We sought to assess the relation between time from myocardial infarction (MI) to enrolment and patient outcomes and to examine the association between these outcomes and implantable cardioverter defibrillator (ICD) therapy. ⋯ The risk of arrhythmic death or cardiac arrest and all-cause death did not vary as a function of time from the most recent MI to enrolment. Inducibility by an EPS was associated with worse outcomes only in patients with an MI

Atrial fibrillation (AF) ablation efficacy varies according to patients' clinical characteristics. Although the association of obstructive sleep apnoea (OSA) and AF is well established, data on AF ablation efficacy in OSA are scarce. The aim of this study was to clarify the effect of OSA on the outcome of AF ablation. ⋯ In patients with AF ablation, the presence of severe OSA is an independent predictor for AF ablation failure.

A 71-year-old female patient was referred for catheter ablation of drug-refractory, symptomatic atrial fibrillation. Initial intracardiac echocardiography (ICE) incidentally showed a mobile embolus stuck at a bifurcation of the right pulmonary artery. The procedure was suspended and the finding was subsequently confirmed by computed tomography pulmonary angiography. This case illustrates a potential value of real-time imaging by ICE during invasive procedures.

The usefulness of cardiac resynchronization therapy (CRT) in patients with congestive heart failure is offset by its long, user-dependent, and technical procedure. No studies have been published regarding factors related to CRT implantation procedure duration and X-ray exposure. Additionally, only a few studies have investigated the predictive factors of primary left ventricular (LV) lead implant failure. The aim of this prospective study was two-fold: (i) to evaluate the prevalence and predictive factors of prolonged CRT implantation procedure and (ii) to identify the predictive factors of primary LV lead implantation failure. ⋯ In this study, the rate of difficult CRT device implantation procedures approached 25%. Both the degree of LV dysfunction and the operator's experience were independent predictors of surgical difficulties. Left ventricular end-systolic volume was the only independent predictor of primary LV lead implant failure.

This survey assesses the current opinion on and practice of the management of terminally ill patients with implanted cardioverter-defibrillators (ICDs) in 47 large European centres. The principal findings of this survey were that most physicians (62%) from European centres who responded to this survey would consider deactivating ICDs at the patient's end of life. ⋯ Practices of deactivating procedure differ and approach to standardized clinical scenarios is inhomogeneous. Patients are provided with surprisingly little information on the possibility of deactivation of ICDs since this subject is only actively discussed in 4% of centres.
