investigated. Serial coronary angiographies after total occlusion of a coronary artery were reviewed and the changes were described in all patients with additive information collected. RESULTS: The median age at the occlusion was 5.9 years old. The interval to occlusion was 6.2+/-6.9 years. Four left anterior descending coronary artery total occlusions and 10 right coronary artery total occlusions were detected. Immediate coronary artery bypass graft for left anterior descending coronary artery total occlusion made right coronary total occlusion occurred in all except one patient and the intervals thereof were 1 year, 1.8 years, and 4 years. Collaterals to the left coronary artery regressed after recanalization, while new collaterals to the right coronary artery developed. In three, collaterals to the right coronary artery decreased without recanalization without clinical signs. CONCLUSION: The right coronary artery should be followed up carefully because of possible occlusion of new onset or changes in collaterals.

Purpose: In this study, we examined change in the number of cataract surgeries from 2013 to 2018, since the implementation of institutional changes in 2012, and the introduction of diagnosis-related groups (DRGs) and a gradual reduction in selective-medical expenses from 2014. Methods: Based on data from the main surgery statistical yearbook provided by the Korea National Health Insurance Service (KNHIS), we extracted the number of cataract surgeries nationwide by year from 2013 to 2018. Data were divided by sex, age, regions, and level of healthcare providers in an effort to understand changes that occurred in the number of cataract surgeries and the reasons for these changes. Statistical analysis was carried out using joint point regression. Results: The total number of cataract surgeries per 100,000 people increased by 32.9% over the six-year period, with an annual average increase of 5.9%. Females (58.0-59.2%) had more cataract surgeries than males (40.8-42.0%). Additionally, the number of cataract surgeries per 100,000 people rose over the six-year time frame for those aged under 40 years, and for those in their 40s, 50s, and 60s. In terms of regions and patients’ residence, urban areas such as Seoul, Pusan, and Daegu showed an increase in surgeries performed; most provinces, however, with the exception of Jeju Island, indicated a relative decline in cataract surgeries. There was no difference in the number of cataract surgeries performed over the six-year period in terms of the level of healthcare providers. Conclusions The number of cataract surgeries per 100,000 people rose over the six-year period between 2013 and 2018. By region, an increasing trend was observed in urban areas; however, the level of the healthcare providers did not appear to have an effect on the number of cataract surgeries performed.

OBJECTIVE: To investigate the effects of glenohumeral internal rotation deficit (GIRD) on the isokinetic strength, body pain, and the quality of life in male high school baseball players of Korea. METHODS: Fifty-six male high school baseball players were divided into either group A (GIRD> or =20degrees, n=12) or group B (GIRD<20degrees, n=44). The range of motion in the shoulder and the isokinetic strength were measured. Questionnaires were administered regarding the body pain location by using the visual analogue scale, and the quality of life was measured by using the SF-36 Form. RESULTS: All subjects had increased external rotation range of motion and decreased internal rotation in the throwing shoulder. The incidence of GIRD (> or =20degrees) was 21.43% in the present study. In the isokinetic strength test, a significantly weaker muscular state at an angular velocity of 180degrees/s was observed in group A, compared to group B. For the comparison of the pain, the frequency of shoulder pain was higher (33.93%) than other body pain, among the study subjects. CONCLUSION: GIRD is one of the main risk factors of glenohumeral joint damage, and it is correlated with reduced isokinetic strength and quality of life. High school baseball players will need appropriate shoulder rehabilitation programs for the improvement in their quality of life and performance.

Brugada syndrome is a rare channelopathy associated with the SCN5A gene that causes fatal ventricular arrhythmias. This case of Brugada syndrome, in which ventricular tachycardia (VT) was provoked by high fever, is the first report in a Korean child. The boy had retinoblastoma of his left eye diagnosed at 16 months of age. After chemotherapy, he contracted a catheter-related infection with a high fever up to 41degrees C leading to monomorphic VT. This was characterized as having right bundle branch block morphology, superior axis deviation, and a heart rate of 212/min. Direct current cardioversion recovered the VT to sinus rhythm after a lack of response to amiodarone and lidocaine. A second attack of VT that was not controlled by cardioversion, however, responded to lidocaine. The baseline electrocardiogram showed a long PR interval and QRS duration, and the patient's grandfather had a history of Brugada syndrome. A mutation in SCN5A was identified in this patient, his father, and his grandfather. The patient was treated with quinidine and followed up for 1 year.

