Experience with Four French Catheters for Outpatient Coronary Angiography.

Previous studies have demonstrated the efficacy and safety of outpatient cardiac catheterization on stable patients at low risk. We present our experience with four French catheters in 104 patients (72 male, 32 female, mean age 51 years old) with coronary angiography done as an outpatient procedure. No heparin was given during the procedure. After initial hemostasis had been attained, the patients returned to day center with vital signs monitored regularly. Patients were allowed ambulation after 4 hours' bed rest and were discharged the same afternoon. Normal coronary angiogram study was found in 76% of the study population. Single-vessel disease, double-vessel disease, triple-vessel disease, and left-main disease were found in 12%, 9.6%, 2%, and 1%, respectively. Nearly all of the patients demonstrated normal ventricular contraction (99%). Average procedural time was 20.2±4.4 minutes. Average hemostatic time was 8.4±3.1 minutes. No mortality directly attributed to the catheterization occurred in our study population. Moreover, there were no myocardial infarction, acute pulmonary edema, severe allergic reaction, and cerebrovascular accident. Femoral puncture site complication was only limited to superficial skin bruise. Quality of the cineangiogram was good in majority of the patients. Therefore, this study demonstrates that outpatient cardiac catheterization using four French Judkins catheter is a safe and cost-effective procedure.
