Congenital cystic disease of the lung is very rare and controversial disease. But in general is regarded as developmental anomaly. Occasionally failure of the primitive lung bud to develop combined with cardiac anomaly had been reported but it was very rare. Recently a case of cystic lung disease combined with pulmonic valvular stenosis was seen in this clinic with clinical pictures of nonspecific respiratory infection and X-ray finding very similar to that of far advanced pulmonary tuberculosis, destroyed left lung. This case was treated by closed pulmonic valvulotomy and left side pneumonectomy successfully.

A 4-year-old female Fox Terrier dog (weighting 8 kg) with history of severe abdominal distention and anorexia was presented to Veterinary Teaching Hospital, Gyeongsang National University. In physical examination, grade 4/6 systolic murmur heard at the left heart base. Electrocardiography showed right ventricular enlargement (right axis deviation and deep S wave) and right atrial enlargement (P pulmonale). Diagnostic imaging studies revealed hypertrophy of right ventricle, enlargement of right atrium and tricuspid regurgitation and turbulence in the pulmonary artery in right parastenal short axis view. Based on the diagnostic findings, the dog was diagnosed as a case of valvular pulmonic stenosis.

A 3-year-old, intact female, Shih-tzu dog was presented with a 15-day history of vomiting,depression, and anorexia. On physical examination, systolic ejection murmurs with precordial thril atthe left heart base were detected. A diagnosis of congenital pulmonic stenosis (PS) was made mainlyfrom the thoracic radiography, electrocardiography, and echocardiography. On complete blood counts andconfirmed that main pulmonary artery was tremendously buldged and electrocardiography was suggestiveof severe right ventricular hypertrophy. Echocardiographic findings revealed the pulmonic valve stenosiscontaining valvular dysplasia and poststenotic dilation. On Doppler echocardiography, ejection velocityof the lesion accounted for 3.38 m/sec, meaning mild velocity through the stenotic area. The dog'sproblem and resulted in death. However, there has been no reliable relation between PS and CRF. Primarymalformation of pulmonic valve was confirmed at necropsy after death.

4 년령 시쭈개 (체중 5.4 kg)가 심잡음과 운동불내성으로 내원하였다. 진단검사상 심한 폐동맥협착증으로 진단되었다 (우심실 유출로의 peak velocity of 6.4 m/s, 압력구배 165 mmHg). 본 환견은 3 cm (길이) ${\times}$ 1.5 cm (직경)의 Palmaz biliary stent를 이용하여 치료하였다. 시술후 환견의 폐동맥 협착증은 상당히 많이 개선되었다 (우심실 유출로의 of peak velocity가 3.0 m/s로 감소). 내원전 보였던 임상증상은 더 이상 보이지 않았지만 경미한 폐동맥 패쇄부전이 관찰되었다. 본 증례는 우리나라에서 최초로 시도된 스텐트를 이용한 폐동맥 협착증 증례이다.

This is report of two cases of annular constrictive pericarditis. Since January 1959 to December 1979 the authors experienced 48 cases of chronic constrictive pericarditis treated surgically at the Department of Thoracic and Cardiovascular Surgery, the National Medical Center in Seoul. These cases simulated valvular heart disease. One case, as mitral stenosis, revealed rumbling apical diastolic murmur [II/VI], atrial fibrillation and right ventricular hypertrophy pattern on E.C.G., the other, as infundibular pulmonic stenosis, presented pressure gradient between right ventricle and main pulmonary artery at infundibular level of 76 mmHg in systole. Both patients underwent operation successfully and one of them was assisted by E.C.C. during pericardiectomy and result was excellent. It is difficult to make the diagnosis of these conditions preoperatively so consideration about these might be important to make the diagnosis accurately.

Thirty-two cases of tetralogy of Fallot corrected totally using extracorporeal circulation in this department are presented during the period from April 1983 to Feb. 1986. Types of right ventricular outflow tract obstruction were a case of pulmonic valvular stenosis, 3 cases of infundibular stenosis, and 28 cases of combined type. There were associated anomaly such as 3 cases of pulmonary arterial hypoplasia, 7 cases of atrial septal defect, a case of left superior vena cava, and 2 cases of right side aortic arch. Transannular patch for right ventricular outflow tract reconstruction was necessary in 12 cases. Operative death was 6 cases and late death was a case, but other remaining cases followed up over 2 months carried out normal life.

생후 19일 된 남아가 안면 청색증과 과호흡을 주소로 내원하였다. 심 초음파 소견 상 B형의 대동맥 궁 단절과 후방 부정열형의 심실 중격 결손, 대동맥 판 협착을 보였다. 수술은 양심실 교정을 시행하였으며, 대동맥 판과 폐동맥 판 모두를 좌심실 유출로로 이용하고 신 대동맥 궁을 재건하고 Goretex graft를 이용하여 우심실 유출로를 재건하는 새로운 방법으로 하였다. 술 후 좌심실 유출로와 우심실 유출로 모두 협착없이 잘 유지되었다.

