Application of digital echocardiographic images during cardiac catheterization

During cardiac catheterization left ventricular angiograms are frequently performed to assess left ventricular function. In a substantial percentage, on line available echocardiographic images may be considered as a clinical substitute for left ventricular angiograms. The potential advantages include: (1) Less complications. Avoiding a left ventricular angiogram causes reduction of the amount of contrast fluid used and reduction of the total radiation exposure, leading to less complications such as deterioration of renal function. (2) Lower costs due to reduction in the use of angiographic materials such as catheters, syringes and contrast fluid and shorter procedural time.
