We present an unusual case of vascular sling, tracheal stenosis by complete cartilaginous ring, and aberrant left subclavian artery with right aortic arch that underwent successful surgical repair for the sling. These abnormalities were suspected from unusual multiple indentations found on esophagogram. Complete preoperative diagnosis was established with chest computerized tomogram combined with angiography.

Double-outlet left ventricle with ventricular septal defect and pulmonary stenosis was conventionally repaired with extracardiac conduit or pulmonary artery translocation. Here, we report an anatomically repaired double-outlet left ventricle without extracardiac conduit or pulmonary artery translocation in an 11 month old patient who had undergone palliative systemic-pulmonary shunt at a nonatal period. The location of ventricular septal defect, both great arteries and coronary arteries made it possible to reconstruct the right ventricular outflow tract using on-lay patch after incision and undercutting the tissue between the ventriculotomy and the pulmonary arteriotomy.

PURPOSE: This study was performed to evaluate whether a relationship may exist between transient peripheral pulmonary stenosis and the closure of the ductus arteriosus in term infants. METHODS: A total of 69 healthy full-term infants had pulmonary artery and ductal color Doppler flow velocity assessment performed at of 10 hours age(group I), 1-2 days of age(group II), and 1-2 weeks of age(group III). We measured the following variables at the main pulmonary artery, the right pulmonary artery and the left pulmonary artery ' diameter, flow velocity and velocity- time integral, acceleration time(AT), ejection time(ET). RESULTS: Diameters of right and left pulmonary arteries of group III were smaller than that of group I(P<0.01). There was no difference between groups in terms of RPA/LPA diameter ratio. There was significant difference between groups in terms of right and left pulmonary artery peak flow velocities. Right pulmonary artery(RPA)/left pulmonary artery(LPA) peak velocity ratio of group III was lower than that of group I and group II. There were significant differences between groups in terms of the right and left pulmonary artery peak velocity-time integral. RPA/LPA peak velocity-time integral ratio of group III are lower than those of group I. There were significant differences between groups in terms of right and left pulmonary artery acceleration time/ejection time(P<0.05). There were no significant differences between groups in term of RPA/LPA AT/ET ratios. The increase of peak flow velocity % of RPA and LPA in groups II and III is higher than that of group I. CONCLUSION: Ductal constriction could explain increases in left pulmonary arterial flow velocities in full term infants.

PURPOSE: Among the several transcatheter devices of PDA occlusion, Rashikind device was the most extensively experienced, but it had risk of occluder embolism and incomplete occlusion of PDA, approximately 27%. The authors used Duct-Occlud , made of 0.028 inch stainless steel coil. The coil is double cone-shape in released state, and used in streched condition through 4F implantation catheter for ductus occlusion. We are to report the short-term result of PDA occlusion using Duct-Occlud. METHODS: Six patients with internal ductal diameter of less than 3.5mm were selected for ductus occlusion. The Duct-Occlud was selected as follows : the diameter of aortic end was same as aortic ampulla, and the length was slightly shorter than that of ductus. The streched coil was introduced into descending aorta through implantation catheter, and the remaining coil was released in ductus and pulmonary artery subsequently. Postprocedure aortic angiogram was obtained and echocardiography was performed at 1day, 1 week, 1 month and 3 month after the procedure. RESULTS: Except one hourglass type, all the other PDA were tunnel shaped. The range of internal diameter of ductus was 0.83-2.4mm, the length 5.36-P12.4mm, and Qp/Qs 1.04-1.67. Three cases required repositioniong of coils, while the others were successful in one procedure. The residual shunts were resolved at 1 day in most cases, but two cases in 1 month after the procedure. There were no complications, such as coil embolism, migration, or pulmonary stenosis. CONCLUSIONS: In small PDA with internal diameter of less than 3.5mm, transcatheter occlusion using Duct-Occlud is easy, safe and accurate, except with high cost.

A five-month-old boy who had undergone previously transcatheter balloon atrioseptostomy at 3 days of age for complete transposition of the great arteries with ventricular septal defect and pulmonary stenosis underwent pulmonary root translocation with the Lecompte maneuver. This operation has the advantages of maintaining pulmonary valve function, preserving the capacity for growth, and avoiding problems inherent to the right ventricular to pulmonary artery conduit. This patient progressed well for 9 months postoperatively and we report this case of pulmonary root translocation with the Lecompte maneuver.

