Value of the New Dynamic Coronary Roadmap System in Percutaneous Coronary Intervention for Patients With Chronic Coronary Syndrome

Chronic ischemic heart disease is the primary cause of acute and chronic heart failure. Cardiac failure due to exacerbated coronary heart disease occurs in 1 of every 4 cases. Variable degrees of heart failure are present in two-thirds of coronary patients who undergo conventional percutaneous coronary intervention (PCI). In an attempt to lower the occurrence of acute kidney injury and contrast-induced nephropathy, the current study aimed to evaluate the effects of PCI using the new dynamic coronary roadmap (DCR) system on the contrast medium volume.
 
This observational study enrolled 80 patients undergoing PCI for chronic coronary syndromes. Patients were assigned to 2 equal groups. Group I consisted of patients who underwent the DCR technique (the DCR group), and Group II was composed of patients who underwent the normal PCI technique without DCR (the normal group). The patients had detailed history taking, comprehensive clinical examinations, the DCR system, and PCI.
 
Group II demonstrated significantly higher contrast medium volume (179  ± 62 vs 37 ± 11 mL; P < 0.001), fluoroscopy time (12 ± 3 vs 6 ± 2 min; P < 0.001), air kerma (744 ± 85 vs 285 ± 60 mGy; P < 0.001), and dose area product (47 ± 5 vs 36 ± 7 Gy/cm2). In contrast, Group I had a significantly higher estimated glomerular filtration rate post-PCI (P = 0.015).
 
Contrast volume and fluoroscopy time can be reduced by using DCR during PCI. (Iranian Heart Journal 2023; 24(4): 34-41)
