目的 总结单心室瓣膜反流的外科治疗经验，观察治疗效果。 方法 回顾性分析2006年7月至2012年1月上海交通大学医学院附属新华医院61例单心室患者的临床资料，其中男36例，女25例；手术年龄2个月至 20岁；体重2～58 kg。右心室型41例，左心室型13例，未定型型7例。根据瓣膜反流程度不同分为3组，无/微量反流组：28例，瓣膜未行处理；轻/中度反流组：21例，瓣膜未行处理；重度反流组：12例，手术同期行瓣膜成形。收集所有患者住院及随访资料，分析轻/中度反流组、重度反流组瓣膜反流变化趋势，以及影响瓣膜反流的因素。结果 住院死亡5例，住院死亡率8.2% （5/61）。重度反流组患者行瓣膜成形术后反流程度较术前明显减轻（由术前4.00级下降至术后2.08级）。随访56例，随访时间6～38个月，重度反流组随访10例，随访期间死亡2例，其余8例中重度反流2例，中度反流3例，轻度反流2例，微量反流1例；瓣膜反流程度增加趋势明显（由术后平均2.08级增加至平均2.75级）。轻/中度反流组随访19例，随访中无死亡，其中反流程度增加至重度3例（原1例轻度反流，2例中度反流），反流程度由轻度增加至中度3例，瓣膜反流程度由术后平均2.33级增加为平均2.58级。轻/中度反流组瓣膜反流增加率与无/轻微反流组比较差异无统计学意义（瓣膜反流增加率为31.5% vs. 19.2%，χ2=0.36，P=0.55）。单因素分析结果显示，瓣膜反流增加者在随访过程中心功能较瓣膜反流无变化或减轻者明显降低（术后左心室射血分数53.11%±5.61% vs. 59.65%±3.32%，t =-5.49，P=0.00），而左心室舒张期末容积较瓣膜反流无变化或减轻者明显增加（t =2.58，P=0.01）。 结论 单心室合并重度瓣膜反流行瓣膜成形术近期效果较好，但随着心功能下降、心室扩张，瓣膜反流程度加重趋势明显；轻/中度瓣膜反流可暂不进行处理，但部分患者瓣膜反流有增加趋势，提示应注重术后随访。
Objective To investigate clinical features and treatment strategy of cardiac complications caused by permanent pacemaker （PPM） implantation.?Methods?We retrospectively reviewed clinical records of 10 patients with cardiac complications caused by PPM who received surgical treatment in General Hospital of People’s Liberation Army from January 2003 to May 2010. There were seven males and three females with an average age of 62.9 years. One patient had an Atrial demand inhibited pacemaker （AAI） PPM and the other nine patients had a DDD PPM. Cardiac complications included infective endocarditis （IE） in 5 patients, tricuspid insufficiency （TI） in 4 patients and pulmonary artery thrombosis in one patient. According to their respective situation, these patients underwent different surgical treatment such as tricuspid valve plasty （TVP）， tricuspid valve replacement and/or removal of PPM lead and vegetations as part of intensive debridement of the infected area.?Results?Postoperatively， all the patients were successfully discharged. Five patients whose PPM lines and leads were preserved in the surgery had normal PPM function. Three PPM-dependent patients whose PPM leads were removed in the surgery received a PPM reimplantation later. Nine patients were followed up for an average of 5.5 months and all these patients had a significantly improved quality of life. One patient after TVP had mild TI during follow-up. Conclusion Surgical treatment should be performed as early as possible when infection is too severeto control in patients with IE caused by PPM. PPM-induced TI may be hard to be diagnosed preoperatively, and transesophageal echocardiography or surgical exploration should be considered to establish the diagnosis. Measures should be taken to protect PPM if PPM lines and leads are preserved during operation. Patients whose PPM lines and leads are removed during the surgery need to choose a suitable time for PPM reimplantation.
