Ankyloglossia is the presence of a lingual frenulum, which can range from a mucous membrane band to a short and thick band and, in extreme cases, to fusion of the tongue to the floor of the mouth. The effects of such a condition, in addition to speech defects and occasionally restriction of sucking, including dental deformities, such as open bite, or even prognathism. Treatment is surgical. The preferred treatment is horizontal sectioning of the frenulum down to the lingual septum and then suturing of the mucosa. The main problem after the healing of surgical wound is adhesion and contracture. Adhesion restrict the movement of tongue like tongue-tie. Z-plasty at the site of incision can solve this problem by changing the direction of scar. We have experienced a patient with ankyloglossia with speech defect, who underwent frenuloomy by Z-plasty. So we present a surgical treatment of Ankyloglossia using Z-plasty and discuss the treatment with a review of literature.

Cor triatriatum is a variant of abnormal connection between the pulmonary vein and true left atrium, which is separated from accessory left atrium receiving pulmonary venous blood flow by fibromuscular diaphragm. Usually it is diagnosed after operation because difficulty in visualization of the diaphragm by conventional diagnostic tools. We experienced a rare entity of congenital heart disease diagnosed as car triatriatum with atrial septal defect and partial anomalous pulmonary venous return after completing operation, which was diagnosed as ASD with PAPVR preoperatively. Anomalous right pulmonary venous opening was located at right atrium, secundum type defect of atrial septum was present, and dual chambered left atrium without connection was also seen. Excision of the diaphragm and wide patch repair of ASD including right pulmonary vein were performed with good postoperative results. Herewith, we report this case with review of literatures.

Truncus arteriosus is one of the rare cyanotic congenital cardiac anomalies and thought to be result from complete or partial failure of trunco-conal septum. A single arterial trunk receiving blood from both ventricles supplies the coronary, pulmonary and systemic circulation. The symptoms were usually related to the degree of the pulmonary blood flow and functional status of truncal valve, and mostly appeared within the first two months of life. The prognosis is generally considered to be poor in spite of successful surgical correction. This report is a case of 13 years old female with type I truncus arteriosus, which was successfully corrected using a intracardiac Dacron tunnel graft[semilunar, 18mm] from VSD to the truncal valve, and a extra-cardiac lonescu-Shiley valved[20mm] Dacron conduit [21mm] from RV to the pulmonary artery[Rastelli operation].

양심방 점액종은 세계적으로도 대단히 드문 질환의 하나로 우리 나라에서는 그간 2례 만이 발표되었다. 저자들은 점액종으로부터 떨어져 나간 색전으로 인한 것으로 여겨지는 뇌 경색증의 증상으로 혼미한 의식을 보였던 60세 남자 환자의 수술 증례를 보고하고자 한다. 저자들의 경우, 점액종은 난원공의 서로 다른 위치에서 생기어 각기 다른 심방 으로 자라 있었고, 심초음파 검사로 진단 직후 곧바로 응급수술을 시행하였다.

본 논문에서는 TEM Cell 의 최적 설계방법을 제안한다. 임피던스 부정합을 최소화 시키기 위해 Cell 내부의 특성 임피던스를 $50{\Omega}$으로 유지하며, 동시에 중심 도체판(septum)의 길이와 도체판 날개(winglet)의 각을 변화 시킴으로써 내부 전자파의 균일도(Uniformity)를 최대로 하는 TEM Cell의 최적설계방법을 제안하며 (1+1)ES를 적용하여 시험영역을 최대로 하는 최적 설계 변수들을 제시한다.

The syndrome of anomalous muscle bundle dividing the right ventricle into two pressure chambers has been described by many authors. The malformation should not be confused with tetralogy of Fallot itself because the obstructive hypertrophic bands are usually proximal to the right ventricular infundibulum. One case [11 years old male] of double chambered right ventricle due to aberrant muscle bundle with intact ventricular septum is presented. The pressure gradient was 68 mmHg between inflow and outflow tracts of right ventricle on cardiac catheterization. On opening the right ventricle, there noted stenosis of outflow tract by infundibular membrane, hypertrophied anomalous muscle bundle, thickened moderator band & hypertrophied anterior papillary muscle. Open heart surgery was carried out with the aid of extracorporeal support, Anomalous muscle bundle [1.0 cm x 4.0 cm] and infundibular membrane were resected safely. The hypertrophied moderator band was cut at mid-portion and anterior papillary muscle was split vertically. The postoperative course was uneventful and discharged in good condition 2 weeks later.

Tetralogy of Fallot has shown its familial aggregation in several familial studies. This reported case is another example which occurred in a family in two brothers. They revealed no cytogenetic abnormalities, but the anatomical cardiac malformation of them showed much similarity, total conal defect in ventricular septum and .one had patent foramen ovale, the other atrial septal defect. The familial recurrence tendency of Tetralogy of Fallot as well as other congenital heart diseases could be explained on multifactorial inheritance as shown in many reports. In spite that we couldn`t find out any environmental trigger or teratogens, our case may be accepted on the base of multifactorial mechanism.

Thromboembolism is a major cause of morbidity and death following implantation of cardiac prosthetic devices. Effective systemic anticoagulation is very important. The presence of thrombus can often be detected by pulmonary edema associated with the disappearance of valve clicks. 2-D echocardiography and phonocardiography are also valuable tools. The most common treatment is reoperation and replacement after discovery early. We have experienced one death of fatal thromboembolism after St. Jude valve replacement was done in 48 years old male diagnosed of severe mitral stenosis. He was treated with warfarin, aspirin, ticlopidine for 10 weeks but died suddenly. At autopsy, valve dysfunction was seen due to organic thrombus arising from atrial septum and confirmed with microscopic findings.
