Öğe Acute myocardial infarction in a 14-year-old male with normal coronary arteries(Lippincott Williams & Wilkins, 2007) Tatli, Ersan; Surucu, Huseyin; Fatih, Ozcelik[Abstract Not Available]Öğe The Association between Left Ventricular Diastolic Dysfunction and Increased Aortic Stiffness Can Be Explained by Possible Neurohumoral Mechanisms(Wiley-Blackwell Publishing, Inc, 2010) Surucu, Huseyin; Tatli, Ersan; Boz, Hakki; Meric, MehmetObjective: In our study, we tried to find an answer to the question How could the association between left ventricular diastolic dysfunction (LVDDF) and increased aortic stiffness (IAS) be explained? Methods: Cases without coronary artery disease (CAD) were divided into three groups according to their left ventricular (LV) inflow patterns and their LV basal-lateral annulus pulsed-wave tissue Doppler imaging (pw-TDI). Group 1 (n = 38) represented the normal LV inflow pattern while Group 2 (n = 54) represented impaired LV relaxation and Group 3 (n = 18) represented pseudonormalization. Aortic diameters were measured by using M-mode at a level that is 3 cm above the aortic valve. Aortic strain (AS) and aortic distensibility (AD) were calculated by using aortic diameters and pulse pressure. Results: In Group 3, AS was lower compared to Groups 1 and 2 (respectively P < 0.001, P = 0.040). AS was also lower in Group 2 compared to Group 1 (P = 0.012). AD was higher in Group 1 compared to Groups 2 and 3 (respectively P = 0.01, P < 0.001). Early diastolic velocity of aortic pw-TDI was higher in normal LV inflow compared to Groups 2 and 3 (respectively P = 0.022, P = 0.050). Unfortunately, none of echocardiographic parameters that evaluate LV and aortic functions together (stroke volume, pulse pressure/stroke volume, pulse pressure/stroke volume index) were different among the groups. Conclusion: The results of our study clearly showed the association between LVDDF and IAS in cases without CAD. Additionally, it was concluded that this togetherness could be explained not by hemodynamic factors but by possible neurohumeral mechanisms.

Disease manifestations consist of recurrent oral and genital ulceration, skin lesions, and relapsing ocular inflammation. Arterial involvement is an uncommon complication of Behcet's disease, and it most frequently affects the abdominal aorta followed by femoral artery, and the pulmonary artery. Coronary lesions in Behcet's disease have been little reported in the literature. A-36-year-old female with 6-year history of Behcet's disease was hospitalized with ectasia of the left main coronary artery. This unusual vascular complication Behcet's disease is presented.Öğe Effects of coronary collateral vessels in left ventricular segmental motions and myocardial viability using color kinesis dobutamine stress echocardiography(Saudi Med J, 2006) Tatli, Ersan; Surucu, Huseyin; Oztekin, Erkan; Ulucay, Abdullah; Ozcelik, Fatih; Ozer, Orhan; Aktoz, MeryemObjective: To detect the functional importance of coronary collaterals, which develop after acute myocardial infarctions (AMI). Methods: Forty patients with acute AMI whose coronary angiography demonstrated a total occlusion of the left anterior descendant (LAD) artery were included in the study, between January 2003 and June 2004. All of the study patients underwent coronary angiography and left ventriculography using standard Judkins techniques (Phillips Integris-3000). Left ventricular (LV) free walls were divided into 5 segments, and all of these segments motions were evaluated then LV free wall motion score index (WMSI) was calculated. The study patients were divided into 2 groups: good (Rentrop 3; group I; n = 14) and poor coronary collateral circulation (Rentrop 0-2; group II; n = 26) according to the Rentrop grading. Then, color kinesis dobutamine stress echocardiography (CK-DSE) was performed to all patients with standard techniques 6 weeks after AMI. Results: There were no significant differences for age, gender, risk factors for the coronary artery disease and use of the fibrinolytic therapy between the groups. There were no significant statistical differences for angiographic WMSI, left ventricular ejection fraction (LVEF), end-diastolic volume, end-systolic volume and end-diastolic pressures between the 2 groups. No difference was detected between Group I and II for initial EF, WMSI and peak dose WMSI in CK-DSE procedure. Viability was determined in all of the 14 patients in group I (100%) and 12 of 26 patients in group II (46%) (p=0.03). Conclusion: In early periods of an AMI genesis of the coronary collateral circulation does not affect left ventricular global and regional systolic functions, but increase viability quite significantly. According to our findings early revascularization could be carried out in patients with good coronary collateral circulation without doing any test for viability.Öğe Evaluation of Left Ventricular Circumferential Contraction Functions in Obese Patients(Wiley-Blackwell, 2010) Surucu, Huseyin; Tatli, Ersan; Boz, Hakki; Meric, MehmetBackground: We aim to evaluate left ventricular (LV) function abnormalities, especially circumferential contraction functions, in obese patients. Method: Cases without coronary artery disease (CAD) were divided into two groups according to their body mass indexes (BMI). Results: Female predominance (P = 0.002), systolic blood pressure (BP) (P = 0.001), diastolic BP (P = 0.001), waist circumference (P < 0.001), left atrium (P < 0.001), LV end-diastolic diameter (P = 0.046), LV mass index (P = 0.001), and LV stroke volume (P = 0.016) were prominent in obese patients (BMI >= 27). In obese patients, transmitral late velocity (P = 0.005) was prominent, and pulmonary vein antegrade diastolic velocity (PV-D) (P = 0.002) and mitral annular early diastolic pulsed-wave tissue Doppler imaging (pw-TDI) velocity (annular Ea) (P = 0.032) were lower. Transmitral late velocity was positively correlate with stroke volume (P = 0.029) and systolic BP (P < 0.001). Negatively correlation between PV-D and diastolic BP (P = 0.046) was found. And also, annular Ea velocity was negatively correlate with systolic BP (P = 0.017) and diastolic BP (P = 0.031). These findings may reflect LV longitudinal contraction abnormalities (LVLCA) and underlying mechanism that is responsible for LVLCA, may be volume and afterload alterations. However, LV circumferential contraction functions that evaluate by using pw-TDI, were not different among the groups. Conclusion: In obese patients without CAD, it was clearly said that while LVLCA were evident, LV circumferential contraction abnormalities were not. This differentiation may be explained by subepicardial myocardial fiber that is responsible for LV circumferential contractions is supplied by coronary arteries, subendocardial myocardial fiber that is responsible for LV longitudinal contractions, is supplied by systemic circulation via LV cavity penetration.
