Incidence, Determinants, and Outcomes of Left and Right Radial Access Use in Patients Undergoing Percutaneous Coronary Intervention in the United Kingdom: A National Perspective Using the BCIS Dataset

Abstract

OBJECTIVES:

The authors sought to determine the relationships between left radial access (LRA) or right radial access (RRA) and clinical outcomes using the British Cardiovascular Intervention Society (BCIS) database.

BACKGROUND:

LRA has been shown to offer procedural advantages over RRA in percutaneous coronary intervention (PCI) although few data exist from a national perspective around its use and association with clinical outcomes.

METHODS:

The authors investigated the relationship between use of LRA or RRA and clinical outcomes of in-hospital or 30-day mortality, major adverse cardiovascular events (MACE), in-hospital stroke, and major bleeding complications in patients undergoing PCI between 2007 and 2014.

RESULTS:

Of 342,806 cases identified, 328,495 (96%) were RRA and 14,311 (4%) were LRA. Use of LRA increased from 3.2% to 4.6% from 2007 to 2014. In patients undergoing a repeat PCI procedure, the use of RRA dropped to 72% at the second procedure and was even lower in females (65%) and patients >75 years of age (70%). Use of LRA (compared with RRA) was not associated with significant differences in in-hospital mortality (odds ratio [OR]: 1.19, 95% confidence interval [CI]: 0.90 to 1.57; p = 0.20), 30-day mortality (OR: 1.17, 95% CI: 0.93 to 1.74; p = 0.16), MACE (OR: 1.06, 95% CI: 0.86 to 1.32; p = 0.56), or major bleeding (OR: 1.22, 95% CI: 0.87 to 1.77; p = 0.24). In propensity match analysis, LRA was associated with a significant decrease in in-hospital stroke (OR: 0.52, 95% CI: 0.37 to 0.82; p = 0.005).

CONCLUSIONS:

In this large PCI database, use of LRA is limited compared with RRA but conveys no increased risk of adverse outcomes, but may be associated with a reduction in PCI-related stroke complications.
