ABSTRACT
Background: The right coronary artery (RCA) arises from the left sinus in an anomalous manner is an infrequent condition. Even though, many reports have centered on coronary artery anomalies, pattern of the anomalous origin of the right coronary artery (AORCA) has not well established. As far as literature is concerned, this is the first study that shed a light on the prevalence of origination and course of anomalies of RCA in the Indian population.
Materials and methods: This retrospective, observational study was conducted in tertiary healthcare center of India during the period of June 2018 to June 2020. A total of 8021 patients with suspicious or presumed development of coronary artery disease were enrolled in the study. Data regarding baseline demographics, past medical history, and origin of the anomalous RCA were collected from medical records.
Results: AORCA was more common in males (68%) than females (32%).The events of AORCA were present in 3.8% of total cases. Diabetes mellitus (43%) was the most common risk factor associated with the progression of anomalies of RCA, followed by hypertension (38%) and smoking (18%). RCA anomalies with very high origin were present in 1.15% of total cases, followed by low origin in 1.03%, and posterior origin in 0.93%.
Conclusion: The prevalence of AORCA among the Indian population has been higher than that reported in other parts of the world. Patients with the anomalies of RCA from the left sinus suffer from syncope, cardiac arrhythmias, and myocardial ischemia and infarction. In terms of origin and clinical significance, proper understanding in regards to the anomalies of RCA is crucial for making the correct diagnosis, and further planning for treatment.
