Abstract

Background: Isolated Coronary Artery Ectasia (CAE), is considered an uncommon angiographic finding with varying pattern of presentations and carries significant morbidity burden to the patient. Aim: Evaluate the prevalence, its clinical, angiographic, and follow up characteristics. Materials and Methods: Search was done for angiograms with diagnosis of ectasia from 2012-2019. These angiograms were studied and classified as per Markis. Corresponding clinical and lab parameters were gathered from electronic medical record. Data on recurrent chest pain, unstable angina, MI, hospital admission for any cause, were collected from hospital medical records, by OPD encounters on follow up and by telephonic questionnaire. Results: The mean age was 60 years +/- 10.5 years Most common age bracket is 60-80 years (48%), with male to female ratio of 2.5 :1. Out of total 15, 634 angiograms done during the period from 2012 to 2019, 348 angiograms were found to be cases with isolated CAE or CAE with mild CAD. Ectasia with significant CAD were excluded from the study. The prevalence in the present study is 2.2 %. Most common vessel involved was LAD in diffuse coronopathy, but isolated involvement is more common in RCA. Markis class III with diffuse involvement is the most common. The mean follow up was 60 months during which 5 patients had angioplasty, other 2 patients developed thrombotic occlusion, and other 3 patients had mild disease. 4 patients died during follow up. Conclusion: Ectasia with mild CAD may not be completely innocuous and aggressive risk stratification is needed.
