Objective To observe the toxic and side effects during the continuous hyperthermic peritoneal perfusion chemotherapy (CHPPC).Methods Abdominal paracentesis and catheterization were performed under ultrasound guidance, then CHPPC was carried out, which was in temperature of 42-44 ℃ for 1 h. The changes of body temperature, heart rate, blood pressure, saturation of blood oxygen and respiratory frequency were recorded in 109 patients during and after perfusion, meanwhile symptoms and physical signs of abdominal region and system status such as abdominal tenderness, rebound tenderness were observed. Results There were no significant differences of body temperature, heart rate, blood pressure, saturation of blood oxygen or respiratory frequency between before and after perfusion (Pgt;0.05). There were 25 patients with abdominal pain, but in which only 3 patients with symptoms of acute abdomen, 26 patients with gastrointestinal symptoms, 20 patients with myelosuppression, and others (22 cases) with aches of puncture position which were released by symptomatic treatment. Conclusion There are less toxic and side effect and better tolerance in patients with CHPPC application 1 month after operation.
Objective To evaluate the outcome of surgical repair of interrupted aortic arch (IAA) combined with anomalies. Methods We retrospectively analyzed the clinical data of 48 patients with IAA combined with anomalies undergoing one-stage biventricular repair in Shanghai Children's Medical Center from November 2006 to April 2016. There were 25 males and 23 females with a median age of 29 d (range, 8 to 91 d) and a mean weight of 3.80±0.67 kg. All patients underwent end-to-end anastomosis with patch augmentation, and relief of left ventricular outflow tract obstruction (LVOTO) was performed in 11 patients. Results In IAA children with anomalies, 39 (81.3%) suffered noncomplex lesions and 9 (18.8%) complex lesions. Mean follow-up was 72.1±19.7 months for 38 patients. There were 6 in-hospital deaths and 3 patients died during follow-up. The early survival rate was 87.5%, 5-year rate 83.3% and 10-year rate 81.3%. Reintervention was required in 10 patients, including 8 with subsequent LVOTO and 2 with anastomotic stenosis. Conclusion End-to-end anastomosis with patch augmentation is effective for IAA.
ObjectiveTo summarize the cardiac-vascular abnormalities and clinical results in patients with Fontan operation for heterotaxy syndrome. MethodWe retrospectively analyzed the medical records of 81 patients who underwent the Fontan operation with heterotaxy syndrome between September 2008 and September 2013. There were 49 male and 32 female patients at age of 3.79 (range 2.07-13.02) years with preoperative room air saturation of 81% (range 63%-97%) and weight of 14.8 (10.0-36.0) kg. ResultsThere were 70 patients in the right atrial isomerism group and left in 11 patients. Dextrocardia was seen in 16 patients, and single atrium in 50 patients. Single ventricle was found in 44 patients, conotruncal defects in 40 patients, pulmonary stenosis in 72 patients, pulmonray atresia in 8 patients, common atrioventricular valve in 61 patients, and bilateral superior vena cava in 54 patients. The staged Fontan procedure was applied in 57 patients and one stage in 24 patients. Operation strategies were included intra/extracardiac conduit (n=17), extracardiac conduit (n=48), lateral tunnel (n=14) and direct cavopulmonray connection (n=2).There were 15 early deaths. Postoperative complications included low cardiac output in 15 patients, hepatic insufficiency in 35 patients, renal insufficiency in 55 patients required peritoneal dialysis and arrhythmia in 28 patients. The room air saturation was 89% (range 78%-98%) before discharge and time of follow-up was from 2 months to 6 years in 64 patients. Thromboembolic events were found in 2 patients who had accomplished conduit replacement operation. ConclusionCompared with reported literatures in western countries, heteraotaxia patients are mostly with right atrial isomerism. Fontan palliation is still the main treatment option and strict indication was needed for satisfactory clinical results.
