Complete atrioventricular block is a relatively uncommon arrhythmia that is nonetheless increasingly seen in elderly people of developed countries, due to the increase in life expectancy. Congenital and degenerative etiologies are the most commonly seen among young and old patients, respectively. However, scientific literature is surprisingly scarce regarding the etiology of complete atrioventricular block in the asymptomatic otherwise healthy young and middle-aged adult population. Coronary artery disease, autoimmune disorders such as systemic lupus erythematosus or rheumatoid arthritis, history of acute or chronic infectious or hypersensitivity myocarditis, infiltrative processes, hypothyroidism, congenital cardiopathies such as left ventricular noncompaction or Ebstein anomaly, lamin A/C mutations, and pathologic hypervagotony and idiopathic degenerative scleroatrophy of the atrioventricular junctional specialized tissue (Lenegre-Lev disease) are among the most frequent etiologies of complete atrioventricular block in young or middle-aged adults. To our knowledge, no comprehensive review on the specificities of the investigation warranted in this age group has ever been developed, nor have the implications of particular diagnoses on treatment modalities been appropriately addressed. We aim at reviewing the most frequent differential diagnoses of advanced atrioventricular block in otherwise healthy asymptomatic or mildly symptomatic young or middle-aged adults and their impact on therapeutic options. Additionally, we suggest a diagnostic algorithm that may be helpful in this group of patients. (PACE 2012; 35:1395-1405) complete atrioventricular block, atrioventricular block etiology, cardiac conduction Introduction Complete heart block, also referred to as third-degree heart block or third-degree atrioventricular (AV) block, is a disorder of the cardiac conduction system where there is complete dissociation of the atrial and ventricular activity due to the absence of conduction through the atrioventricular node (AVN) or His-Purkinje system. Although Mobitz I second-degree AV block is observed in 1-2% of healthy young people, especially during sleep, the prevalence of third-degree AV block is only 0.02% in the United States and 0.04% worldwide. 1,2 Its incidence increases with advancing age (highest in people older than 70 years), despite an early peak in infancy and early childhood due to congenital

Implantable cardioverter-defibrillator (ICD) may impact patients’ life significantly. The aim of this survey was to analyse the impact of the ICD on quality of life (QoL) metrics from the patient’s perspective. ‘Living with an ICD’ was a prospective, multicentre study with an online questionnaire submitted to the European Heart Rhythm Association (EHRA) Research Network centres as well as patient associations from 10 European countries; it was filled-in directly and personally by the patients that were invited to participate, with a minimal interaction or influence from the healthcare professionals. Overall, the questionnaire was completed by 1809 patients (624 women, 34.5%). Patients in their 60s and 70s and from Western Europe were the most represented. The median time from first ICD implantation was 5 years (IQR 2–10). Device-related complications were reported by 505 patients (22.4%), including one or more inappropriate shocks (n = 209, 11.6%). Almost half the respondents reported improved QoL, with a more favourable impact for those receiving cardiac resynchronization therapy-defibrillator (CRT-D), and only a 10th experienced a significant decrease in QoL. The occurrence of complications remained a major predictor of deteriorated QoL (odds ratio 2.1, 95% confidence interval 1.4–3.0, P < 0.001). In conclusion, most patients have a globally positive view and acceptance of ICD therapy, reporting preserved to improved QoL after device implantation. Complications, namely inappropriate shocks, affect the expectation of living a normal life post-implant and are associated with a significant decrease in QoL. Our findings also highlight the importance of a detailed informed consent process and the involvement of the patient in the decision-making process.

CA eliminates VT in a large proportion of patients long term. Ablation strategy did not impact outcome and hence substrate ablation is a reasonable initial strategy. Non-inducibility of VA predicted survival free from VA and may be worth pursuing as a procedural end-point.

-Gemella morbillorum, a commensal of the oropharynx, upper respiratory, urogenital and gastrointestinal tract is rarely associated with infections in humans. However, an increasing number of infectious processes in different locations have been reported. Cerebral abscesses caused by these bacteria are extremely uncommon with only four cases previously described in the literature. We present the case of a cerebellar abscess by Gemella morbillorum in a 50 years-old man with inter-atrial communication dealt by surgical excision and antimicrobial therapy.KEY WORDS: cerebellar abscess, inter-atrial communication, Gemella. Abscesso cerebelar por Gemella morbillorum em paciente com comunicação inter-atrialRESUMO -Gemella morbillorum, uma bactéria comensal da orofaringe, vias aéreas superiores e aparelhos urogenital e gastrointestinal, raramente causa infecções em humanos. No entanto, um crescente número de processos infeciosos em diferentes localizações tem sido referido. Abcessos cerebrais provocados por esta bactéria são extremamente raros, encontrando-se apenas quatro casos previamente descritos na literatura.

Athletes with cardiac disorders frequently pose an ethical and medical dilemma to physicians assessing their eligibility to participate in sport. In recent decades, patient empowerment has been gaining increasing recognition in clinical decision-making. Empowerment is a process through which people are involved over the decisions and actions that affect their own lives. In the context of a cardiac disorder, empowerment means giving an athlete the chance to participate in the decision about whether or not to remain active in competition. Three models of treatment decision-making are described in this paper, with progressive levels of empowerment: the paternalistic model (the athlete has a passive role), the shared-decision making model (both athlete and physician participate in the decision) and the informeddecision making (the decision is made by the athlete while the role of the physician is solely to provide information). This paper critically discusses the issues involved in disqualification of athletes with cardiovascular disorders and suggests possible ways of incorporating patient empowerment in potentially career-ending decisions. The authors propose a model of empowerment, which gives patients the opportunity to choose how much, and if, they would like to be involved in the decision-making process.
