Intravenous vs. left ventricular injection of ionic contrast material: hemodynamic implications for digital subtraction angiography

Systemic, Pulmonary and Renal Haemodynamic Effects of Large Intravenous Doses of High and Low Osmolar Contrast Media; An Investigation in the Pig of Ratio 1.5 and Ratio 3 Media

“…The haemodynamic effects of contrast media have been evaluated in several experimental and clinical studies (2,3,20,22,27,30). The results of these studies are not in all aspects comparable with each other or with findings in the present study because of different types and amounts of contrast media injected, different sites and rates of injection and because different haemodynamic variables were measured.…”

Hemodynamic Effects of Monomeric Nonionic Contrast Media in Pulmonary Angiography in Chronic Thromboembolic Pulmonary Hypertension

“…There might be some concerns with respect to angiographic workup because of past reports of deleterious changes of pulmonary circulation in such patients, including considerable deterioration of right heart hemodynamics and fatality during contrast injections [8][9][10][11][12]. However, these older contrast media have been replaced by newer and safer ones.…”

Safety and Hemodynamic Effects of Pulmonary Angiography in Patients with Pulmonary Hypertension: 10-Year Single-Center Experience

“…Some investigators have observed that contrast material increases pulmonary artery pressure via a large increase in cardiac output resulting from decreased systemic vascular resistance, in spite of a concomitant decrease in PVR [25,26]. Others, however, have observed that the increased pulmonary artery pressure was due to a sustained increase in PVR after an immediate initial decrease in PVR [27].…”
