The index on myocardial contractility of pure mitral regurgitation(MR) after mitral valve replacement is believed to be useful in determining proper operation time before irreversible myocardial damage by volume overload. Thus the authors examined pre and post-operative echocardiographic results of 20 cases of pure MR patients who had been admitted to Pusan National University hospital and compared the usefulness of each index. Pre and post-operative echocardiographic results were as follows respectively ; 1) Left ventricular internal dimension in diastole(LVIDd) were 6.49+/-0.19cm and 5.51+/-0.17cm. 2) Left ventricular internal dimension in systole(LVIDs) were 4.26+/-0.12 and 3.79+/-0.18cm. 3) Ejection fraction were 71.28+/-1.57% and 59.24+/-3.05%. 4) Fractional shortening(FS) were 34.09+/-1.18% and 27.21+/-1.84%. 5) Mean Vcf were 1.53+/-0.08cm/sec and 1.18+/-0.09cm/sec. 6) Left ventricular end-diastolic volume index(EDVI) were 196.35+/-18.33cc/m2 and 98.46+/-9.96cc/m2. 7) Left ventricular end-systolic volume index(ESVI) were 55.28+/-5.12cc/m2 and 41.88+/-6.07cc/m2. 8) Left ventricular end-systolic wall stress/ESVI(ESS/ESVI) were 2.3+/-0.21 and 3.91+/-0.83. ESS/ESVI showed significantly(p<0.05) elevated postoperative change, LVIDd, LVIDs, EF, FS, EDVI, ESVI revealed significantly(p<0.05) reduced postoperative change whereas Mean Vcf had no postoperative change. After examining correlation between preoperative and postoperative results of each index, it is believed that LVIDd, LVIDs, and ESS/ESVI were useful prognostic indices but were unrelated to postoperative ejection phase indices such as EF, FS, and MEan Vcf. Especially in case of LVIDd>6cm, LVIDs>4cm, and ESS/ESVI<2, the prognosis was poor due to myocardial damage by mitral regurgitation.

The purpose of this study is to evaluate the ventricular conduction abnormalities, especially RBBB, observed electrocardiographically after surgical closure of VSD. The present study population consists of 92 patients with VSD who were surgically corrected at the Hanyang University Hospital during 6 years period from Jan. 1985 to Dec. 1990. We reviewed their clinical records including surgical notes and EKG findings before and after operations. The results of the study were as follows: 1) Male to female ratio was 1.1:1 (48:44) 2) Out of a total of 92 cases of VSD, 65cases(70.7%)were perimembranous type and 27 cases (29.3%)were subarterial type. 3) The normal preoperative EKG findings were seen in 22 patients, LVH in 21 patients, BUH in 47patients, and RVH in 3 patiens. 4) A transatrial approach was performed in 55 cases, right ventriculotomy with or without resection of muscles in right ventricle in 13 cases, and pulmonary arteriotomy alone in 24 cases. 5) The right bundle branch block after operation developed in 33 patients out of the 65 patinets with perimembranous defect and 5 patients out of the 27 patients with subarterial defects. Postoperative RBBB developed more frequently in perimembranous defect than in subarterial defect. 6) Postoperative RBBB occured in 31.8% of the patients with normal preoperative EKG findings, 23.8% with preoperative LVH, 52.1% with BVH and 66.7% with RVH. Postoperative RBBB was more frequently observed in the patients group with preoperative BVH or RVH than the patients with normal or LVH. 7) Postoperative RBBB was observed in 84.6% after right wentriculotomy, in 43.6% after right atriotomy and in 12.5% with pulmonary arteriotomy alone.

