Coarctation of the aorta and interrupted aortic arch are congenital anomalies affecting the aortic arch. Because of the poor natural prognosis, many patients will need early surgical repair or even emergency surgery. With the improvement of the surgical techniques, cardiopulmonary bypass techniques and perioperative intensive care, surgical mortality has now dramatically decreased. However, aortic arch restenosis, left ventricular outflow tract obstruction and long-term hypertension are problems that may be still encountered during the follow-up period. By reviewing large amounts of literature and discussing among experts, we achieved a consensus on many aspects of the management strategy. We hope this consensus will help Chinese colleagues further improve the overall surgical outcomes of coarctation of aorta and interrupted aortic arch.
Objective To summarize the experiences of surgical treatment of sinus venosus atrial septal defect （SVASD）. Methods There were 32 patients of SVASD, all of them were associated with totally or partially right anomalous pulmonary venous connection. There were 25 cases of superior SVASD, 22 cases underwent double-patch procedure, 3 cases underwent Warden procedure. In 7 cases of inferier SVASD, 3 cases of Scimitar syndrome underwent ASD repair by pericardial patch and at the same time the anomalous pulmonary vein was divided and reimplanted to the posterior wall of left atrium, 4 cases of them underwent single-patch ASD repair. Results The surgical results were satisfying and no patient died, 28 patients were in sinus rhythm and echocardiography showed neither obstruction of caval vein and right pulmonary vein nor residual interatrial shunt. Conclusion SVASD mostly associated with right anomalous pulmonary venous connection according to its special anatomic structure. Preserving the function of sinus node and avoiding of obstruction of caval vein should be routinely considered when superior SVASD was repaired. The heart function of Scimitar syndrome should be followed-up for a long time for it usually associated with right lung hypoplasia.
ObjectiveTo study the examinees' cognitive level of the X-ray radiation, and to provide references for popularizing radiation protection knowledge. MethodWe chose patients who were checked in the Department of Radiology in our hospital between August 30 and October 29, 2013 as our study subjects, and carried out investigation by anonymous questionnaires. The investigation content included the respondents' basic information, ways to obtain the radiation knowledge, how well the patients knew about the fundamental radiation knowledge and their attitudes towards radiological examination and so on. A total of 2 315 patients were investigated, and 2 315 questionnaires were issued. Finally all questionnaires were retreated. ResultsAmong the 2 315 patients, 2026 (87.52%) knew the radiation symbol and 1 821 (78.66%) knew that X-ray radiation was harmful to the human body. Different age, gender, occupation, educational level and previous X-ray examination made significant differences in the fundamental knowledge on X-ray (P<0.05) . Attitudes towards X-ray examination was significantly different due to different age, occupation, and educational level (P<0.05) . Most examinees got the X-ray fundamental radiation knowledge from the publicity and medical staff in hospitals. ConclusionsTo make the examinees keep right attitudes and behaviors in radiographic examination, further effective methods of popularizing the basic knowledge of radiation should be carried out. Those publicity and medical staff in hospitals are the main force in the popularization of radiation knowledge.
Tricuspid regurgitation (TR) is a common but often neglected valvular heart disease. Growing evidence has highlighted its association with poor prognosis and the complexity of its management. In recent years, transcatheter tricuspid valve intervention (TTVI) has emerged as a promising minimally invasive approach, with accumulating evidence supporting its safety and short-term efficacy. Transcatheter approaches offer a new therapeutic alternative for high-risk TR patients, but the clinical indications for TTVI are still being refined. This review summarizes recent advancements in TTVI technology, compares the indications for surgical and transcatheter therapies, and discusses the critical role of right heart function and pulmonary circulation in therapeutic decision-making.
The technique of transcatheter aortic valve implantation has become increasingly mature. Although the transapical approach has a certain degree of minimally invasive trauma, it still has the characteristics such as heart beating without cardiopulmonary bypass, and the low technical requirements of catheter guide wire. In particular, the valve path is short and coaxial, which is easy to manipulate, and pure regurgitation and stenosis can be easily operated and are not subject to the limit of peripheral artery stenosis. It is still one of China's main approaches for transcatheter aortic valve replacement. Its perioperative management still has specific features and differs from the femoral artery approach. In addition, there is little relevant literature abroad. Therefore, domestic experts in this field were organized to discuss the development of perioperative management specifications to provide reference and techniques support for developing this field in China and further improve the quality of clinical operation and perioperative management. It will provide more safe and more effective medical services to these patients.
Abstract:Objective To summarize the experiences of single stage repair of interrupted aortic arch （IAA） associated with cardiac anomalies. Methods From Jan. 2000 to Dec. 2005, 48 patients admited in hospital and 35 patients were operated, the mean age at operation was 1.1 years. The associated anomalies included 23 cases of ventricular septal defect, 2 cases of transposition of great arteries, 3 cases of aortopulmonary window with aortic origin of right pulmonary artery, 2 cases of truncus arteriosus, 2 cases of double outlet right ventricle, 2 cases of stenotic fifth arch and 1 case of aberrant origin of right subclavian artery with mild hypoplastic decending aorta. Among them, 34 patients underwent single stage repair and 1 kid underwent palliative correction. Results There were 4 surgical deaths. The sequelae included one diaphragm paralysis and one 3rd degree of atrioventricular block. Only 5 kids recurred mild stenosis of aortic arch anastomosis and 2 death occurred during 3 months to 4 years of follow-up. Conclusion Though early surgical mortality for primary single stage repair is now relatively low, if appropriate interventions has been accomplished during perioperative period, but outcomes of IAA remain of concern, especially in patients with associated lesions.
