Method for coronary angiography in morbidly obese patients.
Cardiac catheterization in morbidly obese patients is difficult. In addition to problems regarding vascular access and radiographic penetration of the chest, the engineering parameters and physical limitations of the table and its supporting structures may limit these patients' ability to undergo clinically indicated coronary angiography. We describe a method for cardiac catheterization in which much of the obese patient's body weight is supported on a stretcher placed at right angles to the catheterization table, with only the thorax on the table under the image intensifier. Using this method, five consecutive successful diagnostic procedures and one coronary stent procedure have been performed without complication. Limitations of this procedure include inability to achieve the normal variety of angiographic views due to constraints on image intensifier rotation and skew.
