Contemporary management of patients with atrial fibrillation in the Netherlands and Belgium: a report from the EORP-AF long-term general registry.

BACKGROUND: Contemporary data regarding the characteristics, treatment and outcomes of patients with atrial fibrillation (AF) are needed. We aimed to assess these data and guideline adherence in the EURObservational Research Programme on Atrial Fibrillation (EORP-AF) long-term general registry. METHODS: We analysed 967 patients from the EORP-AF long-term general registry included in the Netherlands and Belgium from 2013 to 2016. Baseline and 1­year follow-up data were gathered. RESULTS: At baseline, 887 patients (92%) received anticoagulant treatment. In 88 (10%) of these patients, no indication for chronic anticoagulant treatment was present. A rhythm intervention was performed or planned in 52 of these patients, meaning that the remaining 36 (41%) were anticoagulated without indication. Forty patients were not anticoagulated, even though they had an indication for chronic anticoagulation. Additionally, 63 of the 371 patients (17%) treated with a non-vitamin K antagonist oral anticoagulant (NOAC) were incorrectly dosed. In total, 50 patients (5%) were overtreated and 89 patients (9%) were undertreated. However, the occurrence of major adverse cardiac and cerebrovascular events (MACCE) was still low with 4.2% (37 patients). CONCLUSIONS: Overtreatment and undertreatment with anticoagulants are still observable in 14% of this contemporary, West-European AF population. Still, MACCE occurred in only 4% of the patients after 1 year of follow-up.

[Isolated pulmonary valve endocarditis: a case report]. / Endocardite valvulaire pulmonaire isolée. A propos d'un cas.

The authors report the very rare case of isolated pulmonary valve endocarditis in the absence of classical predisposing factors and discuss the therapeutic approach. In the absence of large series, a maximum of information is developed from this new case, especially with respect to its unusual context.

U wave alternans in severe ischaemia.

A patient with unstable angina and known heart failure, and marked U wave alternans on the electrocardiogram is reported. Alternans of the U wave with no change in the QRS complex is extremely rare. The relevant literature is reviewed.

[Anticoagulation in cardiac pathologies (except atrial fibrillation)]. / L'anticoagulation dans les pathologies cardiaques (hors fibrillation auriculaire).

Anticoagulants, including heparins and antivitamins K are medicines which are largely prescribed in cardiology. Even though the outlines of the treatment have been clearly established for a few decades, new cardiological indications have recently appeared. The long-term treatment of cardiac valvular prosthesis by oral anticoagulants significantly reduces the risk of thrombo-embolic incident among people carrying a cardiac valvular prosthesis. In case of non-operated valvulopathy, treatment indication must be evaluated for each patient; in so doing, the connection benefit/risk must always be taken into account. In case of dilated cardiomyopathy, the treatment prescription must be limited to the patients with a high embolic risk. Other cardiological indications (apart from atrial fibrillation) must be carefully weighed up.

[Pulmonary embolism and anterior septal ischemia on the electrocardiogram: diagnostic trap. Two case reports]. / Embolies pulmonaires et ischemie antero-septale a l'electrocardiogramme: piege diagnostique. A propos de deux cas.

The authors reports two cases of pulmonary embolism which have, on ECG, an anteroseptal subepicardial ischemia which could indicate a coronary origin. The value and role of electrocardiographic findings in the diagnosis of pulmonary embolism are analysed. Once the diagnosis of pulmonary embolism has been established, the rest-ECG could allow the massive forms to be distinguished from the non-massive ones. The anteroseptal subepicardial ischemia pattern in the precordial leads is the most frequent sign of pulmonary embolism. This parameter is easy to obtain and reflects the severity of pulmonary embolism.

Myocardial stunning in hypertrophic cardiomyopathy with normal coronary arteries.

A patient with an obstructive hypertrophic cardiomyopathy and normal epicardial coronary arteries developed myocardial ischemia accompanied by a transitory apical akinesia. This wall motion dysfunction persisted for hours after the relief of myocardial ischemia.

[Hypertrophic cardiomyopathy]. / La cardiomyopathie hypertrophique.

Hypertrophic cardiomyopathy is an uncommon disease, important to recognize. Family screening is mandatory, with physical examination, EKG and echocardiography. Genetic diagnosis will modify our approach in a near future. The different treatments are described: drugs, surgery, pacing. The role of the general practitioner is complementary to the cardiologist's. His task is especially important in the first step of the diagnosis.

Effect of respiration on Doppler parameters of normal tricuspid porcine bioprosthetic valves.

