We describe a case of a single coronary artery originating from the right coronary sinus and bifurcating into the left coronary artery (LCA) and right coronary artery (RCA) in a 74-year old woman, with a non-ST elevation acute myocardial infarction (NSTEMI). Diagnosis was made by coronary angiography which ruled out stenosis, and showed normal LCA and RCA branching. The connection path of LCA, with the opposite cusp, was defined retroaortic by multislice computed tomography (CT). The variants of this coronary anomaly, together with their clinical implications and pathophysiology of acute myocardial infarction (AMI) are discussed. Multislice CT is fundamental for clinical decision making.
Coronary artery anomalies, single coronary artery, multislice computed tomography; right sinus of Valsalva.

72/Electrocardiographic findings in junior athletes before and after exercise in Latvia in two year time period
European Journal of Arrhythmia & Electrophysiology. 2021;7(Suppl. 1):abstr72
Introduction: Every year two out of all children up to age eighteen die from heart problems that can be noticed by regular electrocardiography (ECG). Some of these children had been diagnosed with serious heart conditions already but haven’t showed up in routine tests or had continued to exercise with inappropriate workload. In Latvia junior athletes […]

More than half of acute coronary syndromes (ACS) occur in subjects with no significant coronary stenosis.1 In view of the number of patients dying each year from a heart attack, the question of identifying these patients is of primary importance. A large body of evidence currently exists, indicating that total coronary atheroma burden (TOCAB) – the […]
Left main Stenosis Stenting Normalizes Wall Shear Stress of Ascending Aorta in Bicuspid Aortic Valve
Heart International. 2020;14(2):121-2 DOI: https://doi.org/10.17925/HI.2020.14.2.121
Bicuspid aortic valve (BAV) represents the most common congenital cardiac anomaly, with a prevalence ranging between 1% and 2% in the general population.1 BAV is known to be associated with dilation and dissection of the ascending aorta, and the significantly higher shear forces seem to have a pivotal role on the development of such complications.2 Nowadays, patients […]
