Intravascular ultrasound imaging of human cerebral arteries.

The aim of this study was to assess the feasibility of imaging cerebral arteries in vitro with intravascular ultrasound and to establish a correlation between echographic images and corresponding histological architecture. Intravascular ultrasound imaging was performed using a 30-MHz, 4.3F ultrasound probe.

Electrocardiographic markers of abnormal left ventricular wall motion in acute subarachnoid hemorrhage.

A reversible and presumably neurogenic form of myocardial dysfunction may occur following subarachnoid hemorrhage (SAH), but the relationship of this finding to electrocardiographic abnormalities remains unclear. To clarify this issue, serial electrocardiograms (ECGs, mean 6.2 per patient) and echocardiograms (mean 3.

Cardiac injury associated with neurogenic pulmonary edema following subarachnoid hemorrhage.

Objective: To describe the clinical features of cardiac injury associated with neurogenic pulmonary edema (NPE) in patients with acute subarachnoid hemorrhage (SAH).

Background: NPE is generally viewed as a form of noncardiogenic pulmonary edema related to massive sympathetic discharge.

Methods: Case series.

Detection of multiple papillary fibroelastomas of the tricuspid valve by transesophageal echocardiography.

A 66-year-old man without symptoms, referred for the treatment of moderate hypertension, was found to have a right atrial mass by two-dimensional echocardiography. On transesophageal echocardiography two masses were detected on the tricuspid valve, the first one on the posterior leaflet and the second smaller one on the anterior leaflet. These findings were confirmed at surgery.

Use of transesophageal echocardiography in the detection and consequences of an intracardiac bullet.

A 17-year-old male sustained a gunshot injury to the chest. Transesophageal echocardiography showed the presence of a retained bullet in the pericardium and the absence of an intracardiac shunt, which provided important information for the treatment of the patient.

Tissue plasminogen activator: hospital experience.

Tissue plasminogen activator (t-PA) is administered safely and efficiently in the treatment of acute myocardial infarction (MI). A study of 74 patients administered t-PA for acute MI associated with a low complication rate showed an acceptable patency rate, and a good outcome.
