Short- and midterm follow-up results of valvuloplasty with balloon catheter for congenital aortic stenosis

OBJECTIVE: To report short and midtem follow-up results of balloon aortic valvuloplasty to treat congenital aortic stenosis. METHODS: Seventy-five patients (median age: 8 years) underwent the procedure through the retrograde femoral or carotid route. RESULTS: The procedure was completed in 74 patients (98.6%). The peak-to-peak systolic gradient dropped from 79.6±27.7 to 22.3±17.8 mmHg (P<0.001), the left ventricular systolic pressure dropped from 164±39.1 to 110±24.8 mmHg (P<0.001), and the left ventricular end diastolic pressure dropped from 13.3±5.5 to 8.5±8.3 mmHg (P< 0.01). Four patients (5.3%) died due to the procedure. Aortic regurgitation (AoR) appeared or worsened in 27/71 (38%) patients, and no immediate surgical intervention was required. A mean follow-up of 50±38 months was obtained in 37 patients. Restenosis and significant AoR were observed in 16.6% of the patients. The estimates for being restenosis-free and for having significant AoR in 90 months were 60% and 50%, respectively. CONCLUSION: Aortic valvuloplasty was considered the initial palliative method of choice in managing congenital aortic stenosis, with satisfactory short- and midterm results.

Fibrinolytic therapy for thrombosis in cardiac valvular prosthesis short and long term results

OBJECTIVE: To assess the short- and long-term results of the use of streptokinase (SK) for the treatment of thromboses in cardiac valvular prostheses. METHODS: Seventeen patients with cardiac prosthetic thrombosis diagnosed by clinical, echocardiographic, and radioscopic findings underwent fibrinolytic treatment with a streptokinase bolus of 250,000 U followed by 100.000 U/hour. Short- and long-term results were assessed by radioscopy and echocardiography. RESULTS: Of the 17 patients, 12 had mechanical double-disk prostheses (4 aortic, 6 mitral, 2 tricuspid), 4 had single-disk prostheses (2 aortic, 1 mitral, and 1 tricuspid), and 1 had a tricuspid bioprosthesis. The success rate was 64.8%, the partial success rate was 17.6%, and the nonsuccess rate was 17.6%. All patients with a double-disk prosthesis responded, completely or partially, to the treatment. None of the patients with a single-disk prosthesis had complete resolution of the thrombosis. The time of streptokinase infusion ranged from 6 to 80 hours (mean of 56 h). The mortality rate due to the use of streptokinase was 5.8% and was secondary to cerebral bleeding. During streptokinase infusion, 3 (17.6%) embolic episodes occurred as follows: 1 cerebral, 1 peripheral, and 1 coronary. The rethrombosis index was 33% in a mean follow-up of 42 months. CONCLUSION: The use of fibrinolytic agents was effective and relatively safe in patients with primary thrombosis of a double-disk prosthesis. A fatal hemorrhagic complication occurred in 1 (5.8%) patient, and embolic complications occurred in 3 (17.6%) patients. In a mean 42-month follow-up, 67% of the patients were free from rethrombosis.

¿Ideología es compatible con marketing? Estudio comparativo de la comunicación en las campañas presidenciales en América Latina

Existe un discurso muy aceptado en la vida política, en los medios y en parte del sector profesional, que determina que las campañas electorales deben estar exentas de contenidos ideológicos explícitos para ser eficaces. A pesar de la extendida consideración bibliográfica, pero mucho más mediática, respecto a que en la década de los noventa el voto ha perdido gran parte de su sustancia ideológica y se ha orientado a la búsqueda de mensajes e imágenes, las campañas en América Latina (y del mundo en general) han demostrado, entrado el siglo veintiuno, que ello debe relativizarse en parte. En la práctica regional, los eslóganes no dan cuenta plenamente de todo el contenido dentro de las propias campañas, especialmente de las posiciones ideológicas y del uso de la negatividad en el contenido interno de cada mensaje desarrollado. Pero ello no es causal alguna para sostener que las campañas estén despegadas plenamente de planteos ideológicos que, incluso, suelen presentarse de manera explícita, sea por los propios candidatos, sea por la ubicación ideológica que los medios hacen de las propuestas y los partidos, sea también por la propia ubicación que los partidos hacen de sus partidos opositores en términos de franca diferenciación. La investigación intenta ampliar qué se entiende actualmente por ideología para dar paso a una conceptualización del concepto que permita profesionalizar su uso y sistematizar las prácticas discursivas electorales en perspectiva comparada. En esta línea, problematizar la concepción de ideología, es también problematizar qué se entiende por comunicación ideológica y resolver un proceso metodológico que permita confirmar o no el predominio de mensajes ideológicos en las campañas electorales presidenciales en América Latina. En el caso de que las campañas muestren un claro sentido ideológico en su contenido es muy importante identificar cómo se comunica esa ideología en las campañas y esbozar una sistematización respecto a la forma en que ese discurso se presenta para el electorado, tratando de describir el proceso desde el análisis de contenido especialmente. El intento es confirmar si en las últimas campañas presidenciales en América Latina se identifican discursos con claros rasgos ideológicos, si la ideologización viene acompañada de un encuadre de espectacularización y si la personalización no es un impedimento para que se transmitan mensajes ideologizados..
