Background We have begun to perform routine and research MRI right heart catheterization in adults and research MRI catheterization in children. We report our technologist workflow. Methods Scanner preparation: The scanner façade and bore are covered with adhesive clear sterile drapes and surface coils enveloped in sterile plastic bags. A MR catheterization pack contains only non-ferromagnetic ...

Cardiac catheterization was done for the first time 25 years ago by Forssman,’ who performed the maneuver on himself. However, this procedure was employed in the study and diagnosis of heart disease only after Cournand and Ranges2 demonstrated the value and safety of the method in 1941. The method was subsequently completed by the addition of several collateral techniques. The most useful appli...

*From the Department of Medicine, University of Minnesota Medical School, Minneapolis, Minnesota. Supported in part by grants from the Public Health Service HE-5222 and 06314. this has not been reported during left heart catheterization. This report concerns a patient who developed acute myocardial infarction and severe left ventricular failure during diagnostic left heart catheterization. Inju...

A method of transseptal catheterization of the left side of the heart via the right subclavian vein has been described. It was attempted in 29 patients and the left atrium was entered in 26 patients. The left ventricle was entered in 2I of the 23 patients (9I%) where entry was attempted. The risks and advantages of this technique have been discussed. It is a useful additional method for cathete...

OBJECTIVE A reliable and easy-to-perform method for measuring right ventricular (RV) afterload is desirable when scheduling patients with systolic heart failure to undergo heart transplantation. The present study aimed to investigate the accuracy of echocardiographically-derived pulmonary arterial elastance as a measurement of pulmonary vascular resistance by comparing it with invasive measures...

Twenty-six adult patients were studied by coimbined right and left heart catheterization to define or further to quantitate valvular defects suspected on clinical grounds. Right heart catheterization was accomplished in the usual fashion from an antecubital vein and the left heart was studied by combined transseptal left atrial and retrograde left ventricular catheterization.4 By use of these m...
