心房纤颤的改良式迷路手术

介绍治疗心房纤颤的改良式迷路手术。通过对１例风湿性心脏病二尖瓣狭窄兼关闭不全、三尖瓣关闭不全、左房内血栓形成、心房纤颤１０ａ的患者行二尖瓣替换术、左房内血栓清除术和改良式迷路手术，介绍其手术方法。患者术后即刻恢复了窦性心律，效果良好，痊愈出院。认为该手术是目前对心房纤颤的治疗、恢复心房收缩功能、房室收缩顺序性及窦性心律的有效方法。     

心瓣膜病合并冠心病的诊治

心内膜病在心血管疾病总发生率中占较大比例。不同病因的心血管疾病 ,可分别或同时引起心内膜病变 :如心内膜炎、心瓣膜狭窄、关闭不全、脱垂、粘液样变性、纤维化、钙化、或撕裂等 ,这些病变可引起心功能损害 ,有时需急诊治疗。为加深对心内膜病的全面认识 ,了解心内膜病的临床现状及国内外进展概况 ,本刊编辑部邀请国内心血管病的临床专家就心内膜病的病因 ,临床、诊断、药物治疗、手术治疗及介入治疗等多方面作了专题论述评价 ,这对提高本病的诊疗防治水平有助益 ,也可作为医学继续教育的参考读物     

埋藏式人工心脏双腔起搏器的护理

埋藏式人工心脏双腔起搏器主要用于治疗严重缓慢型心律失常 ,抢救危重病人[1] 。是一种具有双腔起搏、双腔感知以及触发和抑制双重反应方式的房室全能型起搏器。为了使患者能尽快适应起搏器 ,提高手术成功率 ,加强护理工作尤为必要。1　术前护理1.1　心理护理　接受埋藏式人工心脏双腔起搏器术患者大多有怀疑、焦虑、不安、恐惧等心理 ,因此 ,责任护士应事先做好患者和家属思想工作 ,使患者充分了解手术目的与过程 ,解除顾虑 ,积极主动配合手术。手术前 1天晚上可给地西泮口服 ,让病人充分休息。1.2　术前准备　对择期安置双腔起搏器的患者…     

心脏瓣膜置换的术后护理与健康教育

心脏瓣膜置换患者,其临床特点为病程长、心脏功能差、合并症多,经内科治疗无效者方选择手术[1].笔者所在医院2007～2008年共对25例风湿性心脏病患者实行瓣膜置换术,手术效果满意,仅就术后有关护理问题总结如下.     

心脏瓣膜病患者冠心病发生率分析

目的:明确冠心病在心脏瓣膜疾病中的发生率.方法:对301例心脏瓣膜病患者进行选择性冠状动脉造影并结合其他临床结果进行综合分析.结果:冠状动脉造影显示,301例患者中43例存在冠状动脉狭窄,男28例,女15例.其中二尖瓣膜病患者男12例,女7例,主动脉瓣膜病患者男6例,女1例,联合瓣膜病患者男10例,女7例.结论:冠心病在心脏瓣膜疾病中有较高的发生率,但在不同瓣膜疾病中并没有发现存在差异性.     

升主动脉成形术中期效果分析

Objective Reduction ascending aortoplasty is an alternative procdure to the replacement of the ascending aorts in case of ascending aorta dilation. However,its applicabikity is still under debate.This retrospective study was designed to evaluuate the midterm follow-up of unsupported ascending reduction aortoplasty for of the ascending aorta in petients with aortic valve dis- ease.Methods From October ,1996 to April,2007, a total of 54 patients with aortic valve disease and dilatation of the ascending aorta underwent unsupported reduction aortoplasty in combination with aortic valve replacement at our institution The diameter of the ascending aorta was measyred before and early after sugery and then later between 13 and 96 menths [mean (23 ±16)months] posto- perativeiy using echocardiography.Results Two patients were dead with thean overall perioperative mortality rate was of 3.7%. The reduction aortoplasty decreased the diameter of the aorta from (45.77±6.02) mm p～eope～afive]y to (34.67 ～4.81) mm early after surgery (P<0.01). During follow-up, the diameter d aorta increased from (34.67±4.81) mm early after surgery to (37.65± 6.35) mm after a mean follow-up of (23±16) months (P<0.01), including the diameters are greater than > 45 mm within 5 pa- tients. Aortic stenosis and an early postoperative diameter greater than 40 mm m'e independent risk factors for redilatation. Conchusion Because of the unsatisfied midterm follow-up redilation of unsupported reduction aortoplasty for dilation of the ascending aorta with aortic valve disease, this group of patients needs continued intimate fallow-up or even reoperation. The patients of stenosis is the surtable indication for RAA, and it is necessary to reduce the diameter of aorta to be lees than 40 mm to prevent redilation.     

左室假腱索患者的心功能分析

近年来,随着超声诊断技术的提高及推广应用,左室假腱索(LVFT)的检出率趋于提高,其临床意义逐渐得到关注。笔者检测42例LVFT者的左室收缩时间间期(STI)及心尖搏动图(ACG),探讨LVFT对心功能的影响,着重分析LVFT伴心脏杂音或室性早搏患者的心功能状况。1 对象与方法 经二维超声心动图或彩色多普勒超声心动图确诊的LVFT者42例(男25例,女17
