    BACKGROUND: Left ventricular diastolic dysfunction, with secondary atrial pressure elevation, is a well-known concept. On the contrary, effect of left atrial compliance on pulmonary pressure is rarely considered. CASE PRESENTATION: We report the echocardiographic case of a 9-year-old child who presented severe rheumatic mitral valve regurgitation with a giant left atrium, in contrast to a normal artery pulmonary pressure, testifying of the high left atrial compliance. CONCLUSION: Left atrial compliance is an important determinant of symptoms and pulmonary artery pressure in mitral valve disease

    SummaryFocused cardiac ultrasound (FCU) has emerged in recent years and has created new possibilities in the clinical assessment of patients both in and out of hospital. The increasing portability of echocardiographic devices, with some now only the size of a smartphone, has widened the spectrum of potential indications and users, from the senior cardiologist to the medical student. However, many issues still need to be addressed, especially the acknowledgment of the advantages and limitations of using such devices for FCU, and the extent of training required in this rapidly evolving field. In recent years, an increasing number of studies involving FCU have been published with variable results. This review outlines the evidence for the use of FCU with pocket-echo to address specific questions in daily clinical practice

    Aims: The recent availability of the novel oral anticoagulants (NOACs) may have led to a change in the anticoagulation regimens of patients referred to catheter ablation of atrial fibrillation (AF). Preliminary data exist concerning dabigatran, but information regarding the safety and efficacy of rivaroxaban in this setting is currently scarce. Methods: and results Of the 556 consecutive eligible patients (age 61.0 ± 9.6; 74.6% men; 61.2% paroxysmal AF) undergoing AF catheter ablation in our centre (October 2012 to September 2013) and enroled in a systematic standardized 30-day follow-up period: 192 patients were under vitamin K antagonists (VKAs), 188 under rivaroxaban, and 176 under dabigatran. Peri-procedural mortality and significant systemic or pulmonary thromboembolism (efficacy outcome), as well as bleeding events (safety outcome) during the 30 days following the ablation were evaluated according to anticoagulation regimen. During a 12-month time interval, the use of the NOACs in this population rose from <10 to 70%. Overall, the rate of events was low with no significant differences regarding: thrombo-embolic events in 1.3% (VKA 2.1%; rivaroxaban 1.1%; dabigatran 0.6%; P = 0.410); major bleeding in 2.3% (VKA 4.2%; rivaroxaban 1.6%; dabigatran 1.1%; P = 0.112), and minor bleeding 1.4% (VKA 2.1%; rivaroxaban 1.6%; dabigatran 0.6%; P = 0.464). No fatal events were observed. Conclusion: The use of the NOAC in patients undergoing catheter ablation of AF has rapidly evolved (seven-fold) over 1 year. These preliminary data suggest that rivaroxaban and dabigatran in the setting of catheter ablation of AF are efficient and safe, compared with the traditional VKA

    Major gaps in the information provided to patients before implantation of cardioverter defibrillators: a prospective patient European evaluation

    AIMS: Information provided to patients prior to implantable cardioverter-defibrillator (ICD) insertion and their participation in the decision-making process are crucial for understanding ICD function and accepting this lifelong therapy. The aim of this study is to evaluate the extent to which different aspects related to ICD and quality of life were transmitted to patients prior to ICD implantation. METHODS AND RESULTS: Prospective, multicenter European study with an online questionnaire initiated by the European Heart Rhythm Association. The questionnaire was filled-in directly and personally by the ICD patients who were invited to participate. A total of 1809 patients (majority in their 40s-70s, with 624 women, 34.5%) from 10 European countries participated in the study. The median time from first ICD implantation was 5 years (interquartile range 2-10). Overall, 1155 patients (71.5%) felt optimally informed at the time of device implantation, however many respondents received no information about ICD-related complications (n = 801, 49.6%), driving restrictions (n = 718, 44.5%), and possibility of end-of-life ICD deactivation (n = 408, 25.4%). Of note, women were less frequently involved in the decision-making process than men (47.3% vs. 55.9%, P = 0.003) and reported to be less often optimally informed before ICD implantation than men (61.2% vs. 76.8%, P < 0.001). More women mentioned the desire to have learned more about ICD therapy and the benefit/risk balance (45.4% vs. 33.7% of men; P < 0.001). CONCLUSIONS: This patient-based evaluation provides alarming findings on the lack of information provided to patients prior ICD implantation, particularly for women

