ABSTRACT: OBJECTIVES Multidetector computed tomography (MDCT) angiography, which is used for native coronary vessels and bypass graft (CABG) imaging is a non-invasive test. Here, we aimed to compare the diagnostic accuracy of 16- and 64-slice MDCT for graft patency and stenosis. METHODS A total of 129 consecutive patients with CABG who underwent both MDCT (58 patients with 16-slice, 71 patients with 64-slice) and invasive angiography were included. Median time interval between the two procedures was 12 days (range 3-28 days). Bypass grafts were evaluated concerning patency and presence of stenosis ≥50%. Both 16- and 64-slice MDCT results were compared with invasive angiography. RESULTS Overall diagnostic accuracy for the detection of graft patency was 95% for 64-slice vs 92% for 16-slice MDCT. By analyzing the 173 grafts by 64-slice vs 153 grafts by 16-slice MDCT that could be evaluated, sensitivity, specificity, positive predictive values (PPV) and negative predictive values (NPV) of the MDCT for visualization of graft patency were 90, 98, 90 and 98% vs 87, 97, 94 and 93%, respectively. The accuracy of MDCT for the detection of significant graft stenosis was relatively low (sensitivity, specificity, PPV and NPV were 67, 98.6, 50 and 98.6% with 16-slice vs 80, 98.1, 72.7 and 98.7% with 64-slice). CONCLUSIONS This study showed that the 16-slice has a diagnostic accuracy comparable with the 64-slice system for graft patency and can still be used for this purpose if newer systems with improved performance are not available on-site. On the other hand, by the virtue of better image quality, the 64-slice MDCT demonstrates significant graft lesions with higher sensitivity.

ABSTRACT: Diabetes mellitus (DM) is strongly associated with increased risk of coronary artery disease (CAD). The aim of this study was to determine differences in presence, extent and morphology of coronary atherosclerotic plaques (CAP) detected by multidetector computed tomography (MDCT) between symptomatic patients with and without diabetes.
The CAPs (calcified, non-calcified, mixed) were compared between patients with/without diabetes (104/257 DM; mean age 58.6 +/- 11 y; 46.3% male) who underwent dual-source 64-slice MDCT for evaluation of CAD. Severity, extent and morphology of CAPs were determined per each segment.
Critical coronary stenosis was higher in patients with diabetes (33.7% vs. 19.6%) after adjustment for all risk factors (P = 0.022). Patients with DM had a higher prevalence and extent of CAP compared to non-diabetic subjects (87.5% vs. 43.8%, 4.8 +/- 3.5 vs. 1.9 +/- 2.7, respectively; P < 0.001). Noncalcified and mixed CAP were more prevalent in patients with diabetes as compared to those without diabetes (2.61 +/- 2.63 vs. 0.86 +/- 1.69, 0.81 +/- 1.6 vs. 0.35 +/- 0.96, respectively, P < 0.001). Patients with DM tended to have higher prevalence of significant 1-, 2- and 3-vessel disease (P = 0.006).
Among individuals referred for the evaluation of CAD, those with DM had a higher risk of coronary stenosis and overall increased CAP burden independent from other cardiovascular risk factors shown by MDCT. Further studies are needed to evaluate the prognostic value of different plaque compositions observed in patients with diabetes.

ABSTRACT: The aim of this study was to investigate the diagnostic accuracy of 16-slice multislice, multidetector computed tomography (MDCT) angiography for the evaluation of grafts in patients with coronary artery bypass grafting (CABG).
Fifty-eight consecutive patients with CABG who underwent both MDCT and conventional invasive coronary angiography were included. The median time interval between the 2 procedures was 10 days (range, 1-32 days). The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of MDCT for the detection of occluded grafts were calculated. The accuracy of MDCT angiography for detecting significant stenoses in patent grafts and the evaluability of proximal and distal anastomoses were also investigated.
Optimal diagnostic images could not be obtained for only 3 (2%) of 153 grafts. Evaluation of the remaining 150 grafts revealed values for sensitivity, specificity, PPV, NPV, and diagnostic accuracy of the MDCT angiography procedure for the diagnosis of occluded grafts of 87%, 97%, 94%, 93%, and 92%, respectively. All of the proximal anastomoses were optimally visualized. In 4 (8%) of 50 patent arterial grafts, however, the distal anastomotic region could not be evaluated because of motion and surgical-clip artifacts. The accuracy of MDCT angiography for the detection of significant stenotic lesions was relatively low (the sensitivity, specificity, PPV, and NPV were 67%, 98%, 50%, and 99%, respectively). The number of significant lesions was insufficient to reach a reliable conclusion, however.
Our study showed that MDCT angiography with 16-slice systems has acceptable diagnostic performance for the evaluation of coronary artery bypass graft patency.

