Coarctation of the aorta is an important congenital cardiovascular defect,. which occurs in a significant number of persons. The basic anatomic defect is a localized deformity of the media, manifested by two types of strictures in the aorta: "true" coarctation and tubular hypoplasia. The zone of coarctation is characteristically located distal to the origin of left subclavian artery at or just beyond the insertion of the ligamentum arteriosum. It shortens life if untreated, but it can be corrected to render the patient functionally normal. Here we have a 2-year operative experiences with 3 cases of the aortic coarctation, two of hypoplastic type and one of postductal type, at age of 17 to 19 year old Korean, operated in 1965 and l968 at the National Medical Center. The purposes of this report are to describe the immediate and late effect of surgery, histopathologic bases and the rarity of this lesions in Korea.

N/A Background: Since initial treatment for complete heart block with external transvenous pacemaker by Zoll in 1952, the frequency of the use for cardic pacing has increased considerably and the indications for long term pacing have greatly extended according to the development of smaller and multiprogrammable pacemakers. Complications related to cardic pacemaker have also been diversified. Method: To examine complications related to them, we studied 59 implantations of permanent pacemaker from January 1986 to October 1992 at National Medical Center. Results: 1n this study we experienced 16 cases (27.1%) of complications for cardiac pacing in 59 implantations of permenent pacemaker. They included two cases (12.5%) of pacing failure, two cases (12.5%) of undersensing of wide QRS wave, one ease (6.3%) of undersensing of APC, one case (6.3%) of dislodgement, three cases (18.8%) of oversensing, two cases (12.5%) of pacemaker induced CHF, three cases (18.8%) of competition and two cases (12.5%) of wound infection. Conclusion: With more frequent use of permanent pacemaker, it is thought that the development of ideal pacemaker is required.

N/A Objectives: The exercise test is commonly used in conjunction with baseline clinical information to estimate the likelihood that a patient has significant coronary diseases. The purpose of this study was to determine if patterns of ST depression or elevation during exercise testing provide reliable information about the location of an underlying coronary lesion. Methods: We reviewed 49patients out of 137patients who performed treadmill test and coronary angiography at National Medical Center from January, 1984 through August, 1993. All the patients underwent modified Bruce protocol treadmill exercise test and coronary angiography. Exercise ST changes were classified as depression or elevation by lead groups involved(V1-V3, V4-6, I AVL, II III AVF), Coronary angiography was done in several oblique projections and results were reviewed by at least two senior angiographers. Results: 1) There were significant stenosis in coronary angiography in 22cases(70.9%) among positive 31cases, 0cases(0%) among borderline positive 4cases, 5cases(10.2%) among negative 49cases. 11cases(47.8%) among nondiagnostic 23cases, and 3cases(25%) among pseudonormalization 12cases in exercise treadmill tests. 2) The sensitivity of treadmill exercise electrocardiography was 61.2%, and specificity was 81.8%. The sensitivity of each coronary artery diseases was 6l.7% in Left anterior descending artery disease, 66.6% in Right coronary artery disease, 38.5% in Left circumflex artery disease, 100% in 2-vessel disease, and 100% in 3-vessel disease. 3) ST depression was not useful in predicting the site of coronary artery narrowing. In contrast, ST elevation was correlated with coronary artery disease. 4) ST depression was most often seen in leads V4-V6 and leads II III AVF without correlation between the diseased coronary artery and the leads in which ST depression occurred. Conclusion: The exercise treadmill induced depression of the ST segment is an significant sign for predicting the presence of coronary artery disease and for the decision to perform coronary angiography. But, site of ST depression during exercise is not a good predictor of anatomic site of coronary artery disease. The other noninvasive test and coronary angiography may be necessary to nondiagnostic group which revealed insufficient exercise load or target heart rate during exercise test because the presence of coronary artery disease can't be ruled out.
