射频导管消融治疗特发性室性心动过速的初步观察

特发性室性心动过速(idiopathic ventficular tachycardia,IVT)指目前检查方法未发现明确器质性心脏病证据的室性心动过速(VT),射频导管消融治疗(RFCA)有很高的成功率和安全性[1].     

心大静脉远端室性心律失常射频消融术的护理

特发性室性心律失常（VAs ）,包括特发性室性期前收缩（PVCs ）和特发性室性心动过速（IVT ）,是最常见的心律失常,大多数为无结构性心脏病。经导管射频消融（RFCA ）是治疗室性心律失常的有效方法,近年来,经心内膜途径导管射频消融治疗PVCs／IVT逐年增加。然而,左心室心外膜VAs起源者经左心室心内膜消融无效而需经心外膜消融才能成功。Daniels等报道心外膜起源IVT的发生率可达9％。

特发性室性心动过速(idiopathic ventricular tachycardia, IVT)发生于无器质性心脏病患者,其起源部位和心电图表现具有一定特征性,虽临床转归较好,但易反复发作,导管射频消融为这类心律失常提供了根治性方法.本文对来自浙江大学医学院附属第二医院2002年1月至2005年12月10例IVT患者的射频消融资料进行总结分析,现报道如下:     

导管射频消融治疗特发性室性心动过速的临床应用

目的评价射频消融治疗特发性室速的有效性和安全性.方法收集2002年1月至2005年1月期间在我院进行射频消融的特发性室性心动过速(IVT)患者34例,右室流出道特发性室速(IRVT)采用起搏标测确定消融耙点,左室特发性室速(ILVT)采用激动顺序标测和起搏标测相结合确定消融靶点.结果其中20例起源于左室间隔部和流出道,14例起源于右室流出道;31例即刻成功,3例失败,成功率91.2%.结论射频消融治疗特发性室性心动过速是安全和有效的.     

Carto指引下导管射频消融治疗特发性室性心动过速及室性早搏患者的临床疗效观察

目的探讨特发性室性心动过速及室性早搏患者在Carto指引下导管射频消融治疗的效果。方法纳入2008年6月—2016年7月期间到四川省攀枝花市中心医院行Carto指引下导管射频消融治疗的36例IVT及PVB患者为本次研究对象,所有患者均经Carto指引行导管射频消融进行治疗,观察此方法治疗特发性室性心动过速及室性早搏患者的治疗效果。结果 (1)临床基本情况:22例为单源性PVB,14例为IVT患者。(2)IVT及PVB起源位置:16例为流出道IVT及PVB,其中肺动脉瓣上1例,右心室流出道6例,主动脉窦内2例,左心室流出道6例;8例分支性左心室IVT及PVB患者,左前分支参与4例,左后分支参与6例;8例房室瓣周IVT及PVB患者,His束附近1例,二尖瓣环2例,三尖瓣环5例;2例心外膜IVT及PVB患者。(3)消融疗效及随访结果:消融成功率为94.44%,失败率为5.56%,1例复发者经再次消融成功,8例心律失常性心肌病患者的其中5例恢复正常,其余3例左心室扩大者范围逐渐缩小。结论 IVT及PVB患者常见的起源部位为左后间隔及流出道位置,且患者在Carto指引下进行导管射频消融治疗的疗效显著,其治疗方式是安全且有效的。

Idiopathic verapamil-sensitive left ventricular tachycardia complicated by right ventricular outflow tract ventricular tachycardia and ventricular fibrillation.

Idiopathic ventricular tachycardias (VTs) are generally divided into those arising from the right ventricle and those arising from the left ventricle. There has been few reports of two morphologically distinct VT occurring in patients with no apparent structural heart disease. We report a patient with verapamil-sensitive left VT with a right bundle branch block pattern that spontaneously changed to VT with a left bundle branch block pattern. Ventricular fibrillation was induced by the application of programmed stimulation. Although it is unclear if our patient with pleomorphic VT has ventricular vulnerability, it is necessary to investigate further and follow him carefully.     

Isolated left ventricular noncompaction mimicking ventricular mass

Isolated left ventricular noncompaction is an inherited cardiomyopathy characterized by multiple prominent trabeculations with deep intertrabecular recesses. The diagnosis is often missed because echocardiography poses inherent problems of poor echo window in assessment of the LV apex, which is most commonly involved in noncompaction. We report a case in which conventional 2D echocardiography failed to demonstrate multiple prominent trabeculations. Contrast echocardiography confirmed the presence of multiple trabeculations with deep intertrabecular recesses. This report emphasizes the importance of contrast echocardiography in the diagnosis of ventricular noncompaction.     

Congenital ventricular diverticulum associated with ventricular tachycardia

Congenital ventricular diverticula are rare. Clinically, they may be asymptomatic or cause systemic embolization, heart failure, valvular regurgitation, ventricular rupture, ventricular arrhythmia, or sudden death. We report the case of a 56-year-old woman with sustained ventricular tachycardia, who, during investigation, was diagnosed with a diverticulum in the inferobasal portion of the left ventricle. The clinical characteristics and treatment of this rare disease are discussed.
