To determine factors involved in left ventricular aneurysm formation after transmural anterior myocardial infarction, 74 patients with a first myocardial infarction who underwent cardiac catheterization within 6 weeks of infarction were evaluated.Patients were divided into four groups depending on the status of the left anterioe descending artery(LAD) and the presence Group I(n=15);aneurysm with occluded LAD, Group II(n=16);no aneusrysm and occluded LAD, Group III(n=18);aneusrysm and patent LAD, and Group IV(n=25);no aneusrsm with patent LAD. Neither age, sex nor risk factors for coronary disease correlated with aneusrysm formation,but the duration of chest pain in patients with previous angina was significantly longer in group II(no aneusrysm with occluded LAD) compared with other groups(P<0.01). Single vessel disease was more commom in Group I and III(aneusrysm) compared with II and IV(no aneusrysm)(P<0.06). Collateral blood supply was more frequently observed in Group I and II(occluded LAD) compared with Group III and IV(patent LAD)(P<0.01) and was slightly less in Group I(aneusrysm) compared with Group II(no aneusrym)(P<0.07). Delta area decreasing rate of the left ventricle was significantly lower in Group I and III(aneusrysm)compared with Group II and IV(no aneusrysm)(P<0.01). Single vessel disease in assocition with poor collateral circulation tends to be a determinant of left ventricular aneusrysm formation after anterior myocardial infarction.

From May, 1978 through Oct., 1979 the effect of Coenzyme Q10 was evaluated on 10 patients with chronic heart failure. The subjects selected for this study consisted of 7 patients with cardiomyopathy and 3 patients with valvular heart disease admitted to Severance Hospital, Yonsei University College of Medicine, All these patients had symptoms and signs of congestive heart failure which was stable for at least one month before starting Coenzyme Q10. Coenzyme Q10 was administered 30mg daily for eight weeks, one hour before meal and in combination with digitalis and/or diuretics. The drug effects were determined by measuring the cardio-thoracic ratio by chest X-ray, the sum of 'S' wave in V1 and 'R' wave in V5 in electrocardiogram, and PEP/LVET (pre-ejection period/left ventricular ejection time) by simultaneous tracings of carotid pulse and phonocardiogram every two weeks during medication. The cardio-thoracic ratio was improved in 4 of 10 cases, the sum of RV+SV5 was decreased in all 5 cases who showed voltages above 40mm before medication, and PEP/LVET ratio was decresed in 4 of 10 cases. The difference of average values before and after medication were not statistically significant(p<0.05) in all 3 parameters when examined by t-test. During treatment, there was improvement, if any, from two weeks after medication and no significant side effects were noted throughout the study period.

Ganglia of the cruciate ligament are quite rare. About 60 cases were reported previously in the world and 6 cases were reported at two articles in korea. It's symptoms may be similar to those of internal derangement of knee, especially meniscal lesion. We report a case of isolated ganglion of posterior cruciate ligament with brief of literatures.

To evaluate the change in valvular morphology and occurence and severity of mitral regurgitation produced by PMV, 45 patients(33 women and 12 men,mean age 38+/-10 years) were studied using two-dimensional(2-D) and Doppler echocaediography before and 1-2 days after this procedure. Mitral valve area after PMV increased in all patients, from 0.9+/-0.2 to 1.8+/-0.4cm2(P<0.0001). In valve area estimation, the correlation between Gorlin`s method and 2-Dechocardiography was better(r=0.61, p<0.0001) than that between Gorlin`s method and Doppler pressure halftime(r=0.38, P<0.01) before valvuloplasty, but after the procedure Gorlin`s and 2-D image valve area correlated less well(r=0.33, P<0.05) than Gorlin`s-Doppler pressure halftime correlation(r=0.46, P<0.002). Before PMV, 37 patients had no mitral regurgutation, 7 had grade 1 and 1 had grade 2 mitral regurgutation. After PMV, new mitral regurgutation occurred in 14 patients, increased in severity in 5 patients and so mitral regurgutation newly developed or increased in severity in 19(42%) patients. There were no differences between the patients with and those without an increase in mitral regurgutation after PMV, in age, sex, caediac rhythm, initial mitral valve area, increase in mitral valve area and fluoroscopic calcification. However, morphologic characteristics especially mobility(P<0.01) and thickening(P<0.05) of mitral leaflets were better pressured, and EBDA/BSA(effective balloon dilating area/body surface area) was significantly smaller(P<0.02) in patients without an increase in mitral regurgutation. Thus, an increase in mitral regurgutation after PMV might be related to the features of valve morphology especially and thickand EBDA/BSA.

