Objective To evaluate the clinical result of using osseointegratedimplants to retain removable orbital prostheses in repairing orbital defects. Methods Two patients with orbital defects caused by orbitaltumor were treated. Each of them got 4 implants. After average 6 months, we performed the secondary operation. After 7 weeks, we took impressions to make the implant-retained prostheses. The magnetic attachment was adopted. The prostheses were made of polysiloxane material(Factor II,Lakeside,Ariz). Results Both of the patients got the successful facial prostheses and were followed up 2 and 8 years respectively. All the implants were integrated well. There were no apparent inflammatory reactions in the soft tissue around percutaneous implants. The patients were satisfied with the facial appearance. Conclusion Implant-retained orbital prostheses are safe and effective in repairing orbital defects.
ObjectiveTo explore the operative strategy after palliative shunt for correcting congenitally corrected transposition of great artery (cTGA) patients with left ventricular outflow tract obstruction (LVOTO) and cardiac malpostion.MethodsWe retrospectively analyzed the clinical data of 54 patients with onsecutive cTGA with LVOTO and cardiac malpositon from June 2011 to May 2019. The patients were devided into two groups. There were 24 patients (16 males and 8 females at mean age of 5.4±2.2 years) who underwent one and a half ventricle repair as a one and half ventricle group. And there were 30 patients (19 males and 11 females at age of 8.6±6.2 years) who underwent one ventricle repair operation as a one ventricle group. Follow-up data were collected by telephone interviews.ResultsThere was no statistical difference in systemic atrioventricular valve regurgitation and systemic ventricular ejection fraction between the two groups (P>0.05). Compared with one and a half ventricle group, the cardiopulmonary bypass time (CPB) time, mechanical ventilation time and intensive care unit stay were significant shorter than those in the one ventricle group (P<0.05), but prolonged pleural effusions developed more frequently in the one ventricle repair group (P<0.05). There was no in-hospital death but 1 follow-up death in each group. The follow-up time was 49 (17-38) months in the one and half ventricle group at follow-up rate of 93.9%, and 47 (12-85) months at follow-up rate at 90.9% in the one ventricle group. One and a half ventricle group had better systemic ventricular ejection fraction (EF) than that in the one ventricle repair group. And the rate of heart function (NYHA) class Ⅲ and class Ⅳ in one and a half ventricle group was lower than that in the ventricle group. No significant difference of survival and freedom from re-intervention probability between the two groups was found.ConclusionFor patients of correction of cTGA with LVOTO and cardiac malposition after palliative shunt, the one-and-a-half ventricular repair procedure is ideal operative strategy.
ObjectiveTo analyze the results of surgical treatment of severe aortic stenosis in infants.MethodsFrom August 2012 to December 2019, 28 infants undergoing aortic valvuloplasty in our hospital were selected, including 22 males and 6 females, aged 62.00 (47.00, 82.50) d. The baseline characteristics of the patients, postoperative complications and follow-up results were analyzed.ResultsTwenty (71.43%) patients had bicuspid aortic valves. Five (17.86%) patients had heart failure and two (7.14%) patients used prostaglandin before surgeries. Postoperative mechanical ventilation time was 25.00 (17.00, 62.75) h, ICU stay was 3.50 (2.00, 8.50) d and postoperative hospital stay was 10.00 (7.00, 16.50) d. Four (14.29%) patients got delayed recovery (ICU stay>14 d). One (3.57%) perioperative death was observed. The follow-up time was 55.00 (43.25, 82.25) months. No death was found during follow-up. Four (14.81%) patients underwent a second operation, including three (11.11%) patients with severe aortic stenosis, and one (3.70%) patient with severe regurgitation.ConclusionInfants with severe aortic stenosis are seriously ill and have a long postoperative recovery time, requiring early surgery. The postoperative follow-up results are satisfactory.
