When calcium helps: percutaneous coronary intervention without contrast medium in an elderly female patient with renal insufficiency and unstable angina
The use of iodinated contrast media in coronary procedures may lead to contrast-induced nephropathy – particularly in older adults, diabetic individuals and patients with previous renal disease – and increase morbidity and mortality. There is no specific treatment for this condition; therefore, use of low contrast volumes and previous hydration remain the best prevention strategies. A case of percutaneous coronary intervention without contrast agent administration, involving an elderly female patient with chronic renal insufficiency and stable angina, is described. Intravascular ultrasound was used for optimal stent deployment.
