Methods: Twentyfive cases underwent surgical repair after failure of perventricular closure of VSD were included in this study. With combination of echocardiographic and surgical findings, retrospective analysis of the failure of perventricular closure of VSD were attempted to summarize the cause of complications.Results: Residual ventricular communication was due to underestimation of size of VSD and pseudomembranous aneurysm resulting in multiple outlets of VSD on the right ventricle side; preoperative prolapse of rightcoronary cusp was the main reason for mild or greater than mild aortic valve regurgitation after eccentric device closure of VSD; Underestimation of the size of VSD and using eccentric occluder device were responsible for the displacement of VSD occluder device. Postoperative aggravated tricuspid regurgitation and Ⅲ°atrialventricular block (AVB) were attributed to VSDs located under the septal leaflet of tricuspid valve. The size of VSD in group of failed perventricular device closure of VSD was larger than that in group of successful device closure of VSD,and the difference was significant(Plt;0.05). Conclusion: Echocardiography vividly reveals VSD and adjacent structures, which should be used in accessing the anomaly and defect and formulating surgical plans to reduce surgical morbidity and mortality.
Objective To assess the efficacy and safety of percutaneous closure of patent ductus arteriosus (PDA) solely under echocardiography guidance. Methods We retrospectively analyzed the clinical data of 200 patients who received the percutaneous closure of PDA under echocardiography guidance in Fuwai Hospital from August 2013 to April 2016. According the different approach, they were divided into 2 groups: a femoral artery approach group (n=143) and a femoral vein approach group (n=57). In the femoral artery approach group, there were 42 males and 101 females aged 3.20±5.63 years. In the femoral vein group, there were 10 males and 47 females aged 7.30±11.36 years. All Patients were treated by percutaneous PDA closure solely under echocardiography guidance. The follow-up was performed at one month after the operation by echocardiography, chest radiograph and electrocardiogram. Results All 200 patients were successfully treated with percutaneous closure of PDA. The patients’ gender, in-hospital stay, rates of occluder detachment were similar between the two groups (P>0.05). Compared with the femoral vein approach group, the femoral artery approach group had a younger age (3.20±5.63 yearsvs. 7.30±11.36 years, P<0.001), less body weight (14.25±11.54 kgvs. 24.25±19.14 kg, P<0.001) and shorter diameter of PDA (3.06±0.79 mmvs. 5.93±0.68 mm, P<0.001) and PDA occluders (5.43±1.00 mmvs. 12.14±0.54 mm, P<0.001), but had higher hospitalization expenses (32 108.2±3 100.2 yuanvs.25 120.7±3 534.1 yuan, P<0.001). In the femoral vein approach group, one patient was closed under radiation guidance because guide wires could not pass through PDA. One patient in the femoral artery approach group suffered from occluder detachment at one day after operation and was cured by transthoracic minimally invasive PDA occlusion. There were no complications of occluder detachment, residual shunt, pericardial effusion or left pulmonary stenosis during the follow-up. Conclusion Echocardiography-guided percutaneous PDA closure is safe and effective, while the proper interventional approach should be chosen by the anatomical features of PDA.
In recent years, transcatheter mitral valve replacement is a focused issue in the field of valve intervention, which brings hope to mitral regurgitation patients who are not suitable for surgical thoracotomy. This paper presents the case of echocardiography-guided transseptal mitral valve replacement with the HighLife system in an elderly female patient with severe mitral regurgitation who failed to respond to standard medical therapy. During the procedure, echocardiography was used to guide the wire looping, cinching, atrial septal puncture, ring closure, atrial septal balloon dilatation, prosthetic valve implantation and immediate postoperative evaluation. Echocardiography plays an important role in transseptal mitral valve replacement, which can help the procedural process and improve the safety of the procedure.
