Predictors of Conversion from Radial Into Femoral Access in Cardiac Catheterization

Background: Fewer bleeding complications and early ambulation make radial access a privileged route for cardiac catheterization. However, transradial (TR) approach is not always successful, requiring its conversion into femoral access. Objectives: To evaluate the rate of conversion from radial into femoral access in cardiac catheterization and to identify its predictors. Methods: Prospective dual-center registry, including 7632 consecutive patients undergoing catheterization via the radial access between Jan/2009 and Oct/2012. We evaluated the incidence of conversion into femoral access and its predictors by logistic regression analysis. Results: The patients’ mean age was 66 ± 11 years, and 32% were women. A total of 2969 procedures (38.4%) were percutaneous coronary interventions (PCI), and the most used first intention arterial access was the right radial artery (97.6%). Radial access failure rate was 5.8%. Independent predictors of conversion from radial into femoral access were the use of short introducer sheaths (OR 3.047, CI: 2.380-3.902; p < 0.001), PCI (OR 1.729, CI: 1.375-2.173; p < 0.001), female sex (OR 1.569, CI: 1.234-1.996; p < 0.001), multivessel disease (OR 1.457, CI: 1.167-1.819; p = 0.001), body surface area (BSA) ≤ 1.938 (OR 1.448, CI: 1.120-1.871; p = 0.005) and age > 66 years (OR 1.354, CI: 1.088-1.684; p = 0.007). Conclusion: Transradial approach for cardiac catheterization has a high success rate and the need for its conversion into femoral access in this cohort was low. Female sex, older age, smaller BSA, the use of short introducer sheaths, multivessel disease and PCI were independent predictors of conversion into femoral access.

Análisis jurisprudencial del derecho al secreto de las comunicaciones (art. 18.3 C.E.)

Este trabajo aspira a plantear en qué estado se halla actualmente la regulación de la intervención de las comunicaciones telefónicas en nuestro ordenamiento jurídico. Nuestro enfoque en el presente trabajo será plantearnos la legitimidad o licitud de las medidas de intervención telefónica así como su ámbito de validez y eficacia a efectos de su utilización en el proceso penal en el sentido de qué límites o controles deben establecerse. Asimismo analizaremos el derecho fundamental al secreto de las comunicaciones consagrado en el art. 18.3 de la Constitución y la regulación positiva de dicho derecho en nuestro ordenamiento jurídico. En definitiva, se trata de plantear la problemática en términos amplios para posteriormente profundizar y abordar cuestiones de gran relevancia tales como qué sucede o qué tratamiento debe darse a los llamados hallazgos casuales o a la prueba ilegalmente obtenida, elementos que debido a su extensión trataremos de una forma puntual y que serán objeto de desarrollo en un trabajo posterior.
