Diagnosis of cardiac lesions by contrast echocardiography.
Contrast M-mode echocardiography was utilized to study animals with congenital and acquired cardiac defects. Contrast was produced through the rapid injection of isotonic NaCl solution, the patient's blood, or indocyanine green dye into the circulation. Peripheral vein and intracardiac injections of contrast material were used to document ventricular septal defect, tetralogy of Fallot, atrial septal defect, and mitral valve regurgitation. The technique was safe and useful for both small and large animals.