Acquired pulmonary artery stenosis which is secondary to tuberculosis is so rare that only a few scattered cases have been reported. We report one case of pulmonary stenosis caused by pulmonary tuberculosis.l A 50 year old man who gradually developed dyspnea was diagnosed as bilateral pulmonary stenosis, he underwent bypass surgery between the main diagnosed as bilateral pulmonary stenosis. he underwent bypass surgery between the main pulmonary artery and the right pulomonary artery with a 13mm Gortex ringed straight graft. The left pulmonary artery was too small to restore the perfusion. The patient was discharged on the 33rd day after the operation. Acquired pulmonary stenosis could be treated successfully with one-side pulmonary arery reconstruction.

Morphological evaluations accounting the associated anomalies were performed in the 60 cases of tricuspid atresia, diagnosed at Division of Pediatric Cardiology. The following results were obtained. 1) Twenty one out of the 6 cases had transposition of the great vessels, among which 8 cases were in complete A-transposition. 2) Seven cases were associated with pulmonany atresia, in 1 case, aorta arise from morphological right ventricle and in 6 case, aorta from morphological left ventricle. Pulmonary stenosis or pulmonary outflow obstruction was found in 52 cases except the rest 8 cases. 3) Four cases were associated with double outlet right ventricle and double outlet left ventricle in 1 case. In conclusion, for the classification of tricuspid atresia on the clinical basis, every possible interrelation of great vessels should be put into full consideration and pulmonary atresia, with very few exceptions, be separated as and isolated item due to the impracticability to verify the origin of pulmonary arteries.

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.

BACKGROUND: Since the nonsurgical treatment of mitral stenosis using a single balloon has been introduced by Inoue et al. in 1984. percutaneous mitral valvuloplasty has became an accepted therapeutic modality for selected patients with mitral stenosis. Zeibag et al. demonstrated the double balloon technique showed a better outcome than the single balloon in obtainning the optimal mitral valve area. On the other hand, there are several reports that single balloon technique was comparable with the double balloon technique. Therefore, there are still controversies in efficacy, benefit and complications between balloon techniques. METHOD: To compare the efficacy and complications of percutaneous mitral valvuloplasty with the double balloon or the Inoue balloon technique, 40 patients were studied consecutively by random method in selecting the balloon technique. RESULTS: In all cases, percutaneous mitral valvulopasty was performed successfully. Optimal outcome defined as mitral valve area larger than 1.5cm2 was obtained in 12 cases out of 16(75%) in double balloon group and 15 out of 24(63%) in Inoue balloon group(p=NS). Mitral valve area was significantly increased after valvulopasty in both technique but there was no different between both groups(Mean+/-SD ; 0.9+/-0.3 to 1.7+/-0.2 vs 0.9+/-0.2 to 1.9+/-0.2cm2). There were also hemodynamic improvement significantly in mean mitral gradient(MG). pulmonary artery pressure (PAP) and left atrial pressure(LAP) after PMV but there were no difference between groups (18+/-8 to 7+/-2 vs 21+/-13 to 9+/-4 mmHg for MG. 29+/-12 to 22+/-9 vs 28+/-9 to 18+/-5mmHg for PAP and 22+/-8 to 11+/-5 vs 21+/-6 to 11+/-4 for LAP respectively). Mitral requrgitation greater than grade 2 occurred in 2 cases of the double balloon group and one case of the Inoue balloon group(p=NS). New development of atrial shunt was found in 3 cases in both groups. CONCLUSIONS: The double and Inoue balloon techniques were quite comparable in immediate outcome and complications.

A 45 year-old-women with tracheal stenosis due to an endotracheal tumor was scheduled for tracheal reconstruction surgery. The stenotic lesion was located 1 cm above the carina, and was length of 4 cm and had a narrowest internal diameter of 0.4 cm. The length of such a stenotic segment and its narrowest internal diameter may pose lung ventilation problems before or during tumor resection, which may preclude a successful outcome. Thus, during tracheal reconstruction surgery a femoro-femoral partial cardiopulmonary bypass, self respiration, and pulmonary artery ligation were used. These measures improved oxygenation and cardiovascular stability, and tracheal reconstruction was successfully performed without complication.
