ObjectiveTo reveal the risk factors for delayed recovery and complications in infants with weight≤5.0 kg after surgical ventricular septal defect (VSD) closure.MethodsWe retrospectively reviewed a consecutive series of 86 patients with weight≤5.0 kg who were admitted to our institution for surgical VSD closure between January 2016 and July 2019, including 31 males and 55 females with an age of 17-266 (80.3±40.4) d and a weight of 2.5-5.0 (4.4±0.6) kg. The VSDs were divided into perimembranous (n=65, 75.6%), subaortic (n=17, 19.8%) and subaortic combined muscular types (n=4, 4.7%). Mechanical ventilation (MV) time≥24 h or ICU stay≥72 h were defined as delayed recovery. Death, sudden circulatory arrest, complete heart block requiring a permanent or temporary pacemaker implantation, neurological complications, reoperation (for residue shunt or valvular regurgitation), reintubation and diaphragmatic paralysis were considered as significant major adverse events.ResultsThere was no death, reoperation due to residual VSD or neurological complication. Totally 51 (59.3%) patients had MV timec≥24 h and 51 (59.3%) patients stayed in the ICU≥72 h. Two (2.3%) patients required temporary pacemaker and six (7.0%) patients required reintubation. During the follow-up of 3-36 (15.8±8.8) months, 1 patient died of pneumonia after discharge, 5 patients suffered mild tricuspid valve regurgitation and 1 patient suffered decreased left ventricular systolic function in the follow-up. No aortic valve injuries occurred.ConclusionFor patients whose weight≤5.0 kg, short-term results of surgical VSD closure are excellent. Low weight and age may prolong MV time; low birth weight and pulmonary hypertension may prolong ICU stay, but are not independent risk factors.
ObjectiveTo analyze the diagnosis and treatment of patients with ventricular septal defect complicated with infective endocarditis.MethodsWe retrospectively analyzed the clinical data of 40 patients with ventricular septal defect complicated with infective endocarditis in our hospital from 2001 to 2016. There were 25 males and 15 females, aged 20-62 (39.92±11.16) years. They were divided into two groups according to the duration from admission to surgery: a group A (an early operation group whose surgery was performed within 7 days after admission) and a group B (a conventional treatment group with the duration from admission to surgery>7 days). Among them, there were 27 patients in the group A including 15 males and 12 females with an average age of 39.56±11.80 years, and 13 patients in the group B including 10 males and 3 females with an average age of 40.69±10.13 years. All patients were examined by echocardiogram and blood bacterial culture to investigate their etiology, echocardiogram results and treatment status. And the clinical data of the two groups were compared.ResultsTwo patients died before operation in the group B, one died of heart failure, and one cerebral infarction. No reoperation during hospitalization, cerebral infarction, thromboembolism or other complications occurred. The ventilation time in the group A was significantly shorter than that in the group B (18.00±14.85 h vs. 31.00±29.57 h, P=0.015). There was no statistical difference in the extracorporeal circulation time, myocardial block time, or postoperative hospital stay between the two groups (P>0.05). After discharge, the patients continued antibiotic therapy for 3-6 weeks. Patients were followed up for 12-127 (75.74±6.01) months, 1 died of malignant tumors in the group A, 1 developed atrial fibrillation and 1 developed cardiac insufficiency in the group B, and the rest of patients did not complain of obvious discomfort. There was no residual shunt, recurrence of infective endocarditis, reoperation, postoperative stroke or thromboembolism.ConclusionPreoperative echocardiography and blood bacteriological culture are helpful for the diagnosis and treatment of patients with ventricular septal defect complicated with infective endocarditis. Early surgery is safe and effective for these patients, and can improve the long-term survival rate.
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.

Methods: From June1999 to December2008, the clinical data of 27 children suffering from PAVSD were analyzd. Male：16,female: 11. The ages ranged from 1.3 to 14 years, the average age is 6.08±3.73 years.All the children were final diagnosised by color Doppler echocardiogram and right catheterization.All underwent the radical correction under moderate hypothermic cardiopulmonary bypass. Results: There was no operative mortality. 25 cases were followed up for 6 months to 10 years, 1 case died of heart failure secondary to severe mitral regurgitation 3 months after the operation, 1 case had Ⅱdegree atrioventricular block , recovered 6 months later. 2 cases still had mild mitral regurgitation. Other cases lived and studied normally, their heart function is first class. Conclusion: Surgical treatment should be taken as soon as the diagnosis is confirmed. Shallow suturing repairing primum atrial defect and complete repairing mitral valve cleft are the key points of success and avoiding complications.
