Coenzyme Q is concentrated in Golgi apparatus membranes and mitochondria, but not in other membranes. Although it is difficult to prove the metabolic action of coenzyme Q administered exogenously in clinical cases, the effect of this substance can be evaluated by criteria based on clinical findings. In an attempt to evaluate the effect of coenzyme Q for the treatment of 67 patients(male 26 cases, female 41 cases) of congestive heart failure, we administered Coenzyme Q1030mg daily for 4 to 8 weeks. Most of them were valvular heart disease(74.6%) and hypertension (14.9%). Clinical effects were evaluated at least 4 weeks later by the criteria using a scoring method of severity of congestive heart failure which was devised by Ishiyama, etc. In summary, a definite effect was found in 13 cases(19%) and a mild effect was observed in 46 cases(69%). During treatment there were no significant side effects, and also no significant changes in heart rate and blood pressure.

Imipramine(Tofranil(R)) is one of the tricyclic antidepressants commonly used in depressive symptoms or enuresis. An accidental or nonaccidental poisoning of imipramine is common today. A 16 years old girl was admitted to Seoul National university Hospital because of unocnsciousness and frequent attacks of seizure after the impulsive ingestion of 1.4gm of imipramine. She showed variable arrhythmias such as complete RBBB, secod degree AV block and ventricular tachycardia and recovered from poisoning without residual myocardial damage. We present a case of imipramine poisoning with cardiac arrhythmias with review of literatures.

PURPOSE: We studied to evaluate the safety and effectiveness of the domestic SDS-3000(R) extracorporeal shock wave lithotriptor (SWL). MATERIALS AND METHODS: Between October 1995 and April 2000, 440 patients, 16 to 79 years old, were treated with the domestic SDS-3000(R) lithotriptor using C-arm fluoroscopy without regional or general anesthesia. Distribution of stones, location and size of stones, session, success rate, causes of failure and complications of SWL were retrospectively reviewed. RESULTS: Of 440 patients, renal stones were 133 (30.2%) and ureteral stones 307 (69.8%). The overall success rate (stone free rate) of SDS-3000(R) lithotriptor in 440 patients was 89.8% (81.4%) with 94.9% (91.0%) in 5-9mm, 87.2% (75.8%) in 10-19mm, 66.7% (42.8%) in 20-29mm and 57.1% (35.7%) over 30mm of stone size. The success rate was 94.9% for stones between 5-9mm in diameters and 82.6% for stones more than 10mm (p<0.05). As compaired with success rate for stones less then 20mm, stones more then 20mm had significently higher success rate (92.1% Vs 62.8%) (p<0.05). Ureter stones were more successfully treated than renal stones (93.2% Vs 82.0%) (p<0.05). Main complications of SWL were renal colic in 10.0%, steinstrasse in 4.3%, transient gross hematuria in 1.8% and fever in 1.1%. All of complications were controlled with conservative treatment. CONCLUSIONS: The domestic SDS-3000(R) lithotriptor monotherapy is considered to be a safe and efficient outpatient procedure for the initial treatment of urinary stones.

Prosthetic valve endocarditis(PVE) is not infrequent and one of the serious complications of cardiac valve replacement despite advances in antimicrobial therapy, diagnostic techniquens and surgical procedures. Although the incidence of PVE may be declining, the absolute number of cases of this infection is increasing. In patients with a prosthetic valve, fever, a regurgitant heart murmur, peripheral manifestations of infective endocarditis and postitive blood cultures, the diagnosis of PVE is evident. We have reviewed our experience with 13 patients with PVE from October 1976 through August 1983. During this period valve replacements were performed in 686 patients, with an infection rate of 1.9%. PVE currently accounts for approximately 14% of the total number of cases of infective endocarditis seen at Seoul national University Hospital. PVE occurred more often after multiple valve replacement than after replacement of single valve alone. Blood cultures were positive in 69% cases of PVE. Systemic emboli could be seen in 54% of patients with PVE and overall mortality was about 23%.

41 patients with hyperlipidemia(Serum cholesterol > or =260mg% or triglyceride> or =200mg%) were treated for 12 weeks each with either Bezafibrate(200mg t.i.d.)(n=23) or placebo(n=18) in a randomized trial. Compared with placebo, Bezafibrate was more effective in lowing total cholesterol(287+/-63 to 244+/-32 mg%, P<0.01), LDL-cholesterol(183+/-39 to 153 +/-25mg%, P<0.01) and the LDL/HDL ratio(4.7+/-2.9 to 3.4+/-1.3, P<0.05). There was also a marked reduction in serum triglyceride(307+/-295 to 218+/-167mg%, P<0.05) as well as a significant increase in HDL-cholesterol(43+/-12 to 48+/-12mg%, P<0.05). Compliance or tolerance to both Bezafibrate and placebo was good. No significant side effects except one case, who complained of mild indigestion, were observed. Therefore, Bezafibrate seemed to be effective in lowing serum total cholesterol, LDL-cholestrol, triglyceride and in increasing in HDL-cholesterol without significant side effect.

