Transradial Approach, clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT02034084 Completed - Clinical trials for Percutaneous Coronary

A Comparison of Left and Right Radial Approach for Percutaneous Coronary Procedures

Start date: March 2011
Phase: N/A
Study type: Interventional

Previous studies have shown that the transradial cardiac catheterization has decreased not only bleeding complications related to the access site and procedural discomfort but also morbidity and hospitalization as compared to transfemoral approach. At present, the right radial approach (RRA) is the first choice routinely for coronary angiography and interventions in daily clinical practice despite more marked subclavian artery tortuosity than left radial approach (LRA). Although LRA has been thought to be more direct access to the ascending aorta similar to transfemoral approach and may reduce fluoroscopy time and cerebrovascular complications compared with RRA, the application of LRA for coronary intervention is still low. Moreover, several studies have also obtained conflicting results showing no difference in procedural success rate compared LRA and RRA using Judkins catheters. To date, it remains unclear whether LRA is superior to RRA in term of safety and feasibility for coronary angiography and interventions in real world practice and few data of randomized control trial are available. The aim of this study was to randomly investigate and compare the safety and feasibility of LRA compared with RRA for coronary diagnostic angiography in Chinese subjects. The investigators will enroll consecutively for 2 years all patients undergoing coronary diagnostic procedures through trans radial approach. The primary outcome was total procedural duration. Secondary outcomes included fluoroscopy time, dose of radiation including cumulative air kerma and dose area product, contrast volume and the incidence of vascular complications.
