  • Right vertical infra-axillary thoracotomy in surgical repair for intra-cardiac congenital heart defects combined with patent ductus arteriosus

    ObjectiveTo investigate effectiveness and safety of right vertical infra-axillary thoracotomy (RVIAT) in surgical repair for intra-cardiac anomalies combined with patent ductus arteriosus (PDA).MethodsWe retrospectively analyzed the clinical data of 34 patients who underwent intra-cardiac correction of congenital heart defects and PDA ligation simultaneously via RVIAT in our hospital from August 2014 to August 2019. There were 25 males and 9 females with an age range of 0.5-6.1 years.ResultsThe length of incision was 3.0 (3.0, 3.5) cm. The operation time lasted 110.0 (90.0, 121.0) min. The cardiopulmonary bypass time was 45.5 (38.8, 63.5) min and the aortic cross-clamp time was 22.5 (14.8, 34.8) min. The bleeding volume was 20.0 (13.8, 20.0) mL. ICU stay time was 17.0 (5.5, 22.3) h, post-operative mechanical ventilation time was 4.0 (2.0, 6.0) h, total in-hospital cost was 46 (39, 51) thousand yuan. There was no mortality or reoperation during perioperative and follow-up period. Within the median follow-up of 636.0 days, 1 patient had minimal residual ventricular septal defect shunt while no new-onset scoliosis, funnel chest or pectus carinatum was detected. No bilateral mammary developmental asymmetry was observed in the female patients during the follow-up period. All the patients’ parents or guardians were satisfied with the right vertical infra-axillary aesthetic skin incision.ConclusionThe minimally invasive repair for intra-cardiac heart defects combined with PDA via RVIAT is a safe and effective method with minimal invasiveness and excellent cosmesis.

  • Chinese expert consensus on surgical treatment of congenital heart disease (8): Series of procedures for univentricular heart

    In patients with a functionally univentricular heart, the Fontan strategy achieves separation of the systemic and pulmonary circulation and reduction of ventricular volume overload. Contemporary modifications of surgical techniques have significantly improved survival rate. However, the resulting Fontan physiology is associated with high morbidity. Despite large improvements in outcomes of contemporary Fontan patients, a large burden of disease exists in this patient population. In face of the imbalance of medical resources in China and different understanding of Fontan treatment in various regions, there is no consensus on the current status of Fontan strategy, surgical technique and perioperative treatment. By reviewing large amounts of literature, assessing survival rate and risk factors for mortality and complications of the Fontan circulation, knowledge sharing from tens of experts, we achieved a consensus on many aspects of palliation of Fontan. We hope this consensus will help Chinese colleagues further continue their efforts to improve surgical outcomes of the univentricular heart patients.

  • Transthoracic Balloon Valvuloplasty for Severe and Critical Pulmonary Valve Stenosis in Infants below One Year

    Abstract: Objective To summarize the immediate effects and the near and midterm followup results of transthoracic balloon valvuloplasty for newborns and infants with severe and critical pulmonary valve stenosis to find out an effective plan for onestop balloon valvuloplasty. Methods From March 2006 to March 2010, 32 patients including 23 males and 9 females with severe and critical pulmonary valve stenosis were treated in Fu Wai Hospital. Their age ranged from 5 days to 11 months (4.59±3.21 months). Weight of the patients ranged from 2.3 to 10.5 kg (6.48±2.05 kg). Dilatation was performed under general anesthesia with intubation and the guidance of echocardiography. During the follow-up period, all survivors had serial echocardiographic assessment to measure the transpulmonary pressure gradient (TPG) and the degree of pulmonary regurgitation. Results All operations were successful with no severe postoperative complications. Hemodynamic indexes were stable after operation with TPG lowered from from 82±27 mm Hg preoperatively to 23±12 mm Hg postoperatively (t=15.28, Plt;0.05). Only 4 patients had a TPG of more than 40 mm Hg on echocardiography before leaving the hospital. Tricuspid regurgitation was decreased significantly with 17 cases of nonregurgitation, 13 cases of light regurgitation and 2 cases of moderate regurgitation. Saturation of peripheral oxygen in all the patients increased to higher than 95%. Followup time ranged from 1 month to 4 years (16±11 months). The results of the follow-up were satisfying for all the patients. The average TPG was 17±10 mm Hg with only one above 40 mm Hg. Pulmonary valve regurgitation was found in 24 patients including 23 with light pulmonary regurgitation and 1 with moderate regurgitation. Conclusion Transthoracic balloon valvuloplasty for newborns and infants with severe and critical pulmonary valve stenosis is safe and effective.

