Abstract

Accurate ventricular pressure measurements are essential in many experimental procedures. However, obtaining this information in the chronic animal is either very expensive or plagued with uncertainties. This paper describes a method for implanting a chronic ventricular catheter which permits the repeated insertion into the left ventricle of a miniature pressure transducer. Since only one such transducer is required it reduces expense and as the transducer is not chronically implanted, it permits repeated calibration, thus eliminating the uncertainty of transducer drift. This procedure has been used successfully in chronically prepared dogs and promises to be a useful technique in working with conscious animals.
