ABSTRACT

Persistent left superior vena cava is the most common venous congenital malformation and is usually asymptomatic. Its presence could increase the difficulty for transvenous lead implantation. We report a 71-year-old woman with an idiopathic dilated cardiomyopathy, atrial fibrillation and heart failure that required biventri-cular resynchronization therapy. During the placement of the device a persistent left superior vena cava was detected. The device was placed without problems and the patient had a satisfactory postoperative evolution.

ABSTRACT

We report a 26year old patient who had a single chamber pacemaker implantation one year before. During a routine pre-operative evaluation, pacemaker dysfunction was demonstrated due to sensing and pacing failure, associated to left pectoral muscle rhythmic contraction. Chest X-ray confirmed Twiddler syndrome, in which twisting or rotation of the device inside the pocket results in lead dislodgement and device malfunction.

ABSTRACT

Los galactoceles se hacen semisólidos a medida que evolucionan; por lo tanto; la clínica, la imagenología y la citopatología sufren algunos cambios. Por estas razones los hemos clasificados en tres estadios. Estadio I, o agudo, de contenido líquido y aspecto uniforme. Estadio II, o intermedio, con contenido líquido y semisólido, de aspecto mixto. Estadio III, o crónico, de contenido semisólido y aspecto grumoso. La ecotomografía mamaria revela imagen anecogénica en el estadio I, mixta en el II e hipoecogénica en el III. La mamografía en los estadios I y II ocacionan dudas diagnósticas por lo que requieren complemento ecotomográfico, no así en el estadio III, donde las imagenes son propias: presencia de cápsula, fondo grumoso como copos de nieve y a veces calcificaciones gruesas. La citopatología también muestra variaciones en los diferentes estadios. Los galactoceles estudiados tenían como antecedentes embarazo y lactancia
