Duration of storage of digital cine images is often mandated by law. Operating parameters for x-ray imaging equipment are adjusted at installation and periodically assessed by a qualified physicist in cooperation with the equipment manufacturer. Familiarity with radiation dose reducing features of catheterization lab- oratory equipment and assistance from a qualified physicist are important for radiation dose minimization and image optimization. An interventional cardiologist must be present in the labora- tory for the duration of each procedure and is responsible for Table 4. Summary of Recommendations for Preprocedural Considerations and Interventions in Patients Undergoing PCI Recommendations COR LOE References Contrast-induced AKI Patients should be assessed for risk of contrast-induced AKI before PCI. I C 270,271 Patients undergoing cardiac catheterization with contrast media should receive adequate preparatory hydration. I B 272 275 In patients with CKD (creatinine clearance 60 mL/min), the volume of contrast media should be minimized. I B 276 278 Administration of N-acetyl-L-cysteine is not useful for the prevention of contrast-induced AKI. III: No Benefit A 279 283 Anaphylactoid reactions Patients with prior evidence of an anaphylactoid reaction to contrast media should receive appropriate prophylaxis before repeat contrast administration. I B 252,284 286 In patients with a prior history of allergic reactions to shellfish or seafood, anaphylactoid prophylaxis for contrast reaction is not beneficial. III: No Benefit C 287 289 Statins Administration of a high-dose statin is reasonable before PCI to reduce the risk of periprocedural MI. IIa A: Statin na ve 290 296 B: Chronic statin therapy Bleeding risk All patients should be evaluated for risk of bleeding before PCI. I C N/A CKD In patients undergoing PCI, the glomerular filtration rate should be estimated and the dosage of renally cleared medications should be adjusted.
