This report is based on analysis of admissions to the department of pediatric at the Wonju Christian Hospital during the 3 3/4-year period from January 1989 to September 1993 with an Isolated ostium secundum ASD. Several methods of assessment of ASD size, namely, echographic, pulmonary-to-systemic flow ratio(Qp:Qs), and angiographic measures, were undertaken in a group of 37 patients, who were being evaluated for transcatheter closure of ASD; the results were compared with the operation diameter. The result of study was as follows : 1) The (Qp:Qs) ratio have no significant(p>0.01) correlation with the operation diameter(r= 0.342) 2) The angiographic size have a significant(p<0.01) correlation with the operation diameter (r=0.842) 3) The echo diameter has the best correlation with the operation diameter(r=0.935; p<0.01) The operation diameter can be estimated by the equation: 1.05 x echo diameter in millimeters+0.93mm. It is concluded that operation diameter of ASD can be estimated accurately by two-dimensional subcostal echo measurements, which in turn could be used for selection of device size for occlusion of the ASD.

From January to December 1984, 191 patients with associated ventricular septal defect(VSD) were studied in the cardiac cathetherization laboratory. Among theses 191 cases, 58 cases(30.4%) of subpulmonic VSD were identified by angiocardiography. Among the 59 cases of subpulmonic VSD, 12 cases(20.6%) were complicated with aortic infficiency(AI). The relative frequency of subpulmonic VSD increased with the increase of age and the frequency of complication of AI with the subpulmonic VSD also increased with the increase of age. The amount of left to right shunt in the patients with subpulmonic VSD and AI was small and Qp/Qs ratio was less than 2.0 in all of the 12 cases. Among the 12 patients 4 cases had a pressure gradient greater than 20 mmHg across the infundibular region of the right ventricle.

Aortic dissection is clinically suspected from the typical symptoms and signs and may be confirmed by computed tomography or aortography. But atypical presentations can be seen in a minority of cases, such as SVC syndrome, right pulmonary artery stenosis etc. We present a case which was initially suspected to be a right atrial tumor because of a large filling defect in the right atrium on radionuclide angiocardiography but finally confirmed to be dissection of ascending aorta by computed tomography.

Congenital absence of the lower sternum, defect of the abdominal wall, defects of the anterior diaphragm, pericardial defects and cardiac anomalies had been described as a syndrome by Cantrell et al. Developing mechanism of the syndrome was embryologically defined. These defects arise apparently from combined anomalies of developing of the dorsal mesoderm. The authors present two cases of Cantrell's syndrome developed in one day old and eight months old female patient in which angiocardiography was done at the Department of Radiology, Seoul National University Hospital.

Anomalous origin of the right coronary artery from the pulmonary artery is a rare congenital anomaly that has generally been found incidentally during autopsy or surgery. Sudden death may occur without antecedent symptoms in apparently healthy, asymptomatic patients and hence operation is recommended when the lesion is recognized. As opposed to the more frequent anomalous origin of the left coronary artery from the pulmonary artery, only a few children with this anomaly have been reported to have undergone surgical treatment. This report describes a 2-year old patient whose diagnosis was made by echocardiography, confirmed by angiocardiography, and successfully corrected by reimplantation of the anomalous coronary artery into the aorta.

The coronary arteries are also subject to congenital anomalies of both minor and major consequence. Hemodynamically significant primary anomalies of the coronary arteries are those which alter myocardial perfusion. There are four major types : coronary artery fistula, origin of the left voronary artery from the pulmonary artery, congenital coronary stenosis or atresia and origin of the left or right coronary artery from the opposite sinus of Valsalva with subsequent passage of the vessel between the aorta and right ventricular infundibulum. Minor anomlies are the variation of the origin of the coronary arteries from the aorta with normal distal circulation. We can see more coronary anomalies associated with congenital cardiac anomalies, probably representing a circulatory response to the primary intracardiac defect. We present a total of 76 cases of congenital coronary anomalies, reviewing 3946 cases of angiocardiography or selective coronary arteriography, performed during last 8 years at Sejong General Hospital.

BACKGROUNDIsolated dextrocardia is a rare phenomenon and usually associated with multiple cardiac anomalies. This study was to evaluate the accuracy of diagnosis of isolated dextrocardia by using angiocardiography and to compare it with the results of surgery.

METHODSThe clinical data of 27 cases of congenital isolated dextrocardia were collected to understand the diagnostic approaches to the major cardiac anomalies. All cases underwent angiocardiography followed by palliative or curative surgery. The diagnosis was compared by angiocardiography relying on segmental analysis with the pathological features observed in surgery.

RESULTSThe results of angiocardiography of 22 patients were the same as the pathological features observed during surgery, including one case with congenital left ventricular diverticulum was inadvertently omitted in angiocardiograhy. There were significantly dissimilar diagnoses between angiocardiograhy and post-operation in 5 patients, including anatomical corrected transposition of great arteries misinterpreted as corrected transposition of the great arteries in 1, complete transposition of great arteries misinterpreted as corrected transposition of the great arteries in 1, single ventricle misinterpreted as double-outlet right ventricle in 1, and anatomical double-outlet left ventricle misinterpreted as corrected transposition of the great arteries in 2. Misdiagnostic rate of angiocardiograhy was almost 20%.

CONCLUSIONSAngiocardiography is of great significance in the diagnosis and classification of isolated dextrocardia. However, because of the intricacy of cardiac anomalies of isolated dextrocardia, atrial angiography and double oblique projection are needed to improve the accuracy of diagnosis to support surgical treatments.