ObjectiveTo summarize the experience of totally thoracoscopic cardiac surgery for ventricular septal defect.MethodsClinical data of 449 patients undergoing totally thoracoscopic cardiac surgery for ventricular septal defect from May 2008 to December 2018 in Shanghai Yodak Cardiothoracic Hospital were analyzed retrospectively. There were 232 male and 217 female patients, aged from 3 to 55 years with a mean age of 17.3±11.2 years.ResultsAll the operations were completed successfully. Mean operative time was 2.4±0.3 h. The mean extracorporeal circulation time and aortic cross-clamp time was 64.2±11.6 min and 28.4±10.7 min, respectively. Mechanical ventilation time and intensive care unit stay was 6.9±3.8 h and 20.5±5.6 h, respectively. Postoperation drainage quantity was 213.1±117.2 mL. The hospital stay was 6.9±1.3 d. Intraoperative and postoperative complications occurred in 11 patients (2.4%), including 1 patient of intraoperative reoperation, 3 patients of reoperation for bleeding, 3 patients of the incision infection, 2 patients of small residual shunt, 1 patient of right femoral artery incision stenosis complicated by thromboembolism and 1 patient of right pleural cavity pneumothorax. The mean follow-up time was 72.2±33.9 months. During the period, there was no reoperation, but 2 patients of ventricular septal defect small residual shunt, 1 patient of mild-moderate mitral valve and 1 patient of mild-moderate aortic valve incompetence, respectively. During the period, heart function of the patients was NYHAⅠ-Ⅱ.ConclusionTotally thoracoscopic cardiac surgery for ventricular septal defect is a safe and effective treatment, with few serious complications, fast recovery for patients and good short to medium-term outcomes.
ObjectiveTo explore the anatomical characteristics and surgical strategies of atrioventricular septal defect (AVSD) with left ventricular outflow tract (LVOT) stenosis.MethodsThe clinical data of 11 AVSD patients with LVOT stenosis who underwent surgeries in our hospital from 2008 to 2019 were retrospectively analyzed, including 6 males and 5 females with a median age of 15.0 (7.6-22.0) years.ResultsThere were 3 patients of complete AVSD and 8 patients of partial AVSD. Subaortic stenosis resulted from discrete subaortic membrane in 3 patients, diffused subaortic membrane in 4 patients, hypertrophied muscle bundles in 3 patients and distorted valve frame in 1 patient. Among these patients, 5 patients underwent LVOT stenosis and AVSD repairs simultaneously for the first time, 5 patients underwent LVOT stenosis repair for the second time and 1 patient for the third time. No postoperative death occurred. The postoperative LVOT flow velocity decreased dramatically after LVOT stenosis repair compared with preoperative one [449.0 (393.0, 507.5) cm/s vs. 212.0 (183.0, 253.5) cm/s, P<0.05].ConclusionSurgical results of AVSD combined with LVOT stenosis are satisfactory, but the restenosis should be paid attention to via long-term follow-up.
ObjectiveTo summarize the relationship between preoperative duration of mechanical ventilation and prognosis in patients with ventricular septal defect. MethodsThe clinical data of patients with ventricular septal defect requiring ventilator support preoperatively and undergoing surgical treatment in our hospital from May 2009 to May 2020 were retrospectively reviewed. Based on the duration of preoperative ventilation, the patients were divided into three groups: a group A (0-47 hours), a group B (48-96 hours), and a group C (＞96 hours). Each group's postoperative recovery, complications, and medical costs were analyzed. Results Finally 272 patients were enrolled, including 154 males and 118 females, with a median surgical age of 2 (1, 4) months. There were 43 patients in the group A, 75 patients in the group B, and 154 patients in the group C. Early death occured in 3 (1.3%) patients, all in the group C. No statistical difference in mortality was found among the three groups (P=0.734). The mean postoperative duration of mechanical ventilation in the three groups was 158.6±133.5 hours, 101.2±56.1 hours, and 133.1±97.9 hours, respectively. The group B had significantly shorter duration than the other two groups (P＜0.05). The mean postoperative hospital stay in the three groups was 17.5±9.9 days, 13.5±5.8 days, and 16.5±10.8 days, respectively. Postoperative hospital stay in the group B was significantly shorter than that in the other two groups (P＜0.05). The mean total in-hospital cost in the three groups were 89 000±34 000 yuan, 87 000±21 000 yuan, and 109 000±41 000 yuan, respectively. The costs in the group C were significantly higher than those in the other two groups (P≤0.001). ConclusionPrompt surgical repair is necessary for patients with ventricular septal defects requiring ventilator support preoperatively. However, attention should be paid to surgical timing. Preoperative duration of mechanical ventilation is associated with better surgical outcomes within 48-96 hours than 0-47 hours or ＞96 hours.