    ObjectiveTo summarize the treatment results of double aortic arch (DAA) by minimally invasive surgical technique. MethodsWe retrospectively analyzed the clinical data of DAA patients who underwent minimally invasive surgeries in our center between October 2016 and August 2021. ResultsThere were 11 males and 4 females with a mean age of 3-61 (20.00±18.80) years. There were 8 patients of DAA and 7 patients of DAA complicated with distal left-sided aortic arch atresia and ligamentum connection. All patients received operations through minimal subaxillary incision, 13 patients were through left side and 2 patients were through right side. One patient with ventricular septal defect was performed operations concurrently under the cardiopulmonary bypass through right minimal subaxillary incision. All patients had symptom improvement without surgery related complications or death in postoperative period. The duration of operation was 30-192 (61.93±40.19) min and mechanical ventilation time was 2-9 (5.33±2.53) h. The length of ICU stay was 18-124 (51.00±38.07) h and hospital stay time was 8-21 (12.67±3.42) d. All patients had symptomatic relief with good growth and exercise tolerance during the follow-up of 6 (3, 9) months. ConclusionMinimally invasive surgical technique is a safe, effective and cosmetic approach with good results for DAA treatment.

  • Clinical outcome of tricuspid valve replacement in children aged no more than 14 years

    ObjectiveTo summarize the clinical characteristics and outcome of tricuspid valve replacement (TVR) in children aged no more than 14 years, and to discuss the selection of prosthesis.MethodsFrom September 2002 to August 2019, 14 patients aged no more than 14 years who received TVR were included in our study. There were 9 males and 5 females, with a mean age of 9.8±4.3 years.ResultsMechanical prosthesis was implanted in 8 patients, and bioprosthesis in 6 patients. The mean cardiopulmonary time and aortic-clamp time was 170.3±109.8 min and 95.1±63.1 min, respectively. The mortality within 30 days after surgery was 21.4% (3/14), and all 3 patients died of severe low cardiac output syndrome. Eleven patients were followed up for 34-199 (100.1±57.4) months. During the follow-up, mechanical prosthesis dysfunction occurred in 3 patients, 2 of whom received secondary TVR. One patient died during the follow-up.ConclusionThe bioprosthesis is the first choice for TVR in children. Some long-term complications may occur after TVR, and close follow-up and timely intervention are needed.

  • Clinical analysis of unroofed coronary sinus syndrome with endocardial cushion defect

    Objective To analyze pathologic features and surgical procedures for patients with unroofed coronary sinus syndrome (UCSS) associated with endocardial cushion defect (ECD). Methods The clinical data of 44 patients with UCSS and ECD from May 1998 to July 2016 were retrospectively reviewed. There were 18 males and 26 females with a mean age of 10.4±12.1 years (range: 5.0 months to 44.0 years) and mean weight of 25.2±20.9 kg (range 5.2-80.0 kg). According to the Kirklin and Barratt-Boyes classification, 28 patients were categorized into type Ⅰ, 5 typeⅡ , 4 type Ⅲ and 7 type Ⅳ. Among them 25 patients suffered partial ECD, 10 complete ECD, 9 transitional ECD, and 27 were associated with single atrium, 34 involved persistent left superior vena cava (PLSVC), and in 27 of the 34 patients PLSVC directly drained into the left atrium (LA). Among the 44 patients, 1 patient associated with complex anomalies underwent palliative operation, and other cardiac malformations were corrected simultaneously by surgical correction. PLSVC was ligated in 2 patients, and the intracardiac tunnels or baffles to drain PLSVC to right atrium (RA) were reconstructed in 25 patients. The associated cardiac lesions were corrected concomitantly. Results In-hospital death occurred in 2 patients, among whom 1 died of low cardiac output syndrome on postoperative day 8 and the other pulmonary infection on postoperative day 21. Thirty-one were followed up from 1 month to 10 years, and there was no death or severe complications. Conclusion When ECD is associated with PLSVC and a single atrium, UCSS may develop. Repair according to the type of UCSS is effective.

