Angiographic Estimation of Right Ventricular Volume in Man

Angiographic estimation of right ventricular volume in man.

Influence of Right Ventricular Hemodynamics on Left Ventricular Diastolic Pressure-Volume Relations in Man

To clarify the mechanism of displacement of the left ventricular diastolic pressure-volume function with alteration of loading conditions, the effects of nitroglycerin on pressure-volume relations in 13 patients were compared with those of amyl nitrite in 13 other patients during cardiac catheterization. After nitroglycerin, average systemic mean arterial pressure declined by 15.1 mm Hg (17%) a...

Measurement of Ventricular Volume in Man

SINCE THE INITIAL observations of William Harvey and the physiologic studies of Ernest Starling, the importance of changes in volume in the ventricles of the heart has been recognized. In physiologic and clinical studies of the heart, measurements of chamber pressure and cardiac output have been more easily obtained than volume, and only in recent years have methods been developed for the estim...

Angiographic volume estimation of right ventricle. Re-evaluation of the previous methods.

Previous angiographic methods for volume estimation of the right ventricle were re-evaluated by ten cast studies as far as the positions of the right ventricular casts were concerned. The spatial orientation of the right ventricular chamber cavity varies clockwise or counterclockwise, in the normal heart. For right ventricular volume estimation, it is important to analyze the right ventricular ...
