Subsequent full publication of abstracts presented in the annual meetings of the Spanish Society of Cardiology.
2013
Abstract Introduction and objectives The Spanish Society of Cardiology holds an annual national meeting with a large number of presentations but the number of full-text publications resulting from these presentations and the journals accepting these manuscripts is unknown. This study aimed to identify the full-text publication rate of accepted abstracts and to analyze the bibliometric features of subsequent publications. Methods We randomly selected a sample of 300 oral presentations at the meetings of the Spanish Society of Cardiology in 2002, 2005 and 2008. Subsequent publications were identified through the Science Citation Index-Expanded, Scopus, Indice Medico Espanol , and Indice Bibli…
Contemporary spinal cord protection during thoracic and thoracoabdominal aortic surgery and endovascular aortic repair: a position paper of the vascu…
2015
Ischaemic spinal cord injury (SCI) remains the Achilles heel of open and endovascular descending thoracic and thoracoabdominal repair. Neurological outcomes have improved coincidentially with the introduction of neuroprotective measures. However, SCI (paraplegia and paraparesis) remains the most devastating complication. The aim of this position paper is to provide physicians with broad information regarding spinal cord blood supply, to share strategies for shortening intraprocedural spinal cord ischaemia and to increase spinal cord tolerance to transitory ischaemia through detection of ischaemia and augmentation of spinal cord blood perfusion. This study is meant to support physicians cari…
Branch ligatures and blood aspiration for post-traumatic superficial temporal artery pseudoaneurysm: surgical technique
2014
The aim of this study is to report a new minimally invasive technique of superficial temporal artery (STA) pseudoaneurysm treatment. Several surgical options have been employed to treat STA pseudoaneurysms. To address this rare condition, the employed techniques are ligation and excision of the aneurysm, endovascular coil embolization or percutaneous ultrasound-guided thrombin injection. Between techniques no significant differences are reported in terms of outcomes. The decision to adopt a technique depends on STA pseudoaneurysm morphology and surgeon preference. In the present report, STA pseudoaneurysm afferent and efferent branches were identified by ultrasound in a 92-year-old female. …
Frequency of Left Ventricular Hypertrophy in Non-Valvular Atrial Fibrillation
2015
Left ventricular hypertrophy (LVH) is significantly related to adverse clinical outcomes in patients at high risk of cardiovascular events. In patients with atrial fibrillation (AF), data on LVH, that is, prevalence and determinants, are inconsistent mainly because of different definitions and heterogeneity of study populations. We determined echocardiographic-based LVH prevalence and clinical factors independently associated with its development in a prospective cohort of patients with non-valvular (NV) AF. From the "Atrial Fibrillation Registry for Ankle-brachial Index Prevalence Assessment: Collaborative Italian Study" (ARAPACIS) population, 1,184 patients with NVAF (mean age 72 ± 11 yea…
Endoluminal Stent-Graft Relining of Visceral Artery Bypass Grafts to Treat Perigraft Seroma
2013
PURPOSE: To describe the endovascular treatment of intra-abdominal perigraft seromas associated with small-caliber expanded polytetrafluoroethylene (ePTFE) grafts. CASE REPORTS: Two patients who underwent hybrid repair of thoracoabdominal aortic aneurysms in which renovisceral bypass grafts were implanted presented with large, symptomatic perigraft seromas. The 5- to 8-mm-diameter ePTFE bypass grafts believed to be involved in the seromas were successfully relined with self-expanding Viabahn stent-grafts in percutaneous procedures. The patients' symptoms were relieved, and imaging follow-up (18 and 10 months, respectively) has shown near complete resorption of the seromas. CONCLUSION: It is…
Quantifying the complexity of short-term heart period variability through K nearest neighbor local linear prediction
2008
The complexity of short-term heart period (HP) variability was quantified exploiting the paradigm that associates the degree of unpredictability of a time series to its dynamical complexity. Complexity was assessed through k-nearest neighbor local linear prediction. A proper selection of the parameter k allowed us to perform either linear or nonlinear prediction, and the comparison of the two approaches to infer the presence of nonlinear dynamics. The method was validated on simulations reproducing linear and nonlinear time series with varying levels of predictability. It was then applied to HP variability series measured from healthy subjects during head-up tilt test, showing that short-te…
Exploring causal interactions between blood pressure and RR interval at the respiratory frequency
2006
The mechanisms underlying the relationship between RR interval and systolic arterial pressure (SAP) variability at the respiratory frequency are still object of discussion. In this study, the information on directionality provided by causal cross-spectral analysis was exploited to infer possible influences of respiration on cardiovascular parameters variability. The ability of causal analysis to account for directionality in RR-SAP interrelationships in presence of respiratory exogenous effects was first tested on model simulations. Hence, real data measured on healthy subjects during spontaneous and paced breathing at 0.25 Hz were analysed. The results obtained in real data were consistent…

Predilation, sizing and post-dilation scoring in patients undergoing everolimus-eluting bioresorbable scaffold implantation for prediction of cardiac…
2017
Aims: The aim of the study was to develop a scoring model to evaluate the quality of bioresorbable vascular scaffold (BVS) implantation and determine the model's usefulness in predicting adverse cardiac events. Methods and results: The implantation technique and clinical outcomes of 1,736 lesions treated with BVS were analysed using the GHOST-EU registry. Predilation, scaffold sizing, and post-dilation (PSP) were scored according to the hazard model derived from the weight of these variables. The primary end-point was a one-year device-oriented composite endpoint (DoCE) composed of cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularisation. Def…
Clinical outcomes of patients with diabetes mellitus treated with Absorb bioresorbable vascular scaffolds: a subanalysis of the European Multicentre …
2017
Background Data on the clinical performance of bioresorbable scaffolds in patients with diabetes mellitus (DM) are still limited. The present study reported 1-year clinical outcomes associated with the use of everolimus-eluting bioresorbable vascular scaffolds (Absorb BVS; Abbott Vascular, Santa Clara, CA) in DM patients. Methods and Results This was a subanalysis from the GHOST-EU (Gauging coronary Healing with biOresorbable Scaffolding plaTforms in Europe) multicenter retrospective registry including patients treated with Absorb BVS between November 2011 and September 2014. In this study, a comparative analysis stratified according to DM was performed. The primary endpoint was target lesi…
