BACKGROUND Ultrasound (US) guidance increases safety and efficacy in vascular cannulation and is considered the standard of care. However, barriers including workflow interference and the need to be assisted by a second operator limit its adoption in clinical routine. The use of wireless US (WUS) may overcome these barriers. The aim of this study was to(More)
AIMS Catheter-tissue contact is critical for effective lesion creation. The objective of this study was to determine in an experimental swine model the pathological effects of cavo-tricuspid isthmus ablation using two systems that provide reliable measures of the pressure at the catheter tip during radiofrequency ablation procedures. METHODS AND RESULTS(More)
BACKGROUND Flow entering the left ventricle is reversed toward the outflow tract through rotating reversal flow around the mitral valve. This was thought to facilitate early ejection, but had not been proved to date. We hypothesized that perfect coupling between reversal and ejection flow would occur at optimal atrioventricular delay (AVD), contributing to(More)
Continuous medical training (CMT) has proved to be an effective method to improve and sustain professional medical competence.1,2 Consequently, several studies have assessed the effectiveness and the impact of different strategies and educational methodologies applied to CMT. However, the available evidence in this context is relatively scarce, limiting the(More)
BACKGROUND The annual volume of implants may condition and determine many aspects of cardiac resynchronization therapy (CRT). METHODS After the Spanish centers performing CRT were identified, data were recorded voluntarily by each implantation team from September 2010 to September 2011. RESULT A total of 88 implanter centers were identified, and of(More)
Atrial fibrillation is the most frequent supraventricular arrhythmia. The goals for the treatment of this arrhythmia are symptom control and reducing cardiovascular morbidity and mortality. In elderly patients with no symptoms we must indicate therapy based on rate control. On the other side, in young patients without heart disease, those very symptomatic(More)
INTRODUCTION AND OBJECTIVES A cross-sectional study of cardiac resynchronization therapy use in Spain was performed to analyze problems with indications, implantation, and patient follow-up. METHODS Spanish cardiac resynchronization therapy implanter centers were identified, then the department members were surveyed and the data were recorded by each(More)