ObjectiveTo summarize the surgical experience of patients with anomalous left coronary artery from the pulmonary artery (ALCAPA) and intramural left coronary artery and analyze the early and mid-term clinical outcomes. Methods The infants with ALCAPA and intramural left coronary artery who underwent surgical treatment in Fuwai Hospital from January 2014 to September 2020 were retrospectively enrolled, and the clinical data of the patients were analyzed. Results A total of 10 patients were included. There were 8 males and 2 females, with a median age of 7.5 (3-46) months at surgery. The surgical techniques included coronary unroofing in 7 patients, coronary unroofing with coronary reimplantation in 2 patients, and coronary unroofing with ligation of left coronary artery ostium in 1 patient. Seven infants received additional procedures, including 5 mitral valve repair. Delayed chest closure was required in 2 infants, and no operative death or major complications occurred in the whole group. Postoperative chest radiograph showed that the mean cardiothoracic ratio was lower than that before surgery (0.62±0.05 vs. 0.67±0.06, P=0.006). Postoperative echocardiography indicated that the mean left ventricular ejection fraction was increased than that before surgery, but there was no statistical difference (38.7%±15.9% vs. 30.0%±16.1%, P=0.066). The follow-up was available for all 10 survivors, with an average follow-up time of 13-92 (46.6±25.0) months. During the follow-up period, the patients had no obvious symptoms, death, coronary complications or other major complications. The chest radiograph at last follow-up showed that the mean cardiothoracic ratio was further decreased (0.60±0.07 vs. 0.62±0.05, P=0.024). The echocardiography at last follow-up showed that the mean left ventricular ejection fraction was further improved (60.1%±9.3% vs. 38.7%±15.9%, P=0.002). Conclusion ALCAPA with intramural left coronary artery is a rare malformation. It can be treated with different surgical techniques with satisfactory early and mid-term outcomes.
ObjectiveTo analyze the mid-long-term outcomes of surgical balloon valvuloplasty (SBV) for right ventricular decompression in the treatment of pulmonary atresia with intact ventricular septum (PA/IVS).MethodsClinical data of consecutive 91 patients who were diagnosed with PA/IVS and underwent SBV in our institution from January 2005 to December 2017 were retrospectively analyzed, including 52 (57.1%) males and 39 (42.9%) females. The median age was 3 months (1 d, 24 months) and the median weight was 4.1 (2.5, 12.0) kg.ResultsThe SBV was performed in all patients, and 62 of whom received other simultaneous surgeries, including ligation of patent ductus arteriosus (PDA, 33 patients), ligation of PDA with modified Blalock-Taussig shunt (23 patients), ligation of PDA with bidirectional Glenn shunt (6 patients). There was no early postoperative death. The median follow-up time was 8.8 (2.5, 13.4) years, 4 patients were lost. There were 7 (8.0%) deaths and 1 (1.1%) patient with a re-SBV for pulmonary stenosis. The one and a half ventricular repair was performed in 5 (5.7%) patients and Fontan procedure in 2 (2.3%) patients. In addition, the mean Z-value of tricuspid valve annulus was −1.7±1.5, which was significant bigger than that before the operation (t=5.587, P<0.001).ConclusionSBV via right ventricular outflow tract for right ventricular decompression in the treatment of PA/IVS is safe and reliable. The majority of patients can receive biventricular repair instead of single ventricular palliation by SBV with individually customized shunt.
ObjectiveTo summarize our experience of critical congenital heart diseases treatment system for the newborn and to report its surgical results.MethodsWe reviewed the clinical data of 97 neonates with congenital heart diseases who admitted to pediatric cardiac center from January 2019 to August 2020 in our hospital. The patients were divided into a prenatal and postnatal diagnosis and treatment integration group (integrated group, n=41), and a postnatal diagnosis and rapid admission by green channel group (non-integrated group, n=56).ResultsThe age of admission in the integrated group was younger than that in the non-integrated group (3.0 d vs. 11.0 d, P<0.001), and the weight was lighter (3.3±0.4 kg vs. 3.6±0.6 kg, P=0.006), operation age was younger (13.0 d vs. 17.5 d, P=0.004), proportion of palliative surgery was smaller (2.4% vs. 8.9%, P=0.396), time for ventilator assistance was longer (153.0 h vs. 65.0 h, P=0.020), hospital mortality was lower (0.0% vs. 7.1%, P=0.135). There was no significant difference in the follow-up (11.0 months vs. 12 months, P=1.000), out-of-hospital mortality (2.4% vs. 1.8%, P=1.000) and total mortality (2.4% vs. 8.9%, P=0.396) between the two groups.ConclusionPrenatal and postnatal diagnosis and treatment integration can significantly shorten the diagnosis and the hospitalization interval of newborn, that surgical intervention could be performed timely. It can reduce the risk of death before surgery but need longer time for recovery after surgery. Patients with postnatal diagnosis and admitted hospital through green channel also can get perfect results if surgical intervention is performed timely.
