Current updated guidelines recommend the use of radial approach rather than femoral approach in terms of immediate ambulation, less bleeding complication and reduced mortality rate. Recently, the left distal transradial approach (ldTRA) has been introduced as an alternative for feasibility and safety while satisfying both patient and operator convenience. However, there are few studies related to ldTRA. The purpose of this prospective observational study is to assess the feasibility and safety of the ldTRA for coronary angiography (CAG) and percutaneous coronary intervention (PCI).
Two hundred patients with palpable left distal radial arteries and need to perform CAG or ad hoc PCI were prospectively enrolled. Co-primary endpoints were the success rate and complication rate of CAG and PCI via ldTRA.
Fifty-six patients were enrolled during 4weeks. Mean age was 64.3±13.3 years (median: 62) and there were more men (n=38, 67.9%) than women (n=18, 32.1%). Acute coronary syndrome (myocardial infarction: n=18, 32.2%; unstable angina: n=19, 33.9%) was the most common condition, followed by stable angina (n=7, 12.5%). Ad hoc PCI was n=29 (52%), and only diagnostic CAG was n = 27 (48%). Two cases of puncture failure (3.57%) via ldTRA were observed. Where puncture was successful, CAG and ad hoc PCI succeeded. There were no serious bleeding complication and nerve injury.
In this ongoing prospective registry, CAG and ad hoc PCI via ldTRA showed good feasibility and safety. Updated data will be presented.