ABSTRACT: Total white blood cell (WBC) count has been consistently shown to be an independent risk factor and predictor for future cardiovascular outcomes, regardless of disease status in coronary artery disease (CAD). The purpose of this study is to evaluate the relationship between total WBC count and the presence, severity and extent of coronary atherosclerosis detected in subjects undergoing multislice computed tomographic (MSCT) coronary angiography for suspected CAD.
A total of 817 patients were enrolled in this cross-sectional study. Non-significant coronary plaque was defined as lesions causing £ 50% luminal narrowing, and significant coronary plaque was defined as lesions causing 〉 50% luminal narrowing. For each segment, coronary atherosclerotic lesions were categorized as none, calcified, non-calcified and mixed. All images were interpreted immediately after scanning by an experienced radiologist.
An association between hypertension, diabetes mellitus, age, gender, hyperlipidemia, smoking, total WBC counts and coronary atherosclerosis was found when patients were grouped into two categories according to the presence of coronary atherosclerosis (p 〈 0.05). Although plaque morphology was not associated with total WBC counts, the extent of coronary atherosclerosis was increased with higher total WBC quartiles (p = 0.006). Patients with critical luminal stenosis had higher levels of total WBC counts when compared to patients with non-critical luminal narrowing (7,982 ± 2,287 vs 7,184 ± 1,944, p 〈 0.05).
Our study demonstrated that total WBC counts play an important role in inflammation and are associated with the presence, severity and extent of coronary atherosclerosis detected by MSCT. Further studies are needed to assess the true impact of WBC counts on coronary atherosclerosis, and to promote its use in predicting CAD.

ABSTRACT: The iron loading related to erythrocyte transfusions is the major cause of morbidities and mortalities in patients with β-thalassemia major (β-TM). Deferasirox, an orally active iron chelator, has been reported to cause serum creatinine increases in addition to acute renal failures in elderly patients with comorbidities. The nefrotoxicities in patients using deferasirox, despite the facts that the drug is minimally excreted from kidneys and its effective chelation of iron from liver and heart, may rise the question of decomparmentalization of iron from these organs to kidneys. Thirteen patients with β-TM were included in the study (mean age 18.5 ± 7.5 years [9-33 years]). The patients received deferasirox in a dose of 34.3 ± 6.5 mg/kg [17-37 mg/kg]. Four patients (31%) exhibited consecutive increases in serum creatinine greater than 33% above baseline twice during the follow-up period. The results indicated that the earliest iron chelation starts in liver in patients receiving deferasirox. Additionally, by the 6th month of deferasirox, the status of cardiac and renal iron in chronically transfused patients with β-TM were preserved. This may indicate that the serum creatinine increases may not be attributed to iron decompartmantalization from other organs to kidneys.

ABSTRACT: We investigated the evaluability of left atrial appendix by dual source coronary CT angiography and analyzed morphologic features.
We included 106 consecutive patients who underwent coronary CT angiography for various indications. Technical parameters were slice thickness 0.6 mm, reconstruction interval 0.3mm, gantry rotation time 165 ms. Images were reconstructed from 10% to 100% R-R intervals at 10% intervals to evaluate the left atrial appendix and 4-D inspace software was used for analysis. We recorded the R-R intervals when the left atrial appendix was at maximum and minimum volume. We also evaluated visibility of appendix at R-R intervals. Maximum appendix volume was calculated. Atrial appendices were classified morphologically based on number of chambers (types 1-3) seen on volume rendered images.
There were 60 male and 46 female patients in the study group and, mean age was 55±13. Mean heart rate was 72 (ranges 47-110). Left atrial was evaluable at maximum and minimum volume by coronary CT angiography in all patients. We noted types 1-3 appendix in 29 (27%), 73 (69%), and 4 (4%) patients, respectively. Mean R-R intervals at maximum and minimum volume were 40%±6 (95% CI; 28-52%) and 95%±5 (95% CI; 85-5%), respectively. Mean appendix maximum volume was 7±4 cm3. Appendix contours were mildly, moderately and severely irregular in 10 (9%), 58 (55%), 38 (36%) patients, respectively.
Left atrial appendix was visualized in all patients independent of heart rate at maximum and minimum volumes. Volume rendered CT images can allow excellent depiction of left atrial appendix morphology and classification. Presence of moderate and severe irregularity of appendix contour in most of the patients may be the cause of slow flow. This morphologic appearance may be the underlying reason for the propensity to atrial appendix thrombus formation.

