PTCA is widely practiced and has risks, but major procedural complications are rare.
Context: Dynamic Coronary Roadmap (DCR, Philips Healthcare, The Netherlands) is a novel technology that allows the users to see a moving roadmap of the coronary anatomy displayed on top of live fluoroscopy to provide guidance during navigation and positioning of devices.
Aims: Comparative study of PCI using dynamic coronary roadmap vs. PCI without using dynamic coronary roadmap on radiation dose, contrast volume and fluoroscopy time. Settings and Design: cross-sectional observational design was conducted in the tertiary care hospital.
Methods and Material: Three hundred and thirty-eight patients who underwent Percutaneous Coronary Angioplasty were enrolled. Patients were divided in DCR group and non DCR group. Statistical analysis used: Microsoft Excel and p value was calculated from online software.
Results: The 169 coronary angioplasty procedures performed with dynamic coronary roadmap resulted in a 2 % reduction in the average DAP compared with the 169 procedures performed without dynamic coronary roadmap. DCR vs without DCR (DCR: 148.7+_ 11.6 Gycm2 vs. PCI without DCR: 151.4 +_ 12.3 Gycm2, p, 0.003). In the subgroup who had primary angioplasty, patients without DCR had a 7 % increase in the mean contrast volume (DCR: 65.8 +-6.8 vs. No DCR 70.5+-8.2, p, 0.01).
Conclusions: This study found the use of DCR imaging to impart a significantly lower radiation exposure to the patient, shorter procedural time and contrast volume.
