Transradial Angiography with Dedicated Catheter: A Tertiary Care Center Experience

Objective: To demonstrate the safety and feasibility of tiger catheter for trans-radialcoronary angiography. Methodology: It was a retrospective observational study conducted at the Peshawar Institute of Cardiology. A total of 2728 patients were included over a period of 1 year, from Apr 01, 2021, to Mar 31, 2022, who underwent radial angiography with a tiger catheter. All data was collected through the hospital database. Angiography clips were analyzed by senior consultant cardiologists for the occurrence of any complications. Results: Among 2728 patients, 60.63% of patients were males, and 39,36% were females. The mean fluoroscopy time was 0.85±0.36 minutes. The mean contrast volume used was 33.33±10.19 ml. The rate of any major complication was extremely low. Radial artery spasm was the most common complication and occurred in 3.9% of cases. Coronary artery ostial dissection occurred in only 4 cases, and all were successfully stented. Switching over to Judkins left (1.94%) and Judkins right (1.76%) catheter in cases of difficult engagement was also very low. Conclusion: Our study has demonstrated that radial angiography performed with a Tiger catheter is associated with low contrast volume and fluoroscopy time and an extremely low rate of any major complication.
