[Endocarditis of pacemaker or implantable cardioverter-defibrillator leads].

Background: Infective endocarditis includes the endovascular devices infection. The main objective was to evaluate the clinical characteristics and evolution of the endocarditis related to electronics devices.

Case Reports: Between 2002 - 2007 periods were identified 7 patients, age average of 56.

Cardiac lipoma: a rare cause of right-to-left interatrial shunt with normal pulmonary artery pressure.

Cardiac lipomas are rare tumors. They usually remain asymptomatic for a long time and cause angina, arrhythmia, dysfunction of the ventricles or valves, and peripheral embolization during the later stages of development. There is little or no information about right-to-left interatrial shunt with normal pulmonary artery pressure, produced as a consequence of the infiltration of the atrial septum, the right atrial wall, and the myocardium because of the presence of fat in patients with platypnea-orthodeoxia syndrome.

Mid-Term Results of Dual-Chamber Pacing in Children with Hypertrophic Obstructive Cardiomyopathy.

BACKGROUND: Permanent dual-chambered pacing (DDD) is an alternative to surgical treatment in patients with severe hypertrophic obstructive cardiomyopathy (HOCM) who do not have a satisfactory response to medical treatment. METHODS: Five children with severe HOCM still symptomatic despite medical treatment underwent permanent DDD pacing and were followed for 21 +/- 9.7 months.

Right Ventricular Outflow Tract Tumor Mimicking a Thrombus in the Main Pulmonary Artery.

Primary sarcomas of the pulmonary artery and right ventricle are rare, and their presentation is unusual in clinical practice; therefore, their diagnosis is often missed or delayed. The progression of the obstruction from the outflow tract of the right ventricle to the pulmonary artery resembles massive pulmonary embolism. We present a case of one of these tumors which mimicked transesophageal echocardiography (TEE), a massive pulmonary embolism.
