Introduction: The right heart is more unknown than the left heart, because of less research. With it, its importance is understood, when right heart related diseases are considered. The relation between coronary vascularity and cardiac function is indisputable. There are no research about the effect of coronary dominance, that is anatomical variation merely, upon cardiac function. We investigated difference of right or left domination on right ventricle functions using echocardiography.
Patients and Methods: Working group was contained patients who is done coronary angiography with any indication. Patients were categorized right dominant and non-dominant on coronary angiography. At the same time, the origin of posterior descending artery was determined. There were 2 groups and each of them had 40 patients. Patients who had >50% stenosis on coronary arteries, myocardial infarct previously, cardiac valve disease, chronic obstructive lung disease and pulmoner embolism in past were excluded. Right ventricle functions were investigated using Echocardiography by the same operator. The results were evaluated and calculated average value by two different operators. We used Wilcoxon and Mann-Whitney U Test in evaluation of statistics.
Results: There was no difference between groups in terms of the right ventricular functions; TAPSE (26.47 ± 3.39 vs 25.31 ± 5.19 p= 0.096), FAC (43.19 ± 9.18 vs 47.5 ± 10.7 p= 0.720), GLS by STE (20.55 ± 4.033 vs 19.73 ± 4.71 p= 0.451), RIMP (53.84 ± 11.2 vs 52.93 ± 9.01 p= 0.947).
Conclusion: The effect of right coronary artery dominance on right ventricle functions was not obtained significant.
