This procedure is designed to detect, define and quantitate various hemodynamic functions of the heart.  These functions include ventricular function (pumping action of the heart) including overall ejection fraction and regional contractility of the myocardium, cardiac chamber volumes and cardiac output, and detection and quantitation of intracardiac valve incompetence.  This study is useful in following changes in these quantitative parameters over a period of time.

Principle:

Gated heart imaging involves the use of a radiopharmaceutical that labels the intravascular space - such as 99mTc-tagged RBC's.  The technique is based on imaging the left ventricle for a large number of beats.  The R-wave of each beat triggers the image data division into a designated number of frames to span each beat.  This summing process continues until sufficient counts are present in each frame to permit analysis of the composite cardiac cycle.

Required scheduling information:

• Patient name, DOB, current weight and home phone.

• Reason for exam/diagnosis.