Objective To explore the dominant views with positive results when performing echocardiography on common congenital heart diseases (CHD) in children using the "Seven-Step Screening Method for Pediatric Echocardiography". MethodsThe echocardiographic data of children with atrial septal defect, patent foramen ovale, ventricular septal defect, and patent ductus arteriosus were collected from September 2021 to February 2022. The disease type distribution, view distribution, and the dominant view distribution were analyzed. Dominant view refered to the view with a high ratio of positive result images per view to the total image in each disease. Results A total of 8 353 images of 1 633 children with common CHD were collected. There were 813 males and 820 females at age of 0-7 years. Including 3 613 images in 701 patients with atrial septal defect, 1 178 images in 206 patients with patent foramen ovale, 2 857 images in 576 patients with ventricular septal defect, and 705 images in 150 patients with patent ductus arteriosus. The dominant views of atrial septal defect were subxiphoid 2-chamber view (92.96%), subxiphoid 4-chamber view (85.61%), parasternal 4-chamber view (62.07%), and parasternal short-axis view (38.50%). The dominant views of patent foramen ovale were subxiphoid 2-chamber view (82.69%) and subxiphoid 4-chamber view (65.41%). The dominant views of ventricular septal defect were parasternal 5-chamber view (79.73%), parasternal short-axis view (79.41%), parasternal 4-chamber view (58.18%), and parasternal long-axis view (51.11%). The dominant view of patent ductus arteriosus were parasternal short-axis view (98.80%). Conclusions The analysis of the lesion key areas of common CHD showed that there were 4 dominant views for atrial septal defect and ventricular septal defect, 2 for patent foramen ovale, and only 1 for patent ductus arteriosus. Clarifying the dominant views of common CHD were conducive to rapid and accurate diagnosis of diseases, clinical, teaching and scientific research.
Abstract: Objective To introduce a new technique: transthoracic closure of perimembranous ventricular septal defect (VSD) without cardiopulmonary bypass (CPB) under transesophageal echocardiography (TEE）guidance, and summarize the clinical experiences and midterm followup results. Methods A total of 136 patients with perimembranous VSD, 3 months to 15 years averaging 1.8 years, underwent transthoracic device closure. The weight of these patients ranged from 4.0 to 26.0 kg with an average weight of 12.7 kg. The diameter of their VSD ranged from 3 to 12 mm averaging 5.1 mm. A small transthoracic incision (34 cm incision by inferior sternotomy or 23 cm transverse incision in the third intercostal space) was made and the best location for right ventricular puncture was chosen and the delivery pathway was established under TEE guidance. Proper devices were delivered and then deployed to close the defect. Patients were followed up closely with a standard protocol, arranged for echocardiography, electrocardiogram and chest Xray film. Results In all the cases, 131 cases of VSD (96.3%) were successfully closed. The procedure time was less than 90 minutes and the implanting time was 5.42 minutes (16.3±5.7 min). Symmetrical devices were implanted into 89(67.9%) of the 131 patients and the other 42 patients (32.1%) were closed with asymmetrical ones. The result of TEE soon after operation showed that 3 patients had tiny residual shunt, 4 had new trivial and mild tricuspid regurgitation (TR). However, no TR worsening, aortic regurgitation (AR), complete atrioventricular heart block, or left or right outflow tract obstruction was detected in all patients. One patient 〖CM(159mm〗with transient atrioventricular block restored to sinus rhythm after 3 days of medical treatment. Five cases (3.7%) were converted to conventional open heart repair during the operation. Followup was done to all the patients for a period ranged from 6 months to 30 months (18.3±6.6 months). Tiny residual shunt in the 3 cases mentioned above vanished during the followup period. No new TR, AR, hemolysis, thrombosis, dislocation of the devices, or outflow stenosis was detected postoperatively. The tiny incision caused less psychologic depression. Conclusion Minimally invasive transthoracic device closure of VSD without CPB is a simple, effective and safe intervention under guidance of TEE for most of perimembranous VSD patients. The short and midterm clinical outcomes are promising. Longterm followup is indispensable.
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.
The main purpose of this study is to observe and analyze the characteristics and the clinical significance of long-term echocardiogram data in patients after mechanical aortic valve replacement operation. Fifty-five cases were recruited over 5 years after mechanical aortic valve replacement operation, with complete echocardiogram examination profiles. The 55 subjects were divided into predominate aortic stenosis group and predominate aortic regurgitation group, based on preoperative examinations. And another way of division was also carried out that according to the effective orifice area index (EOAI), the subjects were divided into three groups, i.e., severe prosthesis-patient mismatch (PPM) group, moderate PPM group, and non PPM group. Characteristics of long-term echocardiogram data of the subjects were analyzed. Patients with aortic stenosis showed significantly decreased thickness of intraventricular septum and left ventricular posterior wall about half a year after operation (P<0.05). Half a year after operation, patients with aortic regurgitation showed decreased left ventricular internal dimension diastole and left ventricular internal dimension systole, and increased ejection fraction (P<0.05). Differences in mean aortic valve pressure gradient, forward blood flow across the aortic valves, and ejection fraction were not significant among those with severe PPM, moderate PPM, and non PPM groups (P>0.05). Number of cases of ascending aorta dimension increased as time goes on and pathogenesis of other valve diseases. A conclusion could be drawn that the heart function of patients with aortic valve disease could be improved after mechanical aortic valve replacement operation, but pathologies in other valves and ascending aorta might be increased, and therefore periodical postoperative echocardiogram evaluation with long tem pharmaceutical therapy could be necessary.
