Letter by Pristipino and Hamon Regarding Article, “Cerebral Microembolism During Coronary Angiography: A Randomized Comparison Between Femoral and Radial Arterial Access”

To the Editor:We read with interest the article by Jurga et al1 reporting the results of a small randomized study in which the main finding is the higher incidence of particulate microemboli after right transradial access as compared with transfemoral access.We think that the results of the study should be interpreted with caution for the following reasons.First, transradial catheterization is a challenging technique requiring a steep learning curve and a high volume of procedures to maintain the procedural performance. Indeed, the duration and outcomes of radial procedures may significantly differ according to the expertise of operators.2 The marked difference in fluoroscopy times between …
