    Coronary artery anomalies and dominance: data from a single center in Turkey
    (Edizioni Minerva Medica, 2022) Akkaya, Hasan; Gunturk, Ertugrul E.
    BACKGROUND: Coronary artery anomalies (CAA) are found in 0.2% to 1.3% of coronary angiograms. The aim of the presented study was to describe congenital CAA and their variations, also identifying the prevalence of these anomalies and coronary artery dominance in our center. METHODS: A total of 7858 patients were included in the study retrospectively between August 2015 and March 2020. Patients undergoing coronary angiography (CAG) were reviewed by at least 2 independent and experienced observers. The Angelini's CAA Classification method was used to classify patients. Coronary dominance was determined according to the artery from which the posterior desending artery originated. RESULTS: CAA was detected in 88 (1.1%) out of 7858 patients. Of these patients, 73 (82.9%) had anomalies of origination and course called group A, 7 (7.9%) had anomalies of intrinsic coronary arterial anatomy called group B, and 8 (9.1%) had anomalies of coronary termination called group C. Anomalous collateral vessels called group D were not detected. RCA dominance was N.=5579 (70.99%), Cx dominance was N.=1021 (12.99%), and codominancy was N.=1258 CONCLUSIONS: The incidence of CAA was 1.1% in total and is compatible with other major studies. According to the Angelini CAA clasification, group B anomalies are observed more frequently than other studies. Cx dominance is (Cite this article as: Akkaya H, Giintiirk EE.

    Relationship between echocardiography and arterial stiffness parameters and chorodial thickness in healthy subjects
    (Edizioni Minerva Medica, 2022) Akkaya, Hasan; Zor, Kursad R.; Gunturk, Ertugrul E.; Kucuk, Erkut; Yildirim, Gamze
    ABSTR A C T BACKGROUND: Choroid is one of the most vascularized tissues of the body. Enhanced depth imaging optical coher-ence tomography (EDI-OCT) is the diagnostic method for choroid imaging. An increase in arterial stiffness, one of the important determinants of vascular aging, is a prognostic predictor of cardiovascular mortality. Carotid-femoral pulse wave velocity (CFPWV) is the gold standard method for the detection of arterial stiffness and has a high predictive value for undesirable cardiovascular events. The aim of our study was to investigate whether there is a relationship between choroidal thickness and echocardiographic findings, CFPWV, arterial stiffness, aortic distensibility and other basic pa-rameters in healthy middle-aged subjects. METHODS: The study included 80 healthy individuals aged 30-60 years. Firstly, echocardiographic and arterial stiffness levels of volunteers were evaluated, and choroidal thickness was determined by EDI-OCT. The relationship between choroidal thickness and other parameters was evaluated by Pearson correlation test. RESULTS: A total of 80 healthy volunteers (35 females, 43%) were included in the study. The mean age was 42.40-17.68 years (range, 31-60 years). It was found that there were a negative correlation between choroid and age (r=-0.80, P<0.01), left ventricular deceleration time (r=-0.72, P<0.01), isovolumic relaxation time (r=-0.76, P<0.01), ee (r =-0.68, P<0.01), annular late diastolic velocity (r=-0.25, P<0.05), CFPWV (r=-0.70, P<0.01) and aortic stiffness (r=-0.76, P<0.01). There was a significant positive correlation between choroid and aortic distensibility (r=0.81, P<0.01). There was no difference between the genders in terms of choroidal thickness (t[77]=0.47, P>0.05). CONCLUSIONS: Correlation between advanced age, left ventricular diastolic dysfunction, increased arterial stiffness parameters, decreased aortic distensibility and choroidal thinning were observed.
