온전한 심실중격을 가진 폐동맥판막무형성증(absent pulmonary valve syndrome with intact ventricular septum, APVS with IVS)은 매우 드문 선천성 심장 질환이다. 신생아의 경우 확장된 폐동맥에 의한 기도폐쇄와 이로 인한 심한 호흡곤란증으로 높은 사망률을 유발한다. 이에 대한 해결책으로 여러 약물치료 및 여러 고식적 수술, 폐동맥 판막 삽입, 폐동맥 축소술(reductive angioplasty of pulmonary artery) 등이 사용되었다. 본원에서는 동맥관 결찰술, 폐동맥 축소술, 폐동맥 판막 재건술(pulmonary valve reconstruction) 및 심방중격결손 봉합술을 시행하여 좋은 결과를 얻었다.

Primary intimal sarcoma of the pulmonary artery is a rare disease and there has been no report of any case originating from the pulmonary valve. Recently we experienced a 62 year-old female patient who had a primary intimal sarcoma of the pulmonary valve with distal metastasis. She was brought to medical attention due to exertional dyspnea facial edema productive coughing and general weakness for 1 month. Chest CT and echocardi-ography suggest an acute pulmonary thromboembolism or tumor. Exploration showed a large polypoid mass arising from the pulmonary leaflets and multiple masses on distal pulmonary arteries. We replaced the pulmonary valve and reconstructed the pulmonary artery. She received radiotherapy 1 month postoperatively and now 4 months after surgery she has begun receiving chemotherapy.

Tetralogy of Fallot associated with a single pulmonary artery is a rare cardiac anomaly. In previously reported cases, left pulmonary arteries were absent except 2 cases. Congenital absence of the pulmonary valve is a rare anomaly too. In the majority of cases, this lesion is associated with TOF. TOF associated with a single pulmonary artery and absent pulmonary valve is a very rare anomaly and only less than 20 cases were reported in the literatures. We have operated on one patient with TOF associated with absent right pulmonary artery and rudimentary pulmonary valve, a variant of absent pulmonary valve, and report this case with review of the literatures.

A 51-year-old male was admitted to the hospital with complaints of fever and hemoptysis. After evaluation of the fever focus, he was diagnosed with pulmonary valve infective endocarditis. Thus pulmonary valve replacement and antibiotics therapy were performed and discharged. He was brought to the emergency unit presenting with a high fever (> $39^{\circ}C$) and general weakness 6 months after the initial operation. The echocardiography revealed prosthetic pulmonary valve endocarditis. Therefore, redo-pulmonary valve replacement using valved conduit was performed in the Rastelli fashion because of the risk of pulmonary arterial wall injury and recurrent endocarditis from the remnant inflammatory tissue. We report here on the successful surgical treatment of prosthetic pulmonary valve endocarditis with an alternative surgical method.

원발성 폐동맥 육종, 특히 폐동맥 판막에서 기원한 폐동맥 육종은 극히 드물다. 35세 남자 환자가 노작성 호흡곤란과 전신무력감을 주소로 입원하였다. 흉부 컴퓨터 단층촬영, 흉부 자기공명영상, 심장초음파 검사, 폐동맥 조영술상 주 폐동맥 및 양측 폐동맥의 내강에서 커다란 종괴가 관찰되었다. 폐동맥의 원발성 악성 종양으로 생각하고 심폐순환하에 절제를 시행하였다. 폐동맥 판막의 후엽에서 기원한 것으로 보이는 종괴가 폐동맥 판막의 하부에서부터 주폐동맥 및 양측 폐동맥까지 뻗어 있었고, 폐동맥 내막절제술을 통한 종괴의 절제 및 폐동맥 판막 치환술을 시행하였으며, 병리조직학적 검사에서 폐동맥 육종으로 진단되었다.

