    IntroductionPulmonary embolism (PE) is a relatively common cardiovascular emergency. PE is a difficult diagnosis that may be missed because of non-specific clinical presentation. Non invasive investigations are compulsory to confirm PE. The management of PE is now well codified especially massive PE.Observations2 women aged respectively of 28 and 34 years, hospitalized in our hospital for massive pulmonary embolism with poor hemodynamic state. For the first patient the diagnosis is confirmed by TTE showing thrombus in the right atrium and left pulmonary artery and by computed tomography angiography. The two patients received thrombolytic treatment by recombinant tissue plasminogen activator (rtPA) with favorable outcome.ConclusionThrombolytic therapy is the first-line treatment in patients with high-risk PE presenting with cardiogenic shock and/or persistent arterial hypotension, with very few absolute contraindications

    IntroductionAcute pulmonary embolism (PE) remains a life-threatening disease and one of three major disease entities with chest discomfort seen in the emergency room. Despite progress in imaging techniques and knowledge of this disease, its medical diagnosis is one of the most difficult to achieve. The clinical assessment of PE probability remains central to the diagnosis and evaluation. Presently, accepted diagnostic modalities for the confirmation of PE include V/Q scanning, chest CT, and standard angiography. All approaches have limitations. Because echocardiography is noninvasive, provides rapid bedside results. It is an attractive imaging modality to diagnose PE.PurposeThe purpose of this study is to assess the contribution of transthoracic echocardiography (TTE) in the clinical setting of PE.ResultsEighteen patients were included. There were 7 men and 11 women. The mean age was 57 years [28; 80]. TTE was performed in all patients within the first 24 to 72 hours of admission. The diagnosis of PE was confirmed by standard angiography in all cases. Tricuspid regurgitation was the most common TTE finding (16 of 18), followed by dilated right ventricle (15 of 18), pulmonary hypertension (11 of 18), paradoxical interventricular septal motion (7 of 18) and right ventricular hypokinesis (2 of 18). TTE revealed thrombi inside the right-sided heart cavities in 3 patients. The thrombus was detected at the apex of the right ventricle in the first case, at the right atria in the second case and many thrombi were objectified even at the right atria and ventricle, at the inferior vena cava and at the left pulmonary artery in the third case.ConclusionTransthoracic echocardiography may reveal findings that strongly support hemodynamically significant PE. In the majority of cases TTE provides only indirect signs of PE. It could, though, far less frequently visualise thromboembolic material inside the right-sided heart cavities. Direct visualisation of the thrombus, although confirming PE, remains an exceptional finding. This may be useful for prompt decision making in patients with haemodynamic compromise considered for thrombolysis or embolectomy

    Epidemiology of heart failure and long-term follow-up outcomes in a north-African population: Results from the NAtional TUnisian REgistry of Heart Failure (NATURE-HF)

    International audienceThe NATURE-HF registry was aimed to describe clinical epidemiology and 1-year outcomes of outpatients and inpatients with heart failure (HF). This is a prospective, multicenter, observational survey conducted in Tunisian Cardiology centers. A total of 2040 patients were included in the study. Of these, 1632 (80%) were outpatients with chronic HF (CHF). The mean hospital stay was 8.7 ± 8.2 days. The mortality rate during the initial hospitalization event for AHF was 7.4%. The all-cause 1-year mortality rate was 22.8% among AHF patients and 10.6% among CHF patients. Among CHF patients, the older age, diabetes, anemia, reduced EF, ischemic etiology, residual congestion and the absence of ACEI/ ARBs treatment were independent predictors of 1-year cumulative rates of rehospitalization and mortality. The female sex and the functional status were independent predictors of 1-year all-cause mortality and rehospitalization in AHF patients. This study confirmed that acute HF is still associated with a poor prognosis, while the mid-term outcomes in patients with chronic HF seems to be improved. Some differences across countries may be due to different clinical characteristics and differences in healthcare systems

    Design and Rationale of the National Tunisian Registry of Heart Failure (NATURE-HF): Protocol for a Multicenter Registry Study

    BackgroundThe frequency of heart failure (HF) in Tunisia is on the rise and has now become a public health concern. This is mainly due to an aging Tunisian population (Tunisia has one of the oldest populations in Africa as well as the highest life expectancy in the continent) and an increase in coronary artery disease and hypertension. However, no extensive data are available on demographic characteristics, prognosis, and quality of care of patients with HF in Tunisia (nor in North Africa). ObjectiveThe aim of this study was to analyze, follow, and evaluate patients with HF in a large nation-wide multicenter trial. MethodsA total of 1700 patients with HF diagnosed by the investigator will be included in the National Tunisian Registry of Heart Failure study (NATURE-HF). Patients must visit the cardiology clinic 1, 3, and 12 months after study inclusion. This follow-up is provided by the investigator. All data are collected via the DACIMA Clinical Suite web interface. ResultsAt the end of the study, we will note the occurrence of cardiovascular death (sudden death, coronary artery disease, refractory HF, stroke), death from any cause (cardiovascular and noncardiovascular), and the occurrence of a rehospitalization episode for an HF relapse during the follow-up period. Based on these data, we will evaluate the demographic characteristics of the study patients, the characteristics of pathological antecedents, and symptomatic and clinical features of HF. In addition, we will report the paraclinical examination findings such as the laboratory standard parameters and brain natriuretic peptides, electrocardiogram or 24-hour Holter monitoring, echocardiography, and coronarography. We will also provide a description of the therapeutic environment and therapeutic changes that occur during the 1-year follow-up of patients, adverse events following medical treatment and intervention during the 3- and 12-month follow-up, the evaluation of left ventricular ejection fraction during the 3- and 12-month follow-up, the overall rate of rehospitalization over the 1-year follow-up for an HF relapse, and the rate of rehospitalization during the first 3 months after inclusion into the study. ConclusionsThe NATURE-HF study will fill a significant gap in the dynamic landscape of HF care and research. It will provide unique and necessary data on the management and outcomes of patients with HF. This study will yield the largest contemporary longitudinal cohort of patients with HF in Tunisia.
