Optimizing remote heart failure management: First experiences with the HeartInsight score for implanted defibrillators.

We explored the results of two tests of the novel HeartInsight algorithm for heart failure (HF) prediction, reconstructing trends from historical cases. Results suggest potential extension of HeartInsight to implantable cardioverter defibrillators patients without history of HF and illustrate the importance of the baseline clinical profile in enhancing algorithm specificity.

[e-Health, telemedicine and applications in cardiology: state of the art in Italy and experience of the cardiology unit of the G.B. Grassi Hospital of Rome]. / e-Health, telemedicina e applicazioni in Cardiologia: stato dell'arte in Italia ed esperienza dell'U.O.C. di Cardiologia dell'Ospedale G.B. Grassi di Roma.

e-Health (electronic health) refers to the use of information and communication technologies (ICT) to promote organizational change and facilitate new healthcare skills. In the last few years, several telemedicine services using ICT have been launched and the updating of related regulations has started, also for the increase in demand for services, their complexity and the need to offer adequate care to the patient. In cardiology, the experiences concern mainly patients suffering from heart failure or the carriers of cardiac implantable electronic devices (CIEDs), and few experiences are described in ischemic heart disease. In this article we present the design, the implementation and the results of the telemedicine service at the Cardiology Unit of the G.B. Grassi Hospital in Rome, concerning follow-up televisits for patients with heart failure, ischemic heart disease and for management of treatment plans, telemonitoring and telecontrol of CIEDs carriers and teleconsultation in ischemic heart disease. The considerations of this review, the experiences reported and the speed of digital evolution make the implementation of existing practices and the redesign of new pathways necessary.

Preliminary experience with a novel Multisensor algorithm for heart failure monitoring: The HeartLogic index.

We report the first case of a patient in whom an implantable cardioverter-defibrillator (ICD) endowed with HeartLogic, a novel algorithm for heart failure (HF) monitoring, was implanted in clinical practice. The good temporal association between HeartLogic index threshold crossings and HF hospitalizations confirms the high sensitivity in detecting gradual worsening of HF.

[Electromagnetic interference in the current era of cardiac implantable electronic devices designed for magnetic resonance environment]. / Le interferenze elettromagnetiche nell'era dei dispositivi elettronici cardiaci impiantabili compatibili con la risonanza magnetica.

In the last decades we are observing a continuous increase in the number of patients wearing cardiac implantable electronic devices (CIEDs). At the same time, we face daily with a domestic and public environment featured more and more by the presence and the utilization of new emitters and finally, more medical procedures are based on electromagnetic fields as well. Therefore, the topic of the interaction of devices with electromagnetic interference (EMI) is increasingly a real and actual problem.In the medical environment most attention is paid to magnetic resonance, nevertheless the risk of interaction is present also with ionizing radiation, electrical nerve stimulation and electrosurgery. In the non-medical environment, most studies reported in the literature focused on mobile phones, metal detectors, as well as on headphones or digital players as potential EMI sources, but many other instruments and tools may be intentional or non-intentional sources of electromagnetic fields.CIED manufacturers are more and more focusing on new technological features in order to make implantable devices less susceptible to EMI. However, patients and emitter manufacturers should be aware that limitations exist and that there is not complete immunity to EMI.

Permanent pacing lead insertion through the cephalic vein using an hydrophilic guidewire.

The cephalic vein (CV) should be preferred to the subclavian vein for the insertion of permanent pacing leads because of better results. Unfortunately, the direct lead introduction using the standard CV cutdown is often unsuccessful. This study evaluated the efficacy and safety of a steerable hydrophilic guidewire (HGW) for lead insertion through the CV. An HGW was successfully introduced through the cephalic vein and into the subclavian vein. Over a 6-month period, 115 consecutive patients underwent pacemaker implantation. In nine (7.8%) patients, the cephalic vein did not allow lead or guidewire introduction. The direct introduction of the leads through the CV was successful in 55 (51.9%) of 106 patients. In 14 (12.2%) additional patients, a lead was inserted through the CV using a standard guidewire. The use of an HGW and of a split introducer allowed successful insertion of at least one lead in 35 (30.4%) additional patients. Overall, the HGW was successful in 35 (94.6%) of 37 of patients in which the technique was attempted. The CV approach was successful in 104 (90.4%) of 115 patients. In conclusion, the use of an HGW allows the insertion of a pacing lead through the CV in the great majority of patients in whom direct introduction and the use of a standard guidewire had failed. The technique significantly improves the success rate of the CV approach and may help to improve the acute and long-term results of permanent cardiac pacing.
