Abstract

Aims: Despite the widespread use of the radial approach in coronary interventions, left ventricular endomyocardial biopsy (LV-EMB) is most frequently performed via the femoral artery. We sought to assess the feasibility and safety of radial compared to femoral access in a large cohort of patients undergoing LV-EMB. Methods and results: Data from 264 patients who underwent LV-EMB in Germany, Portugal, Japan and Canada were collected. Clinical, procedural, safety and feasibility data were evaluated and compared between the two groups. LV-EMB was successfully performed by the radial approach in 129 (99%) of 130 and in 134 (100%) patients by the femoral access. Patients in the radial group were older (mean age 55.7 versus 44.3 years) and were more likely to have moderate-severe mitral regurgitation (27.7% versus TF 0%). Sheathless guides were used in 108 (83.1%) of the radial and 2 (1.5%) of the femoral patients, so the mean guiding catheter size (radial 7.0±1.0 Fr versus femoral 8.0±0.0 Fr) was significantly smaller in the radial group (p<0.001). Mild or moderate radial artery spasm occurred in 13 (10.0%) patients but only one (0.8%) patient required conversion to femoral access due to severe spasm. No access site-related complications were reported in the radial group, while 11 (8.2%) patients in the femoral group had access-site haematomas (p=0.001). There were no major complications (mitral valve injury, pericardial tamponade requiring intervention, cerebrovascular accidents, persistent high-degree atrioventricular block, major bleeding or death) in either group. Conclusions: The radial approach for LV-EMB appears to be safe and associated with a high success rate while possibly leading to fewer access-site bleeding complications compared to the femoral access. The results of this international multicentre study support the radial approach for LV-EMB and further inspire the expansion of "radial first"in the field of interventional cardiology.
