Not a few patients in children and adolescents are suffering from right ventricular (RV) dysfunction resulting from various conditions such as chronic lung disease, left ventricular dysfunction, pulmonary hypertension, or congenital heart defect. The RV is different from the left ventricle in terms of ventricular morphology, myocardial contractile pattern and special vulnerability to the pressure overload. Right ventricular failure (RVF) can be evaluated in terms of decreased RV contractility, RV volume overload, and/or RV pressure overload. The management for RVF starts from clear understanding of the pathophysiology of RVF. In addition to correction of the underlying disease, management of RVF per se is very important. Meticulous control of volume status, inotropic agents, vasopressors, and pulmonary selective vasodilators are the main tools in the management of RVF. The relative importance of each tool depends on the individual clinical status. Medical assist device and surgery can be considered selectively in case of refractory RVF to optimal medical treatment.

Objectives: The objective of this study is to investigate and valuate currently provided database management systems (DBMS) of traditional Korean medical knowledge. Methods: We searched DBMS on the web and smart device application markets (Apple App Store and Google Play Store). Key words for searching were 'traditional medicine', 'acupuncture', 'moxibustion', 'herbal medicine', and '한의학'. We looked into each DBMS to find out its scopes and limits, and each was valuated according to its functionality, accessibility, and utility. Results: 186 DBMS of traditional Korean medical knowledge were investigated and 91% of them were applications for smart devices. Almost all DBMS provided acupuncture and herb information, and a small amount of DMBS provided prescription and research paper information. Functionality, accessibility, and utility valuation were performed by using scoring system from 0 to 2. Mean values of functionality, accessibility, and utility were 0.86, 1.29, and 1.09. Conclusions: On the whole, high accessibility and low functionality were found, and various data-calculating functions were not implemented. Further researches and developments about traditional Korean medical knowledge DBMS are necessary to provide correct traditional Korean medical information and to support the studies about Korean medicine.

Interventional device closure has emerged as a less invasive alternative to surgery in the management of paravalvular leakage. However, this procedure involves various problems such as a high probability of residual leakage or hemolysis. Here, we report a case of residual paravalvular leakage despite two attempts at interventional closure in a patient with a history of four previous mitral valve replacements. The fifth operation for the primary repair of paravalvular leakage was performed successfully. Careful evaluation before the procedure and specially designed devices are essential for the interventional treatment of paravalvular leakage. Surgery can be performed adequately in the management of paravalvular leakage even in high-risk patients.

Purpose: The I-gel device is Korea's most frequently used airway management method during pre-hospital cardiopulmonary resuscitation (CPR). This study aimed to compare changes in ventilation volume according to the fixation method with a simulated manikin. Methods: We placed I-gel into an advanced life support simulator and compared tape and band fixation conditions. CPR was performed according to the 2020 Korean CPR guidelines, using a mechanical chest compression device and an adult bag. The positional shift of I-gel and the ventilation volume of the simulated manikin were measured after performing CPR for 20 minutes. Five trials were carried out in each setting. Statistical analysis was carried out with SPSS 27.0. P < .05 was considered significant. Results: Positional shift after 20 minutes of CPR was as follows: tape fixation, 7.2 ± 0.2 mm; band fixation, no change, indicating a significant difference between the two groups (p=.003). The mean ventilation volume was tape fixation, 482.63 ± 30.84 mL; band fixation, 544.96 ± 22.98 mL, showing a significant difference (p=.002). Conclusion: When using the I-gel during pre-hospital CPR, using a band-type fixing device with elasticity rather than fixing the tape provides stable and appropriate ventilation by maintaining the fixed position.
