Introduction

Coronary slow flow phenomenon is a angiographic entity characterized by delayed progression of the injected contrast through the coronary arteries, without any flow limiting lesions incidence is 1.7% of all Coronary Angiograms.   

This can manifest as myocardial ischemia, life threatening arrhythmias, sudden cardiac death, recurrent ACS.

This CSFP may be primary, secondary. Secondary causes are coronary artery ectasia, coronary spasm, valvular heart disease, connective tissue disorder etc.
