A total of 54 patients with mitral stenosis were treated in the Dept.of Thoracic and Cardiovascular Surgery. Chonnam National University Hospital, during the 17-year period from Jan., 1962 to June, 1978. There were 35 men and 19 women with sex ratio of 1.8 : 1. The age of the patient varied widely from 15 years of the youngest to 48 years of the oldest. Preoper ative functional levels according to N.Y.H.A. classification were class II in 19% of cases, class III in 69%, and class IV in 12%. 53 patients were underwent closed operations; 43 cases had closed digital mitral commissurotomy and 10 cases had closed dilator mitral commissurotomy, Hospital mortality was I case (1. 9%). Results of operations were good and excellent in 48cases(91%).Most of the survivors left hospital in a good and improved condition.

Bilateral coronary artery to pulmonary artery fistulas are very rare anomaly. Echocardiography, cardiac catheterization and coronary angiography of two patients having chest pain and dyspnea showed bilateral coronary to pulmonary artery fistulas. One patient had left anterior descending coronary artery stenosis and the other patient had cystic tumor. We report the good results of the surgical treatment of two patients with bilateral coronary to pulmonary artery fistulas.

Congenital esophageal stricture is infrequent disease entity and usually occurs in the mid esophagus. Tracheobronchial remnants in the esophagus causing esophageal stricture are extremely rare, and only few cases were reported in the literature. During last 17 years the authors experienced a case of congenital esophageal stricture due to ectopic tracheal cartilaginous ring who was complicated by peptic esophageal stricture 11 years after esophagogastrostomy. During thoracotomy we thought that the patient had unual achalasia of the esophagus, and couldn`t perform cardiomyotomy because of firm ring encircling the lower esophagus just above the hiatus. The patient was operated on lower esophagectomy including cardia and esophagogastrostomy at his age of two and a half years. Postoperatively the patient did well for 11 years but later he developed intermittent regurgitation without substernal burning, and reoperated under the diagnosis of peptic esophageal stricture-lower esophagectomy, proximal gastrectomy, esophagogastrostomy and Heineke-Mikulicz pyloroplasty with good operative result.

Lung sound analyer which can provide an objective diagnosis of patients with pulmonary and bronchial disorders is designed. For the purpose of power spectrum analysis, adaptive digital filtering technique and TM - S320C25 DSP chip is used. As a results, adaptive lattice Wiener filter could eliminate heart sounds with a few of 10th order and on the distribution of power spectrum each patterns has shown in normal vescicular breathy from 100 Hz to 200 Hz, in crackle sound from 100 Hz to 400 Hz, in wheeze sound from 150 Hz to 600 Hz.

Cases of pyogenic spondylodiscitis are relatively rare diseases that concern 2-7% of total cases of osteomyelitis. Owing to the low frequency and initial nonspecific nature of signs and symptoms, diagnosis is often delayed up to 2-6 months. If the proper treatment is not established due to a diagnostic delay, there is a possibility of a serious neurologic deficit and spinal instability. We report two cases of infectious spondylodiscitis which were misdiagnosed as compression fracture and spinal stenosis respectively. They could be correctly diagnosed after MRI and laboratory test and under the recovery state after an antifungal and antibiotic medication. Special careful attention during the diagnostic procedure is a really important step considering the diagnostic delay and its resultant unsatisfactory outcome.

근래에 장기간 보조 호흡이 많아지고 사고로 인한 기관손상이 증가함에 따라 기관 협착증의 빈도가 증가하고 있다. 기관 재건술에 사용하는 여러 조직 중에서 연골막은 유연하고 신생연골을 생성할 수 있으며 감염에 저항성이 있고 점막화가 빨라 이상적인 조직으로 알려져있다. 저자들은 실험동물로 각각 10마리의 가토를 사용하여 유리자가 이개연골막과 혈관경을 가진 자가이개 연골막을 이용한 기관재건술을 시행하고 8주후에 신생연골 형성능력을 정량적으로 비교 분석하여 다음과 같은 결과를 얻었다. 1) 기관 결손 부위는 두 실험군 모두에서 잘 재건되었다. 2) 이개연골막은 기관 결손을 재건하는데 유용한 조직임이 확인되었다. 3) 유리자가 이개연골막 이식군에서는 평균 0.15mm의 신생연골을 생성한 반면 혈관경을 가진 자가이개 연골막 이식군에서는 평균 0,45mm를 생성하여 더욱 효과적이었다.

Whatever a surgeon choose aortic prosthesis in aortic stenosis, it will always provoke some degree of obstruction to flow due to its smaller effective orifice area to tissue annulus. Occasionally, we meet small aortic annulus to his or her body surface area in aortic valve replacement. The small annulus remains a problem in that both tissue and mechanical prosthesis have significant pressure gradients between LV and aorta in resting or exercising states. In these circumstances, diverse surgical procedures, such as tilting disc prosthesis, supraannular position of aortic prosthesis, and enlargement of aortic root [including aortoventriculoplasty, translocation of aortic valve, & double outlet of LV by valved conduit], were applied. We experienced one case of aortic stenosis with small aortic annulus. Systolic pressure gradients between LV & aorta were 90 mmHg. Diameter of annulus was 19 mm. So we performed patch enlargement of aortic root by Manouguian and AVR with St. Jude medical valve 23 mm.

Congenital esophageal stenosis is a rare disease in childhood. By virtue of its complex embryological development, the esophagus is the site of many congenital abnormalities. Congenital Esophageal stenosis is one tenth as rare as tracheoesophageal fistula with esophageal atresia and is very rare in the cervical esophagus, which mostly occurred below mid-esophagus. Congenital esophageal web may be caused by the resorption failure of the epithelium following the vacuolization stage in embryonic development in the esophagus. Recently, we experienced 1 cases of congenital esophageal web, as the symptoms of life-long dysphagia. According to her history of dysphagia, radiologic and clinical findings, her esophageal stenosis was considered as congenital. For dilatation and relief of dysphagia, she underwent the Heineke-Mikulicz type of esophagoplasty. The results of surgical treatment were relatively good without any clinical events. So we reported it with its literature review.

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.

Laryngotracheal stenosis is one of the most troublesome diseases in the Em field. Subglottic stenosis can be treated by a cricoid augmentation with rib cartilage. In case of tracheal stenosis, the treatment of choice is by tracheal end-to-end anastomosis after resection of the stenotic site. However, in case of subglottic stenosis combined with tracheal stenosis, it is hard to manage. Even though several methods(such as thyrotracheal anastomosis) have been tried, they have some limitations too much excision of normal trachea and too much pulling up of the trachea after resection of the stenotic lesion. The authors have managed two cases of laryngotracheal stenosis as an anterior and posterior subglottic augmentation with an autologous cartilage graft and laryngotracheal anastomosis. The first few weeks after the operation, we could do a decannulation successfully, but in one case the patient developed restenosis. Even though one case was unsuccessful, the authors believe that this method could be used in the treatment of laryngotracheal stenosis.