The Doppler indexes of tricuspid porcine bioprosthetic valves were evaluated in twelve patients without clinical and two-dimensional echocardiographic evidence of valve dysfunction. Peak and mean pressure gradients across the prostheses were measured using the simplified Bernoulli equation. All the Doppler measurements were compared during inspiration and expiration. During inspiration peak velocity, peak gradient and mean gradient (1.52 +/- 0.28 m/s; 9.7 +/- 3.05 mmHg; 4.07 +/- 1.16 mmHg) were significantly higher than during expiration (1.28 +/- 0.8 m/s; 6.58 +/- 2.7 mmHg; 2.98 +/- 1.13 mmHg; p < 0.01) but pressure half time was not significantly different (122 +/- 62 ms versus 134 +/- 75 ms; p > 0.05). Inspiratory range of peak velocities, peak gradients, mean gradients and pressure half times were respectively 0.8-2.04 m/s; 4.9-16.6 mmHg; 1.2-7.2 mmHg; 42-340 ms while expiratory range of values was 0.8-1.93 m/s; 2.6-15 mmHg; 1.1-5.7 mmHg; 46-345 ms. These data suggest that even very long pressure half times do not indicate valve dysfunction. This study demonstrates that large variation of Doppler parameters are present during respiration and could produce inaccuracy in the assessment of bioprostheses in tricuspid position if they are not taken in consideration.

[2 cases of isolated tricuspid endocarditis following colonic intervention]. / Deux cas d'endocardite tricuspidienne isolée après intervention colique.

We report two cases of tricuspid valve endocarditis with related organisms (Enterococcus faecalis and Gemella morbillorum), some months after colonic operation. This association, without preexistent valvular pathology and without any other classical aetiology of tricuspid endocarditis, has only exceptionally been described.

[Medical treatment of coronary insufficiency in the elderly]. / Le traitement médical de l'insuffisance coronaire du sujet âgé.

Age does not modify the logical approach of the medical treatment of angina pectoris. Triggering factors have to be searched and treated. Age is not a contra-indication, but the physician has to be familiar with the drugs used in the elderly (side-effects, contra-indications, metabolism, dosages, etc.). The choice based on side-effects and contra-indications favours calcium inhibitors and nitrates. Nevertheless, beta-blocking agents give good results in the elderly, if care is taken to use them correctly. Aspirin is given at reduced dosage. Sublingual nitrates are necessary for the anginal crisis or before stress (prophylaxis). Compliance and safety are favoured by a rational therapy.

Metastatic involvement of the left atrium revealed by electrocardiographic Ta segment change.

We describe a case in whom an unusual alteration of the atrial repolarization observed on routine electrocardiogram (Ta segment depression) led to the echocardiographic diagnosis of metastatic involvement of the left atrium by a lung cancer. Electrocardiographic abnormalities in the metastatic involvement of the heart are non specific but observation of new changes may suggest the diagnosis and modify the staging and the treatment.

Doppler evaluation of left ventricular filling: effect of verapamil on non-obstructive hypertrophic cardiomyopathy.

Impaired left ventricular (LV) filling is known to be a major determinant of non-obstructive hypertrophic cardiomyopathy (HCM). Seventeen patients with non-obstructive HCM (mean age 71 years) were investigated by Doppler echocardiography, before and after oral treatment with verapamil (mean daily doses: 335 mg). Diagnosis was based on clinical and echocardiographic data. Mitral regurgitation was absent or mild. Heart rate, PQ interval and mitral regurgitation did not change after treatment. All calculated values of Doppler LV filling improved significantly: corrected relaxation time, ratio of atrial to early velocity, EF slope and pressure half-time (P less than 0.005) showed more significant differences than more sophisticated indices using time-velocity integrals of Doppler LV filling flow (P less than 0.005). Results appear to reflect an effect of verapamil on LV relaxation; a slight effect of a modified load was nevertheless not excluded. We conclude that all parameters of Doppler LV filling show marked improvement in this elderly group with non-obstructive HCM, after oral verapamil. Doppler echocardiography is an easy and useful clinical method to assess the effect of a drug on ventricular relaxation of non-obstructive HCM.

Alterations of atrial repolarization after tricyclic antidepressant drugs absorption.

We describe a case of voluntary intoxication with tricyclic antidepressant drugs: initial electrocardiogram showed alterations of atrial repolarization (Ta segment) which were more pronounced than usual ST-T alterations. Evolution was uneventful (and repolarization normalized). Tricyclic antidepressant drugs absorption can lead to Ta segment alterations, which may be a useful clue in the differential diagnosis of drugs intoxication.
