ObjectiveTo compare the outcomes of sutureless technique and conventional technique in the surgical repair for infracardiac total anomalous pulmonary venous connection (TAPVC).MethodsThe clinical data of 46 consecutive patients with infracardiac TAPVC undergoing surgical repair in our hospital between June 2014 and April 2019 were retrospectively analyzed. Patients with combined congenital cardiac anomalies such as single ventricle and tetralogy of Fallot were excluded. Patients were divided into a conventional technique group and a sutureless technique group according to the surgical techniques. There were 35 patients in the conventional technique group, including 28 males (80.0%) and 7 females (20.0%) with a median age of 21 (8, 42) d and a median weight of 3.6 (3.0, 4.0) kg. There were 11 patients in the sutureless technique group, including 8 males (72.7%) and 3 females (27.3%) with a median age of 14 (6, 22) d and a median weight of 3.5 (2.9, 3.6) kg. The curative effect of the two groups was compared.ResultsThere were 5 deaths (10.9%) in the conventional technique group, including 4 in-hospital deaths (8.7%) and 1 late death (2.2%). Overall mortality of the conventional technique group (14.3%, 5/35) was higher than that of the sutureless technique group (0.0%, 0/11), although the difference was not statistically significant (P=0.317). Cox regression analysis showed that sex (P=0.042), age at repair (P=0.028), cardiopulmonary bypass time (P=0.007), aortic cross-clamping time (P=0.018) and duration of ventilation (P=0.042) were risk factors for postoperative mortality. The median follow-up was 18.00 (5.00, 37.75) months. Postoperative pulmonary venous obstruction occurred in 22 patients of the conventional technique group, which was significantly more than that of the sutureless technique group (P=0.000).ConclusionFor infracardiac TAPVC, sutureless technique can reduce the incidence of postoperative pulmonary venous obstruction compared with conventional technique.
Objective To analyze risk factors for pulmonary vein obstruction (PVO) after intracardiac total anomalous pulmonary venous connection (TAPVC) repair. Methods A retrospective analysis of clinical data of the patients with intracardiac TAPVC who underwent surgery at our center from April 2009 to April 2019 was conducted. Kaplan-Meier curves were used to assess the risk of postoperative PVO. Logistic regression analysis was used to identify relevant risk factor for postoperative PVO. ResultsWe finally included 169 patients. The median age at surgery was 89.0 (41.5, 195.0) days, and the median weight at surgery was 4.8 (3.8, 6.0) kg. The preoperative PVO rate was 18.3% (31/169). Post-repair PVO occurred in 8.9% (15/169) of the patients. The atresia of common pulmonary and subtype of coronary sinus/right atrium did not significantly affect the risk of PVO (P=0.053, P=0.330). Relevant risk factors included preoperative PVO (P<0.001) and the ratio of left ventricular end-systolic diameter to right ventricular diameter (P=0.025). ConclusionSurgical repair of intracardiac TAPVC has achieved satisfactory results in our center, but the long-term risk of obstruction should not be underestimated. An increased ratio of left ventricular end-systolic diameter to right ventricular diameter and preoperative PVO are associated with post-repair PVO.
ObjectiveTo compare the effect of different treatment strategies of vertical vein on the postoperative efficacy of total anomalous pulmonary venous connection (TAPVC) in newborns.MethodsThe clinical data of 72 TAPVC newborns who underwent correction in our hospital from June 2008 to January 2018 were retrospectively analyzed. There were 59 males and 13 females, with an average age of 9.93±8.13 d. According to different vertical vein treatment strategies, the patients were divided into an unligated group (22 patients), a partially ligated group (23 patients) and a completely ligated group (27 patients). The mortality and incidence of common complications among the groups were compared.ResultsIn the completely ligated group, the aortic cross-clamp time was longer (P=0.001), intraoperative circulatory arrest cases were less (P=0.005), and the early velocity of pulmonary vein was faster (P=0.029), but there was no significant difference in the velocity of pulmonary vein for the last follow-up among three groups (P=0.393). There was no significant difference in other perioperative indicators among groups, including the early mortality, the incidence of pulmonary vein obstruction and the non-closure of vertical vein after surgery (P>0.05). The mean follow-up time was 4.47±2.63 years. The follow-up mortality was not significantly different among groups (P>0.05). The cardiac function (NYHA) of all the 64 survived patients was classⅠ-Ⅱ.ConclusionProper vertical vein treatment strategies may be conducive to a smooth transition after surgery, ensuring the success of surgeries.
ObjectiveTo analyze the outcomes of surgical repair for mixed total anomalous pulmonary venous connection (TAPVC).MethodsBetween 2006 and 2018, a total of 51 patients with mixed TAPVC underwent surgery in our hospital. Patients with such associated anomalies as single ventricle and tetralogy of Fallot were excluded. There were 35 males and 16 females with a median age of 102.0 (59.0, 181.0) days and a median weight of 5.0 (4.1, 6.4) kg. Patients were divided into three categories based on the anatomy: "3+1" pattern (n=38, three pulmonary veins drained at one site, and the other drained at the opposite site); "2+2" pattern (n=9, the pulmonary veins from each lung joined to form a confluence and drained at separate sites); bizarre pattern (n=4, the anatomy could not be classified into the above two patterns).ResultsThere was no in-hospital death. The median follow-up was 41.0 (18.0, 86.5) months. Postoperative pulmonary venous obstruction occurred in 10 patients. Kaplan-Meier survival curves showed no statistically significant difference in postoperative pulmonary venous obstruction among the three groups (P=0.239). Cox risk regression showed that preoperative pulmonary venous obstruction was significantly associated with postoperative pulmonary venous obstruction (P=0.024).ConclusionMixed TAPVC has various anatomic morphologies and requires individualized surgery.
