Infectious complications associated with short-term mechanical circulatory support in urgent heart transplant candidates

2021

[Abstract] Introduction and objectives. Short-term mechanical circulatory support is frequently used as a bridge to heart transplant in Spain. The epidemiology and prognostic impact of infectious complications in these patients are unknown. Methods. Systematic description of the epidemiology of infectious complications and analysis of their prognostic impact in a multicenter, retrospective registry of patients treated with short-term mechanical devices as a bridge to urgent heart transplant from 2010 to 2015 in 16 Spanish hospitals. Results. We studied 249 patients, of which 87 (34.9%) had a total of 102 infections. The most frequent site was the respiratory tract (n = 47; 46.1%). Microbiol…

Preoperatory Anxiety in Patients Undergoing Cardiac Surgery.

2019

Anxiety is a feeling of discomfort produced in face of an unknown event, as an impending cardiac surgery, that can lead to inconveniences in the intervention and subsequent recovery. Being the purpose of this research to analyze pre-surgical anxiety, a descriptive cross-sectional study among patients undergoing cardiac surgery was carried out. Data about sociodemographic variables were collected and the level of anxiety prior to surgery was assessed using the STAI-S scale. Subsequently, descriptive data analyses were performed, relationships among variables were analyzed, and a binary logistic regression model was developed in order to analyze the role of the variables involved in the devel…

Impact of Residual Mitral Regurgitation on Survival After Transcatheter Edge-to-Edge Repair for Secondary Mitral Regurgitation.

2021

OBJECTIVES The aim of this study was to assess the impact of residual mitral regurgitation (resMR) on mortality with respect to left ventricular dilatation (LV-Dil) or right ventricular dysfunction (RV-Dys) in patients with secondary mitral regurgitation (SMR) who underwent mitral valve transcatheter edge-to-edge repair (TEER). BACKGROUND The presence of LV-Dil and RV-Dys correlates with advanced stages of heart failure in SMR patients, which may impact the outcome after TEER. METHODS SMR patients in a European multicenter registry were evaluated. Investigated outcomes were 2-year all-cause mortality and improvement in New York Heart Association functional class with respect to MR reduction…

Recurrence quantification analysis as a tool for complex fractionated atrial electrogram discrimination

2012

International audience; Atrial fibrillation is the most encountered pathology of the heart rate. The reasons of its occurrence and its particular characteristics remain unknown, resulting from complex phenomena interaction. From these interactions emerges Complex Fractionated Atrial Electrograms (CFAE) which are useful for the ablation procedure. This study presents a method based on nonlinear data analysis, the Recurrence Quantification Analysis (RQA) applied on intracardiac atrial electrograms to detect CFAE particularities. The results obtained on areas previously tagged by a cardilogist show a good sensitivity to CFAE. Combination of RQA features offers a larger discrimination potential…

Towards real-time detection of cognitive effort in driving: Contribution of cardiac measurement

2016

En 2013, on estime que 40 à 50% des accidents corporels seraient dus à des défauts d'attention de la part du conducteur. Des études récentes ont mis en évidence la possibilité de détecter des états attentionnels dégradés afin de pouvoir mieux assister le conducteur ; ce thème de recherche représente donc un nouveau gisement de sécurité routière. Cette étude se concentre sur la détection de l'effort cognitif fournit par les conducteurs et cherche, par l'étude de la variation du rythme cardiaque, à identifier un indicateur d'effort sensible sur de courtes fenêtres temporelles.Chacun des 18 participants a passé 8 conditions expérimentales sur simulateur de conduite : la moitié où seule une tâc…

Past and present work practices of European interventional cardiologists in the context of radiation protection of the eye lens—results of the EURALO…

2018

International audience; This paper investigates over five decades of work practices in interventional cardiology, with an emphasis on radiation protection. The analysis is based on data from more than 400 cardiologists from various European countries recruited for a EURALOC study and collected in the period from 2014 to 2016. Information on the types of procedures performed and their annual mean number, fluoroscopy time, access site choice, x-ray units and radiation protection means used was collected using an occupational questionnaire. Based on the specific European data, changes in each parameter have been analysed over decades, while country-specific data analysis has allowed us to dete…

Medical evaluation of athletes: Exercise testing

2020

Exercise testing in athletes is used to (a) evaluate baseline fitness and prescribe an exercise program or training zones, (b) evaluate continued progress after engaging in exercise training over a period of time, (c) diagnose cardiopulmonary conditions affecting exercise performance, and, (d) provoke arrhythmias or evaluate hemodynamic response to exercise in an athlete with a known cardiovascular condition to determine whether it is safe to participate in competitive sports. Exercise testing is not part of routine pre-participation (PPS) screening; however, it can supplement the clinical work-up of athletes with pathological findings during PPS and/or with symptoms. In several conditions …

Evaluation of postoperative myocardial injury by heart-type fatty acid-binding protein in off-pump coronary artery bypass grafting surgery

2015

Abstract Background and goal of study Postoperative myocardial infarction is a serious and frequent complication of cardiac surgery. Nonetheless, diagnosis in this context is occasionally challenging. We sought to evaluate the kinetics and diagnostic accuracy of the new biomarker “heart-type fatty acid-binding protein” (h-FABP) in the early detection of myocardial injury in patients undergoing off-pump coronary artery bypass grafting, compared with classical biomarkers. Materials and methods A prospective study was conducted on 17 consecutive patients who underwent off-pump coronary artery bypass grafting during a 2-month period. Blood samples were drawn for measurement of myocardial ischem…

Aortic Annulus Stabilization Using Internal Rings

2017

The past 20 years have seen the growing range of valve lesion etiologies turn nonvalvular conditions into the primary causes of aortic regurgitation [1]. Valves present relatively small lesions of the leaflets and concomitant dilatation of the ascending aorta with aortic regurgitation that can be explained thanks to our improved knowledge of the functional aortic annulus’ role in valve function. The geometric relations and dynamic behavior of aortic root components have been seen to ensure valve competence when leaflets have no structural lesions [2].