ObjectiveTo summarize the reoperation experience for complete atrioventricular septal defect (CAVSD) with severe left atrioventricular valve regurgitation (LAVVR) by standardized mitral repair-oriented strategy.MethodsFrom 2016 to 2019, 11 CAVSD patients underwent reoperation for severe LAVVR by standardized mitral repair-oriented strategy at Fuwai Hospital, including 5 males and 6 females with a median age of 56 (22-152) months. The pathological characteristics of severe LAVVR, key points of repair technique and mid-term follow-up results were analyzed.ResultsThe interval time between the initial surgery and this surgery was 48 (8-149) months. The aortic cross-clamp time was 54.6±21.5 min and the cardiopulmonary bypass time was 107.4±38.1 min, ventilator assistance time was 16.4±16.3 h. All patients recovered smoothly with no early or late death. The patients were followed up for 29.0±12.8 months, and the echocardiograph showed trivial to little mitral regurgitation in 5 patients, little regurgitation in 5 patients and moderate regurgitation in 1 patient. The classification (NYHA) of cardiac function was class Ⅰ in all patients.ConclusionStandardized mitral repair-oriented strategy is safe and effective in the treatment of severe LAVVR after CAVSD surgery, and the mid-term results are satisfied.
ObjectiveTo summarize the clinical outcomes and experience of surgical treatment for patients with complete atrioventricular septal defect (CAVSD) above the optimal age for surgery.MethodsWe retrospectively reviewed clinical data of 163 simple type CAVSD patients less than 7 years who underwent operations in Fuwai Hospital from 2002 to 2013. The patients were divided into a normal group (n=84, including 37 males and 16 females with an average age of 7.6±2.7 months) and an over-age group (n=79, including 30 males and 49 females with an average age of 34.6±19.6 months) according to whether the age was more than 1 year.ResultsThe average aortic cross clamp time (88.3±24.4 min vs. 106.1±35.4 min, P<0.001) and cardiopulmonary bypass time (123.6±31.1 min vs. 142.6±47.1 min, P=0.003) were statistically different between the two groups. During the follow-up period (the normal group 53.3±43.9 months, the over-age group 57.2±48.2 months), there was no statistical difference in all-cause mortality (10.7% vs. 8.9%, P=0.691), the incidence of moderate or severe left atrioventricular valve regurgitation (16.7% vs. 21.5%, P=0.430) and reintervention rate (3.6% vs. 0.0%, P=0.266) between the two groups. No left ventricular outflow tract obstruction and complete atrioventricular block occurred in both groups.ConclusionFor CAVSD children above the optimal age, rational surgical treatments can also achieve satisfying results.
Objective To summarize the reoperation experience for mitral regurgitation with leaflet augmentation in children. Methods From 2018 to 2022, the patients who underwent reoperation for mitral regurgitation with leaflet augmentation after atrioventricular septal defect repair or mitral valve repair in Fuwai Hospital were retrospectively collected. The characteristics of mitral valve disease, key points of surgery and short and mid-term follow-up results were analyzed. Results Finally 24 patients were enrolled, including 6 males and 12 females with an average age of 49.1±29.1 months. The time interval from the primary valve surgery to the reoperation was 24.9±17.0 months. The cardiopulmonary bypass time was 150.1±49.5 min and the aortic clamp time was 94.0±24.2 min. There was no early death. The average follow-up period was 20.3±9.1 months. During the follow-up period, the mortality rate was 4.2%, the rate of reoperation was 4.3%, and the rate of moderate or severe mitral regurgitation was 13.0%. The left ventricular ejection fraction was 62.6%±6.7%. In addition, the mean left ventricular end-diastolic dimension was 35.8±7.8 mm, which was significant smaller than that before the operation (t=4.858, P<0.000 1). Conclusion The application of leaflet augmentation is a safe and effective treatment option with good results in the short and mid-term, which thus provides a good technical option for pediatric patients with recurrent mitral regurgitation.
