[Percutaneous extraction of intravascular foreign bodies: a series of 38 cases].

Background And Objectives: Retained foreign bodies or embolization in cardiac chambers is a relatively common clinical problem. As experience was acquired, it became apparent that failure to remove such fragments could result in morbility or mortality. In the past, surgical removal was the only method available.

[Use of transdermal scopolamine in the prevention of neuro-cardiogenic syncope induced by the tilt test].

Introduction And Objectives: The underlying mechanism of syncope induced by head-up tilt test is still incompletely understood. It has been proposed a sudden increase in parasympathetic's activity induced by the excessive activation of the cardiac mechanoreceptors. The aim of our study was to evaluate the clinical, electrocardiographic and hemodynamic responses to head-up tilt test before and after treatment with transdermal Scopolamine (anticholinergic agent).

[Usefulness of early exercise test after anterior infarction in the diagnosis of multivessel disease].

Objective: The aim of the present study was to determine the reliability of early exercise test to detect multivessel disease in survivors of an uncomplicated first anterior Q-wave myocardial infarction.

Methods: Among 100 consecutive patients 64 (aged 55 +/- 10 years) were included in the study. Thirty-four patients (53.

[Echocardiography during transesophageal atrial pacing. Its applicability and diagnostic value].

Introduction And Objectives: Atrial pacing has been proposed as an alternative method to the isotonic exercise, to induce ischemia, and, joined to two-dimensional echocardiography, as one of the main modalities in stress echo. In order to analyse its applicability and diagnostic value in assessing coronary artery disease this study was undertaken.

Patients And Methods: 52 patients referred to coronarography for suspicion or evaluation of ischemic disease, were submitted to this technique.
