A 4-year-old, neutered male Shih-tzu dog weighing 5.4 kg was referred due to anorexia and chronic coughing. Based on history, physical examination, laboratory tests, radiographic findings, echocardiography, and bronchoscopic examination, the dog was diagnosed as tracheobronchial foreign body. The foreign body was steamed rice debris, which was removed by bronchoalveolar lavage (BAL) with vacuum suction of bronchoscopy. Bacterial and fungal culture of collected BAL fluid was negative. Baermann test for lungs parasites also was negative. The dog was treated with bronchodilator, antibiotics, anti-inflammatory agent, and mucolytics for 7 days. Appetite increased and coughing sign was clearly improved after removal of foreign body and medical therapy. This case report describes that bronchoscopic techniques are available for the evaluation and management of airway foreign bodies.

A 45 year-old man who suffered with palpitation and dyspnea for 3 years visited our hospital. He was dianosed as mitral insufficieny due to isolated cleft mitral valve in anterior mitral leaflet on the basis of transthoracic echocardiogram In our case edges of the cleft were relatively thin and smooth. The entire length of the cleft was sutured with 5-0 Prolene? interrupted sutures. We report a case of direct suture repair in a patient with isolated cleft in anterior mitral valve leaflet.

The patient was a 30-day-old female infant with symptoms of severe dyspnea and cyanosis, when she was admitted to the ER. The echocardiography revealed DORV with subpulmonary VSD, and the diagnosis of Taussig-Bing anomaly was made. Two days after admission, an urgent operation was performed. The operation consisted of intraventricular tunnel repair and arterial switch operation. She was discharged, and after checking her chest X-ray through OPD, there was no interval change of cardiomegaly. She was then re-admitted, and the angiography revealed coactation of aorta. We performed a resection and end-to-end anastomosis of aorta. She is currently in good condition 11 months postoperatively.

Ebsteins anomaly is a rare congenital cardiac malformation that is the downward displacement of the septal and posterior leaflets of the tricuspid valve into the ventricular apex, aresulting in the formation of an atrialized portion of the right ventricle. In most patients, symptoms such as cyanosis and progressive heart failure occur during the adolescence or young adulthood. The associated anomalies include ventricular septal defect, transposition of the great arteries, and malformation of the mitral valve. An 8-months-old male with Ebsteins anomaly, ventricular septal defect, and duplication of the mitral valve orifice successfully underwent operation with VSD patch closure. Postoperatively, cardiac size was significantly reduced and tricuspid regurgitation was trivial in echocardiography He has been doing well without any cardiac medication during the 18 months follow up after operation.

A 52 day-old male infant who had Taussig-Bing anomaly with coarctation of the aorta underwent initial palliative Damus-Kaye-Stansel (DKS) procedure including arch reconstruction because of suspected intramural coronary artery, size discrepancy of great arteries, potential subaortic stenosis, refractory pneumonia, and severe congestive heart failure. Total repair was done 44 months later, which was composed of VSD patch closure, DKS take-down, and arterial switch procedure, We report a successful case of DKS take-down and arterial switch operation for the reuse of native aortic and pulmonary valves rather than Rastelli-type procedure in a patient with Taussig-Bing anomaly having palliative DKS procedure.

배경: 승모판막 질환에 동반된 심방세동의 경우 그 기간이 길면 승모판막 질환을 수술하여도 동성 율동으로 전환될 가능성이 매우 적다. 본 연구는 승모판막 질환에 동반된 심방세동에 대한 변형 Maze 수술후 장기 결과와 심방세도의 재발에 미치는 요인을 조사 하고자 하였다. 대상 및 방법: 1990년부터 1996년까지 승모판막 질환과 동반된 심방세동으로 외과적 요법을 시행받은 35명의 환자를 대상으로 하였다. 심방세동의 평균 유병기간은 평균 7.7$\pm$4.5년이었고 수술은 승모판막 대치술 34례(재수술 3례)와 승모판막 성형술 1례를 시행하였고 승모판 질환 수술 외에 동반 수술로는 삼첨판륜 성형술 4례, 삼첨판막 대치술 3례 였다. 심 방세동에 대한 수술은 좌측 폐정맥 부위는 격리하지 않는 변형 Maze 수술을 시행하였다. 수술 후 동성 율동으로 회복여부, 심방세동의 재발에 미치는 요인과 장기 결과를 분석하였다. 결과: 수술 직후 2례를 제외한 33례(93.9%)에서 동성율동으로 돌아왔으나 수술 후 퇴원 전에 12례에서 심방세동이 재발되었다. 수술환자중 1례에서 수술 후 3일에 동성 정지에 따른 심정지가 발생하여 소생되었으나 뇌손상으로 수술 후 15일에 사망하였다. 심방세동이 재발된 경우 수술 후 약 2개월에서 6개월 사이에 항부정맥 약물(mquinidine)과 전기적 제세동으로 치료하여 12례중 10례에서 동성 율동으로 돌아온 환자는 항부정맥 약물을 모두 중단하 였으며, 수술 후 3년에서 9년(평균 71.1$\pm$17.5개월) 추적 관찰 중 9례에서 심방세동이 재발되어 장기간 동성 율동이 유지된 환자는 34명중 25명으로 73.5%이었다. 승모판 질환이 있던 환자에서 수술 후 심방세동의 재발에 미치는 요인들을 조사한 결과 수술전 심방세동의 기간(동성율동 유지군 : 재발군=6.3년 : 10.3년, P=0.008)과 수술 전 단순 흉부 X선상 심흉비율(0.58 : 0.72, p=0.009)은 통계학적으로 유의하게 나타났으나 심초음파 검사상 좌심방의 직경(57.2mm : 77.4mm, p=0.106)은 통계학적 유의성이 없었다. 결론: 심방세동이 있는 환자에서 동반 질환 수술시 병행하여 수술한다면 정상 동성 율동으로 회복될 기회를 증가시킬 수 있는 유용한 수술법으로 생각된다. 그러나 수술후 재발률을 감소시키기 위하여 적절한 술기의 변형에 대한 연구와 약물요법의 병행을 고려하여야 할 것으로 사료된다.

