Objective To examine the influence of hormonal fluctuations on the perioperative outcomes of patients undergoing congenital heart surgery. Methods We conducted a retrospective analysis of clinical data from fertile women diagnosed with congenital heart disease at the Guangdong Provincial People's Hospital, between January 1, 2015, and July 30, 2019. Initially, patients were categorized into groups based on serum progesterone levels: a low progesterone group (n=31) and a high progesterone group (n=153). Furthermore, based on serum estrogen levels, they were divided into a low estrogen group (n=10), a medium estrogen group (n=32), and a high estrogen group (n=118) for comparative analysis. A control group (n=24) consisted of patients who received progesterone injections before their menstrual period. Results We finally included 184 patients. The patients’ average age was 27.6±5.7 years, with 142 (77.17%) presenting with complex congenital heart conditions. There were statistically significant differences in total postoperative standard thoracic drainage volume and postoperative albumin level between the high and low progesterone groups (P<0.05), while other perioperative outcome indicators showed no statistical differences (P>0.05). Among the different serum estrogen level groups, there were statistically significant differences in postoperative blood urea nitrogen levels, total postoperative standard thoracic drainage volume, and hospital stay (P<0.05), while other perioperative outcome indicators showed no statistical differences (P>0.05). ConclusionConsidering the overall clinical significance, the physiological changes in sex hormone levels appear to have a negligible effect on the perioperative outcomes of fertile women with congenital heart disease.
ObjectiveTo compare the benefits and drawbacks of primary patch expansion and pericardial tube right ventricular-pulmonary artery connection in patients diagnosed with pulmonary atresia with ventricular septal defect (PA/VSD). MethodsA retrospective study was conducted on the patients who were diagnosed with pulmonary atresia with ventricular septal defect (PA/VSD) and underwent primary right ventricular-pulmonary artery connection surgery at our center between January 2010 and December 2020. The patients were categorized into two groups based on the type of right ventricular-pulmonary artery connection: the whole pericardial tube right ventricular-pulmonary artery connection group (pericardial tube group), and the patch expansion right ventricular-pulmonary artery connection group (patch expansion group). The patients' general clinical data and cardiopulmonary bypass data were documented, and the cardiac CT data obtained before and after the surgery were compared with the clinical and imaging data. ResultsFinally 51 patients were collected, including 31 males and 20 females, with a median age of 12.57 (4.57, 49.67) months. There were 19 patients in the pericardial tube group, with a median age of 17.17 (7.33, 49.67) months, and 32 patients in the patch expansion group with a median age of 8.58 (3.57, 52.72) months. In both groups, the diameter, McGoon index, and Nakata index were significantly increased after treatment (P<0.001). However, the pericardial tube group required a longer occlusion time (P<0.001). The rate of reoperation was high, with 72.5% of patients requiring further surgery. Specifically, 26 (81.3%) patients in the patch expansion group and 12 (63.2%) patients in the pericardial tube group finally completed radical resection. There was no statistical difference observed in the long-term cure rate or mortality between the two groups. Conclusion In patients with PA/VSD, the use of patch expansion or pericardial tube right ventricular-pulmonary artery connection as the initial palliative treatment strategy can promote the development of pulmonary vessels and provide a favorable basis for subsequent radical operations. However, compared to pericardial tube, patch expanded right ventricular-pulmonary artery connection is a simpler procedure to perform and retains some of the intrinsic pulmonary artery development potential, thus making it a preferred procedure.
Objective To modify the sewing technique of a hand-made bicuspid pulmonary valve using the expanded polytetrafluoroethylene in right ventricle outflow tract reconstruction for summarizing the short-term experience. Methods The patients with complex congenital heart diseases and concurrent contaminant pulmonary regurgitation that underwent right ventricle outflow tract reconstruction through the bicuspid pulmonary valve were enrolled. The postoperative artificial valve function and right ventricle function indexes were evaluated. Results A total of 17 patients were collected, including 10 males and 7 females, with an average age of 18.18 years and an average weight of 40.94 kg. Of 17 patients, 16 used valved conduit for the reconstruction of the right ventricle outflow tract with the size ranging from 18 to 24 mm. There was no patient requiring mechanical circulatory support and no in-hospital death. During the follow-up with a mean period of 12.89 months, only one vale dysfunction occurred without any complications and adverse events (P<0.001). Postoperative right atrium diameter, right ventricle diameter, and tricuspid regurgitation area significantly decreased in contrast to those preoperatively (P<0.05). Conclusion Sewing the bicuspid pulmonary valve utilizing 0.1 mm expanded polytetrafluoroethylene is a feasible, effective, and safe technique of right ventricle outflow tract reconstruction in the field of complex congenital heart diseases.
Atrial fibrillation is a common clinical arrhythmia with a high incidence. The main clinical treatment methods for atrial fibrillation at present include radiofrequency catheter ablation and cryoablation. In recent years, pulsed field ablation, a new energy source with tissue specificity, is gradually being used in clinical practice. This article presents the world's first case of atrial fibrillation treated with pulsed field surgical ablation, in which the patient underwent surgical intervention of the valves and coronary arteries at the same time and recovered to sinus rhythm intraoperatively. 24 hour-Holter electrocardiogram after 1 month and 3 months showed no atrial fibrillation. The patient’s symptoms, cardiac function, and quality of life improved significantly.
Objective To comprehensively analyze the clinical outcomes of total cavopulmonary connection (TCPC) in the treatment of functional single ventricle combined with heterotaxy syndrome (HS). MethodsA retrospective analysis was conducted on the patients with functional single ventricle and HS who underwent TCPC (a HS group) in Guangdong Provincial People's Hospital between 2004 and 2021. The analysis focused on postoperative complications, long-term survival rates, and identifying factors associated with patient survival. Early and late postoperative outcomes were compared with matched non-HS patients (a non-HS group). Results Before propensity score matching, 55 patients were collected in the HS group, including 42 males and 13 females, with a median age of 6.0 (4.2, 11.8) years and a median weight of 17.0 (14.2, 28.8) kg. Among the patients, there were 53 patients of right atrial isomerism and 2 patients of left atrial isomerism. Eight patients underwent TCPC in one stage. TCPC procedures included extracardiac conduit (n=39), intracardiac-extracardiac conduit (n=14), and direct cavopulmonary connection (n=2). Postoperative complications included infections in 27 patients, liver function damage in 19 patients, and acute kidney injury in 11 patients. There were 5 early deaths. The median follow-up time was 94.7 (64.3, 129.8) months. The 1-year, 5-year, and 10-year survival rates were 87.2%, 85.3%, and 74.3%, respectively. After propensity score matching, there were 45 patients in the HS group and 81 patients in the non-HS group. Compared to the non-HS group, those with HS had longer surgical and mechanical ventilation time, higher infection rates (P<0.05), and a 12.9% lower 10-year survival rate. Multivariate Cox regression analysis identified asplenia was a risk factor for mortality (HR=8.98, 95%CI 1.86-43.34, P=0.006). ConclusionCompared to non-HS patients, patients with HS have lower survival rates after TCPC, and asplenia is an independent risk factor for the survival of these patients.
