In this multicenter randomized controlled trial, routine real-time US guidance improved CFA cannulation only in patients with high CFA bifurcations but reduced the number of attempts, time to access, risk of venipunctures, and vascular complications in femoral arterial access. (Femoral Arterial Access With Ultrasound Trial [FAUST]; NCT00667381).

We report a case of coronary slow flow phenomenon (CSFP) in a patient who underwent coronary angiography due to anginal chest pain, and recurrent syncope with complete normalization of flow after intracoronary adenosine. The patient was noted to have multiple episodes of nonsustained ventricular tachycardia (VT) on holter monitor and increased QTc dispersion on surface electrocardiogram (ECG). He responded very well to oral dipyridamole therapy with complete resolution of his symptoms and no episodes of VT on the event recorder at 3 mo. We reviewed the diagnosis and clinical features of CSFP and its association with increased QTc dispersion, and the role of oral dipyridamole therapy in this condition.