  • Mid- and long-term results of different techniques for subaortic stenosis

    ObjectiveTo evaluate the mid- and long-term outcomes of different surgical techniques for subaortic stenosis.MethodsThe clinical data of 75 patients with subaortic stenosis who underwent surgery in our hospital from January 2008 to January 2018 were retrospectively analyzed, including 48 males and 27 females, with a median age of 72 (48, 132) months and mean weight of 21.35±15.82 kg. There were 40 (53.3%) patients combined with aortic regurgitation; 38 (50.7%) patients were the first time and 37 patients were the second time to receive the operation. According to the surgical techniques, 75 patients were divided into two groups: a group A (40 patients with simple subaortic membrane resection) and a group B (35 patients with subaortic membrane and muscle resection or modified Konno procedure).ResultsTwo (2.67%) patients died in hospital. There was one late death in the group B. The average preoperative and postoperative pressure gradient of all patients was 69.96±42.02 mm Hg and 7.44±12.45 mm Hg, respectively. All patients were followed up for 51 (12, 120) months. Pressure gradient at follow-up in the group A and the group B was 8.83±14.52 mm Hg and 5.86±9.53 mm Hg, respectively with no statistical difference (P=0.294). Four patients in the group A and 2 patients in the group B needed reintervention. However, there was no statistical difference in the long-term reintervention rate between the two groups (P=0.480).ConclusionFor the different degree of lesions in the left ventricular outflow tract, our management strategy is feasible. Although there is no statistical difference between two the groups in the long-term reintervention rate after simple valvular membrane resection, prolonged follow-up is necessary to examine the long-term outcomes of different surgical techniques.

  • Treatment of supracardiac total anomalous pulmonary venous connection in a single center

    ObjectiveTo analyze the surgical results of patients with supracardiac total anomalous pulmonary venous connection (TAPVC) in a single pediatric cardiac center.MethodsA retrospective study was conducted on 98 pediatric patients with supracardiac TAPVC receiving surgical repair from 2014 to 2019 in our center. There were 64 males and 34 females with a median surgical age of 3.0 (1.5, 7.0) months and a median weight of 5.0 (4.0, 6.0) kg. Twenty-three (23.5%) patients had preoperative pulmonary vein obstruction. Ninety-two (93.9%) patients received conventional surgical repair, while six (6.1%) patients were treated with the sutureless technique. The Cox regression model was used to analyze the data.ResultsThe median follow-up time was 26.50 (5.75, 44.25) months. There were 9 (9.2%) deaths. Lower weight at the time of repair (P=0.013) and prolonged cardiopulmonary bypass time (P=0.007) were associated with mortality. Postoperative pulmonary vein obstruction was observed in 8 (8.2%) patients. Associated risk factors for postoperative pulmonary vein obstruction included lower weight at the time of repair (P=0.042) and prolonged cardiopulmonary bypass time (P=0.002).ConclusionSurgical repair of supracardiac TAPVC has achieved satisfactory results in our center. Risk factors such as lower weight at the time of repair and prolonged cardiopulmonary bypass time are associated with a poor prognosis.

  • The long-term durability of valved homograft conduit in right ventricular outflow tract reconstruction after Ross surgery and non-Ross surgery

