ObjectiveTo explore the safety and efficacy of transesophageal echocardiography (TEE)-guided percutaneous intervention for patent ductus arteriosus (PDA) in obese teenagers.MethodsFrom January 2018 to June 2019, 21 obese teenagers with PDA treated with femoral artery occlusion guided by TEE in the Department of Cardiac Surgery, Dalian Children's Hospital of Dalian Medical University were included in this study, including 13 males and 8 females aged 12.8-17.3 (15.1±1.7) years, with an average weight of 51.0-89.0 (73.4±10.1) kg. The operative effect was evaluated. ResultsAll patients successfully received the surgery, and none was changed to radiation-guided or thoracotomy ligation. The average operating time was 23.9±6.8 min, the average postoperative hospitalization time was 3.8±0.6 d. No peripheral vascular injury, intracardiac infection or pericardial effusion occurred. The mean follow-up time was 19.5±4.9 months, and the results of all reexaminations were good.ConclusionFor some PDA children with obesity, emphysema or thoracic malformation, it is difficult to block PDA by transthoracic ultrasound-guided percutaneous intervention, and TEE can avoid the interference of chest wall and lung qi, or other factors. It is an effective supplementary guidance method worthy of promotion.
In recent years, transesophageal echocardiography has a trend toward miniaturization, so it has great clinical significance and broad clinical application prospect in the management of Cardiac Surgery ICU patient. This paper presents the characteristics of miniaturized transesophageal echocardiography and its clinical application. And we also focused on the contrast between miniaturized transesophageal echocardiography and standard transesophageal echocardiography and transthoracic echocardiography.
目的探讨在经食管超声心动图（TEE）引导下经胸封堵室间隔缺损（VSD）的临床经验。 方法回顾性分析2013年7月至2014年7月高州市人民医院23例先天性心脏病患儿的临床资料，其中男9例、女14例，年龄4个月至1岁。胸骨下段小切口暴露右心室前壁，在TEE引导和实时监测下，穿刺右心室前壁，建立轨道，通过短输送装置直接将封堵器安放在VSD部位。 结果23例患者全都封堵成功，置入封堵器直径6～10 mm，术后5～11 d出院，随访3～24个月，无残余分流、主动脉瓣反流以及心律失常等并发症。 结论TEE引导下经胸微创封堵婴儿室间隔缺损是一种简单安全的治疗方法。
Echocardiography is an important imaging technique in mithal valve transcatheter edge-to-edge repair (TEER). During the operation, mitral leaflets capture and clamping have the highest requirements for ultrasound image quality and should be performed under the guidance of high-quality commissural view. However, standard commissural view cannot be obtained in some patients due to cardiac enlargement, transposition or limited esophageal acoustic window. In this condition, the optimal view can be obtained by Multivue technology. This paper reports a male patient aged 67 years with successful mitral valve TEER under the real-time guidance of Multivue technology, and summarizes the key points of this technology.
ObjectiveTo evaluate the feasibility and safety of blocking congenital ventricular septal defect or congenital atrial septal defect through the small vertical incision of right subaxillary. MethodsWe retrospectively analyzed the clinical data of 38 patients underwent the surgery of blocking congenital ventricular septal defect or congenital atrial septal defect in our hospital from January to August 2015. There were 22 males and 16 females with a mean age of 10.3±5.2 months, weight of 8.2±3.5 kg. ResultsThere were 34 patients (89.5%) successfully blocked through the small vertical cut of right subaxillary. The average blood loss of those 34 patients was 19.5±13.4 ml and the mean time of surgery was 58.4±28.5 minutes. Four patients (10.5%) with ventricular septal defect failed to block because of aortic valve prolapse. Those patients underwent direct repair of ventricular septal defect under extracorporeal circulation while general anesthesia. There was no serious adverse event during the surgery. The extubation time was 3.9±1.6 hours, the ICU monitoring time was 1.8±0.8 days and the hospital stay time was 3.2±0.5 days. All patients discharged uneventfully. ConclusionBlocking congenital ventricular septal defect or congenital atrial septal defect through the cut of right subaxillary is a feasible, effective, safe, and minimally invasive method. The effect of early follow-up is well.
Aortic stenosis accounts for a large proportion of valvular heart disease in China. This article described an unusual case of severe aortic stenosis with severe cardiopulmonary decompensation treated by emergency transcatheter aortic valve replacement. Preoperative assessment was performed by transesophageal echocardiography. The extracorporeal membrane oxygenation team was informed to be ready. During the operation, no obvious perivalve leakage was observed after valve released. The transvalvular pressure gradient decreased to 7 mm Hg (1 mm Hg=0.133 kPa).The patient’s symptoms were completely relieved after the operation, and no adverse events occurred during the hospitalization. After discharge, color Doppler echocardiography showed that stenosis was eliminated, cardiac function was improved, no significant perivalvular leakage was observed, and pulmonary hypertension reduced to moderate. The success of this operation confirmed the efficacy of emergency transcatheter aortic valve replacement, and showed that after a rigorous evaluation, emergency transcatheter aortic valve replacement may be a reasonable choice for patients with severe aortic valve stenosis.
目的探讨临床应用微创经胸小切口封堵术治疗室间隔缺损（ventricular septal defect，VSD）的初步经验 方法回顾性分析我院心外科2006年4月至2013年12月施行微创经胸小切口封堵术治疗205例VSD患者的临床资料。其中，男112例、女93例，年龄4个月～62（10.2± 12.5）岁，无合并其它心内畸形，术前经胸超声心动图筛查，术中经食管超声心动图监测、引导，胸骨下段小切口或左胸第3肋间胸骨旁小切口行VSD封堵术。术后密切随访病情，定期随访心电图、胸部X线片（后前位+左侧位）、超声心动图。 结果全组患者无死亡。封堵成功200例（97.6%），封堵失败转行体外循环下手术修补5例，术后并发VSD残余漏3例，无新发主动脉瓣及三尖瓣反流、封堵伞脱落、二次开胸、完全性房室传导阻滞、溶血等并发症。 结论微创经胸小切口VSD封堵术安全、有效，技术日臻成熟，临床应用值得推广，但仍需注意团队医师间配合以及指征把握。
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.
We reported a 65-year-old female who was admitted to our institute with "recurrent subxiphoid pain accompanied by dyspnea for more than 10 days". Electrocardiogram examination suggested acute extensive anterior ST segment elevation myocardial infarction. Preoperative transthoracic echocardiography suggested ventricular septal rupture. The patient was planned for the repair of ventricular septal rupture with cardiopulmonary bypass. The formation of left ventricular aneurysm was diagnosed by intraoperative transesophageal echocardiography (TEE). The surgeon decided to abdopt the modified incision of left ventricular approach guided by TEE, which greatly improved the prognosis of the patient. The surgery duration was 197 min, aortic cross-clamping time was 56 min, cardiopulmonary bypass time was 69 min, and the patient was safely admitted to ICU after the surgery. Extubation was performed on the first day postoperatively, and the intra-aortic balloon pump support was retreated on the second day postoperatively. Postoperative echocardiography showed that no obvious residual shunt was observed after ventricular septal repairment and ventricular aneurysm resection. The patient was discharged on the 12th day after the surgery. Additionally, the mental condition was good and daily activities were not limited within 6 months postoperatively.
