Left Ventricular Angiocardiography by Transseptal Puncture of the Left Atrium

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...

Left heart catheterization by direct ventricular puncture.

Attempts at complete catheterization of the left heart by transseptal and retrograde routes are not always completely informative nor entirely free from complications (Crowley and Parkin, 1956; KavanaghGray and Drake, 1958; Aldridge, 1964; Samet, Bernstein, and Levine, 1965; Christiansen and Wennevold, 1966), and further alternative means of obtaining haemodynamic information from the left side...

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...

Effect of Transseptal Left Atrial Puncture upon Cardiac Output.

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 ...