Between December 1993 and March 1996, 75 patients had undergone ubannular procedures in mitral valve reconstruction. Their mean age was 45 years and they consisted of 28 males and 47 females. The cause of mitral disease in 75 patients were classified as follow : 29 cases were degenerative, 40 cases were rheumatic, 3 cases were congenital, 2 cases were infectious and 1 case was ischemic. Average number of mitral anatomical lesion per patient was 3.1 and we used average 1.5 procedures on subannular structure in mitral valve per patient. Subannular procedures were chordae shortening 21, chordae transfer 22, new chordae formation 20, papillary muscle splitting 33, shortening of papillary muscle 2. Intraoperative transesophageal echocardiography was carried out for providing an immediate and accurate assessment of the adequacy of the reconstruction. There was no operative death. Patients have been followed up from 2 to 29months, mean 12.5. There were two failures that necessitated reoperation. The mean functional class (NYHA) was 3.19 preoperative and improved to 1.12 postoperatively. After mitral valve repair, the patients were improved hemodynamic, echocardiographic data. In conclusion, subannular procedure in mitral valve repair when feasible is stable and safe with a low prevalence of reoperation.

Background: Atrial septal defect (ASD) is the most common congenital cardiac anomaly, accounting for 30 percent of congenital heart disease detected in the adult. Many patients with ASD are well tolerated and reach adult without significant symptoms. The patients with ASD die 4th and 5th decades, but prolonged survival is not uncommon. In general, the survival depends on whether pulmonary hypertension develops during adulthood or not. The most common cause of death in the patients with ASD is right ventricular failure or arrhythmias. Materials and methods: From January 1988 to June 1997, 33 cases of ASD underwent open heart surgeries in our hospital. Among them, 31 cases were adult ASD, and 2 tricuspid regurgitation, 1 pulmonic stenosis, 1 mitral regurgitation, 1 tricuspid regurgitation, and 1 coronary artery disease were combinded. All of the patients underwent surgical repair using autologus pericardial patch or direct closure. Results: The postoperative course was smooth and uneventful. Most of the patients showed significant improvement in ECG finding, hemodynamic profile, radiologic finding, and echocardiography, after surgery. Conclusions: Conclusively, most of the ASD should be closed even in patients over the age of 60 years, and early surgical repair must be done to prevent pulmonary hypertension, right ventricular failure, and arrythmias.

With the introduction of new cardiac prosthesis, it behooves surgeons and cardiologists to monitor its performance carefully. ATS (Advancing The Standard) prosthetic valve has been used first in Guro hospital in Korea, since August 1994. Between August 1994 and July 1995, 21 patients received 28 ATS prosthesis(9 aortic, 19 mitral).19mi1ra1 valves were implanted through the "Extended Transseptal Approach" 10 were ma e and 11 were female, ranging from 20 to 54 years of age(Mean age : 37 years). The follow up period 126 patient-months(mean 6.1 months), varied from 1 month to 12 months. NYHA functional class was improved significantly, from $2.9\pm0.7$ preoperatively to $1.4\pm0.5$ postoperatively. Ejection fraction was also improved from $55.5\pm6.1%$ preoperatively to 59.8 $\pm7.4%$ postoperatively. Lactic dehydrogenase(LDH) was used as an indicator of hemolysis. The value of LDH changed from 483.3 $\pm$ 162 lUlL preoperatively to $527\pm274$ lUff postoperatively with no clinical significailce. Valve related complications, such as thromboembolism, valve thrombosis, anticoagulant related hemorrhage and prosthetic valve endocarditis did not develop except one anticoagulant related intracranial hemorrhage. There were no mortalities. This experience encourages us to continue using the ATS prosthetic valve, and this study will help those patients who need to have their heart valves replaced. replaced.

Papillary fibroelastoma is a rare benign tumor of the heart. A 21-year-old man presented with dyspnea on exertion and echocardiogram showed a small round mass attached to the anterolateral papillary muscle. After excision of the mass, including anterior papillary muscle, chordae tendinae, and anterior leaflet, he underwent mitral valve re-placement with a mechanical valve. He was discharged on anticoagulant therapy without further problems.
