Blood product needs and transfusion timelines for the multisite massive Paris 2015 terrorist attack: A retrospective analysis.

Objective: Hemorrhage is the leading cause of death after terrorist attack, and the immediacy of labile blood product (LBP) administration has a decisive impact on patients' outcome. The main objective of this study was to evaluate the transfusion patterns of the Paris terrorist attack victims, November 13, 2015.

Methods: We performed a retrospective analysis including all casualties admitted to hospital, aiming to describe the transfusion patterns from admission to the first week after the attack.

Analysis of the medical response to November 2015 Paris terrorist attacks: resource utilization according to the cause of injury.

Purpose: The majority of terrorist acts are carried out by explosion or shooting. The objective of this study was first, to describe the management implemented to treat a large number of casualties and their flow together with the injuries observed, and second, to compare these resources according to the mechanism of trauma.

Methods: This retrospective cohort study collected medical data from all casualties of the attacks on November 13th 2015 in Paris, France, with physical injuries, who arrived alive at any hospital within the first 24 h after the events.

Slow pathway elimination for atrioventricular nodal reentrant tachycardia with the 8-mm tip cryoablation catheter: an 18-month follow-up study.

Purpose: The 9-French 8-mm tip cryoablation catheter confers a high rate of acute slow pathway (SP) elimination and an acceptable short-term outcome in patients with atrioventricular nodal reentrant tachycardia (AVNRT). The aim of this study was to investigate the long-term outcome of patients treated with this electrode in this indication.

Methods: Eighty-two patients (female = 52) with a mean age of 54.

[Atrial defibrillators or implantable atrioverters. Initial results].

The atrial defibrillator is a new non-pharmacological treatment of atrial fibrillation (AF) for restoration of sinus rhythm. This device has two programmable modes: automatic or activated by the physician or patient. In the automatic mode, the device delivers a shock synchronous with the R wave to restore sinus rhythm when AF is detected.

Preliminary clinical experience with the first dual chamber pacemaker defibrillator.

The lack of specificity of VT detection is a significant shortcoming of current ICDs. In a French multicenter study, 18 patients underwent implantation of the Defender 9001 (ELA Medical), an ICD utilizing dual chamber pacing and arrhythmia detection. Over a mean follow-up period of 7.

[Comparison of the efficacy of 2 delayed-action preparations of hydroquinidine and quinidine in the prevention of pacing induced ventricular tachycardia].

The effects of two antiarrhythmic agents, hydroquinidine and quinidine on the prevention of pacing induced sustained ventricular tachycardia (VT) were studied in 14 patients. The underlying cardiac disease was old myocardial infarction (12 patients) or dilated cardiomyopathy (2 patients). Sustained monomorphic VT was induced in 14 patients during the initial electrophysiological study performed at least 48 hours after withdrawal of all antiarrhythmic therapy.

A randomized comparison of external and internal cardioversion of chronic atrial fibrillation.

Background: Delivery of shocks within the right atrium has been reported to be more effective than conventional external shocks in converting atrial fibrillation (AF), but these two cardioversion techniques have never been compared prospectively. The purpose of this study was to compare the efficacies of external and internal cardioversion in patients with chronic AF unresponsive to prior attempts at electrical and/or pharmacological cardioversion. Low-dose amiodarone was used in all patients after cardioversion to suppress recurrences of AF.

[Oral propranolol in Wolff-Parkinson-White syndrome. Electrophysiological data].

The effects of oral propranolol were studied in 24 patients with the WPW syndrome. The average daily dose of propranolol was 130 +/- 24 mg administered in 3 doses over a period of 48 to 72 hours. Endocavitary electrophysiological study was performed 2 to 4 hours after the last dose.

[Value of systematic preventive antibiotherapy in cardiac pacemaker implantation].

The aim of this study was to assess the usefulness of prophylactic antibiotics during insertion of a cardiac pacemaker, in order to avoid infection of exteriorisation of infectious origin. The study involved two groups. One hundred and eight patients made up group I, a control group without the use of prophylactic antibiotics.

[Complex ventricular extrasystole. Value of programmed electric stimulation for evaluating the risk of sudden death].

A prospective study was carried out from May 1984 to July 1987 to determine the prognostic value of the results of programmed electrical stimulation (PES) in patients with complex ventricular ectopy. The study population comprised 118 patients, 80 with and 38 without apparent underlying cardiac disease. The PES consisted in at most 3 extrastimuli delivered to the right ventricular apex during 2 imposed basal rhythms.

Long-term follow-up of patients treated with VVI pacing and sequential pacing with special reference to VA retrograde conduction.

The aim of this prospective study is comparing long-term prognosis in patients implanted with a VVI pacemaker (group A) with those implanted with a sequential pacing device, AAI or DDD, (group B). Both groups of 45 patients each, were comparable as regards to age, sex, pacing indications, underlying heart disease, and technical conditions of implantation and were followed-up over 55 months. Atrial arrhythmias (A.