BACKGROUND: This cross-sectional study aimed to evaluate the prevalence of depressive disorders and factors associated in long-term cancer survivors. METHODS: A total of 702 long-term cancer survivors over 5-years in remission were recruited in a university-affiliated tertiary hospital in Korea. Self-report using the Patient Health Questionnaire-2 and the Fatigue Severity Scale assessed depression and fatigue, respectively. Demographic characteristics, cancer-related clinical characteristics, comorbidity, health behaviors, and physical symptoms were assessed through the review of medical records or a structured self-administered questionnaire. RESULTS: We identified 26.1% of patients who had a depressed mood or displayed a loss of interest. The most prevalent primary site of cancer was the stomach (65.2%), followed by lung, breast, colorectal, and thyroid cancer. We also found that 5.7% of subjects experienced double or triple primary cancers. Larger proportion among depressive group (89.1%) complained at least one physical problem than among non-depressive group (53.2%). Physical symptoms including sleep problems, dry mouth, indigestion, pain, decreased appetite, and febrile sense were more frequent in the depressive group than in the non-depressive group. The Fatigue Severity Scale scores were higher in the depressive group than in the non-depressive group (P<0.001). Multiple logistic regression analysis showed that the highest tertile level of fatigue (odds ratio, 7.31; 95% confidence interval, 3.81-14.02) was associated with the increased risk of depression. CONCLUSION: These findings suggest that careful concern about depression is necessary in long-term cancer survivors. Fatigue may be a surrogate sign for depression, and warrants further evaluation.

PURPOSE: For the successful completion of transcatheter closure of atrial septal defects with the Amplatzer septal occluder, shape of the defects should be considered prior to selecting the device. The purpose of this study is to evaluate the results of a transcatheter closure of oval shaped atrial septal defect. MATERIALS AND METHODS: From November 2009 until November 2011, cardiac computed tomography was performed on 69 patients who needed a transcatheter closure of atrial septal defect. We defined an oval shaped atrial septal defect as the ratio of the shortest diameter to the longest diameter < or =0.75 measured using computed tomography. A trans-thoracic echocardiogram was performed one day after and six months after. RESULTS: The transcatheter closure of atrial septal defect was performed successfully in 24 patients in the ovoid group and 45 patients in the circular group. There were no serious complications in both groups and the complete closure rate at 6 months later was 92.3% in the ovoid group and 93.1% in the circular group (p>0.05). The differences between the device size to the longest diameter of the defect and the ratios of the device size to the longest diameter were significantly smaller in the ovoid group (1.8+/-2.8 vs. 3.7+/-2.6 and 1.1+/-0.1 vs. 1.2+/-0.2). CONCLUSION: Transcatheter closure of an oval shaped atrial septal defect was found to be safe with the smaller Amplatzer septal occluder device when compared with circular atrial septal defects.

The presence of a single coronary artery is a rare congenital anomaly; such patients often present with severe myocardial ischemia. We experienced the case of a 13-year-old girl with the right coronary artery originating from the left circumflex artery. She visited our Emergency Department owing to severe chest pain; her cardiac enzyme levels were elevated, but her initial electrocardiogram (ECG) was normal. Echocardiography showed normal anatomy and normal regional wall motion. When she presented with recurrent chest pain on admission, the ECG showed significant ST-segment elevation in the left precordial leads and inferior leads with ST-segment depression in aVR lead, suggesting myocardial ischemia, and her cardiac enzyme levels were also elevated. We performed coronary angiography that showed a single right coronary artery originating from the left circumflex artery without stenosis. We confirmed the presence of a single coronary artery using coronary computed tomography. In addition, the treadmill test that was performed showed normal results. She was discharged from the hospital without any medications but with a recommendation of a regular follow-up.
