ABSTRACT
A syndrome of transient apical ballooning without coronary stenosis, which mimics acute myocardial infarction, was recently described. Although several possible etiologic mechanisms have been proposed and investigated, the precise cause remains unclear. We describe 3 cases of transient left ventricular apical ballooning without coronary stenosis, and discuss the etiology of this syndrome, in particular the possible role of a transient intraventricular gradient.

Recientemente se ha descrito un síndrome caracterizado por discinesia (ballooning) apical transitoria, sin lesiones coronarias, que simula un infarto agudo de miocardio. Aunque se especula sobre sus posibles causas, su verdadero origen es todavía desconocido. Describimos 3 casos de este síndrome y discutimos su etiología, en particular el posible papel de un gradiente intraventricular transitorio (AU)

An arterial pseudoaneurysm is an uncommon complication of cardiovascular procedures associated with considerable morbidity and increased hospital costs. Percutaneous thrombin injection is one approach to therapy. We describe our initial experience with this technique in 3 patients, with special attention to the utility of sonographic guidance. In all cases complete closure was achieved, although one patient required additional brief extrinsic compression with the ultrasound probe.

El seudoaneurisma arterial es una complicación poco frecuente de los procedimientos cardiovasculares que conlleva una importante morbilidad e incremento en los costes de hospitalización. Una alternativa terapéutica es la administración percutánea de trombina. Describimos nuestra experiencia preliminar con esta técnica en 3 pacientes, con especial enfoque sobre la utilidad del control ecográfico. Se logró el cierre completo en los 3 casos, aunque en uno de ellos el procedimiento se completó con un breve período de compresión extrínseca con la sonda de ultrasonidos. (AU)
