Brief Summary:
The purpose of this study is to determine if increasing the linear rise rate of injection of x-ray contrast in the heart during left ventriculogramspart of a cardiac Catheterization procedure will decrease the incidence of arrythmias and improve image quality
Detailed Description:
The LV angiogram is performed frequently as part of the cardiac catheterization procedure It is done by injecting a bolus of x-ray contrast into the ventricle through a pigtail catheter over a short period of time and observing the heart as it is pumped out This provides information on regional wall motion abnormalities ejection fraction and mitral regurgitation A common occurrence when performing a LV angio is frequent PVCs or V-tach during the injection it has been suggested that ectopics occurs about 54 of the time and that interpretability was limited 30 of the time3 This is rarely serious and subsides at the end of the injection but the irregularity of the contractions does affect the diagnostic quality of the exam
In an attempt to decrease the incidence of ventricular ectopics during the LV angiogram Contrast injections with a greater linear rise increasing the injection duration to at least ½ the flow rate greater than previous settings should decrease the tension and the contrast jets coming out of the catheter decreasing the fling of the catheter at the initiation of the injection Whether this affects the quality of the angiogram with a pig tail vs a straight catheter will also need to be considered