Four neonates with critical pulmonary outflow obstruction underwent emergency palliative operation between February 1988 and May 1989 at the department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital. There were three boys and one girl, the mean age was 12.25 days [ranging from 3 days to 26 days], and the mean body weight was 3,625 gm [ranging from 3,450 gm to 4,200 gm]. Two patients had severe pulmonic valvular stenosis with intact ventricular septum, a third had pulmonary atresia with intact ventricular septum, and another had pulmonary atresia with ventricular septal defect. All were cyanotic, showed arterial desaturation with metabolic acidosis, and had congestive heart failure. To relieve the pulmonary outflow tract obstruction, we performed transventricular pulmonary valvulotomy [Brock operation] with a mosquito clamp in all cases without extracorporeal circulation. Three patients survived the operation and showed satisfactory postoperative results. The patient who had pulmonary atresia with ventricular septal defect expired 5 days after surgery. We consider transventricular pulmonary valvulotomy [Brock operation] with a mosquito clamp as one of the preferable procedures for critical pulmonary outflow obstruction in the neonatal period.

Noonan증후군에서는 정상 핵형이면서도 Turner증후군과 같은 표현형과 다양한 형태의 지능저하, 양안격리증, 골격이상 및 선천성 심혈관계 이상과 같은 선천적 기형의 특징을 보인다. Noonan증후군의 2/3에서 심기형을 가지며, 그중 폐동맥협착이 반을 차지한다. Noonan증후군에서 폐동맥협착과 그외 다른 심기형을 가졌던 두 명의 환자 증례로 첫번째 환자는 31세 남자로 Noonan증후군의 특징적인 표현형을 보이면서 중증의 폐동맥 판막하협착과 난원공 개존증을 가지고 있었다. 두번째 28세 남자환자는 전형적인 Noonan증후군의 얼굴모양 과 저신장이었으며 폐동맥판 및 폐동맥판막하 협착을 동반하고 있었다. 상기 2례에서 모두 폐동맥판 교련절제와 우심실의 비후된 근육층을 제거하였고 첫번째 환자에서의 난원공 개존증은 일차봉합을 시행하였다. 술후 좋은 결과를 보였고 추적관찰중이다.

Forty nine patients [M: 31, F: 18], age from 2 months to 17 years [mean= 4.9 years], underwent operations, from April 1986 to December 1992, for the relief of subvalvular aortic stenosis in normal atrioventricular and ventriculoarterial connections.There were 4 anatomic types of subaortic stenosis : membranous in 29 cases [59.2%], fibromuscular in 11 [22.4%], diffuse tunnel type in 7 [14.3%], and miscellaneous in 2 cases. Thirty four patients [69.4%] had associated cardiac anomalies, of which ventricular septal defect was the most common [27 cases]. Other anomalies were patent ductus arteriosus, coarctation of the aorta, valvular aortic stenosis, double chambered right ventricle [DCRV], infundibular pulmonic stenosis, persistent left superior vena cava, and rigt aortic arch. Mean systolic pressure gradient between the left ventricle and ascending aorta was 26.4$\pm$17.6 mmHg : 13.1$\pm$17.6mmHg in the membranous type, 22.0$\pm$18.4mmHg in the fibromucular type, and 56.1$\pm$38.4mmHg in the diffuse tunnel type. Operative procedures were determined according to the type of subvalvular aortic stenosis : simple excision of subaortic membrane in the membranous type [29 cases], left ventricular myectomy with or without myotomy or fibrous tissue excision in the fibromuscular type [11 cases]. Among the 7 of diffuse tunnel type cases, ventricular myectomy was performed in 2 and a modified Konno operation was performed in 5 . Postoperative follow up was made with periodic echocardiography. The Mean postoperative follow up period was 33.8 months. There were 2 hospital mortalities [4.1%] and 2 late deaths. Residual stenosis remained in 3 cases and recurrence developed in 2 cases during the follow up period. 5 years actuarial survival rate was 91.8$\pm$3.9% and 5 year complication free rate was 72.3$\pm$10.4%. Conclusions : 1. Subvalvular aortic stenosis should be relieved completely as soon as possible when diagnosed, regardless of left ventricular outflow tract pressure gradient. 2. Good results were obtained using only simple excision of subaortic membrane in the membranous type of subaortic stenosis. However, aortoventriculoplasty [modified Konno prodedure] was necessary for good results in the diffuse tunnel type. 3. Periodic postoperative echocardiography was helpful in detecting the progression of residual stenosis and development of new stenosis.