Objective To summarize the clinical experiences of venoarterial extracorporeal membrane oxygenation (ECMO) which provides temporary cardiopulmonary assist for critical patients, and preliminary analysis of the cause of failure. Methods From February 2005 to October 2008, 58 adult patients (male 42, female 16) undergoing cardiogenic shock required temporary ECMO support. Age was 44.8±17.6 years, and support duration of ECMO was 131.9±104.7 hours. There were 24 patients (41.4%) with coronary heart disease, 11 patients (19.0%) with cardiomyopathy, 10 patients (17.2%) with cardiac valve disease,and 9 patients (15.5%) with congenital heart disease. Results 22 patients died in hospital. 11 patients (50%) died of multisystem organ failure, 5 patients (22.7%) died of refractory heart failure despite the ECMO support. Another patients died of bleeding and severe pulmonary hypertension etc. The percentage for patients need cardiac resuscitation before ECMO support and patients with acute renal failure treated by continuous renal replacement therapy (CRRT) under ECMO support were obviously higher in dead patients than those in survivor patients (45.5% vs.19.4%, 40.9% vs. 5.6%; P=0.043，0.001). All of the discharged patients were reassessed, mean followup time were 15.6 months. Three patients died of refractory heart failure， 1 patient died of neurologic complications. The other 32 survivors were in good condition with cardiac symptom of New York Heart Association class Ⅰ or Ⅱ. Conclusion ECMO offers effective cardiopulmonary support in adults. Early intervention and control of complications could improve our results with increasing experience. Combining using CRRT during the ECMO support is associated with significantly higher mortality rate. Suffered cardiac arrest prior to ECMO also influences the survival.
Objective To discuss how is the perinatal infant’s prognosis influenced by different cardiac function and types of heart disease in pregnant women with heart disease, and to check the importance of antenatal examination. Method Retrospective analyses were conducted on the clinical records of 102 pregnant women hospitalized due to heart disease from February 2002 to February 2011 in the First Affiliated Hospital of Xinjiang Medical University. According to the level of cardiac function, 61 patients were divided into the Level I-II group and the other 41 patients were in the Level III-IV group. Results Of all cases, 38 were congenital heart disease (37.25%), followed by 22 arrhythmia (21.57%), 17 rheumatic heart disease (16.67%), 15 perinatal cardiomyopathy (14.71%), 7 hypertensive heart disease and 3 other types of heart disease. The average gestational weeks were shorter and the neonate’s weight was lower in the Level III-IV group than the Level I-II group, with a significant difference (Plt;0.05); the incidence of premature delivery, low birth weight infant at normal gestational age, neonatal asphyxia and perinatal mortality was higher in the Level III-IV group than the Level I-II group, with a significant difference (Plt;0.05); the rate of regular antenatal examination was higher in the Level III-IV group than the Level I-II group, with a significant difference (P=0.008); and there were significant differences between the regular and irregular examination groups in the incidence of premature delivery and low birth weight infant at normal gestational age (Plt;0.05), but no significant differences were found in the incidence of asphyxia and perinatal mortality (Pgt;0.05). Conclusions Congenital heart disease is the most commonly-seen type in the pregnant women with heart disease. The maternal cardiac function directly impact the prognosis of perinatal infant, and the regular antenatal examination, timely diagnosis and treatment can improve pregnancy outcome.