From May, 1975 to August, 1986, we experienced 21 patients with ruptured aneurysm of the sinus of Valsalva. 1) Their ages ranged from 15 to 52 years with a mean age of 26.7 years, and 14 patients were male and 7 patients were female. Among 18 cases of which aneurysms occurred on the right sinus of Valsalva, 15 cases (83%) ruptured into the right ventricle, 1 case (6%) ruptured into the right atrium and 2 cases (11%) ruptured into the pulmonary artery. All 3 cases of which aneurysms occurred on the noncoronary sinus ruptured into the right atrium. 2) Clinical symptoms consisted of dyspnea (95%), palpitation (81%), chest pain (43%), orthopnea (33%), cough (14%), hemoptysis (5%), oliguria (5%), and fever (5%). In all patients continuous heart murmur was audible. Hepatomegaly (48%), pulmonary basal rale (14%), and pretibial pitting edema (19%) were also observed. 3) In all patients diagnosis was made with cardiac catheterization and angiography, and confirmed by operation excetpt one case. 4) Among 20 patients who had been performed corrective surgery, ventricular septal defect was observed in 16 patients (85%), aortic insufficiency in 5 patients (25%), pulmonary infundibular stenosis in 1 patient (5%), patent foramen ovale in 1 patient (5%), and tricuspid insufficiency in 1 patient (5%). Ventricular septal defect was observed in all 16 patients whose aneurysms of the right coronary sinus of Valsalva ruptured into the right ventricle and the pulmonary artery. 5) All patients survived operation, and no postoperative complication was found except 1 patient to whom reoperation was performed because of postoperative aortic insufficiency and detachment of the patch closure for ventricular septal defect. There was symptomatic improvement in all patients.

An 8-year-old male was admitted because of dysphagia and substernal pain suffered while eating followed by postprandial vomiting for 2 years. He was always hungry due to postprandial vomiting and willing to eat again just after vomiting. After this meals, he used to jump up and down to shake off the substernal discomfort. A narrowing of the gastroesophageal junction was noted by esophagogram. Manometry revealed high Lower esophageal sphincter (LES) pressure (51.6mmHg), incomplete LES relaxation during swallowing, loss of esophageal peristalsis and a positive pressure of the esophageal body compared to intragastric pressure. After the 1st balloon dilatation, symptoms were much improved even though LES pressure still remained high (37.2mmHg). About 2 months after the 1st balloon dilatation, symptoms relapsed and we managed him with a 2nd balloon dilatation. Symptoms were more improved than after the 1st dilatation and LES pressure normalized as well. Since the 2nd dilatation, symptoms have not recurred for 3 years. We present an 8-year-old boy with achalasia successfully managed by the use balloon dilatation.

An anomalous left coronary artery from the pulmonary artery(Bland-White-Garland syndrome) is a rare congenital malformation and sometimes fatal. It is caused by an abberant endothelial budding from or an anomalous division of the truncus arteriosus. Echocardiography (transthoracic and transesophageal) and angiographical imaging are essential for the diagnosis of this anomaly. Corrective Surgery is recommended due to its fatal natural course. A case was diagnosed in a 45-year-old man who presented with intermittent palpitation. This patient was successfully treated with closure of anomalous left coronary artery orifice combined with right saphenous vein graft anastomosis.

The P wave during orthodromic atrioventricular reentry tachycardial were analysed in 19 patients to evaluate the usefulness in identifying the location of accessory pathways. The results were as follows; 1) Definitely inverted and upright P waves in lead I represented the left-sided and right-sided pathways respectively, but the converse is not necessarily true. 2) Dome and Dart appearance in lead VI(4 cases), upright P wave in inferior leads(3 cases), and negative P wave in aVL(3 cases) suggested the left-sided pathway and deeply inverted P waves in inferior leads suggested the posteroseptal or right-sided one. 3) In 17 cases(79%), inverted P wave appeared on more than one lead among the inferior leads, which were helpful to identify the position on P wave and mechanism of supraventricular tachycardia. Although the number of cases especially with right-sided pathway was small to conclude, P wave was useful for determining the location of accessory pathway noninvasively.

Seventeen cases of apical hypertrophic cardiomyopthy were reviewed to clarify whether there is any racial difference in phenotypic expression of apical hypertrophic cardiomopathy and to study whether there is any clinical or morphological difference between apical hypertrophic cardiomyopathy of Japanese type (J-APH) and apical hypertrophic cardiomyophthy of non-Japanese type (NJ-APH). The diagnosis was made by cardiac catheterization, left ventriculography and echocardiography. Seventeen patients were divided into 9 (53%) patients with J-APH and 8 (47%) patients with NJ-APH. Mean ages of patients with J-APH and NJ-APH were 55 years and 57 years, respectively. The most common clinical symptoms were chest pain(100%), dyspnea(59%) and palpitation(35%). Mean values of S1+R5 and T wave depth were 58+/-16mm and 16+/-6mm in J-APH and 42+/-11mm and 7+/-3mm in NJ-APH(p<0.05, respectively). Seven patients experienced transient or permanent atrial fibrillation without significant symptoms. Seven patients showed progression or regression of T wave depth greater than 5mm during the period of follow-ups. On echocardiography IVS/LVPW thickness(mm) at the base were 11+/-2/10+/-2 in J-APH and 17+/-7/11+/-2 in NJ-APH, and IVS/LVPW thickness(mm) at the apex were 25+/-7/24+/-5 in J-APH and 26+/-3/26+/-2 in NJ-APH. Three patients with NJ-APH showed asymmetrical septal hypertrophy, cardiac catheterization disclosed elevated left ventricular end diastolic pressure in 11 out of 19 patients. Dye entrapment at the apex during systole was noted in 5 out of 18 patients. In conclusion, our study showed high prevalence rate expression of J-APH in contrast to the Western countries, there may be racial difference in phenotype of apical hypertrophic cardiomyopathy. Considering progression or regression of T-wave depth, NJ-APH may be a forme fruste or regressed form of J-APH.
