Introduction
Coronary artery anomalies are rare congenital abnormalities often found incidentally on conventional coronary angio-gram or coronary computed tomography angiography. They may result in various clinical outcomes. The objective of this study was to investigate the prevalence of coronary artery anomalies, the clinical and laboratory characteristics of patients with coronary artery anomalies, and the outcomes at five-year follow-up of these patients in a high-volume coronary interventional center in Romania.
Materials and Methods
To define the study population we reviewed all coronary angiograms performed between 01.01.2014 and 31.12.2014. A total number of 5832 coronary angiograms were analyzed, and we identified 31 patients with coronary artery anomalies.
Results
The prevalence of coronary artery anomalies was 0.53%. Eighty-seven point four percent of the patients had origin and distribution anomalies, and twelve point nine percent of the patients had a coronary artery fistula. The most common coronary artery anomalies were the anomalous origin of the right coronary artery and the anomalous origin of the left circumflex artery from the initial segment of the right coronary artery. Sixty-one point three percent of the patients underwent coronary angiogram due to atypical chest pain. Twenty-nine percent of the patients had significant coronary artery disease. No death or significant complication were recorded in the 31 patients during the 5 years follow-up.
Conclusions
The prevalence of coronary artery anomalies in this study was slightly lower but still like that of previous studies. The majority of patients presented with atypical symptoms, and only a minority had coronary artery disease. In the context of no death or significant complication at 5-year follow-up highlights the benign prognosis of most coronary artery anomalies.
