While there is a trend toward less bleeding in the pts ≥ 75 years oldWith the radial approach, it does not reach statistical significance.This underscores the importance of non-access site bleeding

Issues specific to transradial in elderly patients

Tortuosity of arm and chest vessels Low threshold for angiography Deep breath to direct wire Get experience with other catheter curves

Complex PCI – few limitations with currently available 6Fr guiding catheters used via the transradial approach

Transradial PCI in the elderlyConclusions (1)

PCI-related ischemic outcomes have improved in older patients High rates of procedure success Low rates of peri-PCI ischemic events

Reducing bleeding risk is the priority Transradial is associated with reduced bleeding

risk, but… Crossover to femoral may be higher Non-access site related bleeding is important in

older patients

Strategies for reducing bleeding risk in older pateints include: Transradial Pharmacological therapies – appropriate dosing,

alternative antithrombin strategies Transradial tips/tricks

Low threshold for forearm/chest angiography Deep breath to direct equipment Use of other guide catheter curves New technology coming
