Öğe Accessory mitral valve tissue manifesting cerebrovascular thromboembolic event in a 34-year-old woman(Elsevier Sci Ireland Ltd, 2003) Yetkin, E; Turhan, H; Atak, R; Senen, K; Cehreli, SAccessory mitral valve tissue is an extremely rare congenital cardiac anomaly. Most of the cases reported in the medical literature were associated with left ventricular outflow tract obstruction. The majority of cases of accessory mitral valve tissue, causing left ventricular outflow tract obstruction, occur in association with other congenital cardiac anomalies. In this reported case, a patient with accessory mitral valve tissue complicated with thromboembolic cerebrovascular event is presented. The patient also had an associated idiopathic hypertrophic subaortic stenosis. (C) 2002 Elsevier Science Ireland Ltd.

Although cardiac involvement is not infrequent as a manifestation of Behcet's disease, coronary arteritis is very rarely reported. We suggest that the diagnosis of coronary arteritis should be considered in patients presenting acute myocardial infarction especially in young patients as underlying cause.

This measurement has been significantly correlated with flow velocity measured invasively by use of a Doppler flow wire. Coronary artery ectasia or aneurysm (CEA) is thought to be present in patients with a slow blood flow. In this study, we aimed to assess the relationship between the ectasia size or ectasia ratio and TIMI frame count in patients with CEA. The study population included 58 patients with isolated CEA of the right coronary artery. In patients with CEA, an ectasia ratio was calculated as diameter of the ectatic segment/diameter of the adjacent normal segment. According to the ectasia ratio, ectatic vessels were divided into two groups: ectasias with a 1.5- to 2.0-fold increase (group A) and more than 2.0-fold increase (group B) in normal vessel diameter. Patients with a significant stenotic lesion (> 50%) in the ectatic vessel were excluded. The control group was formed from a matched population of 35 patients with angiographically proven normal coronary arteries. Characteristics of the ectasia and control groups are similar. The TIMI frame counts for the right coronary artery (RCA) were significantly higher in the ectasia group as compared with the control group (43 +/- 12 vs 23 +/- 8, P < 0.001). The ectasia group had 38 patients in group A and 20 patients in group B. The TIMI frame counts were significantly higher in group B than in group A (43 +/- 10 vs 51 +/- 15, P < 0.05). The TIMI frame count of the RCA showed a significant correlation with the ectasia ratio and the maximum diameter of the ectatic segment (r = 0.578, P < 0.001 and r = 0.435, P < 0.001, respectively). Our data suggest that TIMI frame count measurement depends on the ectasia size or ectasia ratio, and an increased ectasia ratio is markedly associated with decreased TIMI frame counts in patients with CEA.Öğe Effects of co-existence of coronary stenosis and the extent of coronary ectasia on the TIMI frame count in patients with coronary artery ectasia(Int Heart Journal Assoc, 2005) Kosar, F; Acikgoz, N; Sahin, I; Topal, EU; Gunen, H; Ermis, N; Cehreli, SThe measurement of the thrombosis in myocardial infarction (TIMI) frame count is a simple method for evaluating coronary blood flow. Although it is well known that slow coronary flow is present in patients with coronary artery ectasia (CAE), the effects of coexisting stenosis and the severity of ectatic involvement on coronory flow have not been adequately studied. Thus, we examined (1) the effect of coexistence of obstructive coronary artery disease on TIMI frame count (TFC) and (2) the relation between the severity of ectatic involvement and TFC in patients with CAE. Ninety-seven study patients with CAE were examined in two steps to determine if they were appropriate in terms of the aim of this study. In the first step, ectasias were divided into three groups: an isolated CAE group, a CAE group with coexisting nonsignificant stenosis, and CAE with coexisting significant stenosis. In the second step, ectasias were subdivided into three groups: CAE with one segment, two segments, and three segments (or diffuse) involvement. The TIMI frame counts for the right coronary artery (RCA), the left circumflex coronary artery (LCx), and the left anterior descending artery (LAD) in the ectasia,roup were significantly higher than that of the control group (P < 0.001 P < 0.05, P < 0.05, respectively). The presence of coexisting nonsignificant stenosis or coexisting significant stenosis in patients with CAE did not influence TFC (P > 0.05, For all). In addition, the severity of ectasia involvement, regardless of the localization of ectatic segments and the type of the affected vessel. did not change the TFC (P > 0.05, for all). These results suggest that neither the coexisting stenosis nor the extent of involvement significantly affect TFC in patients with coronary ectasia.Öğe Identification of viable myocardium after anterior myocardial infarction: Comparison of combined low dose dobutamine-nitrate echocardiography and low dose dobutamine stress echocardiography(Lippincott Williams & Wilkins, 2002) Senen, K; Yetkin, E; Ileri, M; Atak, R; Turhan, H; Tandogan, I; Cehreli, S[Abstract Not Available]Öğe Increased levels of soluble adhesion molecules in patients with isolated coronary artery ectasia(W B Saunders Co Ltd, 2003) Turhan, H; Yetkin, E; Erbay, AR; Atak, R; Senen, K; Sasmaz, H; Cehreli, S[Abstract Not Available]Öğe Increased soluble adhesion molecules in patients with slow coronary flow(W B Saunders Co Ltd, 2003) Turhan, H; Yetkin, E; Erbay, AR; Atak, R; Senen, K; Sasmaz, H; Cehreli, S[Abstract Not Available]Öğe Myocardial viability in patients with chronic coronary artery disease and myocardial dysfuncton: Dobutamine stress echocardiography and echocardiography during glucose-insulin-potassium infusion(Lippincott Williams & Wilkins, 2002) Turhan, H; Yetkin, E; Senen, K; Atak, R; Ileri, M; Aksoy, Y; Cehreli, S[Abstract Not Available]Öğe Significance of serum trace element status in patients with rheumatic heart disease - A prospective study(Springernature, 2005) Kosar, F; Sahin, I; Acikgöz, N; Aksoy, Y; Küçükbay, FZ; Cehreli, SIt is known that certain trace elements can affect various heart diseases. In this study, we aimed to evaluate the changes in concentrations of certain serum trace elements in patients with chronic rheumatic heart disease (RHD). Serum analysis of selenium (Se), zinc (Zn), and copper (Cu) trace elements was assayed by atomic absorption spectrophotometry. RHD patients had significantly lower serum concentrations of Se and Zn than control subjects (p < 0.05 and p < 0.001, respectively). However, the serum Cu concentration was significantly higher in RHD patients than in controls (1.93 +/- 0.59 mu g/L vs 1.06 +/- 0.29 mu g/L; p < 0.001). Similarly, the Cu/Zn ratio in RHD patients was higher than in control subjects (4.70 +/- 0.92 vs 1.68 +/- 0.45; p < 0.001). Additionally, no significant correlation was found among these trace element concentrations and the functional capacity classes (p > 0.05). RHD patients had decreased serum Se and Zn element concentrations and increased serum Cu element concentration. We suggest that Se and Zn deficiency might be contributory factors in the development of rheumatic heart disease, and a high Cu concentration and a high Cu/Zn ratio might reflect an ongoing inflammatory process in this disease.
