Diagnostic Transaortic Cardioscopy of the Left Ventricle

Preoperative diagnosis of pathologic intracardiac structures by noninvasive techniques is sometimes difficult or even impossible. In these cases a heart operation is required with opening of one or more cardiac chambers. We demonstrate direct visualization of the left ventricular cavity by transaortic cardioscopy in a patient with a pathologic intraventricular structure. With this technique we could avoid ventriculotomy.
