Comparative Study[Long-term results of valve replacement in the right side of the heart in congenital heart disease--comparative study of bioprosthetic valve and mechanical valve].
Valve replacements in the right side of the heart (TVR and PVR) were done on 16 patients with congenital heart disease, mainly tetralogy of Fallot and Ebstein anomaly. Including reoperations, 19 operations were performed on them and 20 artificial valves were inserted. Ten mechanical valves (7 St. ⋯ Calcified bioprosthetic valve occurred in one patient with I-S valve 8.5 years after the implantation. Five-year complication-free rate was 87.5 +/- 11.7% for bioprosthesis, whereas it was 50.0 +/- 15.8% for mechanical valve (p less than 0.056). It is concluded that the bioprosthesis is the first choice for the valve replacement in the right side of the heart in congenital heart disease.

Case Reports[A case of thyroid carcinoma required the incision of the thyroid cartilage for inserting the silicone T tube after extensive tracheal resection and reconstruction].
A 57-year-old female with thyroid carcinoma, who had developed tracheal stenosis, underwent extensive tracheal resection and reconstruction. After the tracheal sleeve resection 5.2 cm in length, primary tracheal reconstruction was performed. Although complication did not occur at the anastomotic site, the patient had dyspnea due to cord dysfunction by bilateral recurrent nerve paralysis. ⋯ The patient inserting the T tube through the laryngeal stoma had no dyspnea and no aspiration about two years after the operation in spite of palliative operation. It seemed likely that the trouble that tracheostomy could not be done would occur in some patients who had undergone extensive tracheal resection and reconstruction. But the insertion of silicone T tube through the laryngeal stoma provided a satisfactory result for airway problem.

Case Reports[A case of intralobar pulmonary sequestration associated with abnormal connection between the aberrant artery and the pulmonary artery].
The patient was a 5-year-old girl and had a history of recurrent pneumonia. Angiogram demonstrated that the aberrant arteries arising from descending aorta communicated with left pulmonary A10 where the multi-lobulated cystic lesion was seen by chest X-P. ⋯ The connection between aberrant arteries and pulmonary artery in this case might be caused by the chronic inflammation in the sequestrated lung. We found 4 case reports in which the communication between aberrant arteries and pulmonary artery was evident.