ObjectiveTo review our experience of reoperations for pulmonary venous stenosis (PVS) after total anomalous pulmonary venous connection (TAPVC) repair for the past decade in Fuwai Hospital.MethodsNine patients underwent reoperation for PVS between 2009 and 2019 in Fuwai Hospital, including 4 males and 5 females with an average age of 5.10±5.00 years. The patients were divided into a sutureless group (n=3) and a non-sutureless group (n=6). Clinical data were reviewed and analyzed.ResultsFor primary TAPVC type, 4 patients were supracardiac, 2 patients were cardiac, 1 patient was infracardiac, and 2 patients were mixed-type anomaly. The median cardiopulmonary bypass time was 95 (63, 208) min, aortic clamping time was 58 (30, 110) min, ICU stay was 24 (24, 2 136) h. Early hospital death occured in 1 (11.1%) patient. One (11.1%) patient with single ventricle physiology had hospital comorbidity, who underwent hemofitration therapy. The follow-up time was 11.9 (2.2, 18.0) months, during which 1 patient died of restenosis of pulmonary vein and another patient died of stroke. No statistically significant difference was found between the sutureless group and non-sutureless group in postoperative or follow-up results (P>0.05). ConclusionSurgery is effective for treatment of PVS after repair of TAPVC, yet with a realatively high morbidity and mortality. The advantage of sutureless repair over conventional repair for this particular group of patients is yet to be verified.
ObjectiveTo analyze clinical outcomes of sutureless technique for patients undergoing surgical correction of total anomalous pulmonary venous connection (TAPVC). MethodsBetween July 2007 and December 2013, 132 consecutive TAPVC patients underwent surgical correction in Guangdong Cardiovascular Institute. Those patients with such associated congenital cardiac anomalies as single ventricle and right atrial isomerism were excluded from this study. All the patients underwent biventricular repair. Preoperatively, all the patients received echocardiography, and most patients received CT scan to know the development of pulmonary veins. Preoperative diagnosis was confirmed by intraoperative exploration. According to different surgical techniques, all the patients were divided to a conventional technique group and a sutureless technique group. In the conventional technique group, there were 69 patients including 54 males (78.3%)and 15 females (21.7%)with their median age of 60 (30, 225)days and median body weight of 4.85 (3.50, 6.35)kg. In the sutureless technique group, there were 63 patients including 48 males (76.20%)and 15 females (23.8%)with their median age of 90 (30, 210)days and median body weight of 4.58 (3.72, 6.20)kg. Follow-up was performed till January 1, 2014. ResultsIn-hospital mortality (4.8% vs. 7.2%, χ2=1.414, P=0.720)and postoperative overall mortality (4.8% vs. 13.0%, χ2=2.733, P=0.098)of the sutureless technique group were both lower than those of the conventional technique group, although there was no statistical difference. Postoperative incidence of pulmonary venous obstruction (PVO)of the sutureless technique group was significantly lower than that of the conventional technique group (1.6% vs. 10.1%, χ2=4.236, P=0.040). Cox proportional-hazards regression showed that conventional technique and preoperative PVO were significant risk factors for postoperative PVO (P=0.023, P=0.016). Conventional technique was not significantly correlated with postoperative mortality (P=0.060). ConclusionSutureless technique can significantly lower postoperative incidence of PVO for patients with supracardiac TAPVC.
Objective To summarize the experience of the superior vena cava and pulmonary connection surgery for functional single ventricle (SV) with total anomalous pulmonary venous (TAPVC). Methods We retrospectively analyzed the clinical data of 10 patients with SV and TAPVC in our hospital from January 2012 through June 2014. There were 7 males and 3 females at average age of 90.33±86.53 months. The 10 patients were with right atrial isomerism, 9 with heterotary and asplenia syndrome. Five patients were anatomic single ventricle and others were with functional uni-ventricle. Nine patients were with supracardiac pattern TAPVC and one was with intracardiac TAPVC. All patients were operated unilateral or bilateral bidirectional Glenn procedure with TAPVC correction. Results The arterial oxygen saturation (SaO2) increased prominently after operation (86%±6% vs. 79%±6%, P<0.01). There were 3 patients with low cardiac output syndrome, one patient with severe arrhythmia, 4 patients with serious pleural effusion, 4 patients with hospital-acquired infection, and 3 patients with central nervous system complications (epilepsy or hemiplegia). One died because of hemorrhage and pulmonary thrombosis, and the other died of hypoxemia and mutiple organ dysfunction syndrome (MODS). Conclusion Glenn is one of palliated procedure choice for SV/TAPVC patients. The indication for surgery and perioperative management individually is crucial.
