PCI techniques to aid implantation of CRT-D in a senior patient with persistent left superior vena cava

Journal of Geriatric Cardiology 2016年第7期13卷 639-642页

作者： Qiang WU Sha YU Ya-Ping AN Bao-Lin CHEN Department of Cardiology Guizhou Provincial People's Hospital Guiyang Guizhou China

Persistent left superior vena cava (PLSVC) is a rare congenital anomaly of the vena cava, affecting about 0.5% of the general population, which poses a particular obstacle during transvenous electronic device implantation. Here, we report a successful cardiac resynchronization therapy-de-fibrillator device (CRT-D) implantation strategy in which techniques and devices for percutaneous coronary intervention were used via a PLSVC.

Reversal of Wolff-Parkinson-White Syndrome induced dilated cardiomyopathy via resynchronization and subsequent accessory pathway ablation

引用

Journal of Geriatric Cardiology 2017年第10期14卷 654-656页

Recurrent or incessant tachycardia is frequently found in symptomatic Wolff-Parkinson-White (WPW) syndrome, leading to ventricular dysfunction, dilated cardiomyopathy (DCM) and heart failure in infants and children. Recently, Winter, et al. report that WPW syndrome could provoke many kinds of cardiac dysfunction, leading to remodeling and progressive ventricular dilatation through pre-excitation-related dyssynchrony, even without arrhythmia. Asymptomatic WPW syndrome-induced DCM has rarely been reported, with incidence rates higher in pediatric patients than in adults. However, the pathogenesis of asymptomatic WPW syndrome-induced DCM remains unclear. Here, we present a case of an adult patient with DCM associated with asymptomatic free wall accessory pathway (AP), who received cardiac function improvement both after pacemaker implantation and radiofrequency ablation.

Cardiac resynchronization therapy improved the clinical outcomes in pacemaker patients upgraded to biventricular device

Journal of Geriatric Cardiology 2017年第10期14卷 649-651页

作者： Han JIN Wei HUA Li-Gang DING Jing WANG Hong-Xia NIU Min GU Cong XUE Shu ZHANG The Cardiac Arrhythmia Center Fuwai Hospital Chinese Academy of Medical Sciences and Peking Union Medical College Beijing China

The right ventricular pacing (RVP) is the standard treatment for patients with severe bradyarrhythmias; however, it may cause and exacerbate heart failure symptoms in a long run under some circumstances. In fact, significant left ventricular (LV) systolic dysfunction and symptomatic heart failure (HF) is commonly found in patient population with pacemaker implantations.

Cardiac magnetic resonance imaging:Which information is useful for the arrhythmologist?

引用

World Journal of Cardiology 2017年第10期9卷 773-786页

作者： Elia De Maria Annachiara Aldrovandi Ambra Borghi Letizia Modonesi Stefano Cappelli Cardiology Unit Ramazzini Hospital41012 Carpi(Modena)Italy

Cardiac magnetic resonance(CMR) is a non-invasive,nonionizing,diagnostic technique that uses magnetic fields,radio waves and field gradients to generate images with high spatial and temporal resolution.After administration of contrast media(e.g.,gadolinium chelate),it is also possible to acquire late images,which make possible the identification and quantification of myocardial areas with scar/fibrosis(late gadolinium enhancement,LGE).CMR is currently a useful instrument in clinical cardiovascular practice for the assessment of several pathological conditions,including ischemic and nonischemic cardiomyopathies and congenital heart disease.In recent years,its field of application has also extended to arrhythmology,both in diagnostic and prognostic evaluation of arrhythmic risk and in therapeutic decisionmaking.In this review,we discuss the possible useful applications of CMR for the arrhythmologist.It is possible to identify three main fields of application of CMR in this context:(1) arrhythmic and sudden cardiac death risk stratification in different heart diseases;(2) decisionmaking in cardiac resynchronization therapy device implantation,presence and extent of myocardial fibrosis for left ventricular lead placement and cardiac venous anatomy; and(3) substrate identification for guiding ablation of complex arrhythmias(atrial fibrillation and ventricular tachycardias).
