Outpatient coronary angiography with 4 French catheters.
The early 4 French (Fr), pre-formed, Judkins coronary catheters had unsatisfactory maneuverability due to reduced torque stability. Technical innovations have led to improved 4 Fr catheters. This prospective study evaluates the safety and feasibility of the 4 Fr Quick Care Infinity catheter (Cordis, Miami, Florida). Within a series of 2,366 patients investigated for suspected coronary artery disease, 302 were selected for outpatient treatment according to the guidelines for outpatient catheterization. Fluoroscopy time was 2.8 +/- 2.5 minutes. It was not necessary to change to larger catheters in any patient. After sheath removal, hemostasis was achieved within 14 +/- 8 minutes. Strict bed rest lasted 181 +/- 65 minutes; patients were discharged 303 +/- 76 minutes after arterial puncture. Sixteen of the 302 patients (5.3%; 95% confidence interval (CI): 3.1-7.9%) changed to inpatient treatment for reasons unrelated to the arterial access. Eight patients (2.6%; CI: 1.1-5.1%) required one night of hospitalization for control of hematoma. The following morning, vessel murmur, pain, and large hematoma (more than 10 cm diameter) occurred in 1 (0.3%), 6 (2.0%), and 6 (2.0%) patients, respectively. This necessitated hospital admission in 2 patients (0.7%; CI: 0.0-2.3%) for up to 2 days. Major entry site complications requiring blood transfusion or surgery did not occur (CI: 0.0-0.3%). It was concluded that outpatient catheterization for coronary artery disease using the new 4 French catheters is feasible and can be rapidly and safely performed in a selected patient population.
