Unprotected Left Main Primary PCI via Distal Transradial Access in the Setting of STEMI-Related Cardiogenic Shock.

Despite all well-known benefits of transradial access, patients presenting with cardiogenic shock are usually submitted to coronary angiography and percutaneous coronary intervention via traditional transfemoral access, mainly due to challenge puncture of radial artery in the setting of hemodynamic instability. We report a challenging case of STEMI-related cardiogenic shock requiring primary PCI of an occluded and unprotected left main, safety, and successfully performed via right distal trans radial access in the anatomical snuffbox.
