[Intravenous digital subtraction ventriculography: technical and methodologic aspects, a comparison with...

Intravenous digital subtraction ventriculography (IDSV) was performed in 294 patients with various pathology. The IDSV method and conditions for obtaining informative ventriculograms were described. Hemodynamic indices and LV segmental contractility were assessed. IDSV and CVG data were compared in 52 cases. The results of both methods showed high correlation, IDSV having advantages over CVG (the absence of a cardiosuppressive effect resulting from direct administration of a contrast medium into the LV chamber and excluding LV quantitative overload). IDSV as a semiinvasive and easy-to-perform method has no contraindications.
