Mediastinal Tumour Simulating Left Ventricular Enlargement. Diagnosis by Means of Angiocardiography

Left Ventricular Angiocardiography by Transseptal Puncture of the Left Atrium.

SELECTIVE angiocardiography of the left side of the heart is of prime importance for the accurate preoperative diagnosis of those lesions involving the mitral valve, ventricular septum, outflow tract of the left ventricle, or the aorta itself. The injection of contrast medium into the pulmonary artery for the demonstration of the left atrium and left ventricle is less satisfactory than the dire...

Echocardiographic diagnosis of mobile left ventricular tumour.

Echocardiography detected a mobile left ventricular tumour. The tracing showed a cluster of echoes in the left ventricular outflow tract corresponding to the location of the tumour as confirmed by cineangiograms. At operation, a thrombus was discovered, attached to a chorda tendineae.

Nontraumatic determination of left ventricular ejection fraction by radionuclide angiocardiography.

Previous reports have suggested that left ventricular ejection fraction can be assessed by recording the passage of peripherally administered radioactive bolus through the heart. The accuracy and validity of this technique were examined in 20 patients undergoing diagnostic cardiac catheterization. 99m-Tc-human serum albumin was injected via a central venous catheter into the superior vena cava ...

Diagnosis of cor triatriatum by left ventricular angiocardiography. Report of a case.

Left ventricular angiocardiography in atrioventricular defects.

The variation in the pathological anatomy of atrioventricular defects influences presentation, prognosis, and the results of surgical treatment. In particular the structure and function of the mitral valve have an important bearing on the success of surgical correction of the deformed valve. The purpose of this paper is to indicate the value of left ventricular angiocardiography in assessing th...
