Long-term Radial Artery Occlusion in Coronary Diagnosis and Intervention Via Distal Radial Approach (CONDITION)

Comparison of the Long-term Radial Artery Occlusion in Coronary Diagnosis and Intervention Via Distal vs Conventional Radial Approach: Randomized-controlled Trial(CONDITION)

Randomized-controlled trial to comparison of the long-term radial artery occlusion in coronary diagnosis and intervention via distal vs conventional radial approach

Coronary diagnosis and intervention via distal radial artery is prevalent worldwide. This study aims to explore the long-term radial artery occlusion after coronary diagnosis and intervention via distal radial artery at 3 months after procedure using portable high-frequent ultrasound. The secondary endpoints include the success rate of puncture, time of puncture, duration of hemostasis, radial artery trauma, etc.

Inclusion Criteria:

• Age ≥ 18 years;
• Palpable unilateral distal radial and radial artery

Exclusion Criteria:

• Age ≥ 90years;
• Height≥ 185cm;
• Cardiogenic shock;
• Contraindications to puncture at the puncture site;
• Inability to obtain written informed consent
• Previous right radial or distal artery intervention
