Insights
Coronary ectasia, a dilation of coronary arteries, was found in 1.86% of patients. Diffuse lesions were most common, and isolated ectasia correlated with atypical angina presentation.
Area of Science:
- Cardiology
- Vascular Biology
Background:
- Coronary artery disease (CAD) is a leading cause of mortality worldwide.
- Coronary ectasia, characterized by abnormal dilation of coronary arteries, is a less common finding.
- Understanding the prevalence, morphology, and clinical associations of coronary ectasia is crucial for patient management.
Purpose of the Study:
- To determine the prevalence and characteristics of coronary ectasia.
- To classify ectatic lesions based on morphology.
- To investigate the clinical presentation of patients with coronary ectasia, particularly isolated forms.
Main Methods:
- Retrospective review of 3,693 coronary angiographies.
- Identification and evaluation of patients with coronary ectasia.
- Classification of ectasia lesions using Ducceschi's morphological criteria.
- Analysis of clinical data, including angina presentation.
Main Results:
- Coronary ectasia was identified in 69 patients (1.86%) out of 3,693 angiographies.
- A total of 96 ectasia lesions were found, with the right coronary artery being the most common site.
- Diffuse lesions were the most prevalent morphological type.
- Patients with isolated ectasia showed a significantly higher incidence of atypical angina presentation.
Conclusions:
- Coronary ectasia is an uncommon finding in patients undergoing coronary angiography for suspected CAD.
- The right coronary artery is the most frequently affected vessel.
- Morphological classification reveals diffuse lesions as the predominant type.
- Isolated coronary ectasia may present with atypical angina, warranting further clinical investigation.
Abstract:
In a review of 3,693 coronary angiographies carried out in our department for suspected coronary artery disease we evaluated the 69 patients (1.86%) in whom lesions of coronary ectasia were found. Most of them (n = 51) had associated stenotic lesions and only 18 patients had isolated ectasia. The most common localization of the 96 ectasia lesions found in these patients was the right coronary artery, followed by the left anterior descending and, finally, the circumflex coronary artery. The ectasia lesions were classified according to the morphological classification proposed by Ducceschi in the following types: I) fusiform; II) saccular; III) spherical; IV) linear or diffuse, and V) mixed. Most lesions in our series were diffuse. Regarding clinical features, significant differences were found in the higher incidence of atypical angina presentation in those patients with isolated ectasia lesions.
