We report the successful minimally invasive placement of a pericardial implantable cardioverter-defibrillator (ICD) in a 16-kg child. A transvenous ICD dual coil was advanced through a small subxiphoid incision and screwed into the oblique sinus pericardium under fluoroscopic guidance. An additional sense-pace lead was sutured onto the right ventricular apex, and the generator was placed in the upper abdominal wall through the same incision. Threshold testing demonstrated successful defibrillation at 15 J...

We report the case of a man in his 60s who had dilated cardiomyopathy with severe functional mitral regurgitation. Four years after a cardiac resynchronization therapy (CRT) device with an implantable cardioverter defibrillator was implanted, this device was replaced with an adaptive CRT device because of battery consumption. Seven months after replacement of this device, the left ventricular pacing to right ventricular activation and the atrioventricular delay from automatic adjustments contributed to less functional mitral regurgitation...

A 76-year-old man who had been diagnosed with long-QT syndrome type 2 had frequent syncopal attacks. The electrocardiogram was monitored, and frequent torsades de pointes (TdP) was detected despite administration of conventional medications: oral propranolol, verapamil, intravenous magnesium sulfate, verapamil, and lidocaine. In contrast, 2 μg/kg/min landiolol could completely suppress TdP. Subsequently, an implantable cardioverter defibrillator was placed, and he was diagnosed with silent myocardial ischemia using myocardial perfusion scintigraphy and coronary angiography...

REVIEW
Hisashi Yokoshiki, Hirofumi Mitsuyama, Masaya Watanabe, Takeshi Mitsuhashi, Akihiko Shimizu
Cardiac resynchronization therapy (CRT) using a biventricular pacing system has been an effective therapeutic strategy in patients with symptomatic heart failure with a reduced left ventricular ejection fraction (LVEF) of 35% or less and a QRS duration of 130 ms or more. The etiology of heart failure can be classified as either ischemic or non-ischemic cardiomyopathy. Ischemic etiology of patients receiving CRT is prevalent predominantly in North America, moderately in Europe, and less so in Japan. CRT reduces mortality similarly in both ischemic and non-ischemic cardiomyopathy, whereas reverse structural left ventricular remodeling occurs more favorably in non-ischemic cardiomyopathy...

The number of patients treated with cardiac implantable electronic devices (CIED) is continously increasing. Knowledge of the medical indications and technical mode of functioning of these devices is a basic prerequisite for the safe perioperative care of this patient cohort. The CIEDs are subjected to a multitude of disturbing influences in the perioperative setting. This can result in potentially dangerous complications, such as exit block and oversensing. The safe performance of interventions is possible as long as some basic rules are followed...

Ventricular tachycardia (VT), often degenerating into ventricular fibrillation, is the leading cause of sudden cardiac death. Catheter ablation of VT is associated with relatively low, long-term success rates, while the optimal timing of ablation in patients with ischaemic and non-ischaemic cardiomyopathy remains unclear. Contemporary practice in most centres is to consider ablation late in the disease process following the failure of anti-arrhythmic medications and/or following recurrent implantable cardioverter-defibrillator shocks...

Recurrent episodes of ventricular tachycardia in patients with structural heart disease are associated with increased mortality and morbidity, despite the life-saving benefits of implantable cardiac defibrillators. Reducing implantable cardiac defibrillator therapies is important, as recurrent shocks can cause increased myocardial damage and stunning, despite the conversion of ventricular tachycardia/ventricular fibrillation. Catheter ablation has emerged as a potential therapeutic option either for primary or secondary prevention of these arrhythmias, particularly in post-myocardial infarction cases where the substrate is well defined...

BACKGROUND: Hypertrophic cardiomyopathy is the most common type of cardiomyopathy, but many patients lack sarcomeric/myofilament mutations. We studied whether cardio-specific α-galactosidase A gene variants are misinterpreted as hypertrophic cardiomyopathy because of the lack of extracardiac organ involvement. METHODS AND RESULTS: All subjects who tested positive for the N215S genotype (n=26, 13 females, mean age 49±17 [range, 14-74] years) were characterized in this prospective monocentric longitudinal cohort study to determine genotype-specific clinical characteristics of the N215S (c...

BACKGROUND: Magnetic resonance imaging (MRI) has been performed safely in patients without MRI-conditional cardiac implantable electronic devices (CIED), but experience specifically with cardiac magnetic resonance imaging (CMR) is limited in this patient population. OBJECTIVE: Evaluate the safety of CMR in non-MRI-conditional CIED and the interpretability of images using wideband sequences. METHODS: We performed 114 consecutive CMR studies in 111 patients (mean age 59±14 years with 12 pacemakers, 73 implantable cardioverter defibrillators, 29 biventricular defibrillators) utilizing a wideband pulse sequence for late gadolinium enhancement (LGE) imaging...

It's necessary to interrupt cardiopulmonary resuscitation (CPR) for a reliable automatic external defibrillator (AED) rhythm analysis, because the mechanical activity from the chest compressions introduces artifacts in the electrocardiogram (ECG) that substantially lower the capacity of an AED to judge cardio-electric rhythm. However, repeated interruptions of compression will reduce the quality of CPR, which in turn affect the prognosis of patients with cardiac arrest (CA). In order to improve the quality of CPR, reduce the interruptions of chest compression and implement accurate defibrillation, people have made many efforts on identifying ECG rhythm in CPR...
