Objective. The objective of this international comparative study was to investigate the clinical features and outcome of the treatment of infratemporal fossa abscess (IFA). Study design. This retrospective study was conducted at the Deptartment of Oral and Maxillofacial Surgery of Hallym University and "Iuliu Hatieganu" University of Medicine and Pharmacy. Ten-year records of patients were reviewed in Romania and six-year records were reviewed in Korea. The collected data was then analyzed. Results. A total of 36 cases were found to be IFA (12 males and 24 females: average age; $36.3{\pm}15.5$ yrs: 34 cases from Romania and 2 cases from Korea). The annual frequency of IFA in Romanian and Korean hospitals was 3.40 and 0.33 respectively (P<0.001). The etiology was septic anesthesia (33.3%), infection occurring after extraction (30.6%), periapical lesion (13.9%), impacted third molar (8.3%), post-extraction alveolitis (5.6%), and unknown (8.3%). A successful outcome was seen in 27 patients (75.0%) after initial treatment. The main complication after initial treatment was restricted movement of the mouth (9 cases). Conclusion. The etiology of IFA was various and minimal swelling hampered early diagnosis. To prevent IFA, preoperative painting with antiseptic agent must be stressed and proper drainage proved important to relieve pain and to prevent further complications.

Despite the necessity of surgical aortic valve replacement, many patients with symptomatic severe aortic stenosis (AS) cannot undergo surgery because of their severe comorbidities. In these high-risk patients, percutaneous transcatheter aortic valve implantation (TAVI) can be safely accomplished. However, no study has shown that TAVI can be performed for patients with severe AS accompanied by acute decompensated heart failure. In this case report, 1 patient presented a case of severe pulmonary hypertension with decompensated heart failure after diagnosis with severe AS, and was successfully treated via emergency TAVI. Without any invasive treatment, acute decompensated heart failure with severe pulmonary hypertension is common in patients with severe AS, and it can increase mortality rates. In conclusion, TAVI can be considered one of the treatment options for severe as presented as acute decompensated heart failure patients with pulmonary hypertension.

Dental stress is suggested as a main reason for behavioral problems in dentistry, especially in children. Heart rate is a useful measure of dental stress. The purpose of the present study is to examine the effect of dental stress on children receiving restorative treatment under local anesthesia by using recently introduced a wrist-watch type heart rate monitoring device. Eighteen children with no previous dental experience, who needed dental treatment involving local anesthesia, were included in this study. In each session, heart rate was recorded. The largest increase was observed during local anesthesia and the highest values were recorded during preparation. However, no significant relationship was found between the measurements(p > 0.05). Regarding the number of visits, heart rate on the second session is significantly higher than the first session and the third session(p < 0.05). There was no significant different correlation between the first session and third session(p > 0.05). Based on the present study, children who have no previous dental treatment appeared to be more stressed at the second session and need at least 3 sessions to feel less stressed during dental treatment including dental injection.

Robotically assisted mitral valve repair has proven its efficacy during the last decade. The most suitable approach for patients with difficult anatomies, such as morbid obesity, sternal deformities, cardiac rotation, or vascular anomalies, represents a current challenge in cardiac surgery. Herein, we present the case of a 71-year-old patient affected by severe degenerative mitral valve regurgitation with pectus excavatum and a right aortic arch with an anomalous course of the left subclavian artery who was successfully treated using a Da Vinci-assisted approach.

Recent advances in the surgical treatment of congenital disorders of the heart have necessitated an accurate preoperative diagnosis. Right heart catheterization has become widely accepted as a research tool and diagnostic test to detect the heart diseases, especially in the congenital heart anomalies. Right heart catheterizations were carried out in 50 cases of congenital heart diseases at Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital, during the period of June, 1975 through September 1978. In age distribution, 27cases were below 10 years of age, 18 cases between 11 and 20, and 5 cases above 20 male to female ratio was 2.8:1. The distribution of congenital heart diseases was VSD [42%], TOF [36%], PDA [10%], ASD [8%], and PS[4%]. Of these, 44 cases [88%], were compatible with the clinical impressions that were made preliminarily before cardiac catheterization, and all the cases except 1 case of VSD was correlated well with the postoperative diagnosis. The right heart catheterization is considered to be reliable and accurate toll in the preoperative diagnosis of congenital heart diseases. These procedures caused complications such as left side hemiplegia [lcase], occlusion of the femoral artery [lcase], and transient ventricular tachycardia [1case], and so the complication rate of right heart catheterization was 6% [3 cases]. None of patients who have undergone right heart catheterization was died.