Objective To compare the postoperative outcomes of modified single-patch technique and one-and-a-half-patch technique for complete atrioventricular septal defect (CAVSD) with a large ventricular component (>1 cm). Methods We retrospectively reviewed clinical data of 79 CAVSD patients with a large ventricular component (>1 cm) in Shanghai Children's Medical Center from January 2005 through January 2016. There were 37 males, 42 females with a median age of 8 months (range, 1.5 months to 10.2 years). Among the patients, 45 patients (20 males, 25 females) with a median age of 6 months(range, 1.5 months to 10.2 years) received modified single patch technique and 34 patients (17 males, 17 females) with a median age of 5.3 months (range, 2.5 months to 8.3 years) underwent one-and-a-half-patch (1.5-patch) technique. All the patients complicated with complex malformation such as double outlet of right ventricular, single ventricle, and transposition of great arteries were excluded. Results The mortality and reoperation rate in modified single-patch group were higher than those of the one-and-a-half-patch group. There were 2 postoperative early deaths in the modified single-patch group (4.4%). Among them, one patient died of postoperative valvular regurgitation and heart pump failure. The other one died of respiratory failure caused by severe pneumonia. There were 3 reoperations. Two patients performed valve plastic surgery because of valve regurgitation and one patient because of residual ventricular septal defect. There was no death and reoperation in the one-and-a-half-patch technique group. No left ventricular outflow tract obstruction and atrioventricular block in both groups were developed. Conclusion The 1.5-patch technique is an attractive clinical option in CAVSD patients with a large ventricular component.
ObjectiveTo explore the short-term follow-up clinical effect of transcatheter valve-in-valve implantation treatment for mitral bioprosthesis deterioration.MethodsThe single center data of elderly patients with mitral valve bioprosthetic dysfunction who received transapical J-Valve intervention between January 2019 and May 2020 were reviewed and summarized. After the informed consent was signed, single lumen endotracheal intubation was performed under general anesthesia in hybrid operating room. The left intercostal small incision was used to explore the apical area. Fluoroscopy and three-dimensional esophageal ultrasound were used to guide the puncture needle. Then the guide wire entered the left atrium through the mitral valve biological valve. The catheter was exchanged, and the rigid support wire was exchanged. The reverse loaded J-Valve system was guided and implanted into the biological mitral valve with beating heart. The appropriate implantation depth was adjusted, and stent valve was released under rapid pacing. Post balloon dilation of the valve was performed if necessary.ResultsFrom January 2019 to May 2020, transcatheter J-Valve implantation was completed in 20 patients with mitral valve dysfunction and high-risk evaluation of routine thoracotomy and cardiopulmonary bypass (the Society of Thoracic Surgeon score above 6). In terms of the type of the the mitral bioprosthesis, there were 6 cases of Hancock valves, 7 cases of Perimount valves, 6 cases of Epic valves, and 1 case of Baxiter valve. In terms of the size of the the mitral bioprosthesis, there were 2 cases of size 29 valves, 11 cases of size 27 valves, and 7 cases of size 25 valves. One valve fell into the left ventricle at early stage. One patient had mild valve displacement during operation, and a second valve was implanted at the same time. The success rate of valve-in-valve implantation was 95%. The length of stay in intensive care unit was less than 6 h in 5 cases, 6-24 h in 13 cases, 24-48 h in 1 case, and more than 48 h in 1 case. No patient’s postoperative mitral regurgitation was moderate or above. The mean mitral valve pressure gradient was (5.2±2.3) mm Hg (1 mm Hg=0.133 kPa). Patients recovered well after the valve-in-valve implantation treatment, with no death within postoperative one month. One patient died of infection and multiple organ failure during follow-up after one month. Other patients recovered smoothly without serious complications.ConclusionsThe clinical effect of J-Valve intervention in the treatment of mitral valve bioprosthetic dysfunction through apical approach is good. The implantation can be completed under beating heart, avoiding cardiopulmonary bypass and routine thoracotomy cardiac arrest, which is worthy of further observation and follow-up.
