Key result
In an anatomical study of 30 aborted human fetal hearts, right coronary dominance was present in 60% of cases, left coronary dominance in 36.66%, and balanced co-dominance in 3.33%.
Why the study?
Increasing rates of myocardial infarction at younger ages prompted investigation into anatomical vascular variations, specifically coronary dominance patterns in aborted human fetal hearts.
Observational (n=30)
No
In Indian aborted fetal hearts, right coronary dominance is the most common anatomical variant (60%), followed by a relatively high rate of left dominance (36.66%).
Coronary dominance patterns may refine MI risk stratification; extends fetal anatomy data but leaves open adult validation.
Increasing incidences of myocardial infarction and decreasing age at which they are occurring has forced many researchers to do in depth study pertaining to the anatomical variations in the vascular pattern of heart. Coronary dominancy of the heart will determine whether the territory of the heart supplied by the posterior inter ventricular artery will receive blood from right coronary artery or left coronary artery or both. Present study was conducted to explore the variations in the coronary dominant pattern in the aborted human fetal hearts. Right and left coronary arteries in 30 aborted human fetal hearts were thoroughly dissected from their commencement from the corresponding aortic sinus till their termination. The coronary dominance was determined on the basis of origin of posterior inter ventricular artery. We found 60% cases of right coronary dominance, 36.66% cases of left coronary dominance and 3.33% cases of balanced coronary dominance/ coronary co-dominance. Data shows variations in the vascular dominancy pattern of heart can be critically important for the cardiac surgeons, cardiologists as well as interventional radiologists while performing investigational or operative procedures.

Ashish Khokhariya (2022) conducted an observational in Aborted human fetuses (n=30). Anatomical dissection of coronary arteries was evaluated on Coronary dominance pattern based on the origin of the posterior interventricular artery. In an anatomical study of 30 aborted human fetal hearts, right coronary dominance was present in 60% of cases, left coronary dominance in 36.66%, and balanced co-dominance in 3.33%.
