Epicardial ablation of ventricular tachycardia associated with isolated ventricular noncompaction

A 52-year-old man presented with sudden onset of palpitations and dizziness. Echocardiogram confirmed the diagnosis of isolated noncompaction of ventricular myocardium with moderated systolic dysfunction, and the electrocardiogram (ECG) revealed ventricular tachycardia (VT), of which the focus seemed to match an area of prominent left ventricular noncompaction on the 12-lead surface ECG. Through the activation mapping from the endo- and epicardium, simultaneously, a discrete potential preceding the QRS during VT was observed at the anterolateral epicardial wall. He subsequently underwent radiofrequency ablation, and VT was successfully eliminated.     

Severe mitral regurgitation with right ventricular pacing, successfully treated with left ventricular pacing

A case of severe mitral regurgitation with refractory heart failure, after atrioventricular junction ablation and pacemaker implant, was solved with left ventricular pacing. Mitral regurgitation was related to a change in segmental left ventricular motion during right ventricular pacing.     

Arrhythmogenic right ventricular cardiomyopathy with left ventricular involvement and aortic dissection

Ten years ago, a 59-year-old patient presented with ventricular fibrillations. The resting ECG showed findings typical for ARVC. Echocardiography and ventriculography confirmed the diagnosis of ARVC showing a dilated right ventricle with aneurysms. MRI showed additional fatty replacement of the LV. Furthermore, the diagnosis of a chronic aortic dissection was established. Two years after ICD implantation, the patient died of progressive right heart failure. On autopsy, most of the RV and parts of the LV were replaced by fatty tissue, and the media of the aorta showed degenerative changes. A pathogenetic link between the two diseases remains speculative at this time.     

Late ventricular potentials in patients with cardiological X syndrome and their association with ventricular arrhythmias

The purpose of the study was to explore late ventricular potentials (LVPs) in patients with cardiological X syndrome (XS), their association with ventricular arrhythmias (VA), with the structure and function of the heart. Fifty-two patients were examined. A control group comprised 17 healthy individuals. LVPs were determined by recording a signal-averaged high resolution (AHR) ECG by means a Megacart-400 device ("Siemens"). It was shown that there was a relationship between LVPs and high-grade VA in patients with XS. The patients with the recorded LVPs were observed to have the enlarged left ventricle (LV) and a significant ST-segment depression during bicycle ergometric tests. Those with LVPs were ascertained to have a relationship between the end LV systolic volume and the values of a single of AHR ECG. At the same time, there was no correlation between the values of a single of AHR ECG and the magnitude of ST-segment depression.     

超声斑点追踪显像评价左心室心肌致密化不全患者心肌功能

目的 应用超声斑点追踪显像技术(STI)定量评价左心室心肌致密化不全(LVNC)患者左心室心肌纵向收缩功能,并探讨其在LVNC诊断中的价值。方法 LVNC患者21例,分为两组:LVNC-1组(n=10):LVEF≥50%;LVNC-2组(n=11):LVEF＜50%。以21名年龄性别相匹配的健康志愿者作为正常对照组。采集左心室心尖长轴动态图像,利用STI获取各节段心肌纵向应变(LS)曲线及收缩期峰值应变。结果 LVNC-2组左心室各水平LS均较正常对照组明显减低(P均＜0.05),LVEF、E’、E/E’与正常对照组比较差异有统计学意义(P均＜0.05)。LVNC-1组LS均较正常对照组减低(P均＜0.05),但其E’、E/E’与正常对照组无明显差异。取左心室心尖段LS均值－20.71%为界值,诊断LVNC患者左心室纵向收缩功能减低的敏感度和特异度为95.00%、100%;整体LS均值－17.90%为界值,其敏感度和特异度与LS相同。结论 应用超声STI技术可对LVNC患者左心室心肌功能进行深入定量评价。     

Advanced Anderson-Fabry disease presenting with left ventricular apical aneurysm and ventricular tachycardia

A 54-year-old female with Anderson-Fabry disease(AFD)-R342 Q missense mutation on exon 7 in alphagalactosidase A(GLA) gene- presented with sustained ventricular tachycardia. Imaging confirmed the presence of a new left ventricular apical aneurysm(LVAA) and a significantly reduced intra-cavitary gradient compared to two years prior. AFDcv is an X-linked lysosomal storage disorder caused by GLA enzyme deficiency. The phenotypic expression of AFD in the heart is not well described. Cardiac involvement can include left ventricular hypertrophy(LVH), which is typically symmetric, but can also mimic hypertrophic cardiomyopathy(HCM). Left ventricular apical aneurysm is a rare finding in HCM. We suggest a shared mechanism of LVAA formation in AFD and HCM, independent of the underlying cardiomyopathy. Mechanisms of LVAA formation in HCM include genetic predisposition and long-standing left ventricular wall stress from elevated intra-cavitary systolic pressures due to mid-cavitary obstruction. Both mechanisms are supported in this patient(a brother with AFD also developed a small LVAA). Screening for AFD should be considered in cases of unexplained LVH, particularly in patients with the aneurysmal variant of HCM.     

急性心肌梗死并室性心动过速/心室颤动的影响因素分析

目的:分析急性心肌梗死(acute myocardial infarction,AMI)患者并发室性心动过速(ventricular tachycardia,VT)/心室颤动(ventricular fibrillation,VF)的影响因素.方法:将安徽医科大学第一附属医院收治的453例AMI患者分为VT/VF组和无VT/VF组,对两组进行比较分析发生VT/VF的影响因素.结果:单因素分析示,VT/VF组与无VT/VF组在诸多方面差异有显著性.经多因素Logistic回归分析显示,高级别的Killip分级、血钾离子水平异常以及广泛前壁心肌梗死是影响患者发生VT/VF的独立危险因素,β-受体阻滞剂是保护因素.结论:VT/VF是AMI患者的严重并发症,高级别的Killip分级、血钾水平异常以及广泛前壁心肌梗死是影响患者发生VT/VF的独立危险因素,而β-受体阻滞剂是保护因素.
