[Management of non-rhythmic complications of TAVI procedures]. / Gestion des complications non rythmologiques des procédures de TAVI.

Transcatheter aortic valve (TAVI) is the treatment of choice in patients with severe symptomatic aortic stenosis at high surgical risk. Recent data have also shown favorable results in patients considered to have an intermediate operative risk, which broadens the application of this new technology. Despite its success, the TAVI procedure has been associated with life-threatening complications. Advances in preoperative screening and patient selection have reduced the incidence of these complications. When these complications occur, early recognition and rapid management are essential. The purpose of this review is to describe non-rhythmic mechanical complications attributable to TAVI procedures with their predictive factors, how to prevent and manage them.

[Optimization of systolic heart failure treatment by general practitioners after hospital discharge: Are guidelines applied?] / Optimisation du traitement de l'insuffisance cardiaque chronique par les médecins généralistes en sortie d'hospitalisation : les recommandations sont-elles appliquées ?

Heart failure is a common and serious disease, with constantly increasing incidence. General practitioners have an essential role in its management. AIM OF THE STUDY: Describe general practitioner's practice in optimizing heart failure treatment after hospital discharge. PATIENTS AND METHOD: All patients admitted for heart failure with altered ejection fraction in Nanterre's hospital cardiology department between February 2014 and January 2015 and having a general practitioner were included. Demographic, clinical, biological, ultrasound data and treatments were collected. A questionnaire was submitted to general practitioners two months after discharge. RESULTS: A total of 82 patients (age 76±12years, left ventricular ejection fraction 36±8%) were included. The target dose of angiotensin-converting-enzyme inhibitors and beta-blockers was reached for 18% of patients during hospitalization. Forty-two general practitioners answered the questionnaire, which concerned 60% of patients (n=49). None of them modified angiotensin-converting-enzyme inhibitors nor beta-blockers. The reasons were the lack of patient consultation (43%), the good tolerance (43%), the absence of habit (24%), and the attribution of this role to the cardiologist (41%). Possible improvements are: more precise hospitalization reports, alternating consultations and educational sessions. CONCLUSION: Patients with heart failure are under-treated at discharge and general practitioners do not optimize the treatment after hospital discharge. The main axis of improvement is to establish a better defined care pathway.

Tako-Tsubo syndrome after an exercise echocardiography.

The Tako-Tsubo syndrome is a clinical entity recently described that associate a chest pain occurring during a stress, an abnormal ECG and/or an increase in the troponin blood level and a transient left ventricular dysfunction with an akinesis involving generally the midsection and the apex of the heart. It has also been reported that left ventricle (LV) dysfunction may involve only the midventricle, although it seems less common. We report the case of a 66 year old woman that developed a stress-induced cardiomyopathy (Tako-Tsubo syndrome) involving the midventricle when performing an exercise echocardiography. To our knowledge, this is the first case reported in such circumstances.

[Very late intrastent thrombosis--at 27 months!]. / Une thrombose de stent très tardive...à 27 mois!

Interrupting platelet antiaggregant therapy in coronary patients treated by stenting exposes them to the risk of cardiac complications. The risk of acute thrombosis of the stent is well known but late intrastent thrombosis is less common and mainly observed with drug eluting stents. The authors report the case of a 54 year old man who had thrombosis of an ordinary stent implanted 27 months previously which occurred in the immediate post-operative period after repair of an inguinal hernia. The interruption of platelet antiaggregant therapy was relayed by flurbiprofen in accordance with recommendations of scientific societies. After a review of the literature, the authors discuss late stent thrombosis and interruption of platelet aggregant therapy in coronary patients before non-cardiac surgery.

[Marfan syndrome]. / Syndrome de Marfan.

Marfan's syndrome is a monogenetic disease with an autosomal dominant transmission generally accompanied by type I fibrillin abnormality. This widely-distributed molecule participates in the structure of connective tissues so that any aberration may result in disease of many systems: skeletal morphology, dislocation of the lens, neurological or cutaneous signs and dilatation of the aorta predisposing to dissection, mitral valve prolapse being a common association. The diagnosis, clinical because of the size of the culprit gene and the multiplicity of the possible mutations, is sometimes difficult, and diagnostic criteria have been proposed. It is important to make the diagnosis because treatment is based on the restriction of violent exercise, betablocker therapy and regular echocardiographic monitoring of the ascending aorta, the region at highest risk of dilatation and dissection. A family enquiry is essential to make the diagnosis before the onset of complications in pauci-symptomatic patients (great intra-familial variability). Pregnancy poses special problems in these patients.

[Isolated and asymptomatic Brugada syndrome. A case report]. / Syndrome de Brugada isolé et asymptomatique. A propos d'une observation.

The case report of a 32-year-old man with a Brugada syndrome is presented. He was asymptomatic and without familial history of sudden death or syncope. Diagnosis criteria for Brugada syndrome were 1--a pattern of right bundle branch block and ST-segment elevation in leads V1 and V2 on the ECG, 2--no cardiac structural anomalies. Symptomatic patients with this electrical anomaly are at high risk of sudden death and need an automatic implantable defibrillator. The outcome and the treatment of asymptomatic patients are a matter of debate and are discussed in this report.

[Incidence of acute cor pulmonale and deep venous thrombosis in acute pulmonary embolism]. / Incidence du coeur pulmonaire aigu et de la thrombose veineuse profonde dans l'embolie pulmonaire aiguë.

OBJECTIVE: Ultrasounds are a useful tool when looking for indirect evidence in favor of pulmonary embolism. The aim of this study was to determine the incidence of acute cor pulmonale and deep venous thrombosis revealed by ultrasonographic techniques in a population of patients presenting with pulmonary embolism. METHODS: 96 consecutive patients with a mean (+/- SD) age of 65 +/- 15 years, admitted to our hospital for pulmonary embolism were included in this study. The diagnosis of pulmonary embolism was made either by spiral computed tomography or selective pulmonary angiography. Each patient subsequently underwent both trans-thoracic echocardiography and venous ultrasonography. The diagnostic criterion used for defining acute cor pulmonale by echocardiography was the right to left ventricular end-diastolic area ratio over (or equal to) 0.6. Diagnosis of deep venous thrombosis was supported by the visualization of thrombi or vein incompressibility and/or the absence of venous flow or loss of flow variability by venous ultrasonography. RESULTS: Using ultrasounds, an acute cor pulmonale was found in 63% of our patients while 79% were found to have deep venous thrombosis and 92% of the patients had either acute cor pulmonale or deep venous thrombosis or both. All of the patients with proximal pulmonary embolism had acute cor pulmonale and/or deep venous thrombosis. The presence of acute cor pulmonale on echocardiography was significantly higher in patients with proximal pulmonary embolism (p < 0.0001). CONCLUSION: This study emphasizes the potential value of ultrasonographic techniques in the diagnosis of acute pulmonary embolism.
