Pericardial thrombus and cardiac tamponade after pericardiocentesis with intact heart walls.

A young patient affected by a lung neoplasm, presented at emergency department with cardiac tamponade, underwent pericardiocentesis with a prompt restoration of hemodynamic stability. An hour later, the patient presented again signs of tamponade, without evidence of fluids in the drainage that was left in pericardial space. The echocardiography revealed an intrapericardial thrombus compressing the right chambers.

Sustained prognostic value of dobutamine stress echocardiography for late cardiac events after major noncardiac vascular surgery.

Background: Late cardiac events after major noncardiac vascular surgery are an important cause of morbidity and mortality. We studied the prognostic value of preoperative dobutamine stress echocardiography, relative to clinical risk assessment, in predicting late cardiac events.

Methods And Results: Three hundred sixteen patients undergoing major vascular surgery were studied.

Diastolic abnormalities in systemic sclerosis: evidence for associated defective cardiac functional reserve.

Objective: To investigate the pattern of diastolic abnormalities in patients with systemic sclerosis (SSc) and the relationship between impaired ventricular filling and systolic function.

Methods: Twenty four patients with SSc underwent M-mode and two dimensional echocardiography using echo-Doppler and gated blood pool cardiac angiography, both at rest and after exercise.

Results: An impaired diastolic relaxation of the left ventricle was detected in 10 of the 24 patients with SSc.

T wave normalization during dobutamine stress testing in patients with non-Q wave myocardial infarction. A marker of myocardial ischaemia?

Unlabelled: Conflicting results in a heterogenous patient population have been described on the functional significance of stress-induced T wave normalization in the ECG. The aim of this study was to evaluate the relationship between T wave normalization during dobutamine stress testing and stress-induced ischaemia evaluated by echocardiography and myocardial perfusion scintigraphy in patients with previous non-Q wave myocardial infarction. Among 520 patients who underwent dobutamine stress, testing in conjunction with simultaneous echocardiography and 201 thallium or sestamibi SPECT for evaluation of suspected myocardial ischaemia, 36 were selected according to the following criteria: previous non-Q wave myocardial infarction, normal QRS, negative T waves in two or more ECG leads and no significant ST segment depression or elevation at rest or during stress.

Analysis of interinstitutional observer agreement in interpretation of dobutamine stress echocardiograms.

Objectives: This study sought to determine the degree of interinstitutional agreement in the interpretation of dobutamine stress echocardiograms.

Background: Dobutamine stress echocardiography involves subjective interpretation. Consistent methods for acquisition and interpretation are of critical importance for obtaining high interobserver agreement and for facilitating communication of test results.
