Pre-Procedural Preparations for Heart Catheterization

Patient Assessment and Preparation

The American College of Cardiology recommends that the physician performing the catheterization must thoroughly review the patient's history, physical examination, and pertinent laboratory data before the procedure, ideally the day before when possible 1, 2
The American College of Cardiology suggests that the procedure should be timed when conditions such as arrhythmias, congestive heart failure, or azotemia are stable or improving to avoid misleading physiological data and increased procedural risks 1, 2
The American College of Cardiology states that informed consent must be obtained by the physician performing the procedure, with a detailed discussion of the reasons for the study, potential benefits, complications, and a description of the examination 1, 2

The American Heart Association recommends that all patients should be evaluated for bleeding risk before the procedure 3
The American Heart Association suggests that glomerular filtration rate should be estimated, and dosages of renally cleared medications should be adjusted accordingly 3
The American Heart Association states that patients should be assessed for risk of contrast-induced acute kidney injury (AKI) before the procedure 3
The American Heart Association recommends that in patients with chronic kidney disease (creatinine clearance <60 mL/min), the volume of contrast media should be minimized 3

The European Society of Cardiology recommends that for patients on oral anticoagulants, management depends on the type of anticoagulant, with warfarin able to be continued at modified doses for most cardiac catheterizations 4
The European Society of Cardiology suggests that for trans-septal catheterization, direct LV puncture, or pericardial drainage, oral anticoagulants should be stopped and bridging anticoagulation performed 4
The European Society of Cardiology states that when bridging is required, the last dose of low molecular weight heparin (LMWH) should be administered >12 hours before the procedure, while unfractionated heparin (UFH) should be discontinued 4 hours before surgery 4
The European Society of Cardiology recommends that effective anticoagulation should be resumed as soon as possible after the procedure according to bleeding risk 4

The American Heart Association recommends that patients already on daily aspirin therapy should take 81 mg to 325 mg before the procedure 3
The American Heart Association suggests that patients not on aspirin therapy should be given non-enteric aspirin 325 mg before the procedure 3
The American Heart Association states that for patients requiring high-dose statins, administration before the procedure is reasonable to reduce the risk of periprocedural myocardial infarction 3

The American Heart Association recommends that all patients undergoing cardiac catheterization with contrast media should receive adequate preparatory hydration to prevent contrast-induced nephropathy 3
The American Heart Association states that administration of N-acetyl-L-cysteine is not useful for the prevention of contrast-induced AKI 3

The American Heart Association recommends that patients with prior evidence of anaphylactoid reaction to contrast media should receive appropriate prophylaxis before repeat contrast administration 3
The American Heart Association states that in patients with a history of allergic reactions to shellfish or seafood, anaphylactoid prophylaxis for contrast reaction is not beneficial 3

The American College of Cardiology recommends that protection measures for both patients and staff should be implemented, including appropriate personal protective equipment such as gloves, gowns, and laboratory coats 1, 2
The American College of Cardiology suggests that for more complex and lengthy procedures, more rigorous sterile technique should be followed 1, 2
The American College of Cardiology states that heparin should be routinely administered when nonionic contrast agents are used for angiography, as these agents inhibit blood clotting and platelet aggregation less than ionic agents 1, 2

The American College of Cardiology recommends that standard post-procedural orders should include checking and recording blood pressure, pulse, distal pulses, and status of bandage sites every 15-30 minutes for 2 hours, then every hour for several hours 1, 2
The American College of Cardiology suggests that a member of the catheterization team should examine the patient later in the day and subsequently as indicated 1, 2
The American College of Cardiology states that an adequate post-procedural holding area should be available, especially for patients undergoing ambulatory catheterization 1, 2

The American Heart Association states that inadequate hydration before contrast administration increases the risk of contrast-induced nephropathy 3
The European Society of Cardiology recommends that improper management of anticoagulation, particularly when bridging is required, should be avoided 4
The American Heart Association suggests that overlooking the need for bleeding avoidance strategies such as radial artery access can reduce access-related bleeding and complications compared to femoral access 3
