ObjectiveTo share the experience of treating special cardiac malformations by applying minimally invasive techniques.MethodsEight children with special cardiac malformations admitted to our hospital from July 2014 to September 2020 were recruited, including 3 males and 5 females, aged 0.8-1.2 (1.1±0.4) years, and weighted 7.8-11.5 (9.6±2.9) kg. There were 2 patients of huge muscular ventricular septal defect (VSD), 3 perimembranous cribriform VSD, 1 right coronary-right atrial fistula, 1 right coronary-right ventricular fistula, and 1 young, low-weight child with large aortopulmonary. All were treated with minimally invasive techniques using transesophageal echocardiography (TEE) as a guiding tool. All children received intraoperative TEE immediately to evaluate the curative effect of the surgery, and all went to outpatient clinic for reexamination of echocardiography, electrocardiogram and chest X-ray after discharge.ResultsEight children underwent minimally invasive surgery successfully without any incision infection, intracardiac infection, arrhythmia or pericardial effusion. None of the 8 children were lost to follow-up, and the results of all reexaminations were satisfactory.ConclusionThe application of minimally invasive techniques is a bold and innovative attempt for the treatment of a few special types of cardiac malformations. It has significant advantages in reducing trauma and medical costs in some suitable patients, and has certain clinical reference values.
Objective To investigate the value of systemic-normothermic/cardiac-hypothermic cardiopulmonary bypass（CPB）on operation of congenital heart disease. Methods Thirty patients of congenital heart disease were randomly divided into two groups, the normothermia group（n=15）and hypothermia group（n=15）. The changes of CPB time, aortic cross-clamp time,operation time and postoperative drainage and the value of blood cell were observed. Results The duration of CPB （37. 5 ±11. 6rain vs. 51. 6± 12. 0 min, P〈0. 05） and operation time （2.2± 0.6h vs. 2. 7±0. 5h, P〈0. 01） in normothermia group were shorter than those of hypothermia group statistically, the differences of postoperative drainage and the value of blood cells between two groups were not statistically significant. Conclusion The use of systemic-normothermic/cardiac-hypothermic CPB on operation of congenital heart disease shows that the time of operation is shorter remarkly , and it could be clinically used safely.
Objective
To evaluate the effects of emergency coronary artery bypass grafting (ECABG) in the treatment of emergent patients, and to summarize our experience.
Methods
We retrospectively analyzed the clinical data of 160 patients who underwent coronary artery bypass grafting (CABG) in Nanjing General Hospital of Nanjing Command from January 2010 through December 2013. The patients were divided into an ECABG group (operation underwent on the day diagnosed, n=27, 22 males and 5 females, at age of 70.2±10.2 years) and a conventional group (CABG operation underwent on 5 days after diagnosed, n=133, 104 males and 29 females, at age of 66.3±8.9 years).
Results
Statistical differences were found between the ECABG group and the conventional group in EuroSCORE (5.8±3.2 versus 3.4±2.1, P=0.001), acute myocardial infarction (33.3% vs. 11.3%, P=0.007), rate of application of IABP (29.6% versus 12.0%, P=0.034), pericardium and mediastinal tube drainage (533.4±132.8 ml versus 414.8±124.3 ml, P=0.018). There was no statistical difference in continuous renal replacement therapy (P=0.677), postoperative sternal wound complication (P=1.000), the length of hospital stay (P=0.589), or 30-day-mortality (P=0.198) between the two groups. We followed up 24 patients(88.89%) for 3-36 months in the ECABG group. One patient occurred angina symptoms at the end of 1 year follow-up. The symptoms disappeared after treatment. The other patients had no symptoms of angina pectoris and myocardial ischemia.
Conclusion
ECABG as a lifesaving therapy is an effective procedure in the treatment of severe and acute patients. Sufficient preoperative assessment, good myocardial protection, full revascularization, and comprehensive treatment plays an important role in the success of ECABG.
Objective To evaluate the clinical efficacy of coronary artery bypass grafting in the treatment of coronary artery disease patients aged over 70 years. Methods A total of 160 patients with coronary atherosclerotic heart disease underwent off-pump coronary artery bypass grafting from January 2013 to December 2017. There were 94 males and 66 females at age of 70–85 (76.67±2.33) years. Operations were performed by using sternal median incision with the assistance of local myocardial surface fixator and shunt plug, and the saphenous vein and internal mammary arterywere used as grafted vessels. Results All the patients were received successful off-pump coronary artery bypass grafting without death, and the cardiac function improved significantly. There were 62 patients with the internal mammary artery bridge and 98 patients with the whole vein bridge. All the patients were followed-up for 1 to 4 years. All the patients had obvious relief of angina pectoris. Conclusion Off-pump coronary artery bypass grafting for the treatment of elderly patients with coronary heart disease is an effective and safe operation, especially for patients with renal insufficiency, cerebrovascular disease, respiratory disease and severe left ventricular dysfunction.
Objective
To explore the feasibility of transcatheter closure of congenital heart disease (CHD) under the guidance of transthoracic echocardiography (TTE).
Methods
A total of 37 patients with CHD who received transcatheter closure under the guidance of transthoracic echocardiography from November 2013 through November 2015 in our hospital were recruited. There were 15 males and 22 females, aged 1 to 16 years. Among them 32 patients suffered atrial septal defect and 5 patients had patent ductus arteriosus. The transcatheter closure of CHD was performed under the guidance of TTE. The patients underwent echocardiography follow-up at one, three and six months after surgery.
