[Severe coronary artery disease and severely impaired renal function. Focused fluid expansion and ultra-low dose contrast medium administration]

The management of patients with severe coronary artery disease and severely impaired renal function may be challenging. In this report, we describe the case of a 75-year-old patient who underwent complex percutaneous coronary intervention with an ultra-low dose contrast medium protocol. Notably, the patient was scheduled for the procedure after careful monitoring of fluid expansion as assessed by echocardiography. No contrast-induced nephropathy developed and the patient was discharged safely.