ABSTRACT: There are limited data on the posttransplantation pharmacological treatment of iron overload in ex-thalassemic patients and the current approach is phlebotomy. The authors chelated 2 ex-thalassemic patients after hematopoietic stem cell transplantation with deferasirox for 6 and 24 months. Although serum ferritin levels decreased, cardiac and hepatic iron load, measured by T2* magnetic resonance imaging (MRI), showed decrease in iron overload in these organs. The drug was tolerated well by both patients and no adverse effect on donor hematopoiesis was observed. This preliminary study demonstrates that deferasirox is well tolerated in these patients and will be a good potential therapy when more data have been obtained from larger studies.

ABSTRACT: This study aimed to compare the results of angiocardiography and cardiovascular magnetic resonance imaging in the assessment of pulmonary regurgitation following repair of tetralogy of Fallot.
We prospectively studied 37 patients with repaired tetralogy of Fallot. After routine examination cardiovascular magnetic resonance imaging (CMR) and cardiac catheterization and angiography were performed. Pulmonary regurgitation (PR) was classified according to the following criteria, using a left lateral angiogram of the main pulmonary artery; insufficiency jet is limited to right ventricular outflow tract (mild); jet reaches the body of right ventricle (moderate); jet fills the apex of the right ventricle (severe).
Pulmonary regurgitation determined by angiocardiography and CMR was severe in 51.4% and 32.4%, moderate in 27% and 40.5%, and none or mild in 21.6% and 27% of patients respectively. The ability of semi-quantitative estimation of PR determined by cardiac catheterization to distinguish between mild, moderate and severe pulmonary regurgitation was shown to have significant correlation with pulmonary regurgitant fraction obtained by CMR.
Angiography obtained during invasive study can be used for the diagnosis and follow-up of pulmonary regurgitation confidently in patients with repaired tetralogy of Fallot and residual pulmonary regurgitation.

ABSTRACT: We investigated the association between atherosclerosis of the thoracic aorta and the severity and extent of coronary atherosclerosis detected by multidetector computed tomography (MDCT) coronary angiography. In 122 patients, atherosclerotic plaque was scored from 0 to 4 points by the percentage of the luminal surface at the cross-sectional area of proximal, mid, and distal segments of the descending aorta. Critical coronary atherosclerosis was defined as lesions causing >50% luminal narrowing. Atherosclerotic plaque score of the descending aorta was associated with the severity (noncritical: 2.95 +/- 1.45 vs critical: 4.09 +/- 2.25, P < .001) and extent of coronary atherosclerosis (Kruskal-Wallis test, P < .005). Logistic regression revealed that aortic plaque score was as an independent risk factor associated with the severity of coronary artery disease (OR 1.32, 95% CI 1.01-1.73, P <.05). Atherosclerotic plaque burden of the descending aorta was associated with the extent and severity of coronary atherosclerosis.

ABSTRACT: Tissue Doppler imaging (TDI) can detect myocardial dysfunction related to iron load in patients with beta-thalassemia major (TM). We aimed to assess the efficacy of pulsed-wave TDI (PW-TDI) in predicting myocardial iron load in patients with TM using T2* magnetic resonance (MR) as the gold-standard non-invasive diagnostic test. 33 asymptomatic TM patients, mean aged 18 +/- 6 years (6-31) with normal left ventricular (LV) global systolic function were evaluated by conventional echocardiography and PW-TDI. Results were compared with 20 age and sex-matched controls. TDI measures included myocardial systolic (Sm), early (Em) and late (Am) diastolic velocities at basal and middle segments of septal and lateral LV wall. Myocardial iron deposition were measured in 29/33 patients by T2* MR. TM patients were also subgrouped according to those with iron load (T2* <or= 20 ms) and those without (T2* > 20 ms). Mean T2* was 12.3 +/- 7.8 ms (4-31.3). Abnormal myocardial iron load (T2* < 20 ms) was found in 25/29 (86%) patients. The following TDI measures were lower in patients than in controls: basal septal Em (P < 0.001) and Am (P < 0.05), mid-septal Am (P < 0.05), mid-lateral LV wall Sm (P < 0.05) and Am (P < 0.05). Regional myocardial dysfunction were more prominent in patients with T2* <or= 20 ms. Mid-septal Sm and Em significantly correlated with mid-septal T2*(r = 0.44, P = 0.023 and r = 0.54, P = 0.004, respectively). The PW-TDI parameters and the cut-off values for predicting presence of myocardial iron load were determined. PW-TDI technique was found both sensitive and specific in predicting presence of myocardial iron load in TM patients with normal LV global systolic function. Therefore, it can be used for screening of TM patients.