In radiation treatment, it is unavoidable to block the influence of scattered ray on a skin and prevent internal normal organs from being exposed to radiation. It is fair to say that radiation therapy aims to reduce an absorbed dose of normal tissues. In particular, in radiation therapy of left-sided breast cancer, the internal neighboring organs are normal breast tissues, the heart, and the lung. The side effects on the heart include cardioplegy and myocardial infarction. This study tried to observe changes in the volume and dose of the heart in general radiation therapy plan and respiratory control based radiation therapy plan for patients with left-sided breast cancer, and to find the heart's volume and dose generated by respiration. According to the 4D computer tomography (CT), a volume of the heart had $12.8{\pm}8.7cc$ on average, and its dose had $17.3{\pm}12.1cGy$ on average. The differences in the volume and dose may cause side effects in radiation treatment. Therefore, it is necessary to apply respiratory control technique to establish the radiation treatment plan based on an accurate position of the heart.

Background: The aim of this study was to evaluate the short-term and long-term results of surgical treatment for native valve endocarditis (NVE) and to investigate the risk factors associated with mortality. Methods: Data including patients' characteristics, operative findings, postoperative results, and survival indices were retrospectively obtained from Hallym University Sacred Heart Hospital. Results: A total of 29 patients underwent surgery for NVE (affecting the mitral valve in 20 patients and the aortic valve in 9) between 2003 and 2017. During the follow-up period (median, 46.9 months; interquartile range, 19.1-107.0 months), the 5-year survival rate was 77.2%. In logistic regression analysis, body mass index (p=0.031; odds ratio [OR], 0.574; 95% confidence interval [CI], 0.346-0.951), end-stage renal disease (ESRD) (p=0.026; OR, 24.0; 95% CI, 1.459-394.8), and urgent surgery (p=0.010; OR, 34.5; 95% CI, 2.353-505.7) were significantly associated with in-hospital mortality. Based on Cox proportional hazard regression analysis, the statistically significant predictors of long-term outcomes were hypertension, ESRD, and urgent surgery. Conclusion: Surgical treatment for NVE is associated with considerable mortality. The in-hospital mortality and 5-year survival rates of this study were 13.8% and 77.2%, respectively. Underlying conditions, including hypertension and ESRD, and urgent surgery were independent risk factors for unfavorable outcomes.

From April, 1981, through March, 1989, 30 patients had received valve replacements and 1 patient had received foreign body removal for infective endocarditis at Seoul National University Hospital. There were 22 male and 9 female patients, ranged in age from 22 to 59 [mean 34.9] years. Twenty-three had native valve endocarditis, 7 had prosthetic valve endocarditis and 1 had infected transvenous permanent pacemaker electrode in right heart. Twenty-four required operation during active phase of disease and 7 during inactive phase. The infecting organism was Streptococcus in 10 patients, Staphylococcus in 5 patients, both Staphylococcus and Streptococcus in 1 patient, E. coli in 2 patients, and Candida in 1 patient. Indications for Surgery were congestive heart failure in 20, systemic emboli in 5, combination of both in 3, congestive heart failure with uncontrolled sepsis in 2, and complete heart block in 1 patient. Hospital mortality was 9.7% [3/31], and all were the patients who received emergency operation. There were 2 late mortality [7.7 %] due to acute myocardial infarction and recurrent endocarditis. This report suggests that the surgical treatment can be achieved with acceptable low mortality and morbidity in medically intractable congestive heart failure, emboli and sepsis.
