With the emergence of high-resolution computed tomography angiography, the number of transcatheter pulmonary arteriograms being performed has steeply declined. For this reason, many interventional departments no longer stock dedicated pulmonary artery catheters such as the pre-shaped 7 Fr Grollman catheter for a femoral vein approach. Interventionalists are therefore required to improvise with catheters that are available on hand. Transcatheter pulmonary arteriography may be indicated when dedicated pulmonary artery catheters are not available for use. In this chapter, a step-by-step approach is described and accompanied by illustrations demonstrating how a common diagnostic catheter, the 5 Fr Omniflush catheter, can be used to perform pulmonary arteriography.