    ObjectiveTo compare the long-term durability of valved homograft conduit (VHC) in patients with Ross and non-Ross right ventricular outflow tract (RVOT) reconstruction. MethodsPatients who underwent RVOT reconstruction using VHC in Fuwai Hospital from January 2008 to October 2020 were retrospectively included. Patients who received Ross RVOT reconstruction were allocated to a Ross group and patients who received non-Ross RVOT reconstruction were allocated to a non-Ross group. The survival and reintervention-free rates of the two groups were evaluated with the Kaplan-Meier survival curve and log-rank test. The propensity score matching analysis was performed on the patients who completed ultrasound follow-up in the two groups, and the VHC dysfunction-free rate was compared between the two groups. ResultsA total of 243 patients were enrolled, including 142 males and 101 females, with a median age of 6 years (4 months to 56 years). There were 77 patients in the ROSS group and 166 patients (168 operations) in the non-ROSS group. The cardiopulmonary bypass time in the Ross group was shorter than that in the non-Ross group (175.4±45.6 min vs. 200.1±83.5 min, P=0.003). Five patients in the non-Ross group died early after the operation. The follow-up was available in 231 patients (93.1%), with the average follow-up time of 61.7±44.4 months. During the follow-up, 5 patients in the non-Ross group died. The 12-year survival rate was 100.0% in the Ross group and 93.2% in the non-Ross group (log-rank, P=0.026). In addition, 1 patient in the Ross group and 7 patients in the non-Ross group received VHC reintervention. There was no significant difference in the reintervention-free rate between the two groups (log-rank, P=0.096). Among the 73 patients in the Ross group and 147 patients in non-Ross group who were followed up by ultrasound after discharge, 45 patients (20.5%) developed VHC dysfunction. Before matching, the long-term durability of VHC in the Ross group was better than that in non-Ross group (10-year VHC dysfunction-free rate: 66.6% vs. 37.1%, log-rank, P=0.025). After the propensity score matching, 64 patients included in each group, and there was no statistical difference in the long-term durability of VHC between the two groups (10-year VHC dysfunction-free rate: 76.3% vs. 43.0%, log-rank, P=0.065). In the subgroup analysis, the 10-year VHC dysfunction-free rate in the Ross group was higher than that in the non-Ross group (71.0% vs. 20.0%, log-rank, P=0.032) among patients aged<6 years at surgery. However, there was no significant difference in the 10-year VHC dysfunction-free rate between the two groups (53.7% vs. 56.7%, log-rank, P=0.218) among patients aged ≥6 years at surgery. ConclusionAfter the propensity score matching analysis, the long-term durability of VHC has no significant difference between the Ross group and non-Ross group. The long-term durability of VHC after Ross surgery is superior to that of non-Ross surgery in patients aged<6 years at surgery.

  • Application status of right ventricular outflow tract reconstruction with valved homograft conduits: 13 years’ clinical analysis of a single center

    ObjectiveTo evaluate the clinical outcome of valved homograft conduits (VHC) used for right ventricular outflow tract (RVOT) reconstruction in Fuwai Hospital in recent 13 years, and explore the factors influencing the long-term durability of VHC. MethodsClinical data of patients using VHC for RVOT reconstruction in Fuwai Hospital from November 2007 to October 2020 were retrospectively analyzed. The Kaplan-Meier survival curve was used to evaluate survival, VHC reintervention and VHC dysfunction. Cox proportional risk regression model was used to analyze the risk factors for VHC dysfunction. ResultsFinally 251 patients were enrolled, including 145 males and 106 females. The median age at surgery was 6.0 (0.3-67.0) years. Early death occurred in 5 (2.0%) patients. The follow-up was available for 239 (95.2%) patients, with the follow-up time of 0.3-160.0 (61.3±45.4) months. Five patients died during the follow-up, and the 1-year, 6-year, and 13-year survival rates were 96.6%, 95.5% and 95.5%, respectively. Eight patients received VHC reintervention during the follow-up, and freedom rates from VHC reintervention were 100.0%, 97.1% and 82.4% at 1 year, 6 years and 13 years, respectively. A total of 226 patients were followed up by echocardiography after discharge, with the follow-up time of 0.2-138.0 (48.5±40.5) months. During the follow-up, 46 (20.4%) patients developed VHC dysfunction, and freedom rates from VHC dysfunction at 1 year, 5 years, and 10 years were 92.6%, 79.6% and 59.3%, respectively. Univariate Cox regression analysis showed that age<6 years and VHC diameter<19 mm were risk factors for VHC dysfunction (P=0.029, 0.026), but multivariate regression analysis only indicated that age<6 years was an independent risk factor for VHC dysfunction (P=0.034). ConclusionThe early and late outcomes of VHC used for RVOT reconstruction are satisfactory, and the long-term durability of VHC is also optimal. In addition, age<6 years is an independent risk factor for VHC dysfunction.
