OBJECTIVES: Radiofrequency(RF) ablation is an effective and low risk curative treatment for supraventricular arrhythmias. Catheter ablation produced cardiac lesions primarily through formation of coagulation necrosis. We evaluated the degree of myocardial injury after RF catheter ablation by means of serial measurement of myocardial enzyme. METHODS: Fifty-one patients with symptomatic supraventricular tachycardia were included. There were 32 men and 19 women(mean age. 39.5+/-15.4 years)All patients underwent electrophysiologic study to detect accessary pathway and ablation with radiofreguency current. A mean of 18.3+/-14.2 radiofrequency pulses were delivered. The pulses were at a power of 50 to 60 Volts for a duration of 20 to 30 seconds. Unipolar method and a 6F or 7F catheter with a 4 mm tip electrode was used. LDH, CPK and Ck-MB as a kind of cardiac enzyme were measured before and after ablation. RESULTS: 1) The concentration of LDH and CPK were elecated at 8 hours and 16 hours after ablation (p<0.05). 2) The concentration of CK-MB was elevated at 8 hours, 16 hours, 24 hours and 72 hours after ablation(p<0.05). 3) There was no correlation between the number of applications and amounts of radiofrequency current and rise in LDH, CPK, CK-MB concentration. CONCLUSION: The concentration of LDH, CPK and CK-MB were elevated after ablation but they were within normal limits. RF catheter ablation produced myocardial damage inevitably but were within normal limits. RF catheter ablation produced myocardial damage inevitably but minimally, then RF ablation is an effective and safe therapeutic modality for patients with symptomatic tachyarrhythmias.

BACKGROUND AND OBJECTIVES: In acute myocardial ischemia, the conduction velocity of action potential is decreased by several electrophysiological and physical factors. The ventricular activation time(VAT) is a time duration of electrical impulse propagating from endocardium to epicardium. The goal of this study is to determine whether the reduction in conduction velocity in acute myocardial ischemia can lead a change in VAT. MATERIALS AND METHOD: Thirty patient, 18 males and 12 females, who had received percutaneous balloon coronary angioplasty(PTCA) were enrolled. The mean age was 59 years old. A twelve lead surface electrocardiogram(ECG) were obtained before, during, 1 minute, 5 minutes, and 10 minutes after the PTCA as digitized data by using Cardiolab EP 4.1 program. The magnitude of the QRS wave was amplified 3 to 4 folds and the speed was increased to 200mm/sec in order to get the VAT easily and accurately. The data was the mean of three consecutive VATs. The number of vessel treated with PTCA included left anterior descending artery(12), left circumflex artery(9), and right coronary artery(9). Among twelve chronic stable angina, sixteen unstable angina, and two acute myocardial infarction patients, twenty six had single and four had two vessel diseases. RESULTS: The significant increase in VAT during PTCA compared to that before PTCA was observed in eight of 12 leads. In addition, the significant decrease in VAT of 1, 5, and 10 minutes after PTCA compared to that during PTCA were noted. Furthermore, 10 minutes after PTCA, VAT decreased significantly compared to that before PTCA. The leads did not show a significant change of VAT depending on target vessels. The ECG of 16 patients showed changes of the ST segment during PTCA. The changes of VAT were not related to the ST segment change. CONCLUSION: The conduction delay from endocardium to epicardium in acute myocardial ischemia was presented as a prolongation of VAT in surface ECG. In addition, the conduction delay was recovered within 5 minutes after relief of ischemia. Therefore, the changes of VAT can possibly be used as one of the noninvasive parameters of myocardial ischemia.

Hydatidiform moles are generally separated into two clasifications. Complete hydatidiform moles are characterized by cystic swlling of all villi, often pronounced trophoblastic hyperplasia, lack of fetal parts, all 46 chromosomes of paternal origin(androgenesis), and a major risk for persistent trophoblastic tumor. Partial hydatidiform moles appear to be a milder version of complete moles with both normal and cystic villi, focal trophoblastic hyperplasia, a fetus or indications of previous fetal existence, 69 chromosomes with a maternal contribution, and a malignant potential less than described for complete moles. Hydatidiform mole with coexistent fetus is a very rare phenomenon, with an estimated incidence of 0.005 to 0.01 percent of all pregnancies. The rarity of live-born, surviving children may in part be due to termination of pregnancies, when molar parts are observed and without access to current advanced diagnostic procedures. Progress in techniques for first trimester prenatal diagnosis and improved surveillance of first trimester pregnancies through prenatal chromosomal analysis, ultrasound scan, maternal serum-hCG and serum- AFP screening has created complex situation, allowing confirmation of hydatidiform mole with coexisitng fetus. We recently experienced one case of unusual pregnancy with complete hydatidiform mole and coexisiting live fetus.