Results
Closure devices were successfully implanted in 37 patients under TTE guidance. The procedure was simple and safe. During the follow-up, no severe complication such as valvular injury, pericardial effusion, residual shunt and peripheral vascular injury occurred.
Conclusion
Transcatheter closure of CHD under TTE guidance is a feasible method and worth further clinical application.

Methods : 86 patients of either sex (ASA status ⅢⅣ; New York Heart Association classes ⅡⅢ) scheduled for valve replacement surgery were included in this randomized clinical trial (RCT). SwanGanz catheter was placed via right internal jugular vein before the induction of anaesthesia. Anaesthesia was induced with midazolam 00501mg.kg-1 and fentanyl 1015 μg·kg-1. The patients were randomized to receive either rocuronium 06 mg·kg-1 (group R, 〖WTBX〗n= 42) or vecuronium 01 mg·kg-1 (group V, 〖WTBX〗n= 41) to facilitate tracheal intubation when bispectral index (BIS) value dropped to 60 All data were recorded at the time before anaesthesia (Tb), loss of consciousness (Ts), administration of muscle relaxant (Tm), 1 min after administration of muscle relaxant (T1), when trainoffour stimulation (TOF) reached 0 (T2) and 1,2,3,4,5,7,10 min after tracheal intubation (T39).〖WTHZ〗Results : Heart rate (HR) increased by 174%135%, systemic arterial systolic pressure (SAP) increased by 1694%143%, mean arterial systolic pressure (MAP) increased by 151%132% and product of heart rate and arterial systolic pressure(RPP) increased 2267%1396% respectively during 5 minutes after intubation as compared with baseline in group R, which were significantly higher than those in group V during 5 minutes after intubation (〖WTBX〗P lt;005). Conclusion : An intubation dose of rocuronium should be used cautiously in patients with rheumatic heart disease (ASA status ⅢⅣ; NYHA classes IIⅢ).
ObjectiveTo summarize the individualized selection of surgical treatment strategies and the key points of perioperative management for patients with heart valve disease complicated with severe chronic heart failure.MethodsThe clinical characteristics of 5 male patients with valvular heart disease complicated with severe chronic heart failure (CHF) were analyzed retrospectively from June 2017 to October 2018 in Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, with an average age of 60.21 years.ResultsFive patients were given angiotensin receptor and neprilysin inhibitor (ARNI)-based anti-heart failure treatment after admission. The operation mode of these patients was decided to be valve replacement under cardiopulmonary bypass after individualized evaluation of patients’ improving symptoms. Three patients were treated with intra-aortic balloon pump (IABP) and continuous renal replacement therapy (CRRT) early after operation to assist patients in improving cardiac function. Five patients recovered oral anti-heart failure after awakening. All patients were discharged smoothly 2 weeks after operation.ConclusionIndividualized evaluation is needed for the choice of operation timing and mode, standardized preoperative treatment for heart failure, shortening the aortic blocking time during cardiopulmonary bypass, and early application of left ventricular adjuvant drugs or instruments are all important measures to help patients recover smoothly.
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.
Objective To summarize the clinical outcome and strategy of re-operation on adult and older children patients with congenital heart disease.
Methods We retrospectively analyzed the clinical data of 339 patients underwent re-operation in our hospital from January 2010 to December 2014. There were 214 males and 125 females at the mean age of 21.6±12.4 years. According to the pathophysiological result and the difficulty level of operation, patients were divided into a simple re-operation group (n=186) and a complex re-operation group (n=153) . We compared the clinical outcomes of two groups.
Results In the simple re-operation group, the rate of mortality was zero and the rate of complications was 5.9%. There was 1 patient of interoperative right atrium injury, 1 patient of extensive hemorrhage, 5 patients of postoperative secondary thoracotomy, 1 patient of hemodialysis, 3 patients of severe infection, and 2 patients of Ⅲ degree atrioventricular blockage. In the complex re-operation group, the rate of mortality was 3.3% and the rate of complication was 30.1%. There were 2 patients of intraoperative coronary artery lesion, 2 patients of aortic injury, 1 patient of pulmonary artery injury, 6 patients of extensive bleeding, 8 patients of postoperative secondary thoracotomy, 13 patients of hemodialysis, 12 patients of severe infection, 5 patients of nervous system complications, 4 patients of Ⅲ degree atrioventricular blockage. Extracorporeal membrane oxygenation (ECMO) applied in 4 patients.
Conciusion Complex re-operation is still the influential factor of mortality and complications for patients with congenital heart disease and we should take measures to aviod the mortality and complications.
This review provides an overview of prenatal interventional treatments for fetal congenital heart disease (CHD), with a particular focus on the latest advancements in fetal aortic valvuloplasty (FAV) and fetal pulmonary valvuloplasty (FPV). FAV aims to improve left heart hemodynamics, prevent hypoplastic left heart syndrome (HLHS), and promote biventricular circulation. FPV seeks to improve the natural history of pulmonary atresia with intact ventricular septum (PA/IVS) and critical pulmonary stenosis with intact ventricular septum (CPS/IVS), alleviate right ventricular outflow tract obstruction, and promote biventricular circulation. This article discusses patient selection, technical details, risk assessment, and clinical outcomes for these procedures, highlighting the challenges in current research, including the lack of standardized patient selection criteria and long-term prognostic studies. Additionally, it emphasizes the opportunities and challenges of fetal cardiac intervention (FCI) development in China and proposes recommendations for future improvements and research directions.