ObjectiveTo analyze the clinical efficacy of transthoracic occlusion via a right subaxillary incision and conventional surgery in the treatment of ventricular septal defect (VSD).MethodsThe clinical data of patients with congenital VSD undergoing right subaxillary incision surgery in our hospital from January 2017 to January 2020 were retrospectively analyzed. According to the surgical methods, the patients were divided into two groups: a conventional surgery group (conventional group) and a transthoracic occlusion group (occlusion group). There were 221 patients in the conventional group, including 97 males and 124 females, with an average age of 2.6±2.2 years and an average weight of 13.4±6.2 kg; there were 185 patients in the occlusion group, including 90 males and 95 females, with an average age of 3.2±2.6 years and an average weight of 14.7±6.6 kg. The clinical effectiveness was compared.ResultsThe success rate of surgery was 100% in both groups. The intraoperative blood loss was less in the occlusion group (P<0.05). The incision length, operation time, postoperative mechanical ventilation time, retention time in the intensive care unit, the time to resume normal diet and normal activities after operation were all shorter than those in the conventional group (P all <0.05). The total cost during hospitalization of the conventional group was less than that of the occlusion group (P<0.001). There was no statistical difference in the incidence rate of perioperative complications between the two groups (P>0.05). During the follow-up (15.8±8.8 months), the incidence of complications in the conventional group was higher than that in the occlusion group with a statistical difference (P<0.001).ConclusionCompared with conventional surgery, transthoracic occlusion for VSD via right subaxillary incision has the advantages of smaller incision, shorter operation time, less blood loss, shorter postoperative recovery time and less long-term complications. However, the total hospitalization cost is relatively high, mainly because of the high consumables cost, and the long-term effects still need further comparative observation.
The patient, male, 1 year, was admitted to our hospital with cardiac murmur. Cardiac ultrasonography showed "complete atrioventricular septal defect (C-AVSD), secondary orifice atrial septal defect (ASD), patent ductus arteriosus (PDA), left superior vena cava, and pulmonary hypertension". The patient got follow-up at the age of 3, 6, 9 months and 1 year, with no feeding difficulties, no obvious underdevelopment and no history of repeated respiratory infections. Cardiac ultrasonography showed that the ventricular septal defect (VSD) healed spontaneously at 9 months of age. At 1 year of age, he was admitted to the hospital with "partial atrioventricular septal defect (P-AVSD)" and accepted surgery. Intraoperative exploration showed that the primary orifice ASD was 12 mm, the atrioventricular valve was divided into two groups, and the left atrioventricular valve had three leaflets: anterior, posterior, and lateral one. A cleft was between the anterior and posterior leaflets. The annulus was not enlarged with diameter of 13 mm. The right atrioventricular valve developed well, with fibrous hyperplasia and adhesion under the septal valve. No VSD was seen. The cleft was sutured intermittently. Autologous pericardial patch was used to repair the primary orifice ASD, and the coronary sinus was separated into the right atrium. Self-healing of VSD patients with C-AVSD is very rare, suggesting that patients with C-AVSD with normal range of development, and without obvious clinical symptoms and secondary damage, should be followed up and accept elective surgery in clinical practice.
Objective
To analyze the clinical efficacy of totally thoracoscopic surgery and conventional thoracotomy in repair of ventricular septal defect (VSD).
Methods
We retrospectively reviewed the clinical data of 50 VSD patients admitted to the First Affiliated Hospital of Xinjiang Medical University from January 2015 to January 2017. According to the surgical pattern, they were divided into two groups: a totally thoracoscopic surgery group (21 patients, 13 males, 8 females, aged 38.36±10.02 years), and a thoracotomy group (29 patients, 18 males, 11 females, aged 42.36±13.02 years). The operation time, hospital stay, ventilator-assisted time and thoracic drainage were compared between the two groups.
Results
There was no death in two groups. In the thoracoscopic group the duration of cardiopulmonary bypass (CPB) time and the aortic clamping time were longer than those of the thoracotomy group (P<0.05), but postoperative drainage, patients with postoperative use of blood products and postoperative hospital stay were less (P<0.05). There was no statistically significant difference between the two groups in operation time, postoperative ventilator-assisted time or duration of ICU stay.
Conclusion
Compared with the conventional thoracotomy, totally thoracoscopic VSD repair with less trauma, quicker recovery and less blood use, is safe and reliable and can be used as a preferred surgical intervention.