One family with asymmetric septal hypertrophy was reported. The propositus of this family was 31 years old man who was admitted because of transient syncope. His father and one brother were affected but asymptomatic. His sister was suddenly died at age 21 years. The interventricular septal thickness to left ventricular posterior wall thickness ratios were measured using M-mode echocard ogram. In the affected family, echocardiogram revealed asymmetric septal hypertrophy (1.5:1, 2:1, 1.9:1 respectively). In the propositus, cardiac catheterization and simultaneous biventricular cineangiography were performed. Pressure study revealed mild peak systolic pressure gradient within left ventricular apex and left ventricular outflow tract (4mm Hg respectively). Biventricular cineangiogram showed the septal width increased inferiorly, and left ventricular endocardial surface of the septum was straight, while the right ventricular border convex toward the right ventricle.

BACKGROUND: It was recently shown that human atherosclerotic plaque contains large numbers of T lymphocytes : this indicates that immune and inflammatory mechanism may be important factors in the pathogenesis of atherosclerosis. By measuring the soluble interleukin 2 receptor(sIL-2R) level we can evaluate the activation of T lymphocyte. The purpose of this study is to evaluate relationship between T cell activation and ischemic heart disease by measuring the soluble interleukin 2 receptor (sIL-2R) level in patient with ischemic heart disease. METHOD: Seventy-two patients(40 males and 32 female, mean age : 56.5+/-9.9 years) who were taken coronary angiography were included in this study. Among them, 49 patients showed abnormal coronary angiographic findings and 23 patients showed normal coronary angiographic findings. Ten mililiters of arterial blood was drawn at the time of coronary angiography. The blood was allowed to coagulate and then the serum was removed and tested in duplicate for soluble interleukin 2 receptor (sIL-2R) level by ELISA. RESULTS: 1) The soluble interleukin 2 receptor (sIL-2R) level was significantly different between abnormal coronary angiographic findings and normal coronary angiographic findings (P < 0.001). 2) According to clinical severity of ischemic heart disease (i.e. stable angina, unstable angina, acute myocardial infarction.), soluble interleukin 2 receptor (sIL-2R) level was not significantly different between single vessel disease group and multivessels disease groups (p > 0.05), but showed increasing tendency with clinical severity. 3) According to numbers of involved coronary vessels, soluble interleukin 2 receptor (sIL-2R) level was not significantly different between single vessel disease group and multivessels disease groups (p > 0.05). CONCLUSION: T lymphocyte activation, as reflected in elevated soluble interlekin 2 receptor (sIL-2R) level, is frequent in patient with ischemic heart disease. In the further we will investigate relationship between clinical diagnosis of ischemic heart disease of the numbers of involved coronary vessels and T cell activation.

Calcific tendinitis usually occurs in the supraspinatus tendon of the shoulder. Calcific tendinitis of the peroneus longus tendon has not been reported on the Korean journals. Differential diagnosis includes bipartitis os peroneum, os peroneum fracture and peroneal tendinitis. We report a rare case of calcific tendinitis of the peroneus longus tendon which responded well with the conservative treatment.

Although prenatal and neonatal intensive care in recent years improved survival of infants, the risk of cerebral palsy (CP) in infants with perinatal asphyxia persisted. Screening criteria for risk factors of cerebral palsy and delayed development (DD) in term infants with perinatal asphyxia are required so that early diagnosis and rehabilitation and physical therapy could decrease the neurologic complications and maximize quality of life. To identify the risk factors of CP and DD in infants with perinatal asphyxia, we undertook a case-control study of 25 infants with perinatal asphyxia (5 min Apgar score below 6). At one year follow-up, 12 infants developed CP and DD and 13 control infants showed normal development. Risk factors associated with an increased risk of CP and DD were the number of abortion (p=0. 031), history of neonatal seizure (p=0.021), hypoxic ischemic encephalopathy (p=0.046), and poor response to resuscitation immediately after birth (p=0.017). In term infants with perinatal asphyxia, the risk factors of CP and DD were increased number of abortion, history of neonatal seizure, and hypoxic ischemic encephalopathy and poor response to resuscutation. Thus infants with these risk factors should be carefully followed up after hospital discharge and further extensive and prospective study in term infants with perinatal asphyxia could elucidate possible mechanisms related to cerebral palsy and delayed development.
