[Hemarthrosis as a hemorrhagic complication after thrombolytic treatment].

Hemorrhage of variable severity is the main complication of thrombolytic treatment. We present the case of a rare hemorrhagic location after the use of this treatment for acute myocardial infarction, as ankle hemarthrosis. In the first twelve hours the patient had a joint hemorrhagic effusion with refractory pain and arthrocentesis was required.

[Accuracy and clinical applicability of the echocardiographic automated endocardial boundary detection system: correlation and bias analysis].

Introduction And Objectives: Automated edge detection of endocardial borders is a new echo system that permits on-line delineation and tracking of blood-tissue interface and offers promise for measuring cyclic changes in cavity area and the assessment of left ventricular function on-line. Its accuracy has only been analyzed by linear regression and its applicability in unselected patients is not clearly established.

Methods: We analyzed the accuracy and clinical applicability of the system in 150 patients.

[The usefulness of transesophageal echocardiography in general intensive care units].

Background And Objectives: It's well known the utility of transesophageal echocardiography in the evaluation of cardiological patients that are critically ill. However, there is less experience about this usefulness in non-cardiological critically ill patients.

Methods: To assess the utility and safety of the method we analyzed 51 correlative studies of patients admitted to our general Intensive Care Unit.

[The accuracy and applicability of different methods in the Doppler technic for the quantification of mitral stenosis].

Introduction And Objectives: We analyse the applicability and accuracy of the various Doppler methods for quantification of mitral stenosis as well as the value of combining measurements.

Patients And Methods: The study comprised 74 patients with reliable planimetry of mitral orifice. The following Doppler methods were tested: a) pressure half-time; b) color jet width at the mitral valve orifice in the apical long-axis view (short diameter) and its width in the 90 degree rotated view (long diameter), assuming an elliptic mitral orifice; c) proximal isovelocity surface area from the 4-chamber view assuming a hemispheric surface, and d) the continuity equation.