Objective To introduce the application of transcatheter closure of multi-fenestrated atrial septal defect (ASD) via femoral vein under ultrasound guidance with amplatzer cribriform occluder (ACO) and atrial septal defect occluder (ASDO), as well as to assess its feasibility, effectiveness and safety. Methods The clinical data of 48 patients with fenestrated ASD occluded via femoral vein under ultrasound guidance from December 2015 to May 2018 in our hospital were retrospectively analyzed, including 17 males and 31 females, aged 10 months to 51 years, an average of 11.50±13.86 years, and weighting 6-79 (27.00±20.14) kg. Among 48 patients with fenestrated ASD, 12 patients had double-foramen and 13 atrial septal aneurysm combined with defects and 23 multi-foramen. All patients underwent transthoracic echocardiography (TTE) or transesophageal echocardiography (TEE) to complete the closure of fenestrated ASD. Ultrasound, electrocardiogram and chest X-ray were reviewed the next day after surgery to evaluate the curative effect. Results Forty-eight patients with ASD were treated with 49 occluders, due to one patient with two occluders. There were 29 ASDO (8-26 mm) and 20 ACO (18-34 mm). During the operation, TTE/TEE examination showed that 48 patients were completely occluded, 13 patients showed fine bundle shunt in the unreleased push notification rod, and 9 patients had fine bundle shunt after the release of push notification rod. Fine bundle shunt was found in 8 patients 24 hours after operation, and microshunt was found in 3 patients 1 year after operation. All the patients were followed up. The occluder position was good. The right heart was reduced in different degrees, and the X-ray showed that the pulmonary blood was reduced in different degrees. No arrhythmia was found by electrocardiogram after operation. Conclusion It is a safe and effective method to use ACO and ASDO to occlude ASD through femoral approach under ultrasound guidance.

Method The 100 patients with ASD were selected on transthoracic echocardiography (TTE) and TEE. During operation, TEE was applied to monitor the procedure of occlusion, to guide the occluder cites, to evaluate the effects and to make sure if there were peripheral residual shunts around the occlusion and other complications. Results All of the patients were exactly diagnosed by TTE and TEE，guiding and evaluating the successful closed ASD. The successful rate of occlusion was 96%，the failure rate was 4%. The review after surgery showed that, there were no residual review, pleural effusion in three patients. The concordance rate of TTE and TEE diagnosis result is 40%. TEE diagnosis amend the preoperative TTE diagnosis in 60 patients (60%). Conclusions TEE plays an important role in select inpatients，determining the size of the occluder，correctly before occlusion operation, guiding the placement of the occluder in operation and evaluating the effect after operation.
ObjectiveTo explore the value of transthoracic echocardiography (TTE) to monitor and evaluate aortic insufficiency (AI) within one year after the implantation of the left ventricular assist device (LVAD).MethodsWe retrospectively collected and analyzed the TTE data of 12 patients who received LVAD implantation from 2018 to 2020 in our hospital. All patients were males, with an average age of 43.3±8.6 years. We analyzed temporal changes in the aortic annulus (AA), aortic sinus (AoS), ascending aorta (AAo), the severity of AI and the opening of aortic valve before operation and 1 month, 3 months, 6 months and 12 months after LVAD implantation.ResultsAll 12 patients survived within 1 year after LVAD implantation. One patient was bridged to heart transplantation 6 months after implantation, and two patients did not receive TTE after 3 and 6 months. Compared to pre-implantation, AoS increased at 1 month after implantation (31.58±5.09 mm vs. 33.83±4.69 mm). The inner diameters of AA, AoS and AAo increased at 3, 6 and 12 months after LVAD implantation compared to pre-implantation (P<0.05), but all were within the normal range except for one patient whose AoS slightly increased before operation. After LVAD pump speed was adjusted, the opening of aortic valve improved. The severity of AI increased at 6 and 12 months after LVAD implantation compared to pre-implantation, and increased at 12 months compared to 6 months after LVAD implantation (P<0.05).ConclusionTTE can evaluate aortic regurgitation before and after LVAD implantation and monitor the optimization and adjustment of LVAD pump function, which has a positive impact on the prognosis after LVAD implantation.