Recent studies showed effective early recannalization of infarct-related artery achieved by intravanous urokinase, but dosage of urokinase is still arbitary. Thirty-five patients with acute trasmural myocardial infarction were treated with intraveous urokinase from April 1984 to October 1988. The incidence of coronary thrombolysis, left ventricula function and effect on fibrinolytic system were investigated. Inital 18 patients recieved 0.5 to 2.0 million unitis of urokinase and remaining 17 patients received 3 million units of urokinase intravenously for 1 hour. Thirteen of 17 patients(76.4%) with 3 million units but only four of 18 patients(22.2%) with 0.5 to 2.0 million units showed patent infarct-related coronary artery. Left ventricular function was significantly better in patients with patent infarct-related coronary artery, and the difference was marked in anterior myocardial infarction. There were three local bleeding at puncture site in 3 million units group, one of which required transfusion. Thus, intravenous infusion of 3 million units of urokinase provide rapid reperfusion of infarct-related coronary arterty and myocardial salvage is more lkiely to occur.

OBJECTIVES: We propose here a classification system for external auditory canal cholesteatoma (EACC). We classified the EACC by the computed tomography findings and clinical findings of the patients, and we evaluated the EACC characteristics by the proposed staging system. METHODS: Stage classification was done according to the results of temporal bone computed tomography and the clinical findings of the patients. Stage I indicates that the EACC lesion is limited to the external auditory canal. Stage II indicates that the EACC lesion invades the tympanic membrane and middle ear. Stage III indicates that the EACC lesion creates a defect of the external auditory canal and it involves the air cells in the mastoid bone. Stage IV indicates that the EACC lesion is beyond the temporal bone. Between 1996 and 2006, 29 patients with EACC and who underwent surgery were prospectively collected. This study was comprised of 16 males and 13 females with a mean age of 22.8+/-15.0 yr. We reviewed the characteristics and results of surgery by our proposed staging system. RESULTS: A total of 29 patients who underwent operation due to EACC were classified by this system, and the number of stage I, II, III, and IV cases was 14, 3, 10, and 2, respectively. Symptoms such as otorrhea, hearing impairment and otalgia occurred in 12, 17, and 17 cases, respectively. The most common wall invaded by EACC was the inferior wall. The number of cases that had a spontaneous, congenital, post-traumatic, post-inflammatory or tumorous origin was 14, 9, 2, 2, and 1, respectively. Cholesteatoma recurred in 2 patients after surgery. Both cases were stage 1 and both were caused by congenital disease. There were 3 cases with meatal stenosis after surgery, and their primary disease was congenital. CONCLUSION: This proposed staging is simple and easily applicable for use when deciding the treatment plan for patients with EACC.

PURPOSE: To evaluate the value and the radiologic findings of CT discography in the diagnosis of the far lateral disk herniation. MATERIALS AND METHODS: We retrospectively reviewed 7 cases of surgically proven far lateral lumbar disc herniation. CT discography was performed for all cases. Four cases underwent conventional CT and three cases MRI as a primary diagnostic imaging method. Far lateral diac herniation was divided into 3 groups by location;Intraforaminal herniation, extraforaminal herniation, and mixed type. We analyzed the findings of CT discography including location and extent of far lateral disc herniation. RESULTS: In all 7 cases, CT discography clearly demonstrated the filling of contrast media in laterally-protruded disc material. Intraforaminal and extraforminal types were seen in 2 cases each, and mixed type in 3 cases. Subligamentous herniated nucleus pulposus was present in 6 cases and extruded disc in 1 case. Far lateral disc herniation was located at L4-5 in 5 cases and L5-S1 in 2 cases. CONCLUSION: CT discography can help establishing accurate preoperative diagnosis for far lateral disc herniation.