ObjectiveTo summarize our experience and clinical effect of surgical treatment of Stanford type A aortic dissection (TAAD) involving an aberrant right subclavian artery (ARSA). MethodsFrom March 2009 to January 2016, 14 patients with TAAD involving an ARSA (acute TAAD, n=10; chronic TAAD, n=4) underwent operation under hypothermic cardiopulmonary bypass combined with selective antegrade cerebral perfusion in our center. There were 11 male and 3 female patients with a mean age of 46.07±8.45 years. A total of 13 patients (13/14, 92.86%) underwent stented elephant trunk procedure combined with total arch replacement (Sun's procedure). The remaining patient (1/14, 7.14%) underwent partial aortic arch replacement combined with Bentall procedure without ARSA revascularization. ResultsThe average operation time, cardiopulmonary bypass time, aortic cross-clamping time and selective cerebral perfusion time was 7.89±1.80 h, 208.43±28.84 min, 117.64±23.30 min, and 30.50±10.15 min, respectively. No operation-related deaths occurred. However, two (14.29%) patients died on postoperative 5 d, 7 d, respectively in hospital. One patient required repeat thoracotomy for bleeding, one suffered temporary renal dysfunction and one renal failure (this patient had renal failure before surgery). The mean follow-up was 28.42±22.52 months with a follow-up rate of 100.00% (12/12). One patient died of heart failure and renal failure at 64 months after operation. The others were free from any aortic complications during follow-up. ConclusionsTAAD involving an ARSA should be clearly diagnosed before surgery, and treated by the optimal arterial cannulation and cerebral perfusion during operation. Repair of aortic dissection with Sun's procedure and revascularization of the ARSA can obtain satisfactory clinical outcomes in patients with TAAD involving an ARSA.
ObjectiveTo summarize and analyze the risk factors and management of artificial valve slippage in transcatheter aortic valve implantation (TAVI).MethodsWe retrospectively analyzed the clinical data of 131 patients undergoing TAVI surgery in our center from September 2017 to May 2019, including 62 patients through transapical approach and 69 patients through transfemoral artery approach.ResultsA total of 131 patients received TAVI surgery, among whom 4 patients had slipped during the operation, 2 patients via transfemoral artery approach, and another 2 patients via transapical. The average age was 77±9 years with one female (25%). Preoperative evaluation, higher position and poor coaxial were main risk factors for valve slip in TAVI.ConclusionValve slippage is also a serious complication in TAVI surgery. Reasonable and effective treatment can avoid thoracotomy.
ObjectiveTo evaluate the validity of European System for Cardiac Operative Risk Evaluation (EuroSCORE) Ⅱ for predicting in-hospital mortality and prolonged ICU stay after Sun's procedure (total aortic arch replacement with stented elephant trunk implantation) for Stanford type A aortic dissection (STAAD). MethodsClinical data of 384 STAAD patients undergoing Sun's procedure in Beijing Anzhen Hospital between February 2009 and February 2012 were retrospectively analyzed, including 228 (59.38%) patients with acute STAAD. Accoding to EuroSCORE Ⅱ to predict postoperative mortality, all the patients were divided into a low-risk group, a medium-risk group, a high-risk group and an extremely-high-risk group. There were 296 patients including 52 females in the low-risk group with their age of 45.39±10.75 years, 70 patients including 19 females in the medium-risk group with their age of 47.67±11.26 years, 13 patients including 5 females in the high-risk group with their age of 53.08±4.94 years, and 5 patients including 1 female patient in the extremely-high-risk group with their age of 41.60±11.08 years. All the patients received Sun's procedure under deep hypothermic circulatory arrest and antegrade selective cerebral perfusion. EuroSCORE Ⅱ was used to predict postoperative mortality and prolonged ICU stay. ResultsIn-hospital mortality was 8.07% (31/384). Mean length of ICU stay was 3.06 days. Length of ICU stay of 42 patients was longer than 7 days. For low-risk group, the predicted mortality was lower than the actual mortality. For medium-risk, high-risk and extremely-high-risk groups, the predicted mortality was higher than the actual mortality. EuroSCORE Ⅱ showed unsatisfactory discriminatory ability to predict postoperative mortality and prolonged ICU stay. The area under ROC curve were 0.49 and 0.52 respectively. The calibration was also poor for predicting postoperative mortality and prolonged ICU stay (P<0.001). ConclusionsEuroSCORE Ⅱ is not satisfactory for predicting mortality and prolonged ICU stay after Sun's procedure for the treatment of STAAD. A new risk evaluating system specific for STAAD is needed.
