Objective To compare surgical results between real-time three dimensional echocardiography（RT-3DE） guided closure of atrial septal defect （ASD） through a right minithoracotomy and traditional surgical repair under cardiopulmonary bypass （CPB）. Methods Sixty-four patients with secundum ASD received surgical repair in the First People’s Hospital of Honghe Autonomous Prefecture from April 2009 to April 2012. According to different surgical approach, all the patients were divided into group A and B. In group A, 35 patients underwent traditional ASD repair under CPB including 20males and 15 females with their age of 12-56 （16.4±4.0） years. In group B, 29 patients received real-time RT-3DE guidedASD closure through a right minithoracotomy without CPB, including 20 males and 15 females with their age of 15-50 （18.5±0.2） years. Operation time，postoperative mechanical ventilation time，hospital stay，chest drainage，mortality，morbidity and follow-up outcomes were compared between the 2 groups. Results Operation time （110.47±35.90 minutesvs. 159.32±20.60 minutes），postoperative mechanical ventilation time （10.40±22.30 hours vs. 16.40±12.20 hours），chestdrainage （106.71±85.20 ml vs. 146.70±75.63 ml）and postoperative hospital stay （4.0±1.0 days vs. 7.0±1.0 days）ofgroup B were significantly shorter or less than those of group A. In group A, 1 patient died postoperatively and 7 patientshad postoperative complications. In group B, there was no in-hospital mortality and 3 patients had postoperative complications.Postoperative morbidity of group A was significantly higher than that of group B （20.0% vs. 10.3%，P＜0.05） . ConclusionFor ASD patients with definite surgical indications，RT-3DE guided ASD closure through a right minithoracotomy has more advantages over traditional surgical repair under CBP.
This study was an interpretation study based on the standard of AGREEⅡ. It analyzed methodological perspective of the International Evidence-Based Recommendations for Focused Cardiac Ultrasound determined by the International Conference on Focused Cardiac UltraSound (IC-FoCUS).
Objective To systematically review whether the prevalence of left ventricular diastolic dysfunction was higher in systemic sclerosis (SSc) patients. Methods The Cochrane Library, PubMed, EMbase, CBM, CNKI and WanFang Data databases were electronically searched to collect the studies about comparing echocardiographic parameters in SSc patients and controls from January 1990 to June 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software. Results A total of 22 studies involving 1 146 patients were included. The results of meta-analysis showed that: compared to controls, patients with SSc had prolonged left isovolumetric relaxation time (MD=10.40, 95%CI 4.04 to 16.77, P=0.001), higher trans-mitral A-wave velocity (MD=0.11, 95%CI 0.07 to 0.15, P<0.000 01), prolonged mitral deceleration time (MD=8.04, 95%CI 2.66 to 13.42,P=0.003), larger mean left atrial dimension (MD=1.43, 95%CI 0.11 to 2.76, P=0.03), higher estimated pulmonary artery pressure (MD=11.35, 95%CI 6.08 to 16.6, P<0.001), higher E/E’ ratio (MD=2.08, 95%CI 0.19 to 3.96,P=0.03) and lower trans-mitral E-wave velocity (MD=–0.03, 95%CI –0.05 to –0.01, P=0.000 3), mitral E/A ratio (MD=–0.24, 95%CI –0.32 to –0.15, P<0.000 01) and trans-mitral E’-wave velocity (MD=–1.52, 95%CI –2.44 to –0.60,P=0.001). There were no differences in left ventricular ejection fraction, isovolumetric end-systolic dimension, septal end-diastolic thickness and posterior wall end-diastolic thickness, trans-mitral A’-wave velocity, E’/A’ ratio. Conclusion SSc patients are more likely to have echocardiographic parameters of LVDD. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusion.
Cardiac lipoma is rare and benign entities of heart, and often discovered after autopsy incidentally because most patients remain completely asymptomatic. The symptoms of cardiac lipoma depend on their location and size within the heart, such as dyspnea, chest pain, arrhythmia, and even sudden death. Surgical interventions usually have good results. Up till now, there has been no any relevant large-scale randomized controlled trial, and even no precise guideline for treatment. Surgical procedures often depend on patients' clinical manifestations and changes of hemodynamics in cardiac vessels in order to relief the symptoms as well as abort the progress of the disease. Therefore, early diagnosis and close follow-up are necessary for timely treatment. This article aims to summarize the imageological examinations for cardiac lipoma, including echocardiography, computed tomography, magnetic resonance imaging along with their characteristics and advantages, in order to get better clinical strategies.
ObjectivesTo systematically review the teaching efficacy of cardiac ultrasound simulation.MethodsCNKI, VIP, PubMed, EMbase and The Cochrane Library databases were electronically searched to collect randomized controlled trials (RCTs) on cardiac ultrasound simulation from inception to March 7th, 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 7 RCTs involving 300 trainees were included. The results of meta-analysis showed that: compared with traditional teaching method, trainees who received cardiac ultrasound simulation obtained higher cardiac ultrasonic structure image recognition score (SMD=1.38, 95%CI 0.81 to 1.94, P<0.000 01), higher ultrasonic image quality score (SMD=2.08, 95%CI 1.71 to 2.44, P<0.000 01), and shorter time required to obtain the correct ultrasound image (SMD=−1.19, 95%CI −1.55 to −0.83, P<0.000 01).ConclusionsThe current evidence shows that trainees who received cardiac ultrasound simulation have superior teaching effect immediately after the training compared with those who received traditional teaching method. However, further high-quality researches are needed to confirm whether there is a difference between the two training methods in long-term teaching effect.
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.
