Hypoplastic Left Circumflex Coronary Artery: Imaging Findings with Coronary Computed Tomography Angiography - A Case Report

<P>Background: Hypoplastic coronary artery disease is a rare congenital coronary artery anomaly. It is often detected incidentally, and its true incidence in the general population is not known. </P><P> Discussion: Symptoms of HCAD are syncope, palpitations, dyspnea, and chest pain. Also, arrhythmia and myocardial infarction can be seen; these can cause sudden death, especially in athletes and young people. Diagnosis is often made at autopsy. Conclusion: Here, we present the case of a 39-year-old male with isolated hypoplasia of the left circumflex artery detected by coronary Computed Tomography (CT) angiography who complained of palpitation.</P>

Left Circumflex Artery

The study was performed to identify the features of coronary artery calcifications with the use of coronary computed tomography angiography in patients suffering from rheumatoid arthritis. In the study, calcifications were found in one vessel in 5 (8.3%) patients, in two vessels - in 24 (40%) subjects, in three vessels - in 28 (46.7%), and in four vessels - in 3 (5%) patients. 100% of patients were diagnosed with calcifications in the left descending artery, 90.2% - in left circumflex artery, 56.9% - in right coronary artery, 9.8% - in the root of left coronary artery, 92.2% of patients were diagnosed with calcifications of the aortic arch. The highest calcium score was registered in left circumflex artery (343.5±10.0 HU), and the lowest one - in right coronary artery (262.1±17.7 HU). The study results demonstrated correlation between the stage of rheumatoid arthritis and coronary calcification. In 77.8% of patients with stage I of the disease and in all patients with stage II, III and IV, calcifications of various size and localization were revealed in coronary arteries and aortic arch. Also, the relationship between duration of the disease and calcinosis extent was revealed. The obtained results indicate the importance of coronary computed tomography angiography for the diagnosis of coronary atherosclerosis in patients with rheumatoid arthritis due to high risk of cardiovascular complications in these patients.

Artery Disease

The objective of this study was to determine how coronary computed tomography angiography (CCTA) can be employed to detect coronary artery disease in hospital employees, enabling early treatment and minimizing damage. All employees of our hospital were assessed using the Framingham Risk Score. Those with a 10-year risk of myocardial infarction or death of >10% were offered CCTA; the Coronary Artery Disease Reporting and Data System (CAD-RADS) score was the outcome. A total of 3923 hospital employees were included, and the number who had received CCTA was 309. Among these 309, 31 (10.0%) had a CAD-RADS score of 3–5, with 10 of the 31 (32.3%) requiring further cardiac catheterization; 161 (52.1%) had a score of 1–2; and 117 (37.9%) had a score of 0. In the multivariate logistic regression, only age of ≥ 55 years (p < 0.05), hypertension (p < 0.05), and hyperlipidemia (p < 0.05) were discovered to be significant risk factors for a CAD-RADS score of 3–5. Thus, regular and adequate control of chronic diseases is critical for patients, and more studies are required to be confirmed if there are more significant risk factors.
