Use of the CHA

Radial access is now considered the preferred approach for coronary angiography and percutaneous coronary intervention because of the low risk of vascular complications. However, radial access failure is not uncommon, leading to crossover to a different access site. The CHAWe performed a single-center, non-randomized, retrospective study. The study included 1775 patients who underwent coronary angiography with or without subsequent percutaneous intervention between July 2018 and October 2019. The study population was divided into three groups based on the CHAA total of 197 patients (11.1%) had crossover to the femoral artery. A large percentage of patients (19.2%) had radial access failure in the high CHAThe CHA
