We report on the application of a venovenous type extracorporeal membrane oxygenator (ECMO) in high-risk tracheal procedures in six cases consisting of five patients with tracheal stenosis. An ECMO should be helpful for preventing respiratory emergency during a tracheal procedure.

A case of congenital tricuspid stenosis in 24 year old male patient is presented. The lesion was successfully corrected with prosthetic valve replacement and closure of atrial and ventricular septal defects. Especially, this is the first reported case of successful large prosthetic valve replacement to a small annulus in tricuspid valve.

The Rastelli operation has been a standard procedure for repairing complete transposition of the great arteries combined with a ventricular septal defect and pulmonary stenosis. Yet this procedure has several shortcomings, including the risk of incurring left ventricular outflow tract obstruction on long-term follow-up. In this regard, aortic translocation has recently been regarded as a potent alternative to Rastelli's operation. We report here on a case of complete transposition of the great arteries that was combined with an inlet-extended perimembranous ventricular septal defect and pulmonary stenosis in a 2-year-old boy. All the problems were successfully repaired using the aortic translocation technique. Postoperative echocardiography showed a straight and wide left ventricular outflow tract.

Background: Superior vena cava (SVC) stenosis during follow-up is a major concern after heart transplantation, and many technical modifications have been introduced. We analyzed the surgical results of the SVC intima layer-only suture technique in heart transplantation. Methods: We performed SVC anastomosis with sutures placed only in the intima during heart transplantation. We measured the area of the SVC at 3 different points (above the anastomosis, at the anastomosis, and below the anastomosis) in an axial view by freely drawing regions of interest, and then evaluated the degree of stenosis. Patients who underwent cardiac computed tomography (CT) at 2 years postoperatively between June 2017 and May 2020 were included in this study. Results: We performed heart transplantation in 41 patients. Among them, 24 patients (16 males and 8 females) underwent follow-up cardiac CT at 2 years postoperatively. The mean age at operation was 49.4±4.9 years. The diagnoses at time of operation were dilated cardiomyopathy (n=12), ischemic heart disease (n=8), valvular heart disease (n=2), hypertrophic cardiomyopathy (n=1), and congenital heart disease (n=1). No cases of postoperative bleeding requiring intervention occurred. The mean CT follow-up duration was 1.9±0.7 years. At follow-up, the mean areas at the 3 key points were 2.7±0.8 cm², 2.7±0.8 cm², and 2.7±1.0 cm² (p=0.996). There were no SVC stenosis-related symptoms during follow-up. Conclusion: The suture technique using only the SVC intimal layer is a safe and effective method for use in heart transplantation.

A lower laryngeal and upper tracheal stenosis that is of idiopathic origin is occasionally seen. It is called an idiopathic tracheal stenosis. These circumferential fibrous stenosis is rare and they are most often located in the subglottic larynx and extend to varying distances predominantly in young women. Because of the unknown nature of the disease process and uncertainty about its future progression, patients were approached conservatively. Recently, surgical resection and reconstruction have been increasingly performed, as favorable results were obtained. Three female patients with dyspnea were admitted. For two patients, they were diagnosed this conditions as bronchial asthma by mistake. All patients were performed computed tomography and bronchoscopy. For two patients with subglottic stenosis, subglottic resection was performed by cervical collar incision, and for the other one patient with distal tracheal stenosis, tracheal resection was performed by right posterolateral thoracotomy. A diagnosis of idipathic tracheal stenosis was confirmed by postoperatively pathologic finding. For one case, because of anastomosis site infection and restenosis, a whole tracheal exposure was performed by cervical collar incision and median sternotomy. And reoperation was peformed successfully.

Over a 12 months period, we treated 2 cases with discrete subaortic stenosis caused by membranous band. In one patient, who was 19 years old woman, the echocardiograms showed the discrete membrane and idiopathic hypertrophic subaortic stenosis [IHSS . She underwent transaortic myotomy and mymectomy simultaneously band resection. Other case of 11 year old boy with discrete subaortic stenosis only underwent membrane resection. Both patients had an uneventful hospital course, but 19 year old woman showed remained pressure gradient in follow up echocardiograms.

This case describes a tracheal stenosis complicated by endobronchial truberculosis. A 50-year-old female with progressive dyspnea was referred to us for the management of long segmental tracheal stenosis. Treatment modalities for tracheal stenosis include open surgical resectin and reconstruction, mechanical dilation, laser resection, and placement of an airway prosthesis. The following is a report of a successful treatment of a long segmental tracheal stenosis through a tracheal augmentation and the use of al Bovine pericardium. This technique may provide a relief from tracheal stenosis.

Tetralogy of Fallot with subarterial ventricular septal defect is known to be relatively common in the Far East. Among the 140 consecutive patients who underwent repair for tetralogy, 15 [10,7@] had this variant form of tetralogy. Though the degree of pulmonic stenosis seems only mild or moderately severe because of the absence of infundibular septum and relatively large size of pulmonary arteries in this type of tetralogy, it has a special surgical implication that a patch widening of the right ventriculotomy is necessary in every case to avoid the postoperative subpulmonic stenosis. A morphological and surgical features of tetralogy with subarterial VSD are presented.

The half-turned truncal switch (HTTS) operation has been reported as an alternative to the Rastelli or $r{\acute{e}}paration$ $\grave{a}$ $l^{\prime}{\acute{e}}tage$ ventriculaire procedures. HTTS prevents left ventricular outflow tract (LVOT) obstruction in patients with complete transposition of the great arteries (TGA) with a ventricular septal defect (VSD) and pulmonary stenosis (PS), or in those with a Taussig-Bing anomaly with PS. The advantages of the HTTS procedure are avoidance of late LVOT or right ventricular outflow tract (RVOT) obstruction, and of overstretching of the pulmonary artery. We report the case of a patient who underwent HTTS for TGA with VSD and PS, in whom there was no LVOT obstruction and only mild aortic regurgitation and mild RVOT obstruction, including observations at 12-year follow-up. Our experience with long-term follow-up of HTTS supports a solution for late complications after the Rastelli procedure.

Airway management is difficult problem in severe tracheal stenosis. A total airway obstruction during the procedure resulted in a fatal outcome. We suggest a tracheostomy assisted with an emergency bypass system as a possible method for avoiding this complication.