    0432: Impact of early complications on outcomes among patients with implantable cardioverter defibrillator in primary prevention

    Get PDF
    BackgroundThe life-saving benefit of implantable cardioverter defibrillators (ICD) has been well demonstrated, and therefore their utilization has considerably grown in the last 10 years. At the same time, complications have become an increasingly important concern.ObjectivesThis study aimed to assess the prevalence and impact on outcomes (late complications and overall mortality) of early complications after ICD implantation for primary prevention in a large French population.MethodsFrom a multicentric French registry (DAI-PP Registry, 2002-2012), 5547 consecutive patients, with coronary artery disease or dilated cardiomyopathy, were implanted with an ICD in the setting of primary prevention. From 5338 (96%) patients with full information, we determined prevalence, independent associated factors and prognosis of the occurrence of early (within 30 days post implantation) complications.ResultsEarly complications occurred in 709 patients (13.5%), mainly related to lead dysfunction or hematoma (56%). Independent associated factors to early complications were renla impairment (clearance <30ml/min, OR=1.69, 95% CI 1.19-2.41, P<0.001), cardiac resynchronization therapy (OR=1.61, 95% CI 1.17-2.21, P=0.004), anticoagulant therapy (OR=1.30, 95% CI 1.04-1.63, P=0.02) and older age (OR=1.02, 95% CI 1.01-1.02, P=0.03). During a mean follow-up of 3.1±2.3 years, 834 patients experienced ≥1 complication (15.6%), mainly inappropriate therapies and/or lead dysfunction (75%). After consideration of potential confounding factors, early complications were significantly associated with the occurrence of late complications (OR=2.15, 95% CI 1.73-2.66, P<0.0001) and a higher risk of overall mortality (OR=1.48, 95% CI 1.17-1.88, P=0.001).ConclusionsEarly complication is a frequent event after ICD implantation occurring in one out of six patients. These events are associated with a significant increase of late complications and overall mortality

    Regional disparity on patient characteristics and perceptions after implantable cardioverter-defibrillator implantation: results from an EHRA patient survey

    AIMS: The aim of this study was to identify potential regional disparities in characteristics of implantable cardioverter-defibrillator (ICD) recipients, patient perceptions and perspectives after implantation and level of information provided to patients. METHODS AND RESULTS: The prospective, multicentre, and multinational European Heart Rhythm Association patient Survey 'Living with an ICD' included patients already implanted with an ICD (median ICD dwell time - 5 years, interquartile range 2-10). An online questionnaire was filled-in by patients invited from 10 European countries. A total of 1809 patients (the majority in their 40s to 70s, 65.5% men) were enrolled, with 877 (48.5%) from Western Europe (group 1), followed by 563 from Central/Eastern Europe (group 2, 31.1%), and 369 from Southern Europe (group 3, 20.4%). A total of 52.9% of Central/Eastern Europe patients reported increased satisfaction after ICD placement compared with 46.6% from Western and 33.1% from Southern Europe (1 vs. 2 P = 0.047, 1 vs. 3 P < 0.001, 2 vs. 3 P < 0.001). About 79.2% of Central/Eastern and 76.0% of Southern Europe patients felt optimally informed at the time of device implantation compared with just 64.6% from Western Europe (1 vs. 2 P < 0.001, 1 vs. 3 P < 0.001, 2 vs. 3 P = ns). CONCLUSIONS: While physicians in Southern Europe should address the patients' concerns about the impact of the ICD on quality of life, physicians from Western Europe should focus on improving the quality of information provided to their prospective ICD patients. Novel strategies to address regional differences in patients' quality of life and provision of information are warranted