The use of the patient`s pulmonary valve for replacement of the patient`s diseased aortic valve was introduced and developed by Mr. Donald Ross. The long term benefits of having a normal, fully viable, trileaflet semilunar valve in aortic position was demonstrated. A 38 year old male had histories of failures of previously implanted aortic prosthetic valves twice and evidence of progressive heart failure. At operation, aortic root abscess was found; the abscess extension to adjacent structures and partial valve dehiscence had occurred. The patient underwent replacement of the aortic root with autologous pulmonary valve, autologous pericardial patch repair of left ventricuar outflow tract and recontruction of the right ventricular outflow tract and pulmonary artery with prosthetic valved conduit. Postoperatively, the patient recovered well. Postoperative doppler echocardiography demonstrated minimal central regurgitation in new aortic valve. Aortic root replacement with pulmonary autograft in a patient of recurrent aortic root abscess and false aneurysm of left ventricuar outflow tract was experienced and reported with follow up echocardiography.

We evaluated 68 patients with mitral valve disease who underwent mitral valve replacement from April, 1986, to December, 1988. Among them 20 patients showed increased systolic pulmonary arterial pressure greater than 60 mmHg and postoperative hemodynamic data were obtained in 19 patients average 13 months after mitral valve replacement. The results were as followings. 1. Average pulmonary systolic pressure decreased from 84.8$\pm$4.5 preoperatively to 33. 0$\pm$1.9mmHg postoperatively[P<0.001]. 2. Average pulmonary vascular resistance index decreased from 1425$\pm$148 preoperatively to 287+35.8 dyne * sec * cm2 * m postoperatively[P<0.001]. 3. Average cardiac index rose from 1.927$\pm$0.169 preoperatively to 2.625$\pm$0.159 L/min/m2 postoperatively [P <0.005]. This study shows that pulmonary hypertension and the increased pulmonary vascular resistance index due to mitral valve disease can regress significantly after mitral valve replacement.

호흡곤란을 주소로 내원한 17세 환자가 대동맥 및 폐동맥 사엽성 판막을 보이며 심방중격결손과 폐동맥 판막 협착증이 발전되어 소심막을 이용한 심방중격결손 봉합 및 폐동맥 판막 교련절개술을 시행하였다. 대동맥 판막과 폐동맥 판막이 모두 사엽성 판막을 보이는 경우는 매우 드문 선천성 기형으로 폐동맥 사엽성 판막이 대동맥 사업성 판막보다 9배정도 많다. 본 증례는 Hurwitz and Roberts 분류법상 대동맥판막은 A형, 폐동맥판막은 B형이었으며 대동맥 판막기능은 정상적이었고 폐동맥 판막 협착증을 보였다.

Purpose: The purpose of this study is to get basic user guidelines of safe and efficient bag-valve-mask application on patients having abnormal pathophysiological pulmonary conditions. Methods: This study was performed by pre-qualified 35 EMS junior and senior students. Participants were instructed to compress ambulatory bag randomly about half, one-third, one-fourth within different airway resistance and pulmonary compliance. Resultant tidal volume and pulmonary wedge pressures on RespiTranier monitor were analysed in relation to pulmonary physiologic index. Results: At least over half compression of bag guaranteed minimal tidal volume regardless of pulmonary conditions. There was no increase of pulmonary wedge pressure above the level of barotrauma on half compression at any pulmonary conditions. Conclusion: Assisted ventilation with ambulatory bag on patients with pathological pulmonary conditions should be over half compressed regardless of respiratory disease entity.

A 17-month-old intact male Cocker Spaniel was presented with primary complaints of severe ascites, exercise intolerance, and diarrhea. Diagnostic studies revealed tricuspid and pulmonic regurgitation on phonocardiogram, right ventricular enlargement on the electrocardiogram, typical right cardiac enlargement signs on the thoracic radiography and tricuspid valve malformation and marked enlargement of the right atrium and right ventricle on the echocardiography and tricuspid and pulmonary regurgitation on the color spectral echocardiography, suggesting tricuspid valve dysplasia and pulmonary hypertension. Using angiography and cardiac catheterization, pulmonary hypertension was ruled out. Further echocardiographic study revealed membranous valvular structures cranial to pulmonary annulus causing pulmonary regurgitation. Based on these findings on the diagnostic investigation, the case was diagnosed as tricuspid valve dysplasia complicated with pulmonic regurgitation. The dog was medically managed with furosemide, enalapril, nitroglycerine transdermal patch and pimobendan after the ascitic fluid removal.