ABSTRACT: In this study, we aimed to evaluate the incidence of pulmonary abnormalities and document early follow-up results in subjects undergoing multislice computed tomography coronary angiography for the assessment of coronary artery disease.
In this retrospective analysis, 1206 patients including 701 men (58.1%) with a mean age of 58.75 (SD, 11.4) years were involved in the study who underwent coronary multislice computed tomography imaging with a 64-slice dual-source scanner. Pulmonary abnormalities were reported as nodules, pulmonary mass, emphysema, bullae, atelectasia, bronchiectasia, pleural effusion, pulmonary fibrosis, and other findings.
In total, 186 pulmonary abnormalities were detected in 171 patients (14.1%). Of those, 90 (48.4%) were pulmonary nodules, and 30 (16.1%) were emphysema. Also, we report 3 cases of lung cancer, and 1 case of breast cancer. Early follow-up results revealed stable pulmonary findings.
Multislice computed tomography can give important clues including diseases regarding the pulmonary system. It is essential for the reporting practitioner to review the entire scan for pulmonary pathological findings.

ABSTRACT: PURPOSE To detect pathologies in coronary arteries by computed tomography angiography (CTA) in survivors of childhood Hodgkin's lymphoma who have been treated with radiotherapy and/or cardiotoxic agents. PATIENTS AND METHODS Patients with HL who have been in remission for at least 2 years after completion of therapy were included. CBC, lipid profile, urine analysis, brain natriuretic peptide, troponin-T, creatinine kinase-myocardial band, ECG, telecardiography, echocardiography, and CTA of the patients were performed. Cardiac vascular abnormalities were noted. Results A total of 119 patients were included in the study. In 19 patients (16%), we found coronary artery abnormalities. There was a significant difference between the patients who received mediastinal radiotherapy and those who did not (P = .02). By multivariate analysis, in patients receiving mediastinal radiotherapy the risk of developing a coronary artery abnormality was found to increase 6.8 times compared with patients who did not receive mediastinal radiotherapy (P = .009). Stent implantation was performed in a 28-year-old patient because of critical stenosis in right coronary. In two patients some irregularities were detected both in CTA and conventional angiography, and they remained in close follow-up. A 22-year-old patient whose CTA showed critical stenosis in his left anterior descending artery refused the conventional angiography. CONCLUSION To our knowledge, this is the first large study using CTA for detection of coronary abnormalities in patients treated for HL in pediatric age group. Coronary CTA is a minimally invasive tool for early diagnosis of coronary artery disease in patients who were treated with mediastinal radiotherapy and/or cardiotoxic chemotherapy.

ABSTRACT: A 33-year-old male patient presented with complaints of atypical chest pain and exertional dyspnea of two-month history. Examinations to uncover these symptoms (physical examination, blood tests, electrocardiography, transthoracic echocardiography, coronary angiography, right heart catheterization) showed no abnormality, except for echocardiographic appearance of hypoechogenic areas suggesting widespread pericardial effusion involving the anterior and posterior cardiac walls and mild pulmonary stenosis. Cardiac magnetic resonance imaging (MRI) performed for further evaluation of the pulmonary gradient revealed fatty infiltration surrounding the whole heart, infiltration into the myocardium, and causing indentation of the proximal pulmonary artery. Since no pathologic condition associated with this radiologic appearance could be found, lipomatous infiltration was thought based on these cardiac MRI findings.