OBJECTIVES: From February 1995 to April 1998, those patients who had visited for evaluation of infertility, shown abnormal endometrial pattern on hysterosalpingography underwent resectoscopic operation. We evaluated about its therapeutic effect, recurrence rate of uterine adhesion and effectiveness of its assisted method. METHOD: We have reviewed 45 cases of intrauterine adhesion, classified as a central type, marginal type and multiple type. We used 26F resectoscope made in Storz for operation and inserted Lippes loop or pediatric foley catheter for prevention of readhesion. For promoting reepithelialization, conjugated estrogens(premarin) 5mg daily for 30 - 50 days were given and then 10mg of medroxyprogesterone acetate(provera) were added daily for the last 10 days. We evaluated the uterine cavity condition preoperatively and postoperatively by using hysterosalpingography. RESULT: In 45 cases, 41 cases were followed up postoperatively. 21 cases were markedly improved, 12 cases were improved and 8 cases were not improved or recurred on hysterosalpingography. In 41 cases, for prevention of readhesion 20 cases were used pediatric foley catheter and 5 cases(25%) were recurred. 21 cases were used Lippes loop and 3 cases(14%) were recurred. Pregnancy outcome was as follows;15 cases were pregnant and 10 cases delivered a viable infant, 3 cases aborted spontaneously, 1 case was ectopic pregnancy and laparoscopic salpingectomy was done, 1 case was ongoing pregnancy. CONCLUSION: This report suggests that resectoscopic operation is very effective in the treatment of intrauterine adhesion(therapeutic rate of 81%) and that the use of Lippes loop seems like to have the less recurrence rate than the use of pediatric foley catheter in prevention of postoperative readhesion, but more experience and further follow-up are necessary to obtain more detailed conclusions.

PURPOSE: In spite of preventive measures and excellent prognosis with immediate treatments, drowning and drowning- related injuries remain as one of the leading causes of accidental death in Korea. However, abundant statistical data for drowning has yet to be collected. Thus, this study aimed to describe the epidemiologic characteristics of drowning in terms of demographic characteristics, geopolitical factors and socio-economic status. METHODS: This study was conducted with drowning patients who either visited hospitals or died between January 2001 and December 2003. Of these patients, we enrolled individuals registered for such coverages as automobile insurance, national health service and work injury insurance and we reviewed death records reported to the Korea National Statistical office. NISS (New Injury Severity Scale) and EMR-ISS (the Excessive Mortality Ratio -adjusted Injury Severity Score) values were calculated for each patients and the results were classified 4-into four different severity groups. After analysis, we drew conclusions in terms of year, gender, age, region, insurance type, daily rate of incidences and severity. RESULTS: The incidences of drowning-related injury were 2,486 in 2001, 2,364 in 2002, and 2,595 in 2003 (average of 2,482). The average annual death were 1,954. Victims were more likely to be male and especially high incidence rates were found for two groups: (1) Children aged 5-9 years, (2) Adults aged 40 and older. Seoul and Gyeonggi had the largest total numbers of injury cases, while JeJu had the highest per capita incidence rate (106 per 1,000,000 population). The seasonal distribution of incidence rates showed that predictably, incidents were most frequent between the beginning of July and September. CONCLUSION: The average number of incidents was 55.73 per 1,000,000 population, which constitutes approximately 0.02% of all injuries. Based on this data, we recommand continuing studies and further evaluations in order to develop specific measures to combat drowning.

Objective: To understand the anatomic characteristics of the aortic arch (AA) and its major branches to build a foundation toward performing endovascular surgery safely. Methods: A total of 25 formalin fixed Korean adult cadavers were used. The authors investigated : anatomical variations of the AA and its major branches; curvature of the AA; distance from the mid-vertebrae line to the origin of the major branches; distances from the origin of the major branches of AA to the origin of its distal branches; and the angle of the three major branches, the brachiocephalic trunk (BCT), the left common carotid artery (LCCA) and the left subclavian artery (LSCA) arising from AA. Results: The three major branches directly originated from AA in 21 (84%) of the cadavers. In two (8%) of remaining four cadavers, orifice of LCCA was slightly above the stem of BCT. In remaining two (8%) cadavers, the left vertebral artery (LVA) was directly originated from AA. Average angle of AA curvature to the coronal plane was 62.2 degrees. BCT originated 0.92 mm on the right of the mid-vertebrae line. LCCA and LSCA originated from 12.3 mm and 22.8 mm on the left of the mid-vertebrae line. Mean distance from the origin of the BCT to the origin of the RCCA was 32.5 mm. Mean distance from the origin of the LSCA to the origin of the LVA was 33.8 mm. Average angles at which the major branches arise from the AA were 65.3, 46.9 and 63.8 degrees. Conclusion: This study may provides a basic anatomical information to catheterize AA and its branches for safely performing endovascular surgery.