ObjectiveTo analyze the incidence of heart disease, its clinical manifestations and risk factors in patients with polymyositis (PM) and dermatomyositis (DM). MethodWe collected the clinical data of 138 PM (n=78) and DM (n=60) patients treated between January 2008 and March 2014, among whom there were 64 males and 74 females with an average age of (48.5±19.6) years old, and an average disease course of (84.5±6.9) months. We analyzed their incidence of heart disease, its clinical manifestations and the risk factors. Subsequently, we adopted single-factor analysis to analyze such factors as age, gender, disease course, kinds of disease, creatine kinase (CK), CK-MB, CK-MB/CK, troponin T, antinuclear antibodies, anti-SSA antibody, erythrocyte sedimentation rate, C-reactive protein, disease activity score, muscle force, pulmonary interstitial lesions and pulmonary artery hypertension. ResultsThere were 59 (42.7%) patients with heart disease, 48 (34.8%) with abnormal electrocardiogram, and 52 (37.7%) with abnormal color Doppler ultrasound results. Logistics multiple factors regression analysis found that the course of the disease (OR=1.669, P=0.010), myositis disease activity score (OR=7.456, P<0.001), pulmonary interstitial lesions (OR=4.568, P=0.014) were risk factor for heart disease in PM/DM patients. ConclusionsLong disease course duration, high myositis activity score and pulmonary interstitial lesions are strong predictors for heart damage in PM/DM patients.
ObjectiveTo summary the safety and efficiency of the minimally invasive direct cardiac surgery (MIDCS) approach in elderly patients with heart disease. MethodsWe retrospectively analyzed the clinical data of 60 patients underwent MIDCS in Beijng Anzhen Hospital between April 2010 and January 2013. There were 34 males and 26 females with mean age of 66.4±4.8 years and mean weight of 66.1±10.6 kg. ResultsMean cardiopulmonary bypass time and aortic cross-clamp time was 141.2±57.2 minutes and 99.8±37.6 minutes respectively. A total of 37 patients (90.2%) recovered to beat automatically after heart ceased operation. Median mechanical ventilation time was 17.1±9.1 hours. Mean intensive care unit stay was 22.1±12.2 hours. Mean post operative hospital stay was 7.0±2.5 days. Mean incision length was 5.3±0.9 cm. Mean pericardial draining volume was 466.6±412.1 ml in the first day after operation. No transfusion occurred in 27 (45.0%) patients. Early postoperative mortality was 3.3% (2/60). There were 2 patients of reexplorations for bleeding, 1 patient of the twice tracheal intubation, 1 patient of cardiac arrest after operation, 2 patients of poor healing of skin incision, and 1 patient of injury of right phrenic nerve. When leaving hospital, 47 patients were in heart functional class Ⅰ, 8 patients in class Ⅱ, and 3 patients in class Ⅲ. ConclusionMIDCS is associated with good operative effect in the near future with superior safety and broad application range in elderly patients with heart disease.
Objective To explore the feasibility and option of different surgeries for neonates with pulmonary atresia and ventricular septal defect (PA/VSD) through assessing the effect of common surgeries. Methods Fourteen neonates who underwent their first surgery in our center from July 2004 to October 2014 were included. Their basic characteristics, operation and pre- and postoperative clinical information were extracted. Follow up was conducted and the last visit was on October 10, 2016. Short- and midterm survival and total correction rate were compared among different surgeries. Results Among the 14 patients, there were 4 (28.6%) patients, 6 (42.9%) and 4 (28.6%) who underwent one-stage repair, right ventricular outflow tract (RVOT) reconstruction, and systemic to PA shunt operation respectively. The overall in-hospital mortality after the first operation was 28.6% (4/14). At last visit, no death occurred resulting the 5-year survival rate of 71.4% (10/14). The overall total correction rate for all neonates was 64.3% (9/14). Although no statistical difference was found in the mortality among the one-stage repair , RVOT reconstruction and systemic to PA shunt group(50.0% vs. 33.3% vs. 0.0%, P=0.280), the survival and hazard analysis implied better outcomes of the systemic to PA shunt palliation operation. There was no statistical difference in the total correction rate and months from the first palliative operation to correction between those who underwent RVOT reconstruction and systemic to PA shunt (75.0% vs. 50.0%, P=0.470; 32.0 months vs. 18.0 months, P=0.400). Conclusion Performing surgeries for neonates with PA/VSD is still a great challenge. However, the midterm survival rate was optimistic for the early survivors. Systematic to PA shunt seemed to be a better choice with lower mortality for the neonates with PA/VSD who need the surgery to survive.