ABSTRACT: Cytokine gene polymorphisms have been implicated as potential genetic risk factors for cardiovascular diseases (CVDs). Atherosclerosis and left ventricular hypertrophy (LVH) are surrogate markers for CVDs in uremic patients. The aim of this study was to assess the role of cytokine gene polymorphisms in carotid intima-media thickness (CIMT) and left ventricular mass index (LVMI) progression in nondiabetic hemodialysis (HD) patients.
About 102 nondiabetic patients on maintenance HD were included in this study. Patients were followed up for 2 years. Genetic polymorphisms of TNF-alpha (-308 G/A, -238A/G) and IL-10 (-1082 A/G, -819 C/T, -592 A/C) were determined by polymerase chain reaction. Biochemical parameters and inflammatory markers and ambulatory blood pressure (BP) measurements were determined during the study period. CIMT and LVMI were also determined at baseline and after the first and second year.
Cardiovascular risk factors did not differ between TNF-alpha -308 high-/low-producer genotype groups. However, CIMT and LVMI progression were detected at higher levels in patients with high-producer genotypes (AA+AG) than in patients with the low-producer genotype (GG) during the study period. The TNF-alpha -308 G/A polymorphism was closely associated with C-reactive protein (CRP), a marker of systemic inflammation in the study population. Analysis also showed that the combination of high production of TNF-alpha and low production of IL-10 was associated with higher average IMT and LVMI progression and elevated average CRP levels compared with a combination of low production of TNF-alpha and high production of IL-10.
Polymorphisms in inflammatory genes may represent an additional factor affecting inflammation and CVD progression in nondiabetic HD patients.

ABSTRACT: Cardiac failure due to myocardial iron overload is the most common cause of death in beta-thalassemia patients. Multi/ two echo times-turbo field echo (TE-TFE) magnetic resonance imaging (MRI) is considered the gold standard technique in the evaluation of myocardial iron accumulation. However, multi TE-TFE technique is not available in all scanners. The aim of our study was to show the role of black blood dualecho cardiac triggered TFE in the assessment of myocardial iron overload.
Sixteen beta-thalassemia major patients (10 males) with a mean age of 19 years who were receiving parenteral deferoxamine and oral deferiprone treatment were included in this study. Baseline measurement of myocardial T2* values were < 20 ms in all patients. Cardiac MRI was performed after 6 months, 12 months, and 18 months with the same technique.
The average baseline value of T2* was 8.2 +/- 3.6 ms. After treatment of combined deferoxamine and deferiprone, the average measurements of myocardial T2* at 6, 12, and 18 months were 11.3 +/- 6.0, 13.6 +/- 7.5, and 15.7 +/- 7.4 ms, respectively (P < 0.05). The basal ejection fraction (EF) value was 49 +/- 8.7%. The EFs were 54.4 +/- 11% at 6 months, 54.8 +/- 6.9% at 12 months, and 58.6 +/- 3.6% at 18 months of followup (P > 0.05).
Cardiac MRI with dual TE-TFE technique can be used to determine myocardial iron accumulation and response to the chelation treatment.

ABSTRACT: Patients with end-stage renal disease have a very high prevalence and extent of arterial calcification. A number of studies suggest that similar pathophysiologic mechanisms are responsible for development and progression of calcification of atherosclerotic plaque and bone formation. Fetuin-A is a potent calcification inhibitor and is expressed in bone, with not-yet well-defined functions. The aim of this study was to investigate the relation between bone mineral densitometry parameters, coronary artery calcification, and serum fetuin-A levels. In a cross-sectional design, we included 72 maintenance hemodialysis (HD) patients and 30 age- and gender-matched healthy controls. Serum fetuin-A levels were studied both in maintenance HD patients and healthy controls. Maintenance HD patients had radius, hip, and lumbar spine bone mineral density (BMD) assessed by dual-energy X-ray absorptiometry and coronary artery calcification score (CACS) measured by electron-beam computed tomography. The associations between site-specific BMD parameters, CACS, and serum fetuin-A levels were studied in maintenance HD patients. CACS, mass, and volume of plaques in coronary arteries were significantly higher in patients with a T-score below -2.5 than above in the proximal region of the radius, neck and trochanter of the femur, and the lumbar spine. Mean serum fetuin-A concentration was 0.636 +/- 0.118 g/L in maintenance HD patients and it was less than healthy controls (0.829 +/- 0.100 g/L, P < 0.0001). CACS, mass, and volume of plaques in coronary arteries correlated significantly with the serum fetuin-A levels. Moreover, significant positive correlations were shown between the serum fetuin-A levels, BMD values, and T-scores of proximal radius, neck, and trochanter of the femur, but not with the lumbar spine. The present study demonstrates an association between serum fetuin-A levels, coronary artery calcification, and bone mineral densities--except for the lumbar spine, in maintenance HD patients. However, the results should be interpreted with caution because of the cross-sectional design of the study.
