In an elegant original manuscript Merella et al. [ 1 ] describe the benefits of 2 methods of “arterial tracking” (AT) to facilitate transradial (TR) interventions. The authors suggest balloon-assisted tracking (BAT [ 2 ]) and pigtail-assisted tracking (PAT [ 3 ]) as tools to facilitate the TR advancement of 5F (10.4%) and 6F (89.6%) guiding catheters for PCI. These methods should be part of the toolbox for any interventionalist because their use enhances TR or transulnar (TU) success rates and probably reduces the likelihood of vascular complications and patient discomfort caused by advancement of guiding catheters over 0.035″ wires. The authors report progressive success executing same-site TR-PCI over the years for those who adopted BAT and PAT (69.5%, 79.3% 87.1%, and 98.3% for the years 2016, 2017, 2018, and 2019, respectively). They also show the superiority of AT users versus non-users in attaining high rates of TR-PCI (98.3% versus 89%, P < 0.001). This retrospective report is lacking some relevant information including: patient comfort and satisfaction, procedure time, equipment and contrast use, and long-term-access artery patency.
