    • 摘要: 目的 回顾性研究围术期严重高血糖对心肺转流(C PB)心脏瓣膜置换术患者术后并发症及预后的影响.方法 将211例CPB心脏瓣膜置换术的患者根据围术期最高血糖值进行分组(≥13.9 mmol/L为严重高血糖组,<13.9 mmol/L为非严重高血糖组),收集所有患者围术期血糖值、一般资料及手术资料.采用t检验、χ2检验或者Fisher确切概率法对2组患者进行术前、术中和术后资料分析,采用Logistic回归和线性回归方程分析并发症的危险因素.结果 围术期血糖≥13.9 mmol/L为肺部感染的危险因素(OR=2.20,95%CI=1.26~3.83,P=0.005),机械通气时间(Coef.=0.42,P<0.001)、ICU住院时间(Coef.=0.53,P<0.001)和住院时间(Coef.=0.42,P=0.007)均与围术期血糖最大值呈正相关.结论 心脏瓣膜置换术围术期严重高血糖是肺部感染的危险因素,围术期高血糖与延长的机械通气时间、IC U住院时间和总住院时间相关.

    • 摘要: 目的 总结经导管主动脉瓣置换术(TAVR)中应用左心室导丝起搏技术的初步经验.方法 本研究为回顾性研究.收集2019年10至12月于中国医学科学院阜外医院应用左心室导丝起搏技术行TAVR治疗的患者13例.收集患者的临床资料、手术操作,术中密切观察血压、心电图变化,行升主动脉造影评估瓣膜释放后主动脉瓣反流情况,记录院内和出院3个月随访期间主要心脏不良事件的发生情况.结果 本研究共纳入13例患者,其中男性7例,年龄为(73.8±8.3)岁.13例患者中三叶式主动脉瓣9例,二叶式主动脉瓣3例,主动脉瓣人工生物瓣置换术后1例.所有患者均在左心室导丝起搏下完成球囊扩张和瓣膜释放,球囊扩张时,以180次/min起搏后,血压均能降至60 mmHg(1 mmHg=0.133 kPa)以下;瓣膜释放过程顺利,位置稳定.升主动脉造影结果显示,瓣膜释放后无反流7例,轻度反流5例,中度反流1例.术中有3例患者因三度房室传导阻滞经股静脉置入临时起搏导线,其中1例住院期间置入永久起搏器,另外2例术后24h内传导恢复.另有1例患者,术中心电图无明显变化,术后10d出现三度房室传导阻滞,置入永久起搏器.其余10例患者均在术后24h开始进行床旁活动、康复训练.住院及出院3个月随访期间无死亡、心肌梗死、卒中等主要心脏不良事件发生.结论 TAVR中使用左心室导丝起搏是安全、可行的.

    • 摘要: Objective To analyze the early efficacy of bipolar radiofrequency ablation procedure for atrial fibrillation during the heart valve replacement. Methods Clinical data of 122 patients with heart valve disease and atrial fibrillation (AF) in our hospital were randomly selected as research subjects. Valve replacement and concomitant bipolar radiofrequency ablation was performed for a observation group (n=70) while only the valve replacement was performed for a control group (n=52). Both groups were observed for the duration of mechanical ventilation, ICU stay time, the rate of malignant arrhythmia, LVEF and LVDd index. The clinical efficacy was evaluated according to the electrocardiogram and echocardiogram after the opration. Results On the mechanical ventilation time, ICU stay time, the rate of malignant arrhythmia, as well as LVEF, the observation group was significantly better than the control group,and the difference was statistically significant (P0.05). 结论 瓣膜置换同期双极射频消融治疗心房颤动的早期疗效显著,值得临床推广应用.

    • 摘要: 近年来,钙化性主动脉瓣狭窄(CAS)发病率呈现逐年上升趋势,患者出现心绞痛、呼吸困难和晕厥等严重威胁生命的临床症状,导致预后极差.外科瓣膜置换术能够明显改善患者的生存质量及预后.然而,传统的外科手术可能导致严重的并发症,尤其是高龄、术前合并其他疾病的患者,因此,超过30%的患者未能接受手术治疗.为解决这一问题,经皮穿刺导管介入的微创技术应运而生.经导管主动脉瓣植入(TAVI)术是将人工生物瓣膜嵌入导管内并在病变的主动脉瓣原位释放的技术.多项临床研究已经表明,TAVI手术能够显著降低病死率,目前全球已完成超过40万例.随着临床数据的积累,TAVI手术的适应证有望进一步扩大.在欧美发达国家已经积累了较为丰富经验的基础上,TAVI介入技术自2010年开始引进我国,初步临床疗效确切,为我国此类患者点燃了生命的希望.虽然现阶段TAVI手术并不是主动脉瓣疾病治疗的金标准,但微创或无创的治疗方法代表着未来瓣膜外科的发展方向.%The incidence of calcific aortic stenosis(CAS)is increasing year by year.Patients with CAS suffer symptoms of angina,dyspnea,syncope as a consequence and poor prognosis.Surgical valve replacement can significantly improve the life quality and prognosis of patients. However, traditional surgery can lead to serious complications, especially for older patients with preoperative complications.As a result,more than 30% of patients were unable to undergo surgical treatment. Transcatheter aortic valve implantation (TAVI), a technique in which a bioprosthetic valve is inserted via a catheter and implanted within the diseased native aortic valve,is a new therapeutic modality for treatment of older patients with severe comorbidities. Many clinical studies have showed that TAVI can significantly reduce mortality. That over 400 000 TAVI procedures have now been performed worldwide. With the accumulation of clinical data, the indications for TAVI can be expanded to young and low risk patients.On the basis of the rich experience accumulated in developed countries in Europe and America,TAVI intervention technology has been introduced in China since 2010.It has a definite clinical effect,which has kindled the hope of life for such patients in our country.Although TAVI surgery is not the gold standard for the treatment of aortic valve disease at the present stage,minimally invasive or noninvasive therapy represents the development direction of the future valvular surgery.

    • 摘要: The hybrid technique is a technique that combines minimally invasive cardiac surgery with intracardiac intervention. It has the advantages of definite curative effect, good visual field and slight trauma. It provides advanced treatment options for patients with cardiovascular diseases.With the gradual improvement of technical level,diagnosis and treatment concept and medical equipment,especially the popularization of"hybrid operation room",hybridization technology has been applied in many sub-specialized fields of cardiac surgery. In some fields this technology has become a routine treatment program.At present,it is mainly used for treatment of congenital heart disease,coronary heart disease,heart valve disease,aortic disease and atrial fibrillation.%杂交技术(hybrid technique)是将微创心脏外科技术和心内介入技术结合的技术,具有疗效确切、视野良好、创伤微小的优点,为心血管疾病患者提供了先进的治疗选择.随着技术水平、诊疗意识、医疗设备的逐步提高,特别是"Hybrid手术间"的逐渐普及,杂交技术已经在心外科的多个亚专业领域开展应用,个别领域已成为常规治疗方案.目前主要应用于先天性心脏病、冠心病、心脏瓣膜病、主动脉疾病、房颤等的治疗.
