The incidence of contrast-induced nephropathy (CIN) is high (\> 25%) in patients with severe chronic renal disease (CKD) who undergo a percutaneous coronary procedure. The development of CIN is a factor of poor prognosis and is associated with the occurrence of irreversible CKD, the need for dialysis, increased length of stay and hospital costs as well as the risk of death. There is no specific treatment for N-PCI, so its prevention is essential. Although many studies have been conducted to identify, compare and implement different pharmacological strategies for the prevention of CIN before percutaneous coronary procedurse, few per-procedural strategies have been studied to prevent this risk. Intracoronary ultrasound (IVUS) is an essential tool, used routinely to guide percutaneous coronary procedures thanks to ultrasound, it does not require the injection of iodine contrast. The main objective is to show that an IVUS-guided "zero-contrast" coronary angioplasty strategy in patients with severe renal impairment decreases the incidence of CIN within 72 hours of procedure.

RECRUITINGRate of serum creatinine due to nephropathy
Contrast-induced nephropathy is defined as an increase in creatininemia by 25% from its baseline level. The parameter being measured is creatininemia, which refers to the concentration of creatinine in the blood. The unit of measurement for this increase is a percentage (%)
Time frame: 30 days
Global safety
The occurrence of death from any cause within 30 days. The unit of measurement is the presence or absence of death.
Time frame: 30 days
Endocoronary complications
his includes dissection, thrombus formation, breaches, or coronary occlusion that require an additional unplanned intervention. The unit of measurement is the occurrence of these complications, recorded as Yes or No.
Time frame: 72 hours
Procedural Criteria
Procedure time: The total time taken for the procedure. The unit of measurement is time, typically recorded in minutes (min)
Time frame: 72 hours
Myocardial infarction
The occurrence of a myocardial infarction within 30 days. The unit of measurement is the presence or absence of the event, recorded as Yes or No."
Time frame: 30 days
Global safety : stroke
Stroke: The occurrence of a stroke within 30 days. The unit of measurement is the presence or absence of the event, recorded as Yes or No
Time frame: 30 days
Global safety
Unplanned hospitalization for cardiac or renal causes: The occurrence of an unplanned hospitalization due to cardiac or renal causes within 30 days. The unit of measurement is the presence or absence of the event, recorded as Yes or No.
Time frame: 30 days
Angioplasty failures
Angioplasty failures are defined by a residual stenosis of 70% or greater and/or a TIMI flow of less than 3 at the end of the procedure. The unit of measurement for residual stenosis is percentage (%) and for TIMI flow, the unit is a scale from 0 to 3, with a TIMI flow of less than 3 indicating failure.
Time frame: 72 hours
Procedural Criteria : Fluoroscopy time
Fluoroscopy time: The amount of time fluoroscopy imaging is used during the procedure. The unit of measurement is time, typically recorded in minutes (min)
Time frame: 72 hours
Procedural Criteria: Air Kerma
Air Kerma: A measure of the radiation dose delivered during the procedure. The unit of measurement is the Gray (Gy), specifically milligray (mGy) for this context
Time frame: 72 hours
Procedural Criteria : PDS (Procedure Dose Score)
PDS (Procedure Dose Score): A measure of the total radiation dose delivered to the patient during the procedure. The unit of measurement is arbitrary units based on the specific scoring system used.
Time frame: 72 hours
Procedural Criteria
Volume of contrast injected: The amount of contrast material used during the procedure. The unit of measurement is milliliters (mL)
Time frame: 72 hours
