Bidimensional contrast echocardiological examinations were carried out in 120 patients with dynamically focused multiscan. Ultrasonic contrast was produced by a push injection of 10 ml of isotonic saline or of 5% glucose in H2O injected into an antecubital vein through an 18 gauge needle. Contrast studies were observed on a television monitor and recorded on videotape for detailed off-line analysis. All the echocardiological diagnoses were confirmed during catheterization. A few typical clinical examples are illustrated, including a patient with Ebstein''s anomaly, a case of tricuspid regurgitation, atrial and ventricular septal defects and a left ventricular ultrasound angiocardiogram. Bidimensional contrast echocardiology opens a new field for the assessment of remediable cardiac lesions.
